void GpuHelper::forceMatrixTarget ( GLenum matrixTarget ) [inline]

Make the matrix matrixTarget the current OpenGL matrix target. Call this function before loadMatrix() or multMatrix() if you cannot guarantee that glMatrixMode() has never been called after the last loadMatrix() or multMatrix() calls.

Todo:: provides a debug mode checking the sanity of the cached matrix mode.

Definition at line 78 of file gpuhelper.h.

template<typename Scalar , int _Flags>

void GpuHelper::loadMatrix	(	const Eigen::Matrix< Scalar, 4, 4, _Flags, 4, 4 > &	mat,
		GLenum	matrixTarget
	)

Load the matrix mat to the OpenGL matrix matrixTarget. Essentially, this helper function automatically calls glMatrixMode(matrixTarget) if required and does a proper call to the right glLoadMatrix*() or glLoadIdentity() function according to the scalar type and storage order.

Warning:: glMatrixMode() must never be called directly. If your're unsure, use forceMatrixMode().

template<typename Scalar , int _Flags>

void GpuHelper::multMatrix	(	const Matrix< Scalar, 4, 4, _Flags, 4, 4 > &	mat,
		GLenum	matrixTarget
	)

Multiply the OpenGL matrix matrixTarget by the matrix mat. Essentially, this helper function automatically calls glMatrixMode(matrixTarget) if required and does a proper call to the right glMultMatrix*() function according to the scalar type and storage order.

Warning:: glMatrixMode() must never be called directly. If your're unsure, use forceMatrixMode().
