[QUESTION] Export to Mp4? #340

Open rrzhang139 opened 1 day ago

Are there options to export to mp4 and defining camera parameters like Blender? What is an alternative to this? Thanks!

Hi @rrzhang139, if you look at our examples, most of them export the result as a USD scene using warp.render.UsdRenderer. From there, you should be able to import it in Blender or any other 3D software and render it however you like.

An alternative could be to use warp.render.OpenGLRenderer instead and using its get_pixels() method to store each frame as an image. Then you could use ffmpeg to convert these as mp4, or maybe even use Matplotlib's FuncAnimation class.
