What is Culling?

Culling is a computer graphical process used to improve rendering performance by discarding unnecessary vertices or faces (polygons) based on visibility before they are processed further. Beside improved rendering performance, culling may also be used to eliminate clipping issues between Shapes and Deformables.

Use in Popul8

The user will be given the option to create a Culling asset for any Deformable by right-clicking on it, and select Create > Culling. The Culling Asset will display a number of user-configurable settings:

• Culling type: vertex culling / face culling.
• Other Deformables: list of other deformables to consider for culling in conjunction with the Deformable of interest. Optimized culling data will be computed for all deformable combinations.

After editing the settings, the user will click on Apply Changes to trigger the computation of culls.
