[osg-users] ShadowMap + Other shaders (bump, specular, etc) example???

Hi, Does anybody have any example where I could find any solution to combine shadow maps and other shaders, specially bump mapping?? Thanks! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=58876#58876

Re: [osg-users] ShadowMap + Other shaders (bump, specular, etc) example???

Hi Jaime, yes, I have such an example. If you have the bump mapping GLSL code ready you can mix it with the shadow map shaders and set it to your shadow mapping technique - there are methods like setShadowVertexShader/setShadowFragmentShader/setMainVertexShader/setMainFragmentShader Nick On

Re: [osg-users] ShadowMap + Other shaders (bump, specular, etc) example???

Thanks for your response Nick. Yes, I have my bump shader. But I don't know how to combine. Please, could you give me an example with code?? Thanks! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=58878#58878

Re: [osg-users] ShadowMap + Other shaders (bump, specular, etc) example???

Hi. Here's my example: https://bitbucket.org/kornerr/osg-deferred-shading ( http://youtu.be/AjWOSuLxZ68 ) It has 2 implementaions: plain OSG and EffectCompositor (not part of OSG). The basic idea behind my implementation is to: * render the shadow only information to texture; * do all the rest

[osg-users] osgviewerQt example - 3D disappears if Viewer height is zero

Hi, in my Qt application I'm experiencing some issues when the viewer is reduced to 0 height. I reduce the viewer size to 0 height then I increase its height again and when I try to interactively rotate the (no more visible - see below) scene with mouse (through a trackabll manipulator) I get

Re: [osg-users] Odd Font/Text issue

Hi Josh, A Quadro shouldn't have problems with texture subloading, NVidia drivers are normally pretty good, but perhaps the one you are using is not great. Trying other machines even if they aren't your target would help as a sanity test. One thing you could try is to disable the subloading

Re: [osg-users] Scrolling a texture in runtime

H Ahmed, There are various ways to scroll textures: 1) manipulate the texture coordinates on geometry, 2) modify the texture coordinates via an OpenGL texture matrix - using osg::TexMat (wrapper to glTexMat) state attribute attached to the StateSet above the subgraph you want to scroll, 3) use

Re: [osg-users] osgviewerQt example - 3D disappears if Viewer height is zero

Hi Gianni, The issue sounds vaguely familiar, but I'm afraid I can't recall all details off the top of my head, or whether it was osgQt specific even. My guess it'll be an issue with the camera projection matrix being scaled to 0,0 to fit to zero sized viewport and then once an attempt to

Re: [osg-users] [vpb] VPB cannot dispatch task files dynamicly on android

HI ZL, I am bit confused, VPB is an offline tool used on desktop or server machines to build a database. It's not a piece of software ever written to run on Android, it's never been ported, and I really can't see any value in this either. If you want to do this under Android then give up now,

Re: [osg-users] [vpb] Windows and weird error messages

Hi Keith, We've had problems with VisualStudio's buggy compiler when it comes to handling valid C++ relating to streams. It's kinda crap but that's just what we have to put with. Is the problem you are having with the svn/trunk version of VPB or one of the dev releases? There is chance that

Re: [osg-users] How to modify projection matrix from (own) CameraManipulator directly

HI Martin, The svn/trunk and OSG-3.2 versions of the OSG have a CameraManipulator::updateCamera(Camera) method that by default just sets the Camera's ViewMatrix, but you can modify other parameters in your CameraManipulator subclass. Robert. On 9 April 2014 15:41, Martin Siggel

Re: [osg-users] [vpb] Windows and weird error messages

Hi Keith, Please search the forum/mailing list. This topic has been raised quite a few times. Please add /FORCE:Multiple to your linker options for the complaining module/linking application. @Robert, I think the option might be added to the CMakeList to fix this at least for VPB. I

Re: [osg-users] osgviewerQt example - 3D disappears if Viewer height is zero

Hi Robert, If I set the camera projection resize policy to FIXED then I don't get the bunch of NAN dump and the does not disappears. Anyway I tried with the osgviewer application calling it with --window option and even if the camera projection resize polici is set to HORIZONTAL, it works fine

Re: [osg-users] Odd Font/Text issue

Thanks. The environment variable doesn't change the results, but the latter suggestion (font-setMinFilterHint(osg::Texture::LINEAR)) does. The text is all displayed, albeit at a lower visual quality (which I guess should be expected). Upon further digging, the application wasn't using the
