I am using zed2i with segment anything model which is working fine . now i want to do 3d reconstruction of of object using image captured, after doing all the steps involved in downloading all the dependencies i am not able to import ogl_viewer.viewer as gl.
pip install PyOpenGl PyOpenGl_accelerate

Hi,

If you took the example of our samples, there is a ogl_viewer folder alongside them. You need this folder alongside your program so that it can import it right.

Hey @alassagne thank you for the quick response. I did what you had instructed me but i am facing a new issue with open gl

Hi,

It’s because you took an opengl viewer that was in some other code but does not work with yours. You need to adapt it a bit.

its from the same code given by zed samples

What does happen when you run the original sample ?
If you have an issue, it can also be a mismatch between your SDK version and sample version. You can ensure you have the right one by using the sample that are provided in the SDK installation folder.

The program simply does not run and mapping
