public class SbPlaneProjector extends SbProjector
Plane projector. SbPlaneProjector projects the mouse onto a plane. This is typically used to write interactive 3D manipulators and viewers.

  • Constructor Details

    • SbPlaneProjector

      public SbPlaneProjector()
      Calls SbPlaneProjector(false).

    • SbPlaneProjector

      public SbPlaneProjector(SbPlane plane)
      Calls SbPlaneProjector(plane, false).

    • SbPlaneProjector

      public SbPlaneProjector(SbPlane plane, boolean orient)
      Constructor which is passed a plane. If orient to eye is true, the plane will be reoriented to the eye.

    • SbPlaneProjector

      public SbPlaneProjector(boolean orient)
      Constructor. The default plane passes through the origin and is oriented perpendicular to the Z axis.

  • Method Details

    • setStartPosition

      public void setStartPosition(SbVec3f point)
      Sets the initial position from a point on the projector.

    • setOrientToEye

      public void setOrientToEye(boolean orientToEye)
      Sets whether the projector should be oriented towards the eye. If orientToEye is set to true, the given plane's direction is ignored, and the plane will be oriented to the eye. It will pass through the same point from the origin defined by the original dir * dist. Set to false if the plane's direction should remain in working space.

    • getVector

      public SbVec3f getVector(SbVec2f mousePosition1, SbVec2f mousePosition2)
      Gets a vector on this plane given two normalized mouse positions.

    • setPlane

      public void setPlane(SbPlane plane)
      Sets the plane to use.

    • isOrientToEye

      public boolean isOrientToEye()
      Gets whether the projector should be oriented towards the eye.

    • setStartPosition

      public void setStartPosition(SbVec2f mousePosition)
      Sets the initial mouse position.

    • getPlane

      public SbPlane getPlane()
      Gets the plane to use.

    • getVector

      public SbVec3f getVector(SbVec2f mousePosition)
      Gets a vector given the current mouse point. Uses the last point on this projector from the previous call to getVector() or setStartPostion(). Do not use this if the working space transform is changing since the new point will be in a different space than the old one.
