video using fresnel

[jude vishnu]

Dear all,

Is it possible to have a video of trajectory created by Fresnel?

Is there a documentation for this?

Regards,

Jude

Hi Jude,

Yes, this is possible. I have done it before but I no longer have the scripts available. You'll want to search for something like "PIL images to video". Render each frame of the video with fresnel, then use PIL (as shown in the tutorial on saving output) to write an animated file.

Here are some pages with examples using various libraries (PIL, cv2, imageio):

Best,

Those all look like good options. Here is one more option to consider: moviepy (https://pypi.org/project/moviepy/)
