Welcome to Render_in_C! This project is a basic 3D software renderer written in C, designed to be lightweight, educational, and a solid foundation for learning computer graphics from scratch. Here, you'll explore and experiment with core rendering techniques like rasterization, shading, geometric primitives, and simple lighting effects—all in pure C.
- Software rendering: No OpenGL/DirectX—everything is implemented from scratch in C.
- Triangle rasterization and basic geometric primitives.
- 3D transformations: World, view, and projection matrices.
- Texturing and color: Switch between wireframe, color, and textured rendering modes.
- Windows GUI using GDI for framebuffer display and input.
- Modular, educational code: Perfect for learning the fundamentals of 3D graphics.
main.c: Entry point, main loop, and rendering logic.geometric_calculations.*: Vertex operations, interpolation, and geometry.math.*: Linear algebra, matrices, and vectors.rendering.*: Rasterization pipeline and triangle rendering.rendering_device.*: Framebuffer, z-buffer, and texture management.transform.*: 3D transformations and projection.win32_graphics.*: Windows windowing and event handling.
- Operating System: Windows (uses GDI for window and framebuffer)
- Compiler: GCC (MinGW recommended) or MSVC
- Libraries:
gdi32(included with Windows)
Compile the project with (GCC/MinGW):
gcc -O3 main.c geometric_calculations.c math.c rendering.c rendering_device.c transform.c win32_graphics.c -o GOATY_GOAT_RENDER.exe -lgdi32- Run the binary
GOATY_GOAT_RENDER.exe. - Controls:
ESC: Exit- Left/Right arrows: Rotate the cube
- Up/Down arrows: Move camera forward/backward
Space: Switch rendering mode (texture, color, wireframe)
- The renderer implements a basic 3D pipeline: vertex transformation, projection, clipping, rasterization, and shading.
- Framebuffer and z-buffer are managed manually in memory.
- The 3D cube is rendered using triangles, and you can toggle between different visualization modes.
- All code is modular and educational—perfect for learning or tinkering.
- Deep learning: Understand how 3D graphics work under the hood, without the magic of external APIs.
- Foundation for advanced projects: Expand it with lighting, advanced textures, OBJ models, and more.
- Inspiration: Ideal for students, enthusiasts, and makers!
