GPU-based draft analysis: with aid of mordern GPUs, traditional draft analysis can be accelerated by more than 20 times and performed in real-time by dragging the triad control to find faces need to be drafted (in gradual transition color from green to blue) on a solid model.


GPU-based undercut analysis: with aid of mordern GPUs, undercut analysis can be performed in real-time by dragging the triad control to find the undercut regions (red) on a solid model with respect to a pulling direction.


GPU-based parting-line analysis: with aid of mordern GPUs, parting-line analysis can be performed in real-time by dragging the triad control to the find the parting-line regions (purple) on a solid model with respect to a pulling direction.
