Adding multiple gradient effects

[tapaswenipathak]

Hey folks, I was using ospray for visualisation for large-scale and interactive ray-tracing of neurons. I want the output like

Do you have any sample for this? I am v. curious if ospray have gradient setting feature? I was finding like this but great if you can let me know if you have such feature, I didn't find any tickets in the repository or a sample implementation.

OSPRay is successfully used to render neurons (see e.g. Brayns).

OSPRay can also render volumetric datasets, optionally with gradient shading, see gradientShadingEnabled at http://www.ospray.org/documentation.html#volumes.
