Detailed Description

Todo:

Documentation is rudimentary.

This module provides a few classes that allow building simple scenes in OpenGL, create textures, display images as textures in OpenGL, and so on.

Function Documentation

getGLBuffer()

bool goGL::getGLBuffer

(

goSignal3D< void > &

ret

)

Get the current OpenGL buffer into a goSignal3D<void>.

Parameters

ret

The image taken from the OpenGL buffer. It will have the data type that ret had before the call, and the format will depend on its channel count: If it has 1 channel, GL_LUMINANCE will be read, if 3, GL_RGB will be read, and if 4 channels GL_RGBA will be read. Any othe channel count will result in an error (return false).

Returns

True if successful, false otherwise.

viewSphere()

bool goGL::viewSphere	(	goFloat	phi,
		goFloat	theta,
		goFloat	radius,
		goVectorf *	positionRet = 0,
		goVectorf *	upRet = 0
	)

Set OpenGL camera on view sphere, looking at the origin.

Parameters

phi	in [-pi,pi]
theta	in [0,2*pi]
radius
positionRet	3D position, return value
upRet	3D up-vector, return value

Returns

True if successful, false otherwise.
