Sharing a fun visualization of what the early shader-based rasterizer on our custom #gpu looks like in-simulator. Threads walk over the bounding box area of a triangle. Next optimization here is: on a row, if you have seen some pixels and now you don't, skip to next row. #fpga #emulator

More progress on #webgpu #dreamcast GPU simulation. This is opaque list-only rendering with just base colors (no texturing). You can see how Soul Calibur would multiply these base colors with albedo texture to produce per-vertex lighting. Progress!

#webgpu -based simulation of the #dreamcast PowerVR GPU is making progress slowly. The entire ISP/TSP processing of lists is done via compute shader. The shader walks over TA-generated data structures in dreamcast VRAM. Stutters are understood and will be fixed. PROGRESS!!

Sharing here the first on-FPGA triangle we rendered. This was some time ago, and we have performed significant pipelining optimizations to the design at this point. Rasterization can be easily parallelized. It's based on a moving grid of rasterizers based on Pineda-style edge-equations.
