A textured moon sphere with bump mapping and soft lighting. (Scene: moon.rt)
Sea texture demonstration (sea.rt)
Paraboloids, boxes, and spheres in a sandy environment with textures. (Scene: desert.rt)
- Language: Pure C, Norm-compliant, no leaks, full error handling.
- Graphics: MLX42, minimal graphic library from codam.
- Math Libraries: Custom vector algebra, quaternion operations, and geometric utilities.
- Concurrency: POSIX threads to make rendering fly on multi-core CPUs.
- Quaternion Rotations: Smooth transformations using custom quaternion math.
- Texture Mapping: Bilinear-filtered PNG support with normal mapping for surface details.
- Anti-Aliasing & DoF: Random sampling for camera effects and noise reduction.
- Real-Time Editing: Mouse-based object manipulation with intuitive controls.
- Multi-Threading: Scalable parallel processing with job queues and synchronization.
- Movement: W/A/S/D to move forward/left/back/right, Space/Shift for up/down.
- Object Selection: Left-click on an object to select it.
- Editing Modes: Hold Z + click to translate, X + click to rotate, C + click to scale.
- Quit: ESC to exit.
- Dump Scene: F5 to save the current scene to a file.
Scenes are defined in .rt files with the following elements:
- Ambient Light:
A ratio R,G,B [secondary_R,G,B] [texture] - Camera:
C pos_x,y,z dir_x,y,z fov [focus_depth] [aperture] - Light:
L pos_x,y,z brightness R,G,B [radius] - Sphere:
sp pos_x,y,z radius R,G,B [rough] [metallic] [texture] [bump] - Plane:
pl pos_x,y,z normal_x,y,z R,G,B [rough] [metallic] [texture] [bump] - Cylinder:
cy pos_x,y,z normal_x,y,z radius height R,G,B [rough] [metallic] [texture] [bump] - Paraboloid:
pa pos_x,y,z normal_x,y,z radius height R,G,B [rough] [metallic] [texture] [bump] - Box:
bx pos_x,y,z normal_x,y,z size_x,y,z R,G,B [rough] [metallic] [texture] [bump]
All values are floats, colors in 0-255 range, positions/normals in world coordinates.

-
Build it:
make
-
Run a scene:
./miniRT maps/std.rt
-
Play around: Load different .rt files from
maps/and edit scenes live!
- oliynykmax: Handled all the parsing, validation, and file stuff.
- datagore: Focused on the rendering core, math libs, and making it fast.
