Hi Dave,
sounds good. Is there a particular reason not to port the softpipe anisotropic filter implementation (or from swrast, they are almost identical)? Wouldn’t that be easier to implement as it is based on the gallium infrastructure already?

I was considering porting code from swiftshader, maybe I can bump it up the priority list. Dave.

We are still actively using classical OSMesa for high quality rendering of still images in a headless environment with no GPU support (server-based rendering on windows and linux) Unfortunately, none of the alternative software renderers provide all the features that we require, which is antialiasing and anisotropic filtering. The current state is (correct me if I'm wrong) * softpipe: anisotropic filtering is supported, no antialiasing * llvmpipe: no anisotropic filtering, has MSAA * openswr: no anisotropic filtering, has MSAA, no OSMesa interface (?) We had hoped that classical OSMesa is only removed when there is a full replacement after the discussions in 2016 when OSMesa was about to be removed for the first time https://lists.freedesktop.org/archives/mesa-dev/2016-March/109665.html https://lists.freedesktop.org/archives/mesa-users/2016-March/001132.html and the commit that reverted the removal http://cgit.freedesktop.org/mesa/mesa/commit/?id=9601815b4be886f4d92bf74916de98f3bdb7275c Are there any plans to enhance the renderers so that at least one of them is providing both anisotropic filtering and antialiasing? As far as I know, anisotropic texture filtering is also one of the OpenGL 4.6 requirements. In 2016 I was told that there are only very few developers involved in llvmpipe and that chances are not high that someone is going to port the softpipe anisotropic filtering implementation as llvmpipe is much more complex. Is there any change in that situation?
