Python_Rasterizer

Description

This is an implementation of a Software Rasterizer written in Python.

Dependencies

PyGame
Python 3.x is recommended.

Notice

This is a pure Python 3.x code, and will be very slow on CPython interpreter.

For speed boost, kindly use PyPy version.

I've also implemented it in Cython, check that branch Cython_Ver. Cython code is much more verbose compared Pure Python due to Types, but in return you get blazing fast speed of C (Native C will almost always be faster)

Building

Clone this Repository
Simply run main.py file
Changes in the scene can be made by editing scenefile.py or scenefile2.py, whichever is imported in main.py

Features

Perspective and Orthographic Projection
Rotation, Translation and Scale
Real-time Preview using PyGame
Diffuse and Specular Shading
Directional and Point Lighting
Real-time Profiling
OBJ import support (only triangluar geometry is supported for now)

ChangeLog

Sept 28,2021

* Initial Commit (see Features)

Editing Scenes

Kindly Read RenderLib.py file and if you understand a little bit of it, Scenes are defined by using a Scene object which contains all the data of scene.

I know this is not enough to explain but I'll be writing doc-strings in each every class and functions.. And in future, I maybe create a wiki or documentation for using this project

Contributions

If you like this Project, and want to improve something in it, or just want to reimplement this from your perspective (any class/function/algorithm or whole project), feel free to do.. It will be very appreciated!

If you find any bug or issues, please report it in the issue section.

And we are going to take over the VFX industry with this 🙂, so support
