Mipmapping in Optix

Interface for mipmapping has been present in Optix since v1.0, and the doc states that it will be implemented at some point.

I was wondering is it known when will this happen?

I need mipmapping for rendering, it’s not very urgent but the lack of it produces a lot of aliasing.

Would it be worth the trouble implementing it manualy, performance being what it is in ray tracing? I assume that the overhead would be quite big compared to the hardware solution that will come in future releases of optix.

You would need to implement ray differentials in your renderer for that anyway, so you could start doing that today and look at the example inside the OptiX SDK called rayDifferentials which shows one way to implement mipmapping manually.
