0.1.2

Added

• WebGPU displacement supports displacementBias (default 0) for signed height offsets in mesh-local units, including conversion from Three.js materials.

Changed

• displacementStepSize now defaults to 0, automatically using 1/32 of the absolute displacement height. Set 0.01 explicitly to retain the previous fixed step; smaller steps capture finer detail at a higher rendering cost.
• Converting a Three.js material without a displacement map now uses MuTracer's default height of 0.1 instead of Three.js's inactive default of 1. Other configured heights are preserved.

Fixed

• Editing displacement maps, image sources or height settings updates the rendered surface correctly, including meshes that share geometry.
• Displacement remains consistent when object transforms scale the mesh, including small displacement heights.
• WebGL 2 renders the original surface correctly when displacement settings are present; displacement requires WebGPU.
• Clicking or holding a stationary view with Three.js controls preserves accumulated samples and completed renders.

0.1.1

Changed

• Interactive previews adapt resolution to tracing, denoising and display latency.

Fixed

• Denoised previews remain responsive and finish during continuous interaction, with stable transitions to the final render.
• Three.js camera controls settle reliably and account for elapsed time when damping.
• Animation and incremental geometry updates retain prepared BVHs.
• Shadow catcher denoising receives auxiliary albedo and normal guides on both WebGPU and WebGL 2, reducing color artifacts.

0.1.0

Added

• Progressive browser path tracing on WebGPU with a WebGL 2 fallback.
• Area, sphere, spot/IES, directional and environment lights with multiple importance sampling.
• OpenPBR 1.1 materials including coat, fuzz, thin film, transmission, subsurface and emission.
• Static BLAS construction in a Worker with the TypeScript binned SAH builder or optional TinyBVH WebAssembly, selectable bvhLayout, and instance-transform refits.
• OIDN denoising for final images and converging previews; bundled standard/small networks and an independent complete weights package.
• Three.js scene conversion and retained synchronization with THREESceneSync.
• Sobol, ZSobol and random sampling, deterministic offline rendering and adaptive sampling.
• Tone mapping, color grading, bloom, shadow catchers, transparent backgrounds and depth of field.
• API documentation, procedural examples and a viewer for exploring scenes and exporting images.
