Package Requirement

pip install -r requirements-dev.txt

---

Development Setup

pip install -r requirements-dev.txt
pre-commit install

Bugs (unsolved issues)

• The z sorting of triangles still has some noticeable issues
• still need some optimization to run faster ( maybe using numpy matrices can help a little bit)
• issues with translate matrix , gonna fix it later still trying a couple of things

---

Support .obj files although the z-sorting isn't working properly

Directional lighting

light = Light(position)
# to disable the light in the scene you can set the light = None
light = None

Controls

Might work on a much better controls later but for now to move around the scene you can use "WASD" and "Arrows". The controls are weird , I'm gonna try to improve them.

Parameters

---

Display normals:

ShowNormals = True
# you can set the normal lines length in the world.py file

---

It still has a couple of issues when it comes to the boundary clipping , since it's only clip the faces that are in front of the camera.

---

Wireframe Mode

wireframe = True

---

Display Point Vertices

vertices = True

# red: x axis
