◆ ComputeElementNormals3() [1/2]
| void ANSYS::Nexus::GLTFWriter::Utils::ComputeElementNormals3 | ( | const unsigned int | numVertices, |
| const float * | vertices, | ||
| const unsigned int | numElements, | ||
| const unsigned int | elementSize, | ||
| const unsigned int * | indices, | ||
| float * | normals | ||
| ) |
Computes XYZ element normals from vertices and elements. unsigned int and unsigned short indices are supported.
- Parameters
-
[in] numVertices Number of vertices. [in] vertices XYZ vertex data. [in] numElements Number of elements. [in] elementSize Number of vertices in element. [in] indices Vertex indices of element. [in] normals Memory into which element normals are inserted. This is preallocated to a size of 3 * numVertices floats.
◆ ComputeElementNormals3() [2/2]
| void ANSYS::Nexus::GLTFWriter::Utils::ComputeElementNormals3 | ( | const unsigned int | numVertices, |
| const float * | vertices, | ||
| const unsigned int | numElements, | ||
| const unsigned int | elementSize, | ||
| const unsigned short * | indices, | ||
| float * | normals | ||
| ) |
Computes XYZ element normals from vertices and elements. unsigned int and unsigned short indices are supported.
- Parameters
-
[in] numVertices Number of vertices. [in] vertices XYZ vertex data. [in] numElements Number of elements. [in] elementSize Number of vertices in element. [in] indices Vertex indices of element. [in] normals Memory into which element normals are inserted. This is preallocated to a size of 3 * numVertices floats.
◆ ComputeVertexNormals3() [1/2]
| void ANSYS::Nexus::GLTFWriter::Utils::ComputeVertexNormals3 | ( | const unsigned int | numVertices, |
| const float * | vertices, | ||
| const unsigned int | numElements, | ||
| const unsigned int | elementSize, | ||
| const unsigned int * | indices, | ||
| float * | normals | ||
| ) |
Computes XYZ vertex normals from vertices and elements. The element normals for all elements adjacent to a vertex are combined to get the vertex normal. unsigned int and unsigned short indices are supported.
- Parameters
-
[in] numVertices Number of vertices. [in] vertices XYZ vertex data. [in] numElements Number of elements. [in] elementSize Number of vertices in element. [in] indices Vertex indices of element. [in] normals Memory into which vertex normals are inserted. This is preallocated to a size of 3 * numElements floats.
◆ ComputeVertexNormals3() [2/2]
| void ANSYS::Nexus::GLTFWriter::Utils::ComputeVertexNormals3 | ( | const unsigned int | numVertices, |
| const float * | vertices, | ||
| const unsigned int | numElements, | ||
| const unsigned int | elementSize, | ||
| const unsigned short * | indices, | ||
| float * | normals | ||
| ) |
Computes XYZ vertex normals from vertices and elements. The element normals for all elements adjacent to a vertex are combined to get the vertex normal. unsigned int and unsigned short indices are supported.
- Parameters
-
[in] numVertices Number of vertices. [in] vertices XYZ vertex data. [in] numElements Number of elements. [in] elementSize Number of vertices in element. [in] indices Vertex indices of element. [in] normals Memory into which vertex normals are inserted. This is preallocated to a size of 3 * numElements floats.
