PM - Optimize

This section provides effective methods to reduce the number of polygons. Especially with view dependent scenes, a reduction of polygons is a perfect way to decrease render times.

Optimize

This entry provides three options:

“No” disables any optimization.
“Curvature” removes polygons in flat areas.
“Camera” depends on the current view. Areas closer to the camera have higher resolution, while distant parts show reduced quality.

Min Angle

The range of this parameter is between 0 and 90. Values close to

90 degrees will remove vertices and faces that are almost coplanar, effectively reducing the amount of faces in areas where we don't have detail
0 degrees will remove vertices and faces also in areas with detail changing the overall shape of the object.

Max Steps

Specify how often the optimization will be applied:

With every step the number of vertices and faces is being decreased.
The new vertices and faces might also be optimized further during the following steps.

Optimize camera

Here you can select a camera for use with the “Camera” option under “Optimize”. This camera can also be animated to create a dynamic view-dependent mesh.

Distance

This value represents the distance between the camera and the area where the first polygons will be removed. With growing distance (= higher values) the number of polygons decreases. "Distance” is measured in metres.
