Coarse Pixel Ray Tracing

Hi,

is it possible to create a coarsely ray tracing application with optix?

Not exactly sure what you’d like to implement, but if you can express an algorithm with ray tracing, you should be able to implement it in OptiX.
You as a developer have full control over which rays and how many are traced in your application.

Instead of tracing rays from each pixel, I would like to trace from a group of pixel (similar to the picture on the link)
