Sceneform 1.6pr3

This release of Filament is a check point release towards Sceneform 1.6.

Features

Runtime

• Added WebGL/WASM support
• Skinning supports non-rigid transforms
• Add the ability to mirror a frame (for video recording for instance)
• Removed dependencies on OpenGL ES 3.1 for iOS
• The clear coat layer's roughness influences the roughness of the base layer

Tools

• Added ASTC/S3TC/ETC2 texture compression support (cmgen can output compressed textures for instance)
• Added KTX export
• Added mipmap generation tool mipgen
• cmgen can generate equirectangular maps
• Many improvements to Tungsten, Filament's visual material editor (IBL, textures support, lighting, etc.)

Samples

• New Android sample applications in Kotlin
• Added WebGL samples

Optimizations

• Skip a copy when updating per-renderable uniform buffers
• Store all per-renderable uniform blocks in a single buffer
• Use slightly optimized Fresnel term on mobile
• Folded the Lambert BRDF in the Spherical Harmonics
• Skip lighting and shadowing in the shaders when possible

Bug fixes

• Fixed division by 0 in the froxelization pass
• Fixed division by 0 in cmgen
• Fixed Vulkan crash
• Fixed invalid SPIR-V generation
• Fixed the anisotropic BRDF on mobile
• Fixed Fresnel term when f90 was less than 1 on desktop
• Fixed cubemaps mirroring in cmgen
• Make shadowMultiplier objets transparent when not lit

Improvements

• Revamped RGBM support
• Improved the quality of the IBLs generated by cmgen
• Improved cubemap generation and handling in cmgen
• Improved Java APIs for Kotlin
• Better support fo grayscale images in tools
• Moved from OpenEXR to TinyEXR
• Various other fixes for minor bugs and crashes

Initial public release update

This release of Filament is a small update to the initial release. Windows binaries are now available.

Features

• Added clearCoatNormal property to set a normal map on the clear coat layer
• Switch the cloth material model to a more intuitive parameterization/BRDF

Optimizations

• Optimizations in the lights assignment process
• Better multi-threading of the lights assignment process
• Reduced memory usage of the lights assignment process
• Post-processing shaders do not use highp computations anymore

Bug fixes and improvements

• Complete revamp of libimage
• Bug fixes to lights assignement
• cmgen did not process cross cube maps properly
• cmgen could sometimes use uninitialized memory when computing spherical harmonics
• Updated glslang, spirv-cross and spirv-tools
• Various fixes in the Vulkan backend
