HM - 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.
