Polygon iterator.
This class is the iterator for polygonal surfaces (meshes).
The iterator functions in two modes depending on whether a component is specified. When a component is not given or is NULL the iteration will be over all polygons for the surface. When a component is given this iterator will iterate over the polygons (faces) specified in the component. When iterating over components a DAG path to the surface must also be supplied.

[out] | ReturnStatus | Status code |
MStatus numConnectedFaces | ( | int & | faceCount | ) | const |
This method checks for the number of connected faces.
[out] | faceCount | Storage for the face count |
MStatus numConnectedEdges | ( | int & | edgeCount | ) | const |
This method checks for the number of connected edges on the vertices of this face.
[out] | edgeCount | Storage for the edge count |
bool onBoundary | ( | MStatus * | ReturnStatus = NULL | ) |
This method determines whether the current face is on a boundary.
[out] | ReturnStatus | Status code |
MStatus getArea | ( | double & | area, |
MSpace::Space | space = MSpace::kObject |
||
) |
This method gets the area of the face.
[out] | area | The area |
[in] | space | World Space or Object Space |
bool zeroArea | ( | MStatus * | ReturnStatus = NULL | ) |
This method checks if its a zero area face.
[out] | ReturnStatus | Status code |
This method gets the UV area of the face.
[out] | area | The uv area |
[in] | uvSet | UV set to work with |
bool zeroUVArea | ( | MStatus * | ReturnStatus = NULL | ) |
This method checks if the UV area of the face is zero.
[out] | ReturnStatus | Status code |
This method checks if the UV area of the face is zero.
[in] | uvSet | UV set to work with |
[out] | ReturnStatus | Status code |
bool isConvex | ( | MStatus * | ReturnStatus = NULL | ) |
This method checks if the face is convex.
[out] | ReturnStatus | Status code |
bool isStarlike | ( | MStatus * | ReturnStatus = NULL | ) |
This method checks if the face is starlike.
That is, a line from the centre to any vertex lies entirely within the face.
[out] | ReturnStatus | Status code |
bool isLamina | ( | MStatus * | ReturnStatus = NULL | ) |
This method checks if the face is a lamina (the face is folded over onto itself).
[out] | ReturnStatus | Status code |
bool isHoled | ( | MStatus * | ReturnStatus = NULL | ) |
This method checks if the face has any holes.
[out] | ReturnStatus | Status code |
bool isPlanar | ( | MStatus * | ReturnStatus = NULL | ) |
This method checks if the face is planar.
[out] | ReturnStatus | Status code |
This method checks if the winding order of UV's for this face are reversed (clockwise), or not (counter clockwise)
[in] | uvSet | UV set to work with |
[out] | ReturnStatus | Status code |
