Description

Pico GPU is a small educational GPU environment hosted for learning and experimenting with shaders under a strict memory budget.

It targets 640x480 at 60 FPS with 24-bit depth and 8-bit stencil, only 300 KB of GPU memory for textures, buffers, code, and shaders, plus four mono 32-bit audio channels at 48 kHz synthesized with GPU shaders. Feature support includes vertex and fragment buffers, blending, culling, depth, stencil, color mask, clipping, render targets, instancing, and matrix, vector, and quaternion math helpers.

It is for beginners and hobbyists who want constrained 3D demos or tiny games without a full engine. Prior shader basics help, but the product is aimed at playful learning rather than production shipping.

The site offers documentation, download, community, and about sections. Apps can be saved and loaded as 640x480 PNG screenshots that embed project data for sharing.

It is useful as a sandbox for small shader demos where hard memory limits force clear choices about what to upload and draw.
