Detailed Description

A collection of useful graphics routines for artoolkitX.

arg is the preferred means for drawing camera video images acquired from artoolkitX's video libraries. It includes optimized texture handling, and a variety of flexible drawing options.

Implementations are provided for OpenGL 1.5 and later, OpenGL 3.1 and later, and OpenGL ES 2.0 and later.

The chosen API is determined by the system and context available at the time the first call is made to arglSetupForCurrentContext()/

arg does not depend on any particular window or event handling system.

◆ ARGL_CONTEXT_SETTINGS_REF

ARGL_CONTEXT_SETTINGS_REF

Opaque type to hold ARGL settings for a given OpenGL context.

An OpenGL context is an implementation-defined structure which keeps track of OpenGL state, including textures and display lists. Typically, individual OpenGL windows will have distinct OpenGL contexts assigned to them by the host operating system.

As arg uses textures, buffers, and programs, it must be able to track which OpenGL context a given texture, buffer, or program it is using belongs to. This is especially important when arg is being used to draw into more than one window (and therefore more than one context.)

Basically, functions which depend on OpenGL state, will require an ARGL_CONTEXT_SETTINGS_REF to be passed to them. An ARGL_CONTEXT_SETTINGS_REF is generated by setting the current OpenGL context (e.g. if using GLUT, you might call glutSetWindow()) and then calling arglSetupForCurrentContext(). When you have finished using ARGL in a given context, you should call arglCleanup(), passing in an ARGL_CONTEXT_SETTINGS_REF, to free the memory used by the settings structure.

Since: First appeared in ARToolKit 2.68.

Function Documentation

◆ arglCleanup()

ARG_EXTERN void arglCleanup ( ARGL_CONTEXT_SETTINGS_REF contextSettings )

Free memory used by arg associated with the specified context.

Should be called after no more argl* functions are needed, in order to prevent memory leaks etc.

The library can be setup again for the context at a later time by calling arglSetupForCurrentContext() again.

Parameters

contextSettings A reference to ARGL's settings for an OpenGL context, as returned by arglSetupForCurrentContext(). If NULL, arglCleanup performs no operation.

Since: First appeared in ARToolKit 2.68.

◆ arglDispImage()

ARG_EXTERN void arglDispImage	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		int32_t	viewport[4]
	)

Display an ARVideo image, by drawing it using OpenGL.

This function draws an image from an ARVideo source to the current OpenGL context. This operation is most useful in video see-through augmented reality applications for drawing the camera view as a background image, but can also be used in other ways.

An undistorted image is drawn with the lower-left corner of the bottom-left-most pixel at OpenGL screen coordinates (0,0), and the upper-right corner of the top-right-most pixel at OpenGL screen coodinates (x * zoom, y * zoom), where x and y are the values of the fields cparam->xsize and cparam->ysize (see below) and zoom is the value of the parameter zoom (also see below). If cparam->dist_factor indicates that an un-warping correction should be applied, the actual coordinates will differ from the values specified here.

OpenGL state: Drawing is performed with depth testing and lighting disabled, and thus leaves the the depth buffer (if any) unmodified. If pixel transfer is by texturing and the drawing is done in replacement texture environment mode. The depth test enable and lighting enable state and the texture environment mode are NOT restored before the function returns.

Parameters

contextSettings	A reference to ARGL's settings for the current OpenGL context, as returned by arglSetupForCurrentContext() for this context. It is the callers responsibility to make sure that the current context at the time arglDisplayImage() is called matches that under which contextSettings was created.
viewport	OpenGL-style viewport to be applied prior to drawing, or NULL in which case the viewport will not be set prior to drawing.

Since: First appeared in ARToolKit 2.68.

◆ arglDistortionCompensationGet()

ARG_EXTERN int arglDistortionCompensationGet	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		int *	enable
	)

Enquire as to the enable state of camera lens distortion compensation in arglDispImage.

By default, arglDispImage compensates for the distortion of the camera's acquired image caused by the lens when it draws. This function enquires as to whether arglDispImage is currently doing compensation or not.

Parameters

contextSettings	A reference to ARGL's settings for the current OpenGL context, as returned by arglSetupForCurrentContext() for this context.
enable	Pointer to an integer value which will be set to TRUE if distortion compensation is enabled in the specified context, or FALSE if it is disabled.

Returns: TRUE if the distortion value was retreived, FALSE if an error occurred.

Since: First appeared in ARToolKit 2.71.

◆ arglDistortionCompensationSet()

ARG_EXTERN int arglDistortionCompensationSet	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		int	enable
	)

Set compensation for camera lens distortion in arglDispImage to off or on.

