Member Function Documentation

computeFacesFromPolygonVertex()

static C3D_API void castor3d::SubmeshUtils::computeFacesFromPolygonVertex ( castor::Point3fArray & texcoords, TriFaceMapping const & triFace )

static

Creates faces from the points.

Remarks

This function assumes the points are sorted like triangles fan.

Parameters

[in,out]	texcoords	The texture coordinates.
[in,out]	triFace	The component that will receive the computed triangles.

computeNormals()

static C3D_API void castor3d::SubmeshUtils::computeNormals ( castor::Point3fArray const & positions, castor::Point3fArray & normals, FaceArray const & triFace, bool reverted = false )

static

Generates normals.

Parameters

[in]	positions	The vertices positions.
[out]	normals	The vertices normals.
[in]	triFace	The triangles.
[in]	reverted	Tells if the normals must be inverted.

computeTangentsFromNormals()

static C3D_API void castor3d::SubmeshUtils::computeTangentsFromNormals ( castor::Point3fArray const & positions, castor::Point3fArray const & texcoords, castor::Point3fArray const & normals, castor::Point4fArray & tangents, FaceArray const & faces )

static

Computes tangent for each vertex of the submesh.

Remarks

This function supposes the normals are defined.

Parameters

[in]	positions	The vertices positions.
[in]	texcoords	The vertices texture coordinates.
[in]	normals	The vertices normals.
[out]	tangents	The vertices tangents.
[in]	faces	The triangles.
