PL - 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.
• “Camera” depends on the current view. Areas closer to the camera have higher resolution, while distant parts show reduced quality.
• “Curvature” removes polygons in flat areas.

Merge Iterations

This parameter specifies the number of optimization cycles and depends on “Ite Threshold”. With each iteration pass, RealFlow tries to remove more polygons, but always related to “Ite Threshold”. With large “Merge Iterations” the mesh will shrink.

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.

Ite Threshold

This parameter is closely related to “Merge Iterations” and can be seen as a trigger. Higher values are used to remove more polygons, but also decrease the mesh’s quality. The standard setting is a good starting point.

Face subdivision

When active, new faces will be added to the mesh, creating a smoother look. After this process, some parts of the mesh might show a characteristic pattern. We recommend applying filters and instead of “Face subdivision”.

Sub Threshold

You can specify a certain trigger value to start the process of subdividing a mesh’s faces, but in most cases, this value has no influence on the final result.
