v2.0.0

Performance Optimization

Adaptive Quality Levels

9 configurable quality levels automatically adjust rendering parameters based on device capabilities. Each quality level automatically adjusts multiple rendering parameters to achieve the desired balance:

• Spherical Harmonics (SH) Degree: Controls lighting complexity and color accuracy
• Pixel Thresholds: Determines minimum/maximum renderable Gaussian sizes
• Transparency Thresholds: Sets minimum opacity for rendering
• Computational Approximations: Enables performance optimizations at lower levels
• Sorting Bucket Count: Adjusts depth sorting precision

Smart Sorting Algorithms

Multiple sorting strategies optimized for different viewing scenarios, each optimized for different rendering scenarios:

• Type 1: Default View Projection Sorting
• Type 2010: Near-Only Rendering
• Type 2011: Front-Face Culling
• Type 2012: Two-Segment Sorting with Culling
• Type 2112: Full Two-Segment Sorting

v1.7.0

• Upgraded the SPX format to version 2, adding support for the WebP encoding format for more significant compression.
• Added support for rendering SPX v2 models, along with improvements and fixes for several known issues.
• Added support for rendering SOG format models (both v1 and v2). SOG utilizes WebP encoding, resulting in superior compression.

v1.6.0

• Add support for .spz version 3 format

v1.5.0

• Add support for npm package @reall3d/reall3dviewer
• Add build-in viewer Reall3dMapViewer
• Optimized focus marker, viewer options, splatmesh options, etc
• Fix known issues.

v1.4.0

• Add support for the .ply file format.
• Add support for the .spz file format.
• Fix known issues.

v1.3.0

• .spx version 1
