3D-Engine-Python

My take on Coder Space's Python 3D Engine Series.

Differences

• Code is from myself following Coder Space's video tutorial
• Included documentation on how the program's modules work

Modules

Module	Description
camera.py	Camera data
light.py	Sunlight data
main.py	Main application
mesh.py	Mesh material information
model.py	Models' rendering information
scene_renderer.py	Scene rendering information
scene.py	Accumulated scene objects
shader_program.py	Mesh shaders
texture.py	Raw texture data
vao.py	Vertex Array Objects
vbo.py	Vertex Buffer Objects

Rendering Process

Step	Code	Description	Generated/Processed Data
0	def __init__()	Create OpenGL information	OpenGL version • Window information
1	self.light = Light()	Create sunlight data	Color • Orientation • Matrices
2	self.camera = Camera(self)	Create camera data	Orientation • Matrices
3	self.mesh = Mesh(self)	Create all mesh data	VBOs • Shaders • VAOs • Textures
4	self.scene = Scene(self)	Accumulate all mesh instances in a scene	uniform data for each meshes' instance
5	self.scene_renderer = SceneRenderer(self)	Render the accumulated mesh instances and post-processing

Notes

• Use literals to initialize data, such as []

  Initialization (list()) changes how data's stored.

• For each mesh, create one shared set of VBO, VAO, and shader programs

  We change each mesh instance's geometric properties through uniform attributes.
