Geometry::setPolygonVertex

Alters the position of a polygon's vertex inside a geometry object.

C++ Syntax

FMOD_RESULT Geometry::setPolygonVertex(
  int index,
  int vertexindex,
  const FMOD_VECTOR *vertex
);

C Syntax

FMOD_RESULT FMOD_Geometry_SetPolygonVertex(
  FMOD_GEOMETRY *geometry,
  int index,
  int vertexindex,
  const FMOD_VECTOR *vertex
);

Parameters

index: Polygon index. This must be in the range of 0 to Geometry::getNumPolygons minus 1.
vertexindex: Vertex index inside the polygon. This must be in the range of 0 to Geometry::getPolygonNumVertices minus 1.
vertex: Address of an FMOD_VECTOR which holds the new vertex location.

Return Values

If the function succeeds then the return value is FMOD_OK.
If the function fails then the return value will be one of the values defined in the FMOD_RESULT enumeration.

Remarks

Note! There may be some significant overhead with this function as it may cause some reconfiguration of internal data structures used to speed up sound-ray testing.
