reOpenGL — Lightweight OpenGL Abstraction in C.

reOpenGL is a lightweight OpenGL utility and abstraction layer written in pure C.

Features

• Easy window creation with GLFW
• Texture loading using stb_image.h
• 3D Camera system (FPS-style)
• Mesh abstraction with VAO/VBO support
• Framebuffer support (offscreen rendering)
• Input handling (keyboard + mouse)
• Shader compilation & linking with GLSL file loading
• Projection & View matrix utilities via cglm

Requirements

• C89/C99/C11
• OpenGL 3.3+
• GLFW
• GLEW
• stb_image (included as stb_img.h)
• [Deprecated] LAmath.h (Custom or minimal math library for Vec3f, Mat4f, etc.) : author (gWall)
• Instead of using LAmath.h , we use cglm now! until we fix "LAmath.h"

important flags when you compile using gcc:
NOTE : -lm : for math library needed for cglm. -lc : links the C standard library.

gcc -o test test.c decl_file.c -lglfw3 -lopengl32 -lGLEW32 -lm -lc
