LGM Weird results when testing on customized images

Thanks for the amazing work! I tried to run the gaussian reconstruction part on 4 images I rendered, the four images have elevation and azimuth of: (30, 30), (-20, 90), (30, 150), (-20, 210) and I have set it in the prepare_default_rays function. 001 002 003 004

However, the results rendered from gaussian looks quite weird: https://github.com/3DTopia/LGM/assets/23579918/e82ce6ac-300e-46c3-8772-54bf5ef9b411

Is there anything else I need to change?

@cwchenwang The elevation I used is negated, i.e., +30 is a looking-up elevation, while -30 is looking-down. You can try again with negative elevations.

@ashawkey Thank you! It looks much better now, but seems not that good, is this expected? https://github.com/3DTopia/LGM/assets/23579918/29a8f98d-4981-4cf7-9f04-e2a69fc6b942

It still looks a little strange... maybe you can also adjust the camera radius and fov, if you are using different values? Also, it seems the 4 views only cover the front 180 degree, which may also lead to worse quality.
