Methods


o AddReference
public AddReference()
Increments the reference counter of the mapping operator.
o ComputeTextureCoordinates
public virtual ComputeTextureCoordinates( const iVertex,
const iNbVertex,
const iNormals,
const iNbNormals,
const iTuv,
const iNbuv,
oTexture)
Computes the texture coordinates for all vertices.
Parameters:
iVertex
Array containing the coordinates of every vertices,as a succession of (x,y,z) sets.
iNbVertex
Number of vertices in iVertex.
iNormals
Array containing the coordinates of the normals at every vertices, as a succession of (Nx,Ny,Nz) sets. If the surface is plane, the only given set is valid for all vertices.
iNormals
Number of normal sets in iNormals.
iTuv
Array containing the parameters in of every vertices in the surface parametrization space, as a succession of (u,v) sets. This array must be required by the mapping operator through the method NeedUVMesh.
iNbuv
Number of parameter sets in iNbuv.
oTexture
Array containing the coordinates of texture coordinates for every vertices, as a succession of (s,t,0) sets.
(0,0,0) always indicates the lower-left corner of the texture image.
(1,1,0) always indicates the upper-right corner of the texture image.
o ComputeTextureCoordinates
public virtual ComputeTextureCoordinates( const iVertex,
const iNbVertex,
const iNormales,
const iNbNormales,
const iTuv,
const iNbuv,
oTexture,
const iCell)
Computes the texture coordinates for all vertices. Overload this method only if you need access to the topological cell. Otherwise, use other method.
Parameters:
iVertex
Array containing the coordinates of every vertices,as a succession of (x,y,z) sets.
iNbVertex
Number of vertices in iVertex.
iNormals
Array containing the coordinates of the normals at every vertices, as a succession of (Nx,Ny,Nz) sets. If the surface is plane, the only given set is valid for all vertices.
iNormals
Number of normal sets in iNormals.
iTuv
Array containing the parameters in of every vertices in the surface parametrization space, as a succession of (u,v) sets. This array must be required by the mapping operator through the method NeedUVMesh.
iNbuv
Number of parameter sets in iNbuv.
oTexture
Array containing the coordinates of texture coordinates for every vertices, as a succession of (s,t,0) sets.
(0,0,0) always indicates the lower-left corner of the texture image.
(1,1,0) always indicates the upper-right corner of the texture image.
iCell
Topological cell for which we are calculating the textures coordinates.
o Destroy
public virtual Destroy()
Deletes the mapping operator.
o GetId
public GetId()
Return the id of the mapping operator. This id is not persistent. It only serves to index different sets of mapping coordinates on CATGraphicPrimitives.
o GetReferenceNumber
public GetReferenceNumber()
Returns the reference counter value of the mapping operator.
o NeedUVMesh
public virtual NeedUVMesh()
Indicates the need for surface parameters array iTuv.
o SubReference
public SubReference()
IDecrements the reference counter of the mapping operator.