By default, arglDispImage compensates for the distortion of the camera's acquired image caused by the lens when it draws. By calling this function with enabled = FALSE, this compensation will be disabled in the specified drawing context. It may be re-enabled at any time. This function is useful if you need to draw an image, but do not know the extent of the camera's lens distortion (such as during distortion calibration). While distortion compensation is disabled, the dist_factor[] array in a the camera cparam structure passed to arglDispImage is ignored.

Parameters

contextSettings	A reference to ARGL's settings for the current OpenGL context, as returned by arglSetupForCurrentContext() for this context.
enable	TRUE to enabled distortion compensation, FALSE to disable it. The default state for new contexts is enable = TRUE.

Returns: TRUE if the distortion value was set, FALSE if an error occurred.

Since: First appeared in ARToolKit 2.71.

◆ arglGetFlipH()

ARG_EXTERN int arglGetFlipH ( ARGL_CONTEXT_SETTINGS_REF contextSettings )

◆ arglGetFlipV()

ARG_EXTERN int arglGetFlipV ( ARGL_CONTEXT_SETTINGS_REF contextSettings )

◆ arglGetPixelZoom()

ARG_EXTERN int arglGetPixelZoom	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		float *	zoom
	)

Retrieve the current video image drawing scalefactor.

Parameters

zoom	The amount to scale the video image up or down. To draw the video image double size, use a zoom value of 2.0. To draw the video image half size use a zoom value of 0.5.

◆ arglGetRotate90()

ARG_EXTERN int arglGetRotate90 ( ARGL_CONTEXT_SETTINGS_REF contextSettings )

Find out whether ARGL is rotating all OpenGL drawing by 90 degrees.

On some OpenGL ES devices, it may be desirable to rotate all OpenGL drawing by 90 degrees in the window coordinate system, in order to swap the horizontal and vertical axes of the device. This may be a higher performance solution than manually swapping rows and columns of submitted data.

This function queries the current state of whether such a rotation is being performed by ARGL or not.

Parameters

contextSettings A reference to ARGL's settings for the current OpenGL context, as returned by arglSetupForCurrentContext() for this context.

Returns: TRUE if a 90 degree rotation is enabled, FALSE if it is disabled.

◆ arglGLCapabilityCheck()

ARG_EXTERN int arglGLCapabilityCheck	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		const uint16_t	minVersion,
		const unsigned char *	extension
	)

Checks for the presence of an OpenGL capability by version or extension.

Checks for the presence of an OpenGL capability by version or extension. The test returns true if EITHER the OpenGL driver's OpenGL implementation version meets or exceeds a minimum value (passed in in minVersion) OR if an OpenGL extension identifier passed in as a character string is non-NULL, and is found in the current driver's list of supported extensions.

Parameters

contextSettings	A reference to ARGL's settings for the current OpenGL context, as returned by arglSetupForCurrentContext() for this context.
minVersion	A binary-coded decimal (i.e. version 1.0 is represented as 0x0100) version number. If minVersion is zero, (i.e. there is no version of OpenGL with this extension in core) the version test will always fail, and the result will only be true if the extension string test passes.
extension	A string with an extension name to search the drivers extensions string for. E.g. "GL_EXT_texture". If NULL, the extension name test will always fail, and the result will only be true if the version number test passes.

Returns: TRUE If either of the tests passes, or FALSE if both fail.

Since: First available in ARToolKit 4.5.0.

Here is the call graph for this function:

◆ arglPixelBufferDataUploadBiPlanar()

ARG_EXTERN int arglPixelBufferDataUploadBiPlanar	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		ARUint8 *	bufDataPtr0,
		ARUint8 *	bufDataPtr1
	)

Upload a buffer of pixel data to an OpenGL texture for later use by arglDispImage().

ARGL provides the ability to perform distortion-compensated texturing of a camera video image into the OpenGL context, for the purpose of video-see through augmented reality. This function uploads the camera image data to an OpenGL texture, ready for later drawing using the function arglDispImage().

If a pointer to an ARParam structure has been passed in to function arglSetupDebugMode, then a check will be made whether debug mode is enabled, and if it is, then the buffer pointed to by this function will be ignored, and instead the debug image will be loaded for texturing.

Parameters

contextSettings	A reference to ARGL's settings for the current OpenGL context, as returned by arglSetupForCurrentContext() for this context.
bufDataPtr0	A pointer to the pixel buffer, which is a block of memory from which texture data will be read.

The layout of pixel data in the memory pointed to by bufDataPtr is assumed to be specified by the value of pixelFormat in the ARHandle submitted to arglSetupForCurrentContext(), but can be changed by calling arglPixelFormatSet() and/or arglPixelBufferSizeSet().

