Hi, Hi,Actually Iam Working on the placing of Buildings,Trees etc on the Terrain.Buildings are in .shp format,Terrain is in .flt format,Positioning of the Buildings is adjusted by the ig data which is in the format of pitch,rolling and Heading.Can anyone help me how to load the buildings/trees

Re: [osg-users] Visualization of billboards depending on pre-conditions

Hi, But why not do occlusion query every frame? Is there any problem? because multi-pass depth test should also be done every frame. -- Cheers, --- TianZJ At 2017-01-08 22:46:27, "Hartwig Wiesmann" wrote: >Hi Tian, > >an occlusion query is

Re: [osg-users] Visualization of billboards depending on pre-conditions

Hi Tian, an occlusion query is difficult because the scene is continuously changing. Ad Robert: drawing the sign itself is not the issue. I would either like to see the sign completely or not at all. I will do some tests with multi-passes. Thank you! Cheers, Hartwig -- Read

Re: [osg-users] System requirements for OpenSceneGraph

Hi Nikita, If you want to help finding the cause for the bug in master you can run a git bisect. git bisect will use a binary search pattern and give you commits to test on your PC, usually this takes about 10 steps and you'll arrive at the problem commit. http://webchick.net/node/99 Once

Re: [osg-users] Visualization of billboards depending on pre-conditions

Hi, Occlusion query is a better idea, especially for rendering many billboards. About the performance, here is a discussion, http://gamedev.stackexchange.com/questions/118651/opengl-occlusion-culling-huge-performance-drop which points out that calling all the queries together

Re: [osg-users] Visualization of billboards depending on pre-conditions

Hi Hartwig, You can use the occlussion query extension to do the test but the round trip to the GPU and back be prohibitive for real-time performance. This is even before you start having to do a second pass to decide whether to render or not the signs. Do you really need to do this? It would

Re: [osg-users] Visual flicker when using multi-pass technique, related to frustum?

Hi Hartwig, In principle what you are doing should work, the project and modelview matrix by default should be inherited down correctly - there shouldn't be a frame delay. The only thing that looks like it could cause problem is that you switch off the compute near/far for the slave camera but

Re: [osg-users] Visualization of billboards depending on pre-conditions

Hi, yes, this is an idea. But as a first step I have to estimate a suitable area location and size for the passes. I do not like the idea of ray checking because I think that it is rather slow. Especially when I have to do the checks for a lot of billboards. Thank you! Cheers, Hartwig
