[osg-users] Shader Problem

Hi all, Are there any ways to remove the shader during runtime? I've tried the removeShader function but the effect of the shader is still applied to my models (e.g tank) i.e. the appearance of the models do not go back to the state before shader is applied. Regards,Cg

Hi Pecoraro thank to spot the bug please send your submissions on osg-submissions the next time. after review the original code, at line Optimizer.cpp:1561 lod-getNumRanges() is used to know how many iteration will be done in the for loop, and getNumRanges have to be equal to getNumChild, so

[osg-users] Viewer Hanging Problem (Without the main viewer loop)

Re: [osg-users] Shader Problem

hi CG when you remove a shader, osg::Program need to be relinked. this is done by osgUtil::GLObjectVisitor in osgViewer::Renderer::draw method. So this seem can be done at runtime. Which OSG version did you use ? Did you use osgViewer ? David Callu 2008/6/12 CG [EMAIL PROTECTED]: Hi all,

Hello, I would like to create an effect (using osgFX) which render the depth buffer. I'm using a RTT and then apply the texture to the object but i'm having some problem for mapping correctly the texture on the object (see capture in attachment). My RTT camera must be similar to my viewer camera,

Hello again, I figured out that there is no hung OSG viewer but a WM_KEYDOWN message processed by the OSG's WindowProc. If you put an OSG Viewer in an MFC window, even if you don't activate OSG manipulators, OSG's Window Procedure is still active and handles messages before your

Hi David, The tiles in the PagedLOD don't match up perfectly in general. osgTerrain gets them really close, but sometimes you'll see the gaps like you pointed out in your image. osgTerrain uses a skirt around each tile to hide those gaps. If the default skirt is not working out for you, you can

Loading a large number of images all at once might be overloading your memory capacity. Even if you can fit all of the images in main memory at once, doing it this way does not scale very well. Google Earth does it this way and it chokes hard when loading larger animations. Remember that even if
