Export to High Resolution Image Sequence

Asked by Troy McClellan

Is it possible to export high resolution image sequences. I would like to create dome masters in fisheye format at at least 3K x 3K pixels. The only way I see to do that now is to take screenshots, but the resolution will not work for high-resolution projection formats. Any thoughts?

Thanks,

Troy

There's a very convoluted method to do this, although I'm not sure what the upper limit of resolution is. It is very slow. It's crazy, but it might just work.

1. Use Linux / BSD / Something with X-Windows.
2. Use a nexted X-server like Xephyr
3. Write a script to set the time, take a screenshot, set the time to the next frame time

Potential problems:
part 2: I'm not sure what the resolution limit of the nested X servers is. Also, these nested X servers do not have accelerated OpenGL. You'll be rendering entirely on the CPU, and at this resolution it's going to take ages per frame (possibly minutes).
part 3: You can't set the time to a fraction of a second, so if you want 25 FPS, you're going to be running at 25 seconds per second apparent simulation time.

Can you help with this problem?
