Online HLSL Editor

The tool enables in-browser editing of HLSL code with immediate, serverless feedback. It supports vertex and pixel shader entry points, common shader models, and in-editor macros. Users write code, select shader model and entry point, and trigger compilation to see a live output preview on a canvas that reflects the shader's color and lighting results. The in-browser pipeline provides syntax highlighting, error localization, and diagnostic messages to accelerate debugging. Conceptually, the system parses HLSL syntax, performs lightweight semantic checks, and passes valid code to a WebGL/WebGPU-based renderer that emulates essential HLSL behavior for testing, while exposing diagnostic data such as line and column numbers. This combination enables rapid experimentation, education, and reproducible snippets for collaboration. Unique value lies in complete client-side operation, shader-model awareness, and integrated live preview without local toolchains or file I/O. Core features include editor with syntax highlighting, entry point and shader model selection, define macros, and a browser preview that reflects fragment shader outputs in real time. Use cases range from learning shader programming to debugging complex shading techniques in DX11/DX12 contexts. Optional capabilities include code completion, snippet libraries, and export/import of shader sources for teamwork. The tool is designed for developers, researchers, and students seeking fast feedback cycles, portable experiments, and shareable shader examples.
