    Hi Nicolai, it seems the numpy (latest version) not fully support. better to downgrade to 1.26.4. thank you for sharing the video. w

    Hello! Thank you for your video! I have a problem, draw_geometries function downloading very long (more than 1,5 hours, and I still have never been able to wait until the end of the download) and I don't even know why.... why can it be? and how I can to fix it?

    hello The Coding Lib, I have a question. Why we need downsampling?

    • @NicolaiAI
      @NicolaiAI  3 ปีที่แล้ว +2

      To have a smaller point cloud to process, reduce computational cost and processing time. Without losing much information

      ​@@NicolaiAI I followed tutorial Global registration and ICP registration (using open3D library) but a got this: "RuntimeError: [Open3D ERROR] TransformationEstimationPointToPlane and TransformationEstimationColoredICP require pre-computed normal vectors for target PointCloud". I think this error relate to normal vectors, and I also used "estimate normal", but this error always show up. Do you have any recommend for me?

    Hello,,thanks for your work,can you please tell me how can we increase/decrease the size of normals while keeping the size of points constant?Because in documentation they mentioned to use the keys + or - to alter the size of normals but it also changes the size of points.
    Look forward to your response.
    Thanks

      in my case I used pdal split and you can use grid.

    Hi thanks for the tutorials! Very Helpful!
    I get this error while trying to visualize point clouds :
    [Open3D WARNING] GLFW Error: WGL: The driver does not appear to support OpenGL
    [Open3D WARNING] Failed to create window
    [Open3D WARNING] [DrawGeometries] Failed creating OpenGL window.
    Anyone has idea how to solve it?
