Thanks David! I got it to work now.
Here my function creating a 2D texture from a 2-Dimensional vector, in case
it's of any use to anyone.
Code:
osg::Texture2D* createTextureLUT2D(std::vector >& data)
{
int rows = data.size();
int cols = data[0].size();
yes this is doable. You need to set the internal format to something like:
GL_RGBA32F
and the source type to float on your texture.
You might look at the OSG forest example, and its use of osg::TextureBuffer.
Basically with the forest example, its doing instancing where the transforms
are
Hi,
I'm trying to generate my own lookup table containing floats and store it in an
image, and apply it to a texture to send it to the shader. I am having issues
with getting the image to store floats though. Is there any way to do so, or am
I trying something impossible?
cheers,
Ivar
