Obi: Burst backend - josemendez - 16-01-2020
Hi there!
I've written a blog post detailing one of the most profound changes in the future of Obi: backends.
http://blog.virtualmethodstudio.com/2020/01/obi-backends-burst/
This is something that I've hinted at in the past, but there's now some tangible results that I wanted to share. In the post I also try to answer some of the questions that might arise regarding the new Burst backend.
let me know what you think!

Can't wait for it!
Obi Rope ( and of course other simulations ) finally hitting consoles!
Awesome job you're doing there!!!

Hey I'm really interested in your software and I'm curious, when you've finished porting to Burst / DOTS is it going to be compatible with the Unity Physics system built with DOTS? https://docs.unity3d.com/Packages/com.unity.physics@0.0/manual/index.html
For example, if I have some rigid bodies falling down a staircase being simulated with the DOTS version of Unity Physics can those rigid bodies also interact with Obi fluids / cloth / soft bodies ?
Also are you planning on adding any gas / smoke simulations eventually or is the plan to do this with Orbi Fluid and Shuriken particle advection ?

Not at first. However, it is on our roadmap. Supporting Unity Physics should be easy enough, all we need to do is get/set rigidbody angular/linear velocities.

Gas simulation is already possible with Obi, we have all ingredients there: buoyancy, athmospheric pressure/drag, vorticity, and advection. This is the same method used by Nvidia Flex, however it is far from being practical for general use in games. Eulerian (grid-based) methods, coupled with GPU volume rendering perform and look much better.
We want to explore vortex-particle (vorton) methods in the future, as they seem very promising for simulating gases in the CPU.

wow!!!!This is amazing work. I just tested the Obi 5.5 products (I have all of them) and I am pleasantly surprised at how great the performance is.
Great, great work! With the source available, I can integrate my own tools in a non-destructive manner.
I love it! Proud Customer and your biggest Fan. Hope to show you what I do can with these products soon.
Congrats on a job well done.
P.S. It may be a good idea to add the setup notes for Burst Backend (from the user manual) on the Unity Asset Store page.
When I first installed it, I thought Burst Backend was broken.
Disable safety checks, the jobs debugger and job leak detection is a must! It breaks with those enabled.
