the entity center to the corners of the BBox. The entity can move in any direction May the standard manipulators are a good start. Some of them perform collsion detection. A number of LOS-intersectors will do the job, too ;-) Cheers Sebastian On Mon, Mar 13, 2017 at 9:41 PM, Sebastian

Re: [osg-users] bounding box collisions (without osgbullet)

Hi Nick, basically this is not an easy task. What exactly do you expect as a collision result? I've implemented a triangle-box collision with MTD (minimal transform distance = vector describing how to push the box to get it exactly away from the colliding triangle). OSG has all the math

Re: [osg-users] Displaying Geode Bounding Box

Hi Sam, Hi All, Is there a simple way to display the bounding box of Geode or Geometry? Or will I have to write up something to do it? osgWorks[1] might yield something ( osgwbvv) [1] https://github.com/mccdo/osgworks Cheers Sebastian Thanks, Sam

Re: [osg-users] Paint splashes / How do I decal?

Hi, Ok wow but what does it mean? Screen space sounds evil. I can't really get any hard results on Google for it. Basically the first hit gives an implementation guideline and links to the other techniques I've mentioned:

Re: [osg-users] Paint splashes / How do I decal?

Hi Johny And why not a geometry approach? You can totally use 3d models, but that might induce z-fighting, sorting problems etc. Another option is of course using a world-space spanning texture per object-instance and managing drawing to this texture at the right spots. This isn't very

Re: [osg-users] Paint splashes / How do I decal?

Hi Johny, Here's Johny! I'd like to know how to pick a 3d point in my model onto which a decal will nearly wrap itself around to. Am I using the right word here, or does Open Scene Graph not have this feature? Before I'm rigging my app with a custom decal, I'd like to know what's available,

Re: [osg-users] Height of terrain

Hi Bhanu, We surely cannot help you without the data you use. But try to use a Z-Value that is actually _above_ the the terrain might help. Cheers Sebastian Hi, I tried with following expression double X = 8489499, Y = 1115164, Z = 0; uble height =
