Detailed Description

Projects 3D models into a GL context given a camera projection matrix.

vgui_camera is a utility class which allows 3D models to projected into a GL context given a known camera projection matrix. Note comments in code about clipping planes which is really rather important if you care about such things. Use the class in conjunction with a vgui_load (if you dare), or a vgui_mult to change the GL_PROJECTION_MATRIX appropriately.

Member Function Documentation

vnl_matrix_fixed< double, 3, 4 > vgui_camera::get_glprojmatrix	(	const int	imagesizex = 720,
		const int	imagesizey = 576
	)		const

Plug this matrix into a vgui_loader_tableau.

Note: this will return a GL_PROJECTION_MATRIX with the assumption that you have a Euclidean reconstruction. The result is that the front and back clipping planes will be PARALLEL (note: not projective frame!) to the image plane.
