vtkRENDERWINDOW Procedure

Renders a VTK window.

Usage

vtkRENDERWINDOW[, window_index]

Input Parameters

window_index—(optional) An integer specifying the index of an existing VTK window. If omitted, the current window is used.

Keywords

None.

Discussion

Call this procedure after all objects (lights, cameras, surfaces, polygon meshes, etc.) have been added to the window. This routine starts the rendering process and creates the initial rendered scene. You need to call this procedure only if you used the Norender keyword with the vtkWINDOW Procedure, or if you are making low-level calls to VTK using vtkCOMMAND.
