Detailed Description

Provides access to the details of a glTF MeshPrimitive loaded by the Cesium3DTileset.

This interface is implemented by the USceneComponent subclass that represents a single glTF primitive that is part of the tile's glTF model.

virtual std::optional< uint32_t > ICesiumLoadedTilePrimitive::FindTextureCoordinateIndexForGltfAccessor ( int32_t AccessorIndex ) const

pure virtual

Maps an accessor index in the glTF primitive to its corresponding texture coordinate index in the Unreal mesh.

The -1 key is reserved for implicit feature IDs (in other words, the vertex index).

Parameters

AccessorIndex An accessor index in the glTF primitive

Returns: A texture coordinate index in the Unreal mesh, or std::nullopt if none was found for the AccessorIndex passed.

virtual ICesiumLoadedTile & ICesiumLoadedTilePrimitive::GetLoadedTile ( )

pure virtual

Gets the loaded tile that this primitive belongs to.

virtual UStaticMeshComponent & ICesiumLoadedTilePrimitive::GetMeshComponent ( )

pure virtual

Gets the Unreal static mesh component built to represent the glTF primitive.

virtual const CesiumGltf::MeshPrimitive * ICesiumLoadedTilePrimitive::GetMeshPrimitive ( ) const

pure virtual

Gets the glTF primitive.

virtual const FCesiumPrimitiveFeatures & ICesiumLoadedTilePrimitive::GetPrimitiveFeatures ( ) const

pure virtual

Gets the Blueprint-accessible wrapper for the glTF Primitive's mesh features.

virtual const FCesiumPrimitiveMetadata & ICesiumLoadedTilePrimitive::GetPrimitiveMetadata ( ) const

pure virtual

Gets the Blueprint-accessible wrapper for the glTF Primitive's EXT_structural_metadata extension.
