How to use my own defined camera_like() function instead of camera()?

alwayzmile

I've got a programming assignment to simulate how 3d viewing works from scratch. I want to use my own defined function for projection instead of using camera() function. Is it possible? If possible, how to do that?

Thank you.

Dunno... Maybe you should take a look at camera()'s implementation by yourself:

Implicitly you'll always have the processing camera.

But you can calculate your own camera, building your own cameraClass with its position, where it is looking at (and maybe rotation and other stuff)

Look at wikipedia viewport / 3D graphics etc. or google
