This repo consists of a Rust implementation of the tinyrenderer walkthrough by professor Dmitry V. Sokolov.
- image 0.24.5: Image loading and manipulation
- piston_window 1.127.0: Window to display rendered frames
- obj-rs 0.6: To retrieve information from .obj files
- nalgebra 0.31.4: For vector and matrix calculations
To run, just clone any of the branches and do:
cargo run --release <assets directory>
where <assets directory> is the directory in which the corresponding assets of the model are. For example, to run Lesson 7 you must do:
cargo run --release assets/diablo3_pose
At the moment, if you want to use other models/textures, you would have to modify the respective assets names in main.
Write to an image buffer and render it in a window.
Branch: Lesson_0
Preview:
Implement Bressenham's line algorithm. Then, use it to draw the wireframe model of a mesh.
Branch: Lesson_1
Preview:
Implement triangle filling using both line sweeping algorithm and barycentric coordinates algorithm. Then implement a basic directional lighting model, computing the lighting of each triangle face using its normals.
Branch: Lesson_2
Preview:
Implement Z-buffer algorithm for back-face culling. Then, apply textures to the mesh.
Branch: Lesson_3
Preview:
Implement perspective projection.
Branch: Lesson_4
Preview:
Implement Gouraud shading. Then, implement model view, projection, and viewport transformation matrices. Lastly, apply several transformations to the model through matrices transformation chaining.
Branch: Lesson_5
Preview:
Structure code into shaders form. Then, implement texture-based normal mapping for the model, using both global coordinate system normal mapping and Darboux frame normal mapping. Lastly, improve lighting by composing the lighting of the model using ambient, diffuse, and specular lighting (Phong shading).
