Metashape XML parsing was broken when it contained camera groups. I changed the way it iterates over XML elements to iterate over elements of a given type (camera) rather than...

fix "ns-render interpolate", so that it can render the input views, add crop box

2

Previously, `ns-render interpolate`: - Ignored distortion parameters - Used an interpolated focal length, but principal point was from the first camera - Rendered all images with the same size, even...

When does camera optimizer make things worse? Can it be detected?

3

Posting this to trigger a discussion: I've seen cases where the camera optimizer (with default parameters) makes things worse. It is known to degrade results on synthetic datasets (eg blender...

Why opacity compensation on the 3D filter? This makes small Gaussians non-opaque.

7

The justification for the 3D filter in the paper comes from the fact that "a primitive smaller than 2Tˆ may result in aliasing artifacts during the splatting process, since its...

**Describe the bug** The Metashape import functionality in nerfstudio incorrectly maps tangential distortion parameters `p1` and `p2`, leading to incorrect camera distortion when importing Metashape projects. ## Root Cause Metashape...

nerfacto: Weird circular crops and ripples (when using no scene contraction and no render crop)

11

**Describe the bug** When using no scene contraction, I get weird empty discs (no rgb, no accumulation, no depth) in renders, unless I enable "crop viewport" or enable scene contraction....

In the current version of the code, each flash generates two events: - one for the rising edge (positive=True) - one for the falling edge (positive=False) However, the event matching...

Hi, First, let me thank you for this code and the paper. I think this is a great problem and I like your solution. However, I found that there are...
