Open-source alternatives to Image Editor Effects

⚔️ CrossShader

SHADERed is a cross-platform shader development environment and debugger used for authoring vertex, pixel, and compute shaders. It functions as an integrated editor for writing and compiling shader code while providing live visual previews and the ability to configure render pipeline states. The tool features a GLSL shader debugger that enables line-by-line execution with breakpoints and variable watches to resolve visual logic errors. It includes a shader asset manager for importing 3D models and textures as data inputs and supports an extensible plugin system to integrate new languages and

Khronos-reference front end for GLSL/ESSL, partial front end for HLSL, and a SPIR-V generator.

SPIRV-Cross is a practical tool and library for performing reflection on SPIR-V and disassembling SPIR-V back to high level languages.

This is the source code for How to render outlines in WebGL & Better outline rendering using surface IDs with WebGL implemented in ThreeJS and PlayCanvas. This renders outlines with a post-process shader that takes the depth buffer and a surface normal buffer as inputs, followed by an FXAA pass.
