PM - Optimize

Fluid meshes often consist of several hundred thousand or even millions of polygons. For fast display and rendering inside your 3D application this fact sometimes is a real performance killer. Therefore, RealFlow provides effective methods to optimize your meshes and reduce the number of polygons. Especially with view dependent scenes, a reduction of polygons is a perfect way to decrease rendering times. The parameters of the "Optimize" panel support the "Interactive Meshing" feature.

Optimize

This entry provides three options: “No”, “Curvature” and “Camera”. “No”, of course, disables any optimization. Both of the others unlock further settings to control the mesh quality. The “Camera” option depends on the current view. Areas closer to the camera have higher resolution, while distant parts show reduced quality. “Curvature” analyses the mesh’s geometry and polygons in flat areas will be removed first. Higher values can be used to delete polygons from areas with more curvature, too.

@ Optimize Camera

Before the mesh engine can calculate the mesh based on a certain view, a camera has to be selected. This camera can also be animated to create a dynamic view-dependent mesh. It is also possible to attach imported cameras from other 3D programs.

@ 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. The area of highest resolution is always next to the camera. "@ Distance is measured in metres [m].
