matrix_build_projection_perspective

This function builds a perspective projection matrix matrix based on the dimensions of the near plane, using the specified parameters listed below.

Syntax:

matrix_build_projection_perspective(width, height, znear, zfar);

Returns:

Matrix index

Example:

var projmat = matrix_build_projection_perspective(640, 480, 1.0, 32000.0);
camera_set_proj_mat(view_camera[0], projmat);

The above code creates a perspective projection and then uses the matrix returned to set the camera assigned to view port[0].
