patch to allow more than 64 xparts in pano mode
Closed, ArchivedPublicPATCH


If you use pano mode, the system renders your scene by "turning" the camera so it collects XPARTS consecutive images edge to edge. For example, 640x480 with XPARTS=3 will give a 1920x480 image which changes perspective from left, center and right view directions.

If you make a sufficiently narrow render resolution such as 4x480, you can emulate a "slit-scan" panoramic camera, giving a seamless cylindrical projection.

But there was an artificial limit of 64 XPARTS and also XPARTS*YPARTS<64. I found no reason for this limit in the current codebase, so this patch removes it. This lets you render full 360-degree (and wider) cylindrical panoramas with up to 1000 xparts.

(A sample test render is at for your enjoyment. May disappear in a week or so.)

I also allow yparts to go up to 1000, but there's still a check that panoramas are only single row horizontal. I'll check if that's required later. Removing that constraint could allow 360x180 degree spherical projection output.
