Hi !
I get strange interleaved stripes when using 3D textures in combination with auto generated mipmaps. Bug or Feature ?
Mind posting a screenshot of the problem?
Did you read back the texture values to see whether the problem lies within the visualization or the texture data itself?
N.
Ok. It was my mistake. The data I send actually gave those peculiar patterns when resampled using a cubic spline in software as well. So the result was as supposed (but I didn’t understood that first 
)
