Hello, I'm trying to create a Texture2DArray. My textures are uchar images with size (texWidth, 256), single channel. The combination of texture internalFormat and pixelFormat with pixelType is not working. I use GL_R8UI for internalFormat, GL_RED_INTEGER for pixelFormat and GL_UNSIGNED_BYTE for type. This yields the following error when I try to render my scene:
*Warning: detected OpenGL error 'invalid enumerant' at after RenderBin::draw(..)* However, if I use GL_LUMINANCE for internalFormat and also GL_LUMINANCE for pixelFormat, I get no errors but my textures are not correctly sized. WHat formats should I use here? This is my code: osg::ref_ptr<osg::Texture2DArray> texture = new osg::Texture2DArray; texture->setFilter(osg::Texture2DArray::MIN_FILTER, osg::Texture2DArray::LINEAR); texture->setFilter(osg::Texture2DArray::MAG_FILTER, osg::Texture2DArray::LINEAR); texture->setWrap(osg::Texture2DArray::WRAP_R, osg::Texture2DArray::REPEAT); texture->setInternalFormat(*textureFormat()*); // Add some images as follows: for (...) { osg::Image* image = new osg::Image; image->setImage(texWidth, 256, 1, *textureFormat(), pixelFormat(), type(),* dataPtr); texture->setImage(i, image); } I am using: textureFormat() = GL_R8UI; pixelFormat() = GL_RED_INTEGER; type() = GL_UNSIGNED_BYTE
