Raycast touching object? Passing through walls...
Hi, I use raycasting in order to 'floodfill' a space with objects. I do a simple raytest from A to B: btVector3 rayStart( XXX ); btVector3 rayEnd( XXX ); btCollisionWorld::ClosestRayResultCallback rayCallback( rayStart, rayEnd ); rayCallback.m_collisionFilterMask = a_filterMask; // short int a_filte...

Re: rayTest from multiple threads? Is it safe?
thanks c6, ill look for it.
of course Im not doing ANY step/update from ANY thread during multi-threaded casting.

thats not good
Maybe Erwin can confirm?
At least without doing any world step or world modification, it should be thread safe.
Thanks

rayTest from multiple threads? Is it safe?
Hi all, I want to do raycasts from many threads simultaneously. While doing so, NO 'world update' will happen and no changes on any object. (maybe some debugdraw but I can eliminate that too if it helps). Is this (multi-threaded raycasting on a single world) thread-safe? Will I get the correct ray h...

Test visibility between 'objects' (solids and transparents?)
Hello, Let me describe what I need to do: in a very *simplified* form! http://i49.tinypic.com/3538fhk.png In a 2d software that I have I can divide the space in boxes and I can check the inter-visibility between the boxes. The boxes represent the open space and the "black/empty" are solid ...
