spark/CHANGELOG.md

0.1.7 (July 30, 2025)

Image quality and performance improvements.

Enhancements

• Allow custom splat encoding ranges (rgb, sh1, sh2, sh3). Expose premultipliedAlpha flag to use when accumulating splat RGB (#134) (@asundqui)
• Add higher precision mode (float32) for splat sorting in addition to the default one (float16) (@asundqui, @mrxz) (#129)
• Allow decoding and parsing of SOGS images to happen in parallel (@mrxz) (#122)
• New splat shaders effect example (#141) (@kali-shade)
• Expose minAlpha and maxPixelRadius in the SparkRenderer parameters (#130) (@asundqui)
• Tree-shaking on worker code (@mrxz) (#118)
• Add JSDocs to docs (@mrxz) (#123)
• Use THREE.js built-in full screen quad instead of custom setup to cover the entire render target (@mrxz) (#121)
• Redunce bundle size by removing anyhow::anyhow dependency (#127) (@asundqui)

Deprecations

• Remove SparkRenderer blending parameter. Rely instead on THREE.js built-in support for premultipliedAlpha that sets the right blending mode automatically (#136) (@mrxz)

0.1.6 (July 11, 2025)

Visual quality improvements, .zip sogs file support, bug fixes.

Enhancements

• Can load SOGS compressed splats packaged in a .zip file (#100) (@asundqui)
• Rename SparkRenderer renderScale parameter to focalAdjustment (#113) (fix #99) (@asundqui, @mrxz)
• Use OffscreenCanvas and WebGL2 context to decode webp SOGS images instead of 3rd party dependency (#90) (@mrxz)
• Animated transitions between splats example (#69) (@winnie1994)
• Example of loading a SOGS compressed splat (@dmarcos, @vincentwoo, @61cygni)
• Expand value range of internal splat encoding to improve visual quality. Lower zero cut-off to retain and render small splats. (#110) (@asundqui, @mrxz)

Bug fixes

• Fix visible property of SplatMesh not having effect. (fix #77) (#100) (@asundqui, @cyango)
• Add missing sh1 and sh2 support to SOGS compressed support (fix #108) (#109) (@lucasoptml)
• Prevent unintentional reuse of ArrayBuffer on concurrent file requests or hits to THREE.Cache. Replace use of THREE.FileLoader with fetch API (#94, #112) (fix #93) (@mrxz, @asundqui)

0.1.5 (July 1, 2025)

Visual quality improvements and SOGS support

Enhancements

• Add support for SOGS compression format 3D Gaussian Splatting (#73) (@asundqui)
• Change splat shapes by using any RGBA texture to compute the Gaussian falloff (#79) (@asundqui)
• Use RenderTarget properties to reduce manual render state tracking (#80) (@mrxz)

Bug fixes

• Visual quality, Fix .ksplat decoding (fix #66) (@asundqui)
• Visual quality, Fix Spherical Harmonics not included in SPZ transcoding (fix #66) (#83) (@asundqui)
• Visual quality, Fix incorrect calculation of renderer size. Especially improves rendering in high DPI displays (#71) (@mrxz)
• Fix support of compressed .ply files exported from SuperSplat. Newer versions include min/max_r/g/b properties in the header that were not parsed (#82) (@asundqui)

0.1.4 (June 24, 2025)

Enhancements

• Ability to render depth and normal values (#58) (@asundqui)
