Shader Types Guide

luma.gl uses portable shader type descriptors across @luma.gl/core, @luma.gl/engine, and @luma.gl/shadertools.

The canonical descriptor reference now lives in Core Shader Types.

Use that page for:

• primitive uniform descriptors like 'f32', 'vec3<f32>', and 'mat4x4<f32>'
• composite uniform descriptors for structs and fixed-size arrays
• UniformTypes<T> validation rules
• nested ShaderInputs updates and uniform-buffer packing behavior
• canonical array descriptors for uniform buffers

Where Shader Types Show Up

• ShaderModule.uniformTypes declares shader-facing layouts
• ShaderInputs preserves nested app-facing values
• UniformStore and ShaderBlockLayout flatten and pack those values for upload

The nested update is merged by schema before being packed into the backing uniform buffer.
