Many of you know of Brix Builder, a project I've been working on for a few months now. It started as a simple wireframing perspective engine, but has evolved into something that can do wireframe and hidden line, blank-face and vertex-shading, rotation, and scaling, all in a 4KB engine. I have that besides Brix Builder, I will be releasing it separately as the HPS3D Engine: Hidden Line / Wireframe Perspective Shading 3D Engine for z80 Calculation Devices. It is capable of taking a list of polygons and a settings list and rendering into a fully dithered 3D perspective hidden-line image; I will post some screenies as soon as I can get my GraphLink working.
