Hi Wyatt,
Is this what you are referring to?
if (withBaseTexture)
{
scene->getOrCreateStateSet()->setTextureAttributeAndModes( 0,
new osg::Texture2D(osgDB::readImageFile("Images/lz.rgb")),
osg::StateAttribute::ON);
}
Nope, this:
{
// fake texture for baseTexture, add a fake texture
// we support by default at least one texture layer
// without this fake texture we can not support
// textured and not textured scene
// TODO: at the moment the PSSM supports just one texture
layer in the GLSL shader, multitexture are
// not yet supported !
osg::Image* image = new osg::Image;
// allocate the image data, noPixels x 1 x 1 with 4 rgba
floats - equivilant to a Vec4!
int noPixels = 1;
image->allocateImage(noPixels,1,1,GL_RGBA,GL_FLOAT);
image->setInternalTextureFormat(GL_RGBA);
// fill in the image data.
osg::Vec4* dataPtr = (osg::Vec4*)image->data();
osg::Vec4 color(1,1,1,1);
*dataPtr = color;
// make fake texture
osg::Texture2D* fakeTex = new osg::Texture2D;
fakeTex->setWrap(osg::Texture2D::WRAP_S,osg::Texture2D::CLAMP_TO_EDGE);
fakeTex->setWrap(osg::Texture2D::WRAP_T,osg::Texture2D::CLAMP_TO_EDGE);
fakeTex->setFilter(osg::Texture2D::MIN_FILTER,osg::Texture2D::LINEAR);
fakeTex->setFilter(osg::Texture2D::MAG_FILTER,osg::Texture2D::LINEAR);
fakeTex->setImage(image);
// add fake texture
_stateset->setTextureAttribute(_baseTextureUnit,fakeTex,osg::StateAttribute::ON);
_stateset->setTextureMode(_baseTextureUnit,GL_TEXTURE_2D,osg::StateAttribute::ON);
_stateset->setTextureMode(_baseTextureUnit,GL_TEXTURE_3D,osg::StateAttribute::OFF);
#if !defined(OSG_GLES1_AVAILABLE) &&
!defined(OSG_GLES2_AVAILABLE)
_stateset->setTextureMode(_baseTextureUnit,GL_TEXTURE_1D,osg::StateAttribute::OFF);
#endif
}
(sorry for the formatting, search for "fakeTex" in your sources and you
should see it)
