FMeshDescriptionTriangleMeshAdapter

Basic struct to adapt a [FMeshDescription](API\Runtime\MeshDescription\FMeshDescription) for use by GeometryProcessing classes that template the mesh type and expect a standard set of basic accessors For example, this adapter will let you use a [FMeshDescription](API\Runtime\MeshDescription\FMeshDescription) with GeometryProcessing's TMeshAABBTree3 See also the Editable version below

Syntax

struct FMeshDescriptionTriangleMeshAdapter

Remarks

Basic struct to adapt a FMeshDescription for use by GeometryProcessing classes that template the mesh type and expect a standard set of basic accessors For example, this adapter will let you use a FMeshDescription with GeometryProcessing's TMeshAABBTree3 See also the Editable version below

Usage example given some const FMeshDescription* Mesh: FMeshDescriptionAABBAdapter MeshAdapter(Mesh); // adapt the mesh TMeshAABBTree3 AABBTree(&MeshAdapter); // provide the adapter to a templated class like TMeshAABBTree3
