Black Hole vs. Earth @KaiKostack

Uploaded August 2020 | Updated September 2026, 9 hours ago

This is a path-traced black hole based on the gravitational lensing effect made in Blender. Earth has been added merely for entertainment purposes, it's not a scientific simulation. Enjoy!

Technically the black hole consists of stacked spherical meshes with different radii to serve as volumetric ray intersection samples that would modify the light path depending on the spatial force field strength. To keep render times low a maximum of 40 transmission bounces per pixel were targeted at the cost of some accuracy. The video took two weeks to render on a GTX 1080.

Simulated in Blender + Fracture Modifier, rendered with Cycles. Watch in 4K to reduce compression artifacts from YouTube.

Driving Car Crash Simulation Development Reel (BCB, Fracture Modifier)

$Brickify - Bricks, Buildings, Blender, Bullet - 3D Destruction Physics Prototype brick-shape fracture method for Blender Fracture Modifier. Brickify took 3 min to fracture. The 50 steps/s simulation took 5 min to simulate. Doubling the steps count means doubling the simulation time while increasing accuracy. Rendering took 2 days. Enjoy!

House of Cards of Bridges (Collapse & Destruction)

$Stanford Bunny tortured in Blender (Arbitrary Deformed Cell Fracture 2) This is a second video about the new fracture method w.i.p. showing off the topology of the generated shard geometry. 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. However, to work efficiently together with rigid body simulation this requires also some improved shape type alongside the classical Convex Hull. Hierarchical Approximate Convex Decomposition (HACD) by Khaled Mamou seems as the way to go.

Bridge Collapse - Fatigue Failure (Fracture Modifier, Blender)

$Dom-Ino House Exposed to Earthquake using Dynamic Fracture This video shows various simulations of a classic steel reinforced concrete building design in a scenario of strong seismic activity. The simulation is done in Blender with my Bullet engine based Dynamic Fracture system. Now it is working together with rigid body constraints, thus making it compatible with prefracturing based systems like the fracture modifier and the Bullet Constraints Tools addon. What is this good for, you ask? Well, since Dynamic Fracture always attempts to fracture one object as a whole it can lead to undesired results when fracturing huge structures like complex buildings merged into one mesh. Now one can use a mix of both methods. Edit: You can do all this now with Fracture Modifier and Bullet Constraints Builder add-on which can also generate earthquake motion.
