OPENGL gluPerspective implementation

QUESTION

OPENGL gluPerspective implementation

Asked 2022-Apr-09 at 19:57

I have a problem when I implement my own gluPerspective matrix transformation. It doesn't display anything. But when I comment out my perspective implementation, using the api, it seems like my Lookat function can work. I'm not sure where is the problem? Here is my reference for my matrix transformation: http://www.3dcpptutorials.sk/index.php?id=2

The calculation of the projection matrix and view matrix is wrong. OpenGL matrices are column major order matrices. Therefor you need to transpose the matrices. For the mathematical functions, the unit of angle is radians. However, there are some other issues with your projection matrix. See OpenGL Projection Matrix. Correct matrices looks like this:

As far as I can tell Quake 3, Star Trek Elite Force I & II, Half Life 1, Unreal, Unreal Tournament 99, Heavy Metal: F.A.K.K.², Serious Sam - The First & Second Encounter and Warcraft III work pretty well for the most part. Homeworld, Enclave and Doom 3 work okay. Blade Of Darkness isn't really playable as I haven't implemented display lists. I haven't tried other titles so far.
