Support for POVRay-like scripts to render a whole scene? #505

Closed heriberto-delgado closed 6 months ago

heriberto-delgado commented 2 years ago

This is an actual, real need I have in a process performed by the company I work for. We use POVRay to generate some renderings, but noticed that the tool performs way too slow for our needs - understandably so, since it is a CPU-only tool. When asked whether the tool will ever get GPU or any kind of acceleration support, they outright rejected the request.

I just discovered this today, and my first impression is it looks like a promising POVRay replacement for our internal processing - the only thing I would like to confirm is, will we ever be able to generate a script (any script - there is no need for it to be in POVRay language or anything) with the required scene and tell this lib / tool, in one single step, to render it? Or is this something we need to tackle in a program using the lib?

I'd say yes, but rather by using OSPRay Studio (on GitHub), an application using OSPRay for rendering. With Studio you can use its batch mode to render scenes / scripts, either via existing importers (e.g. glTF) or by writing your own importer-plugin. Studio also has a Python interface to script the scene.

If you contact me with an OSPRay Studio issue, I will be happy to help plan out a solution to your needs. Studio does have an SDL, which is a json representation of our internal scene graph format. And, this can be scripted. Additionally, scenes can be scripted in python.

Hello,

Are you still interested in this request? If so, I recommend that we transfer this issue over to OSPRay Studio and create what you need there. I’m happy to help.
