Re: [osg-users] Need help fixing my atmospheric transmission shader, it's so close to working!

I should have mentioned before that only the red channel is of any importance; There is a viewer further down the pipeline that picks up the red channel values from the framebuffer so the green and blue channels don't matter at all. I just set the green and blue channels to the red channel in

[osg-users] Is it possible to get OpenGL calls as output from OSG?

Hi guys, I have what may be a little bit of an unusual question regarding usage of OpenSceneGraph. In our application we use OSG for drawing views of a dynamically created and animated model, which has so far worked out very well for us. We are now in the situation where we would like to be

[osg-users] Is it possible to get OpenGL calls as output from OSG?

Hi it is possible to achieve this in following way: render to FBO camera on provided by CAD context ( set main camera as FBO ), get texture ( there are ways to make it clean, but I just stole texture id from within inside OSG ) and apply it onto OpenGL quad I achieved rendering in Blender with

Re: [osg-users] Need help fixing my atmospheric transmission shader, it's so close to working!

Only your terrain have texture and for your trees - function call texture2D(baseTexture, gl_TexCoord[0].st) return black (0,0,0,1). Your trees have per-vertex color attribute, and your ground dont(?) (i dont know to what value it defaults). Simplest options to fix this - set 1x1 white texture

Re: [osg-users] Is a render to texture master camera critical?

Hi all, I've tried to use the main camera as RTT in several applications and it works for me as well. But I'd like to ask a couple of questions on the post process passes instead: - is there any conceptual difference between using the final ortho camera as a in-graph POST_RENDER or as a viewer's

[osg-users] Help: many cameras are rendering at the same time or one by one?

Hello, My question might be silly, but I really want to know about that. I wonder if there are many cameras (one main camera + many pre render cameras), will OSG (or grahic hardware) manage to make these cameras render one by one or at the same time? I have a programm concerning leveraging

[osg-users] [3rdparty] Maintaining osgWidget Window aspect ratio on resize

Hi, I'm starting to use osgWidget to create a GUI in a GraphicsWindowWX and am attempting to figure out how to best get an osgWidget Window to maintain a defined aspect ratio on window resize. It appears that it's not possible to do this through subclassing as the only virtual functions are

[osg-users] Best usage of function: return ref_ptr or standard ptr?

Hi, I have a function which I want to return a group, with two alternatives: Code: osg::ref_ptr osg::Group returnGroup() { osg::ref_ptr osg::Group group = new osg::Group; ... return group; } Code: osg::Group * returnGroup() { osg::Group * group = new osg::Group; ... return group; }

Re: [osg-users] Best usage of function: return ref_ptr or standard ptr?

Hi Juan, Returning a reference counted pointer is in general the safest thing to do as it ensures that the object will get deleted when it goes out of scope. A quick search of the osg-users will reveal a number of threads on the subject alternatively try the link below:
