update tstamp (frame index) when removing keyframe

I found the frame indexes in the final `tstamp` do not correspond to the correct images. So, it needs to update the frame index so that downstream applications can correctly...

How to build project linking to Open3D with CUDA support

### Checklist - [X] I have searched for [similar issues](https://github.com/isl-org/Open3D/issues). - [X] For Python issues, I have tested with the [latest development wheel](http://www.open3d.org/docs/latest/getting_started.html#development-version-pip). - [X] I have checked the [release...

question

Open3D makes "glEnable()" having segmentation fault

question

Any tutorials or examples on the usage of GUI API?

question

texture contains pixels that exceed the [0, 1] range after senor moved and scene_params.update()

## Summary I made a simple scene and wrote a script to render multi-view images. But after the position of the sensor was modified and the scene parameters `update` in...

Angle of polarization of surfaces behave unexpectedly like textures when rotating camera

## Summary When rotating the `sensor`, AoLP map also rotates as if the AoLPs were the texture of the object. But in reality, the AoLPs will change when the poses...

OOM with only ~12MB memory allocated / requested on GPU

Hi, I tried to run ref-nerf but no matter how small the batch size is, the OOM problem would arise. I am not sure if it is the bug of...

[Discussion] Make `eps` in the finite difference exponentially decreasing

I just notice that the finite difference in `geometry.py` is similar to the numerical gradient computation of Neuralangelo (CVPR 2023). Maybe the exponentially decreasing `eps` strategy in Neuralangelo can be...

"--num-rays-per-batch" does not work for "ns-export poisson --texture-method nerf"

**Describe the bug** I found "--num-rays-per-batch" does not work for "ns-export poisson --texture-method nerf" when I tried to export mesh and constantly got CUDA out of memory. **To Reproduce** Steps...

Any guidance in training an good sdf model with background model?

I tried neus-facto/neus-facto-angelo/neus-acc/neus and found that exported mesh would be very terrible with a background model in these methods. But without the bg model, the mesh would be much better...