By default, the pixel buffer is assumed to be tightly packed, row-major array of dimensions equal to the calibrated camera image size (as passed in the fields arParam.xsize and arParam.ysize of the ARHandle submitted to arglSetupForCurrentContext().

The pixel data buffer submitted may, under some circumstances be allowed to be larger than the values of the calibrated camera image size (i.e. padded). See the discussion section of the documentation for function arglPixelBufferSizeSet() for more information.

This may only occur when the underlying OpenGL ES impementation does not support non-power-of-two textures. For the Apple iPhone family, this applies to the iPhone, the iPhone 3G, the iPod Touch 1st and 2nd Generation. The iPhone 3GS and the iPod Touch 3rd Generation support non-power-of-two textures, and thus padding of the pixel data buffer is not supported on these devices. If padding is desired, the desired buffer size must be submitted using arglPixelBufferSizeSet(). Check that the result from this function is TRUE before attempting to upload such a padded buffer.

Parameters

bufDataPtr1 NULL for single-plane (interleaved) textures, otherwise for bi-planar textures, a pointer to the pixel buffer, which is a block of memory from which texture data will be read for the second plane containing the CbCr components. This plane must have dimensions of half the size of plane 0, and 2-bytes per pixel (1 byte Cb, 1 byte Cr).

Returns: TRUE if the pixel buffer was successfully uploaded to OpenGL, FALSE otherwise.

◆ arglPixelBufferSizeGet()

ARG_EXTERN int arglPixelBufferSizeGet	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		int *	bufWidth,
		int *	bufHeight
	)

Query the size of pixel data buffers expected by arglPixelBufferDataUpload().

See function arglPixelBufferSizeSet() for a full discussion.

Parameters

contextSettings	A reference to ARGL's settings for the current OpenGL context, as returned by arglSetupForCurrentContext() for this context.
bufWidth	A pointer to int, which will be filled out with the buffer width, in pixels, or NULL if this value is not required.
bufHeight	A pointer to int, which will be filled out with the buffer height, in pixels, or NULL if this value is not required..

Returns: TRUE if the buffer size was successfully queried, FALSE otherwise.

◆ arglPixelBufferSizeSet()

ARG_EXTERN int arglPixelBufferSizeSet	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		int	bufWidth,
		int	bufHeight
	)

Specify a desired pixel buffer size larger than the camera image size.

By default, the pixel buffer accepted by function arglPixelBufferDataUpload() is assumed to be tightly packed, row-major array of dimensions equal to the calibrated camera image size (as passed in the fields arParam.xsize and arParam.ysize of the ARHandle submitted to arglSetupForCurrentContext().

The pixel data buffer submitted may, under some circumstances be allowed to be larger than the values of the calibrated camera image size (i.e. padded). This may only occur when the underlying OpenGL ES impementation does not support non-power-of-two textures. For the Apple iPhone family, this applies to the iPhone, the iPhone 3G, the iPod Touch 1st and 2nd Generation. The iPhone 3GS and the iPod Touch 3rd Generation support non-power-of-two textures, and thus padding of the pixel data buffer is not supported on these devices. If padding is desired, the desired buffer size must be submitted using this function. Check that the result from this function is TRUE before attempting to upload such a padded buffer.

Parameters

contextSettings	A reference to ARGL's settings for the current OpenGL context, as returned by arglSetupForCurrentContext() for this context.
bufWidth	The desired buffer width, in pixels.
bufHeight	The desired buffer height, in pixels.

Returns: TRUE if the desired buffer size is supported, FALSE otherwise.

◆ arglPixelFormatGet()

ARG_EXTERN int arglPixelFormatGet	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		AR_PIXEL_FORMAT *	format,
		int *	size
	)

Get the format of pixel data in which arglDispImage*() is expecting data to be passed.

This function enquires as to the current format of pixel data being expected by the arglDispImage*() functions. The default format is determined by the value passed to arglSetupForCurrentContext.

Parameters

contextSettings	A reference to ARGL's settings for the current OpenGL context, as returned by arglSetupForCurrentContext() for this context.
format	A symbolic constant for the pixel format in use. See AR_PIXEL_FORMAT in ar.h for a list of all possible formats.
size	The number of bytes of memory occupied per pixel, for the given format.

Returns: TRUE if the pixel format and size values were retreived, FALSE if an error occurred.

Since: First appeared in ARToolKit 2.71.

