VTK-class vtktexturemaptocylinder: texture ing algorithm, ing of the cylindrical texture

Generate texture coordinates from the ing point set to the surface of the cylinder

Vtktexturemaptocylinder is a filter that generates 2D texture coordinates and maps the input texture dataset to a cylindrical string. The range can be specified by the user or automatically generated. (A cylinder is the center of an automatically generated computing cylinder ). Note the range between the generated texture coordinates (0, 1.
