Noeri Huisman 30f50aa9ee Use material.premultipliedAlpha to adjust blending function (#136) 2025-07-25 03:26:29 +02:00
Andreas Sundquist f60c2b0cf9 Custom/extended splat encoding ranges, Premultiplied alpha for hyper-saturated colors (#134)
* Externalized SparkRenderer.maxPixelRadius and .minAlpha settings. Added to documentation. Added to examples/editor under Debug folder, moved sort32 there.

* Added SplatEncoding concept, applied individually to SparkRenderer (rgbMin/Max, lnScaleMinMax), SplatMesh (additionally sh1Min/Max, sh2, sh3). Updated examples/editor to control settings via gui. Updated all related code to pipe along settings where needed.
Added SparkRenderer.premultipliedAlpha to control blend mode and enable hyper-saturated color contributions by default.

* Fix SplatLoader not passing along encoding. Complete renaming to splat encoding.

Andreas Sundquist 5eb57038b4 Externalize render settings minAlpha and maxPixelRadius (#130)
* Add commented benchmarkSort to compare JS vs Wasm sorting.

* Add 32-bit float sort via SparkViewpooint.sort32, using 2-pass radix-65536 sort. Turn on sort32 by default for examples/editor. Implemented Rust sort and JS sort, updated benchmarking code to include float16 and float32 sort.

* Add sort32 to docs/spark-viewpoint.md.

* Externalized SparkRenderer.maxPixelRadius and .minAlpha settings. Added to documentation. Added to examples/editor under Debug folder, moved sort32 there.

Andreas Sundquist 0639f2f963 Rename SparkRenderer.renderScale to focalAdjustment. Add to constructor options and to docs. (#113) 2025-07-11 21:59:05 -04:00
Andreas Sundquist dc07e02a33 Expand internal splat scale encoding to e^[-12,9]. Lower zero cut-off to e^-30. Fix background color selection in editor. (#110) 2025-07-11 10:48:10 -07:00
Andreas Sundquist 179885595c Splat Texture (#79)
* Add experimental Splat Texture rendering and examples/splat-texture. Added star.png and heart.png to assets.json and to assets repo. Update examples/depth-of-field to compute from metric aperture size. Added SparkRenderer.renderScale debug parameter. Updated examples/editor: set default highDPI to true, added logFocalDistance, apertureAngle, refactored, grouped into debugFolder, default settings open, preset buttons for nonAA and AA settings.

* Set default highDpi in examples/editor to not(isMobile).

Andreas Sundquist db1e880ae1 Add focalDistance and apertureAngle to SparkRenderer. Add examples/depth-of-field. (#59) 2025-06-20 17:09:43 -07:00
Andreas Sundquist 7a4142c62a Lower MIN_ALPHA from 0.01 to 0.5/255, the lowest conceivable value that could be encoded in a Uint8, allowing highly transparent objects to render better. (#37)
Add "sortRadial" option to Editor to allow toggling between radial and Z-depth sorting.
