## Detailed Description

represents an 3D object for placement in a rendered scene

Date:
  2003/01/21 20:34:38

Revision:
  1.36

vtkProp3D is an abstract class used to represent an entity in a rendering scene (i.e., vtkProp3D is a vtkProp with an associated transformation matrix). It handles functions related to the position, orientation and scaling. It combines these instance variables into one 4x4 transformation matrix as follows: [x y z 1] = [x y z 1] Translate(-origin) Scale(scale) Rot(y) Rot(x) Rot (z) Trans(origin) Trans(position). Both vtkActor and vtkVolume are specializations of class vtkProp. The constructor defaults to: origin(0,0,0) position=(0,0,0) orientation=(0,0,0), no user defined matrix or transform, and no texture map.

void vtkProp3D::SetUserTransform | ( | vtkLinearTransform * | transform | ) |

In addition to the instance variables such as position and orientation, you can add an additional transformation for your own use. This transformation is concatenated with the actor's internal transformation, which you implicitly create through the use of SetPosition(), SetOrigin() and SetOrientation().

If the internal transformation is identity (i.e. if you don't set the Position, Origin, or Orientation) then the actors final transformation will be the UserTransform, concatenated with the UserMatrix if the UserMatrix is present.

If the internal transformation is identity (i.e. if you don't set the Position, Origin, or Orientation) then the actors final transformation will be the UserTransform, concatenated with the UserMatrix if the UserMatrix is present.

void vtkProp3D::RotateY | ( | float |  | ) |

| Rotate the Prop3D in degrees about the Y axis using the right hand rule. The axis is the Prop3D's Y axis, which can change as other rotations are performed.

void vtkProp3D::RotateZ | ( | float |  | ) |

| Rotate the Prop3D in degrees about the Z axis using the right hand rule. The axis is the Prop3D's Z axis, which can change as other rotations are performed. To rotate about the world Z axis use RotateWXYZ (angle, 0, 0, 1). This rotation is applied before all others in the current transformation matrix.

| ) |

void vtkProp3D::GetOrientation | ( | float | o[3] | ) |

| Returns the orientation of the Prop3D as s vector of X,Y and Z rotation. The ordering in which these rotations must be done to generate the same matrix is RotateZ, RotateX, and finally RotateY. See also SetOrientation.

void vtkProp3D::AddOrientation | ( | float | ,

void vtkProp3D::PokeMatrix | ( | vtkMatrix4x4 * | matrix | ) |

This method modifies the vtkProp3D so that its transformation state is set to the matrix specified. The method does this by setting appropriate transformation-related ivars to initial values (i.e., not transformed), and placing the user-supplied matrix into the UserMatrix of this vtkProp3D. If the method is called again with a NULL matrix, then the original state of the vtkProp3D will be restored. This method is used to support picking and assembly structures.
