Class MaterialProvider.MaterialKey

  • Enclosing interface:
    MaterialProvider
    public static class MaterialProvider.MaterialKey
extends java.lang.Object
    MaterialKey specifies the requirements for a requested glTF material. The provider creates Filament materials that fulfill these requirements.

        public void constrainMaterial​(@NonNull @Size(min=8L)
                              int[] uvmap)
        Populate UV map according to the material key, altering latter if required. Filament supports up to 2 UV sets. glTF has arbitrary texcoord set indices, but it allows implementations to support only 2 simultaneous sets. Here we build a mapping table with 1-based indices where 0 means unused. Note that the order in which we drop textures can affect the look of certain assets. This "order of degradation" is stipulated by the glTF 2.0 specification.
        Parameters:
        uvmap - Output argument that gets populated with a small table that maps from a glTF uv index to a Filament uv index (0 = UNUSED, 1 = UV0, 2 = UV1).
