Examples of Coarsening
Examples of Coarsening
The images below show a model with approximately 1,000,000 shell elements in its raw state, and illustrate how progressively harsher coarsening reduces the image quality but speeds up the graphics.
This is the original image. Time to animate a frame on representative hardware: approx 95mS / frame

This is the same model using coarsening. Some "speckling" is evident and the overlay is poking through in a few places. However time to animate this model is now reduced to about 50mS / frame.

Finally here is the same model using coarsening. More artefacts are visible, and the large patches are clearly evident on the glass panels. However time to animate now approx 30mS / frame , which is over 3x as fast as the original model above.
