What it does
The first visual compositor for real-time GPU effects. Layer shaders, 3D, text, and animations in one editor. Build by visually by hand or tell AI what to build. It works directly in the compositor, not a code sandbox. 50+ presets. 15 3D primitives with PBR materials. Custom GLSL. Hover, scroll, click, and appear events per layer. With Native AI built in and an MCP server with 22 tools. AI gets the same controls you do. Exports a single HTML file. No SDK. No vendor lock-in.
Compose shaders, text, and 3D into interactive scenes. Export an embed that works in any site. No packages, no build step, no SDK in your project.
Shaders, 3D, and text in one compositor. Export a single embed tag that works on any site. No packages, no build step, no SDK in your project. Gradients, noise, plasma, caustics, chrome, topographic contours, and more. Start from a preset, import your own SVG, or write custom GLSL. Add text, shapes, and 3D alongside your shaders, then animate them. Hover, click, scroll, and viewport triggers. Chain animations across layers and export the whole scene as one embed. 15 font families, custom font uploads, shapes, and colors. Position anything freely on the canvas alongside shader layers. Mouse follow, repel, distort, pulse, and orbit. Click toggles, hover animations, scroll-driven motion, and…from refract.build

GPT-2 implemented using graphics shaders2025 · github.com · ▲228Back in the old days, people used to do general-purpose GPU programming by using shaders like GLSL. This is what inspired NVIDIA (and other companies) to eventually create CUDA (and friends). This is an implementation of GPT-2 using WebGL and shaders. Enjoy!

MCP server for Blender that builds 3D scenes via natural language2025 · blender-mcp-psi.vercel.app · ▲151Hi HN! I built a custom MCP (Model Context Protocol) server that connects Blender to LLMs like ChatGPT, Claude, and any other llm supporting tool calling and mcps, enabling the AI to understand and control 3D scenes using natural language. You can describe an entire environment like: > “Create a small village with 5 huts arranged around a central bonfire, add a river flowing on the left, place a wooden bridge across it, and scatter trees randomly.” And the system parses that, reasons about the scene, and builds it inside Blender — no manual modeling or scripting needed. What it can do: -…
