This adds a curvature smoothing and intensify details properties to control
the result of the Sharpen Mesh Filter.
Curvature smoothing removes high frequency details from the precalculated
sharpen data, so the filter result has much smoother surfaces and cleaner
Default Sharpening (Curvature Smoothing 0)
Curvature Smoothing 3 iterations:
Curvature Smoothing 7 iterations:
Intensify details displaces the vertices of creases and valleys in the direction
opposite to its neighbors average, so it intensifies high frequency details
in those areas, producing more noisy and sharp shapes:
Default Sharpening (Intensify details 0):
Intensify Details 0.5 strength:
Intensify Details 1.0 strength:
Both this properties can be used in combination to achieve a good balance of
high and low frequency details depending on the shape and the desired result.
