project_2d: Project 3D coordinates to 2D

In bobverity/bobfunctions2: Bob's utility functions

Project 3D coordinates to 2D

Description

Use a projection matrix to transform 3D world coordinates to 2D coordinates - for example representing a camera viewing a 3D scene. See get_projection() for how to obtain a projection mtarix. This function is equivalent to the trans3d() function, but also stores depth information relative to the camera.

Usage

project_2d(x, y, z, proj_mat)

Arguments

x, y, z	world coordinates.
proj_mat	4*4 projection matrix, as returned from get_projection().
