I’m trying to following some OpenGL tutorials to learn the matrix transforms

is using. I see FPC has a matrix class but it doesn’t include all the helpers
in GLM like rotation, transform, perspective transforms
(https://open.gl/transformations). If I knew enough I think I could just build
these myself but I’ll likely introduce a bunch of errors at first.
Has anyone converted these to Pascal before or having some similar I could look
at?

I use my own vector/matrix library VectorUtils3, which is written in
plain C (thereby FPC friendly), and included in the common code of my
OpenGL demo library:
http://computer-graphics.se/demopage/
Actually, there is also an FPC version of VectorUtils, FPC interfaces to
most of my common code, and even a bunch of demos that I made FPC for.
(Modern OpenGL, not old-style code, no immediate mode.) I never uploaded
them anywhere, since there didn't seem to be much interest, but if
someone wants them, no problem.
