threejs-exposure-color-grading

Implement exposure and color grading in Three.js WebGPU by building a specialized TSL path. This provides accurate luminance metering, GPU-resident EV adaptation, and explicit tone mapping with lut3D grading for real-time graphics.

Available luminance metering options for Three.js TSL shaders include fixed, sampled, reduced, and histogram metering. These options enable precise exposure control within GPU-resident EV adaptation workflows.

No, you cannot use this exposure grading path without WebGPU support. Implementing the TSL-based luminance metering and EV adaptation requires a Three.js environment explicitly configured with WebGPU capabilities.

GPU-resident EV adaptation works for real-time graphics exposure by calculating luminance directly on the GPU. This enables accurate, frame-by-frame exposure control and explicit tone-map ownership without CPU readbacks.

The best way to apply lut3D color grading in Three.js is using a domain-correct TSL implementation. This approach pairs explicit tone-map output ownership with WebGPU acceleration for accurate real-time color correction.

You need TSL for Three.js real-time graphics exposure control because it provides the shader language required to build specialized WebGPU paths. TSL enables accurate luminance metering and GPU-resident EV adaptation.
