[vtkusers] How to draw rectangles using CDC in vtkMFCWindow

[Bryn Lloyd]

Hi

I think one way to achieve this, would be to pack the code

CPaintDC dc(this);
dc.rectangle(....);

into a subclass of vtkProp. Override the function RenderOpaqueGeometry or
maybe RenderOverlay and place your code inside.

Then add this prop (== actor) to the vtkRenderer.


Have a look at this post:

Good luck
Bryn
