Description:

Gets a world 3-D, or Euclidean, control point at the given (u, v) index. The 4-D representation is (x, y, z, 1.0).

Syntax:
public bool GetPoint(
int u,
int v,
out Point3d point
)
Parameters:
  • u
  • Type: int
  • Index of control point in the surface U direction.
  • v
  • Type: int
  • Index of control point in the surface V direction.
  • point
  • Type: Point3d
  • Coordinate of control point.
Returns:
Type: bool
True on success, False on failure.
Available since:
6.0
Description:

Gets a homogeneous control point at the given (u, v) index, where the 4-D representation is (x, y, z, w). The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).

Syntax:
public bool GetPoint(
int u,
int v,
out Point4d point
)
Parameters:
  • u
  • Type: int
  • Index of control point in the surface U direction.
  • v
  • Type: int
  • Index of control point in the surface V direction.
  • point
  • Type: Point4d
  • Coordinate and weight of control point.
Returns:
Type: bool
True on success, False on failure.
Remarks:
For expert use only. If you do not understand homogeneous coordinates, then use the override that returns world 3-D, or Euclidean, coordinates.
