HM - Optimize

18 Apr, 2017

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.
