virtual bool osg::TexMat::isTextureAttribute | ( | ) | const [inline, virtual] |
Return true if StateAttribute is a type which controls texturing and needs to be issued w.r.t to specific texture unit.
Reimplemented from osg::StateAttribute.
virtual int osg::TexMat::compare | ( | const StateAttribute & | sa | ) | const [inline, virtual] |
Return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.
Implements osg::StateAttribute.

Set the texture matrix

Get the texture matrix

Get the const texture matrix
void osg::TexMat::setScaleByTextureRectangleSize | ( | bool | flag | ) | [inline] |
Switch on/off the post scaling of the TexMat matrix by the size of the last applied texture rectangle. Use a TexMat alongside a TextureRectangle with this scaling applied allows one to treat a TextureRectnagles texture coordinate range as if it were the usual non dimensional 0.0 to 1.0 range. Note, the TexMat matrix itself is not modified by the post scaling, its purely an operation passed to OpenGL to do the post scaling once the the TexMat matrix has been loaded.
bool osg::TexMat::getScaleByTextureRectangleSize | ( | ) | const [inline] |
Get whether the post scaling of the TexMat matrix, by the size of the last applied texture rectangle, is switched on/off.
virtual void osg::TexMat::apply | ( | State & | state | ) | const [virtual] |
Apply texture matrix to OpenGL state.
Reimplemented from osg::StateAttribute.
