Indicates that a face has no neighbour over a particular edge.

Enumeration Type Documentation

enum CC3VertexContent

This enum defines the components of a bitwise-OR of flags enumerating the types of vertex content contained within a mesh.

Valid components of this type include biwise-OR combinations of the the values in this enum.

An absence of any bitwise-OR components in a CC3VertexContent is represented by kCC3VertexContentNone.

All valid meshes must contain a kCC3VertexContentLocation, and a meshes will raise an assertion if an attempt is made to set the vertex content without that component.

Enumerator
kCC3VertexContentNone	Bitwise-OR component of CC3VertexContent variables that indicates an absence of any vertex content.
kCC3VertexContentLocation	Bitwise-OR component of CC3VertexContent variables that indicates each vertex contains location information. Vertices must always include location info.
kCC3VertexContentNormal	Bitwise-OR component of CC3VertexContent variables that indicates each vertex contains normal information. This component is required if and only if the mesh is to interact with light sources.
kCC3VertexContentTangent	Bitwise-OR component of CC3VertexContent variables that indicates each vertex contains tangent information. This component is required if and only if the mesh is using tangent-space bump-mapping.
kCC3VertexContentBitangent	Bitwise-OR component of CC3VertexContent variables that indicates each vertex contains bitangent information. This component is optionally included when the mesh is using tangent-space bump-mapping.
kCC3VertexContentColor	Bitwise-OR component of CC3VertexContent variables that indicates each vertex contains color information. This component is required if and only if each vertex on the mesh will have its own color. If this component is not included, all vertices in the mesh will have the color specified by the coloring properties of the material of the mesh node.
kCC3VertexContentTextureCoordinates	Bitwise-OR component of CC3VertexContent variables that indicates each vertex maps to a position on a texture. This component is required if and only if the mesh is covered by a texture.
kCC3VertexContentPointSize	Bitwise-OR component of CC3VertexContent variables that indicates each vertex contains point size information. This component is required if and only if the vertices are part of a point pariticle mesh, and each particle will have its own size. If this component is not included in a point particle mesh, all particles will have the same size.
kCC3VertexContentBoneWeights	Bitwise-OR component of CC3VertexContent variables that indicates each vertex contains a series of weights to allow the vertex to be manipulated by a series of weighted bones. This component is required if and only if the mesh is a vertex skinned mesh. This component requires that the kCC3VertexContentBoneIndices also be specified.
kCC3VertexContentBoneIndices	Bitwise-OR component of CC3VertexContent variables that indicates each vertex contains a series of bone indices to allow the vertex to be manipulated by a series of weighted bones. This component is required if and only if the mesh is a vertex skinned mesh. This component requires that the kCC3VertexContentBoneWeights also be specified.

Function Documentation

static CC3MeshIntersection* CC3NearestMeshIntersection ( CC3MeshIntersection *  meshHits, NSUInteger  hitCount  )

inlinestatic

Returns a pointer to the CC3MeshIntersection structure contained within the specified array of CC3MeshIntersection structures that has the smallest distance component.

The hitCount parameter indicates the size of the meshHits array. Returns NULL if hitCount is zero.

static NSString* NSStringFromCC3FaceNeighbours ( CC3FaceNeighbours  faceNeighbours)

inlinestatic

Returns a string description of the specified CC3FaceNeighbours struct.

static NSString* NSStringFromCC3MeshIntersection ( CC3MeshIntersection  mi)

inlinestatic

Returns a string description of the specified CC3MeshIntersection struct.

NSString* NSStringFromCC3VertexContent

(

CC3VertexContent

vtxContent)

Returns a string description of the specified vertex content components.
