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
