Hello all, I'm a new to algebra, but am very interested in learning.

So I was wondering if anyone can provide a link to a tutorial that

would explain all things about perspective transformation matrix.

I have been learning all the rotation and scaling and translations.

but am not able to write my own functions for perspective transformations.

I know I can use GL_PROJECTION_MATRIX, but I am more interested in

the actual implementation of the whole matrix staff. For example if I want

to

write some program with out using OpenGL just to solidify my skills in

algebra and staff.

Thank you for you time.

Daniel.
