Hello guys! Few months ago i'm started to create simple 3D engine on the pure C and OpenGL 1.4. Here is the result of my work.
And from here you can download and test the demo: https://www.dropbox.com/s/5gmd8i241drxyzq/OGL_public.rar?dl=0
Controls in demo: [WSAD] - movement, [Space] - jump, [C] - crouch, [Q][E] - turn on\off lights.
Lightmap generation time is about 3 minutes, so be patient.
PS. Sorry for my english.
