Camera Occlusion Culling for Micro Displacement in Blender on Vesta @KaiKostack

Uploaded September 2016 | Updated September 2026, 7 hours ago

Here is a quick look behind the scenes of my Vesta asteroid video made in Blender. I show how my camera based occlusion culling works for the new micro displacement feature which by default subdivides everything within a certain distance of the camera. To avoid that I basically made a cone-shaped array of planes parented to the camera which masks out geometry not touched by the cone by using a Vertex Weight Proximity modifier and a Mask modifier. I have added also an extra mask object for the backside of the asteroid. It's not exactly rocket science but saves huge amounts of memory and render time without a noticeable difference for the render result.

$Prototype Fracture Engine for Arbitrary Deformed Cells in Blender Blenders demolition guy and the fracture guy put some thoughts together as we wanted to get rid of the unnatural look of Voronoi cell fracturing. So I came up with a prototype implementation you can see in this video. All objects shown in this video are solid and watertight, they do not include any non-manifold geometry, and there are also no air bubbles as the shards fit together perfectly. Good to go for rigid body simulation. But this is only the first step... Stay tuned. http://blenderartists.org/forum/showthread.php?343637-Custom-Build-Blender-Fracture-Modifier$
