Hello,
I'm trying to use projective texture and the dimensions of the texture
I'm using are not a power of 2.
I used the osgDepthShadow example as a starting point and modified it
to use osg::TextureRectangle instead of osg::Texture2D.
Since texture rectangle uses texture coordinates [0,width] and
[0,height] instead of [0,1] and [0,1], I modified the osg::Matrix MVPT
supplied to TexGen->setPlanesFromMatrix so that it could generate the
proper texture coordinates.
For a 640x480 texture:
osg::Matrix MVPT = _cameraNode->getViewMatrix() *
_cameraNode->getProjectionMatrix() *
osg::Matrix::translate(1.0,1.0,1.0) *
osg::Matrix::scale(320.0,240.0,0.5);
This has not worked. :(
Has anyone done it before? Any advice is appreciated.
Thanks in advance,
Enylton.
