GraphicsEngine

A windows console 3D graphics engine written in C#.

⚠️ This is a very rudimentary learning project! See inspirations below on much better implementations.

This is a learning project regarding creating the foundations of a 3D graphics engine.

Much inspiration was taken from these guys:

• https://github.com/interl0per/Console-Graphics
• https://github.com/Victormeriqui/Console3D

(Though for the vast majority of things, I am writing entirely from scratch for complete learning.)

Customized wavefront obj loading code I am currently using: https://github.com/ChrisJansson/ObjLoader

Features:

• Loading of 3D wavefront object models, converting to mesh representation. Models with faces containing more than 3 vertices is supported.
• Lazy rasterizer: A sequence of drawing actions are cached and only executed when final image rasterization is executed.
• Ability to draw (rasterize) points, lines, triangles, polygons, vertical & horizontal strings, axes, and meshes to buffer.
• Mesh center vertices and bounding box can also be drawn.
• Meshes can be rasterized as wired polygons, vertices, or as solids (tad bit buggy).
• Ability to transform rasterized objects: scaling, translation, and rotations along every axis.
• 16 bit polychromatic rendering baby! Still a bit to do for the API for the colors and such.
• Rudimentary polygon hiding algo (zbuffer). (tad bit buggy)

To do:

• Update transformation so objects are scaled and rotated around the objects center, even for object models not centered around (0, 0, 0).
• Implement a camera (perspective projection).
• Lighting & shadows.
• Some Kernel32 Console Abstractions (coloring, etc).
• Create an asteroids game demo using the engine.
