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 ...
