Overview

@luma.gl/shadertools provides textual shader assembly utilities and the shader descriptors used by luma.gl engine classes. It does not compile shaders or call WebGL or WebGPU APIs.

Use the Shader-Level Programming guide for authoring choices. Use this section for exact shadertools descriptors, assembler methods, WGSL assembly behavior, and built-in module catalogs.

Reference Pages

• ShaderModule describes reusable shader source, uniform descriptors, bindings, dependencies, and injections.
• ShaderPass describes shader modules that can run through the engine pass renderer.
• ShaderPlugin
• ShaderAssembler
• ShaderInfo

For the uniform descriptor syntax used by shader modules, see Core Shader Types. For the engine-side module prop and binding bridge, see ShaderInputs.
