Documentation
The tessellation step is the entry point to the
polygonal representation which permits to display the model when
coming from a CAD file.
This step is very important for the final quality of
the model.
Here are some examples and advices on the use of
tessellation parameters:
Reduce the « max Sag »
value make the mesh less rough and more realistic.
Adjust the « max Angle »
parameter keep enough polygons in high curvature areas whose radius
is lower than the « max Sag » value :
fillets and chamfers for example.
In the above example, the « max Angle »
parameter has improved fillets precision by adding a row of elements
without increasing polygons number of the yellow piece contour.
For a rendering usage, we don’t advice to use
the « max Lengh » parameter. This
parameter inscreases the polygons count without improving the visual
aspect.
