[osg-users] Compiling without Qt? Was Re: Compiling on Snow Leopard, problem with GDAL

Hi, Actually, it was enough to set the architecture to just x86_64 and it compiles 2.8.3. But when I tried to compile 2.9.8, at compiling osgQt it complains for the same reason, Qt is 32 bits. As at least currently I am not using Qt with OSG, I'd like to compile OSG without Qt support. In the

[osg-users] 1-bit texture for shader

Hello I'm using a shader to draw a texture of 32-bit floating point data. That's working fine, but I need to pass through whether a given texel should be visible or not. I'm trying to create a 1-bit texture, like this: int internalFormat = GL_RED; int pixelFormat = GL_RED; int

Hi Sanat, 1) Since I am trying to use models in my simulation, I wouldn't want to spend too much time on creating rigged+animated models in blender/3ds etc. I would want to buy/use already rigged+animated models. I did a bit of looking around and didn't find a good source of models with

Hi Alejandro, How is the right way to compile OSG without Qt? On my Windows machine at least, if I set QT_QMAKE_EXECUTABLE to empty and do configure in CMake, it will set all the Qt variables to *_NOTFOUND and when I generate it won't include the osgQt library in the build. Perhaps that

Re: [osg-users] 1-bit texture for shader

Hi! You can use 8-bit mask texture filled with zeros and 0xFF's (like your bitmask). Then just multiply texels of source texture and mask texture. Texture format could be GL_ALPHA and internal format - GL_ALPHA8. ___ osg-users mailing list
