Struct IndexedTextureMap 

pub struct IndexedTextureMap<'m, 's> { /* private fields */ }

Borrowed projection of an indexed texture map (IfcIndexedTriangleTextureMap or IfcIndexedPolygonalTextureMap): binds a texture to a tessellated face set via per-vertex texture-coordinate indices.

Implementations

impl<'m, 's> IndexedTextureMap<'m, 's>

pub fn id(&self) -> EntityId

The entity id of this texture map.

pub fn type_name(&self) -> &'m str

The concrete IFC entity type name.

pub fn maps(&self) -> StyleResult<Vec<EntityId>>

The Maps attribute: the textures this map applies. Mandatory.

LIST [1:?] OF IfcSurfaceTexture in both IFC4 and IFC4X3. It is a list even when, as is usual, it holds a single texture.

pub fn mapped_to(&self) -> StyleResult<EntityId>

The MappedTo attribute: the tessellated face set this map applies to. Mandatory.

pub fn tex_coord_index(&self) -> StyleResult<Option<&'m Value>>

The TexCoordIndex attribute: per-face indices into TexCoords, when authored.

pub fn tex_coords(&self) -> StyleResult<EntityId>

The TexCoords attribute: the indexed texture-vertex list. Mandatory.

pub fn triangle_coordinates( &self, triangle_count: usize, ) -> StyleResult<Option<TriangleTextureCoordinates>>

Per-corner texture coordinates for an IfcIndexedTriangleTextureMap.

triangle_count is the CoordIndex length of the mapped face set. Returns Ok(None) for the polygonal variant, which indexes through IfcTextureCoordinateIndices instead, and when TexCoordIndex is omitted, whose meaning the schema leaves undefined.

Errors

A malformed TexCoordsList, a TexCoordIndex entry that addresses a missing texture vertex, or more mapped triangles than the face set has.
