Subject: | ALLEGRO: get_camera_matrix normals |
Message-ID: | <19970402010432.AAA7397@hometown> |
In the docs for 'get_camera_matrix' it mentions that xup, yup, and zup need not be normal, does this also mean that they can be used as a point the camera is 'looking' at? Also, what is the performance hit on using floats for everything (in 3d) on a Pentium. I heard that in most cases it was actually faster than fixed, is this true? Thanks Jeff Bachtel
