[osg-users] glow

Hi Community, has anyone experimented with glow effect? I have spent some time with research and I found only implementation as image post processing that requires having your scene rendered into a frame buffer. I dont like this way though, so I am looking for some alternative. Please let me

[osg-users] PagedLod : how to change priority for some nodes

Hi all, Maybe my last question about PagedLod... I hope ;-) Starting my application, databasePager start to load thousand of PagedLod in my scene. In this list, I would like to make some PagedLods nodes being loaded before the rest of the scene. (because thousands of node take sometimes

Hi, We used this approach for rendering a 2D scene using the painters algorithm (i.e. render back to front according to our own order definition). I have included the most relevent code snippets. No comments on their quality please ; ). 1) Added a 'user data' object (which contains the

Re: [osg-users] PagedLod : how to change priority for some nodes

Hi Vincent, PagedLOD has a prority offset and scale per child that allows you to modify the priority computed from the distance range. The PagedLOD methods of interest are: void setPriorityOffset(unsigned int childNo, float priorityOffset) { expandPerRangeDataTo(childNo);

[osg-users] How to thange color of static Geometry using Switch and StateSet?

Hi, i am OSG newbie. and i'm working with Java project which uses JavaOSG binding by NoodleGlue. about the problem: 1. I have static Geode with one drawable (geometry to draw Icosahedron). These geodes represents some specific points (lets name it diamonds) in scene (may be more than 100).

Hi JP, thx for the quick response. Yes, there is a ClearNode, but I'm not sure, if it makes much sense using it, because I think I will need a camera anyway to specify which colorbuffer exactly I want to clear. As far as I know I can only call setDrawBuffer() on a camera object, or is there

Hi Trajce, I always use this kind of glow. Glow tipically is a post process effect, but If you find another way tell me! :). I have implemented some filtering system with shaders based on OSG so you can concantenate some filters (gaussian, radial, etc) to the final image. If you want I could

Hi JP, what I meant is, that I need to call glDrawBuffer (or setDrawBuffer in OSG) to select the buffer that I want to clear. Sorry, that I did not make it clear. The following OpenGL code example shows what I want to realize in OSG: Code: //for each frame do id = id mod 2; // Id is switched

Re: [osg-users] How to thange color of static Geometry using Switch and StateSet?

With the situation you describe, in which the Geometry is shared, the best way to change color would be with a unique BlendColor on the MatrixTransform's StateSet. You'll need to enable blending for this, and set the blend function to reference the blend color and zero the dest color, like
