AKA - "The calibration transfer function" The purpose of this extension is to enable consistent material representation under highly varying lighting conditions while at the same time retaining color representation...
This is a continuation of #1850 which seems to have gone stale and is based on a fork of glTF in the UX3D repo. The purpose of this extension is...
Development of this PR is halted until #1956 is finialized. This extension started out as needed by KHR_lights_environment but the functionality is now moved into that extension The purpose of...
A 3D scene created by one of our 3D modellers, it contains a setup with a couple of IKEA items. The scene has lights and camera to create the desired...
The purpose of this model is to have a performance test for a demanding node, mesh and material usecase. Each node references unique geometry and material, there are in total...
One way of declaring an extension that will provide a light scale factor to be used in shading to produce valid display output. This is done by way of declaring...
In order for the glTF sample viewer to be physically correct the specular normal distribution factor - D_GGX in the shader - must be clamped to [0.0- 1.0] This factor,...
As clearcoat is an additional layer (with IOR 1.5) that light interacts with prior to interaction with the base-layer, there shall be no Fresnel reflection in the base-layer (unless material...
There are no specular highlights when roughness = 0.0 The likely cause for this is that the NDF function needs to limit roughness to a small value. Since glTF does...
The purpose of this extension is to enable use of HDR material textures by means of texture float format VK_FORMAT_R16G16B16_SFLOAT. KTX v2 shall be used as a container, the extension...
