Comparing Blender's Cell Fracture Add-on with My 'Real-Time Fracture' Add-on #Blender #addon

Made with Blender
Hello everyone! I’m excited to share that I’ve achieved excellent results with my add-on, “Real-time Fracture.” It is 12 times faster than Blender’s default “Cell Fracture,” even when creating more cells. While Blender’s “Cell Fracture” takes 3.6 minutes to generate 2,999 cells, my add-on “Real-time Fracture” can create 5,230 cells in just 18 seconds.

The add-on is not yet fully completed; I am currently working on the UI. I’ll be sharing it with you very soon. I look forward to your feedback. Thank you!

Hello, the speed gain seems nice but the example in the video is not really fair to either methods, the vanilla one has a much tighter distribution in parts size and volume, while your method has much bigger parts and much thinner parts so if you compare them both side-to-side they look pretty different, almost like the center of the sphere and the exterior of the sphere are different materials, so I’m not that surprised that the computation time is different.

A look at the UI would be nice indeed, since parameters and customization are very important when running simulations.

Also, if it takes 18 seconds it’s not real time, even if you put it inside quotes ^^ Real time means you almost don’t notice your computer is running the simulation. If you plan on distributing this as a paid product you might want to emphasize this so you don’t get upset customer feedback.

Cheers :slight_smile:

Hello, the fact that the piece sizes are different from cell fracture in my addon is actually related to my adjustments. In other words, even with similar surface structure, my addon is much faster in the tests I have done. In cell fracture, the spaces between the cells are generally irregular and sometimes there are too many spaces, while the spaces in my addon are more regular and smaller. Right now, my addon with 5000 cells does it in 18 seconds, but the addon is not finished yet, my goal is to reach 3 seconds for 5000 pieces. By the way, when I do fragmentation for plane(2d), it takes 10 seconds for 1 million cells. I will work on the UI, I aim to make it as clear and have enough control as possible. When I reach the target speed, I will make new shares and comparisons.Here is 1mil cells:)


Another point is that cell fracture creates too much space, so at the beginning of the simulation the pieces start to separate from each other and fall apart. My addon also falls apart when it hits the ground. There is no constraint in both simulations.
