[osg-users] osgDB::readNodeFile fails for IVE files, works in osgviewer

Hi, I am in the process of porting a program using OSG developed in Windows to Linux (Ubuntu 10.04), and I am not able to get the program to load my IVE files that were generated in Windows. However, the osgviewer program is able to open the files without problem, but my program won't. Every

Re: [osg-users] Intersecting volumes and terrain

Hi, I haven't done this myself, but I believe the PolytopeIntersector will give you a list of points you are after. You need to define the planes that make up your volume and then use an IntersectionVisitor with the PolytopeIntersector to intersect agains your terrain. From there you can retrie

[osg-users] changing the up direction of the SphericalManiuplator

I have been using the SphericalManipulator and it works really well for my application. One thing I would like to do is change which direction is up. The default is Z == up. Sometimes I want X to be up. If I understand the code, I need to make fairly extensive modif

Hi, I generate terrain using VPB and need to implement intersection lines like on attached picture (green lines that shows intersecton between cone and terrain). Could someone please give me a hint how to make it using osg? Thank you! Cheers, Roman -- Read this topic online her

Re: [osg-users] Stencil buffer and FRAMEBUFFER_INCOMPLETE_ATTACHMENT_EXT

Hi JP, As soon as I attach an image, OSG crashes on me. The problem arises in FrameBufferObject::Pimpl::Pimpl. Code: // This code crashes osg::Texture2D *texture = new osg::Texture2D(); texture->setTextureSize(1024, 1024); texture->setInternalFormat(GL_DEPTH24_ST

Hello Lee, I think fork is more sharp :). Ha, I am sorry for the wrong words. Hehe, it's fine, I didn't mean to make fun of your wording, it was just a funny slip. :-) Actually, I found that the 3rd part lib I download from osg office site is not include the libpng(d).dll file. It might

Re: [osg-users] Threading issues with osgText

Hi Björn, If setting the DataVariance to DYNAMIC doesn't fix the crash then it looks likely that the problem is elsewhere. I don't have an answer to what this might be, debugging problems like this is hard when you have the crashing app in front of you, without this it's just a case of educated g

Hi Robert et al, I have already set DYNAMIC data variance to both the osgText::Text and the osg::Geode which holds the text. Crashes anyway. I have tried to replicate the error in a more simple environment than our production software. But no luck with getting crashes with the simple one. :/ T

Hi Mahendra , osgimage::data() returns an (unsigned char *) so the array indexing only steps one byte. use ((float *)dirImage->data(i))[0] = pos.x();//same effect ((float *)dirImage->data(i))[1] = pos.y();//different effect ((float *)dirImage->data(i))[2] = pos.z(); Laurens. On 10/15/2010 10:

Re: [osg-users] Stencil buffer and FRAMEBUFFER_INCOMPLETE_ATTACHMENT_EXT

Hi Fred, we've also encountered cases (float formats) where we need to call: void setInternalTextureFormat(GLint internalFormat); after allocateImage in the case of using Images to read back data. If you look at allocateImage code, you'll see why. Can you check if this works for you without
