the problem description:
attached image shows the situation, when animated moving of object along the x-axis (po_Context->SetLocation (poAISShape, o_Trafo);) leads to unwanted effect of clipping. V3d_View object contains no clipping planes. when the scene is redrawn (it is enough to move the cursor above the object to force the outlines redrawing), the clipping disappears.
thanks for any advice.
