class | UsdSchemaRegistry |
Encodes a tetrahedral mesh. A tetrahedral mesh is defined as a set of tetrahedra. Each tetrahedron is defined by a set of 4 points, with the triangles of the tetrahedron determined from these 4 points as described in the tetVertexIndices attribute description. The mesh surface faces are encoded as triangles. Surface faces must be provided for consumers that need to do surface calculations, such as renderers or consumers using physics attachments. Both tetrahedra and surface face definitions use indices into the TetMesh's points attribute, inherited from UsdGeomPointBased.
Construct a UsdGeomTetMesh on UsdPrim prim
. Equivalent to UsdGeomTetMesh::Get(prim.GetStage(), prim.GetPath()) for a valid prim
, but will not immediately throw an error for an invalid prim
|
inlineexplicit |
Construct a UsdGeomTetMesh on the prim held by schemaObj
. Should be preferred over UsdGeomTetMesh(schemaObj.GetPrim()), as it preserves SchemaBase state.

Returns the kind of schema this class belongs to.
Reimplemented from UsdGeomPointBased.

ComputeSurfaceFaces determines the vertex indices of the surface faces from tetVertexIndices. The surface faces are the set of faces that occur only once when traversing the faces of all the tetrahedra. The algorithm is O(nlogn) in the number of tetrahedra. Method returns false if surfaceFaceIndices argument is nullptr and returns true otherwise. The algorithm can't be O(n) because we need to sort the resulting surface faces for deterministic behavior across different compilers and OS.

Attempt to ensure a UsdPrim adhering to this schema at path
is defined (according to UsdPrim::IsDefined()) on this stage.
If a prim adhering to this schema at path
is already defined on this stage, return that prim. Otherwise author an SdfPrimSpec with specifier == SdfSpecifierDef and this schema's prim type name for the prim at path
at the current EditTarget. Author SdfPrimSpec s with specifier
== SdfSpecifierDef and empty typeName at the current EditTarget for any nonexistent, or existing but not Defined ancestors.
The given path must be an absolute prim path that does not contain any variant selections.
If it is impossible to author any of the necessary PrimSpecs, (for example, in case path cannot map to the current UsdEditTarget's namespace) issue an error and return an invalid UsdPrim.
Note that this method may return a defined prim whose typeName does not specify this schema class, in case a stronger typeName opinion overrides the opinion at the current EditTarget.

Return a UsdGeomTetMesh holding the prim adhering to this schema at path
on stage
. If no prim exists at path
on stage
, or if the prim at that path does not adhere to this schema, return an invalid schema object. This is shorthand for the following:

Return a vector of names of all pre-declared attributes for this schema class and all its ancestor classes. Does not include attributes that may be authored by custom/extended methods of the schemas involved.
USDGEOM_API UsdAttribute UsdGeomTetMesh::GetSurfaceFaceVertexIndicesAttr | ( | ) | const |
surfaceFaceVertexIndices<> defines the triangle surface faces indices wrt. points<> of the tetmesh surface. Again the orientation<> attribute inherited from UsdGeomPrim should be set accordingly. The orientation<> for faces of tetrahedra and surface faces must match.
Declaration | int3[] surfaceFaceVertexIndices |
C++ Type | VtArray<GfVec3i> |
Usd Type | SdfValueTypeNames->Int3Array |
USDGEOM_API UsdAttribute UsdGeomTetMesh::GetTetVertexIndicesAttr | ( | ) | const |
Flat list of the index (into the points<> attribute) of each vertex of each tetrahedron in the mesh. Each int4 corresponds to the indices of a single tetrahedron. Users should set the orientation<> attribute of UsdGeomPrim accordingly. That is if the orientation<> is "rightHanded", the CCW face ordering of a tetrahedron is [123],[032],[013],[021] with respect to the int4. This results in the normals facing outward from the center of the tetrahedron. If the orientation<> attribute is set to "leftHanded" the face ordering of the tetrahedron is [321],[230],[310],[120] and the leftHanded CW face normals point outward from the center of the tetrahedron. Setting the orientation<> attribute to align with the ordering of the int4 for the tetrahedrons is the responsibility of the user.
