Function Documentation

◆ VuoMeshUtility_calculateCubicUVs()

void VuoMeshUtility_calculateCubicUVs ( VuoSubmesh * submesh )

Generate cubic UVs for this submesh.

Works best with IndividualTriangles meshes where no vertex is shared between triangles.

◆ VuoMeshUtility_calculateCubicUVsPerTriangle()

void VuoMeshUtility_calculateCubicUVsPerTriangle ( VuoSubmesh * submesh )

Generate cubic UVs for this submesh, using the triangle normal to project UV instead of vertex normal.

◆ VuoMeshUtility_calculateNormals()

void VuoMeshUtility_calculateNormals ( VuoSubmesh * submesh )

Generate normals for this submesh.

Vertices pointed at by multiple element indices will be averaged.

◆ VuoMeshUtility_calculateSphericalUVs()

void VuoMeshUtility_calculateSphericalUVs ( VuoSubmesh * submesh )

Generate spherical UVs for this submesh.

◆ VuoMeshUtility_calculateTangents()

void VuoMeshUtility_calculateTangents ( VuoSubmesh * submesh )

Generate tangents and bitangents for this submesh.

Assumes triangles are wound using VuoMesh_IndividualTriangles, and that the positions, textures, normals, and triangles arrays are valid.

◆ VuoMeshUtility_faceNormal()

static VuoPoint4d VuoMeshUtility_faceNormal	(	VuoPoint4d	a,
		VuoPoint4d	b,
		VuoPoint4d	c
	)

inlinestatic

Calculates the face normal for position vertices a, b, and c.

◆ VuoMeshUtility_insertSeam()

void VuoMeshUtility_insertSeam ( VuoSubmesh * submesh )

Inserts a seam along a vertical line on the left side of a mesh.

May (probably will) leave unused vertices.

◆ VuoMeshUtility_removeUnusedVertices()

void VuoMeshUtility_removeUnusedVertices ( VuoSubmesh * mesh )

Remove unused vertices in a mesh.

This should usually be called after a seam is inserted.
