Re: [Bf-committers] It's time to get rid of cloth

Bullet's cloth system is no replacement for what Blender currently has and I'm not aware of any available library that we could use without having to do a lot of modifications to make it work. Am Di., 20. Okt. 2020 um 12:26 Uhr schrieb Brecht Van Lommel via Bf-committers : > The most important

Hi, I happen to have implemented an expression evaluator for a project I'm working on not too long ago. Here is a somewhat older WIP version: https://gist.github.com/sergof/6e6ebfa632d593ddd73801c10e5f822d For x64 I generate machine code and use a VM for other targets, so on x64 it beats all the

for mass is kilograms, I would have thought that having kilograms as the base unit would be correct. Thanks for any clarification! Andrew On 01/01/2014 4:14 AM, Sergej Reich nore...@git.blender.org wrote: Commit: ead6d397fda12d8287dff7d6a6fff6ea1948cd69 Author: Sergej Reich

Re: [Bf-committers] Some Some doubt and ideas

2013-10-19 Thread Sergej Reich
In the case of the rigid body simulation we actually already simplify things. We cannot really avoid having active and passive objects, since knowing that an object won't be simulated dynamically allows for optimizations that improve performance and stability. As for Collisions, in many ways

I think the biggest problem with testing is that only a few users actually test the daily/RC builds. Having a longer testing period would help here, but I doubt it would make a dramatic difference. Most bugs are found after release. Don't think you can do anything about that. Am Montag, den

Re: [Bf-committers] Cursor to center of mass

2012-11-21 Thread Sergej Reich
Hey Jason, currently there is a problem with n-gons when chalculating the center of mass. The issue is that we don't have a good way of calculating centroids for n-gons and just use the vertex average, so the calculated origin will drift a little when your polygons have many vertices. I'd

Re: [Bf-committers] Cursor to center of mass

2012-11-21 Thread Sergej Reich
Actually, subdivide creates n-gons in most cases (unless you use it on edge rings or the whole mesh), so it's likely to be the problem. Also here is a quick patch that adds a Cursor to Center of Mass option: http://www.pasteall.org/37435/diff Am Mi, 21. Nov, 2012 um 11:20 ,Jason Wilkins

Re: [Bf-committers] collisions detection without gameengine

There is pretty much no API for collision detection in the BulletDev branch. The only thing you can do is setting up rigid body simulations. Adding it would be possible of course, but I don't think it would be useful right now except for a couple of fringe cases. If it's needed for the diploma