◆ arglPixelFormatSet()

ARG_EXTERN int arglPixelFormatSet	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		AR_PIXEL_FORMAT	format
	)

Set the format of pixel data which will be passed to arglDispImage*()

(description) In arg, the format of the pixels (i.e. the arrangement of components within each pixel) can be changed at runtime. Use this function to inform arg the format the pixels being passed to arglDispImage*() functions are in. This setting applies only to the context passed in parameter contextSettings. The default format is determined by the value passed to arglSetupForCurrentContext. Usually, image data is passed in directly from images generated by ARVideo, and so you should ensure that ARVideo is generating pixels of the same format.

Parameters

contextSettings	A reference to ARGL's settings for the current OpenGL context, as returned by arglSetupForCurrentContext() for this context.
format	A symbolic constant for the pixel format being set. See AR_PIXEL_FORMAT in ar.h for a list of all possible formats.

Returns: TRUE if the pixel format value was set, FALSE if an error occurred.

Since: First appeared in ARToolKit 2.71.

◆ arglSetFlipH()

ARG_EXTERN void arglSetFlipH	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		int	flipH
	)

◆ arglSetFlipV()

ARG_EXTERN void arglSetFlipV	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		int	flipV
	)

◆ arglSetPixelZoom()

ARG_EXTERN int arglSetPixelZoom	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		float	zoom
	)

Set the current video image drawing scalefactor.

Parameters

zoom	The amount to scale the video image up or down. To draw the video image double size, use a zoom value of 2.0. To draw the video image half size use a zoom value of 0.5.

◆ arglSetRotate90()

ARG_EXTERN void arglSetRotate90	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		int	rotate90
	)

Set or unset a 90 degree rotation in all OpenGL drawing performed by ARGL.

On some OpenGL ES devices, it may be desirable to rotate all OpenGL drawing by 90 degrees in the window coordinate system, in order to swap the horizontal and vertical axes of the device. This may be a higher performance solution than manually swapping rows and columns of submitted data.

This function enables or disables such an axis swap in ARGL with very little performance cost, by introducing a 90-degree rotation into the OpenGL projection matrix.

By default, 90 degree rotation is DISABLED.

Parameters

contextSettings	A reference to ARGL's settings for the current OpenGL. context, as returned by arglSetupForCurrentContext() for this context.
rotate90	Set to TRUE or 1 to enable 90 degree rotation, FALSE to disable.

◆ arglSetupDebugMode()

ARG_EXTERN int arglSetupDebugMode	(	ARGL_CONTEXT_SETTINGS_REF	contextSettings,
		ARHandle *	arHandle
	)

Provide an ARHandle structure from which to extract information about debug mode.

This provides support for the debug mode in libAR. If arg has been compiled with debug mode support, the passed in ARHandle is used as the source of whether debug mode is enabled or disabled. If enabled, the binarized debug image will be drawn instead of the input image.

Parameters

arHandle A pointer to an ARHandle structure from which to extract debug info, or NULL if debug functionality is not required. Default is NULL.

Returns: TRUE if the mode was set, FALSE if an error occurred.

Since: First appeared in ARToolKit 4.5.12.

◆ arglSetupForCurrentContext()

ARG_EXTERN ARGL_CONTEXT_SETTINGS_REF arglSetupForCurrentContext	(	const ARParam *	cparam,
		AR_PIXEL_FORMAT	pixelFormat
	)

Initialise the arg library for the current OpenGL context.

This function performs required setup of the arg library for the current OpenGL context and must be called before any other argl*() functions are called for this context.

An OpenGL context holds all of the state of the OpenGL machine, including textures and display lists etc. There will usually be one OpenGL context for each window displaying OpenGL content.

Other argl*() functions whose operation depends on OpenGL state will require an ARGL_CONTEXT_SETTINGS_REF. This is just so that they can keep track of per-context variables.

You should call arglCleanup() passing in the ARGL_CONTEXT_SETTINGS_REF when you have finished with the library for this context.

Parameters

cparam Pointer to a set of ARToolKit camera parameters for the current video source. The size of the source image is taken from the fields xsize and ysize of the ARParam structure pointed to. Also, the field dist_factor of the ARParam structure pointed to will be taken as the amount to un-warp the supplied image.

Prior to ARToolKit v5.1.5, the ARParam structure pointed to had to remain valid in memory for the duration of the ARGL_CONTEXT_SETTINGS_REF's usage. As of ARToolKit v5.1.5, the ARParam structure pointed to is copied, and no longer need be maintained.

Parameters

pixelFormat The type and format of pixels of the images to be drawn by the arg library. This value can be changed later by using arglPixelFormatSet()

Returns: An ARGL_CONTEXT_SETTINGS_REF. See the documentation for this type for more info.

Since: First appeared in ARToolKit 2.68.
