- Parameters
- 
  
    | film | film (i.e. image) defining the pixel resolution |  | rotation | rotation in degrees of the camera in world space (applied in x, y, z order) |  | translation | translation of the camera in world-space units, applied after rotation |  | focalLength | focal length of the camera in mm (the default of 50mm corresponds to Houdini's default camera) |  | aperture | width in mm of the frame, i.e., the visible field (the default 41.2136 mm corresponds to Houdini's default camera) |  | nearPlane | depth of the near clipping plane in world-space units |  | farPlane | depth of the far clipping plane in world-space units |  
 
If no rotation or translation is provided, the camera is placed at (0,0,0) in world space and points in the direction of the negative z axis.

◆ lookAt()
Rotate the camera so its negative z-axis points at xyz and its y axis is in the plane of the xyz and up vectors. In other words the camera will look at xyz and use up as the horizontal direction.
