How to display point cloud in perspective mode in Microstation as it is in Pointools?

Hi All,

This issue made me crazy, you can see the point cloud displayed in the pictures below.

In Pic 1 there is the entire view of the point cloud data set which displayed in Microstation, I want to go inside of the buildings to see more details as in Pic 2 which displayed in Pointools, but when I tried to zoom in to find the details, the result in Microstation is displayed as the scene in Pic 3.

Wish someone here can help me out. I tried the perspective mode in MS, but not well.

  • Hi Koalar,

    Ok if I understand well you would like to display point cloud in MicroStation similar to how it is displayed in PointTools. I have created a short video on how to modify the display in MicroStation so that it looks similar to PointTools. Personally I think both MicroStation and PointTools display (which is shown at the end of the video) looks pretty much the same.

    Let's me know if there are still too much discrepancies.

    HTH,

  • Hi Mathieu,

    Thanks for your reply.

    I already have tired your method to view point cloud in Microstation.

    If you fly through a window into the building you will see the difference between 2 software.

    Pointools can help users to fly into the point cloud data with perspective mode, but Microstation, even with view perspective tool, I can't fly into the building. You can try with the same data in your video, just zoom in and through the wall.

    You compared the views in different software with a data set of which there is no cover on top of the building, if there is a roof, you will see the difference.

  • Hi Jan,

    Thanks for converting the video files.

    So now you know what I talked about? They are different.

    Yes, now it is ... finally ... clear ;-)

    The source of the discussed problem is they are not the same tools in Pointools and MicroStation and don't work the same way. It's not the bug, but WAD (work as designed) as they are designed for different purposes. What you use as "zoom" in Pointools is not the zoom in fact, but more "walk through" tool, because camera position is changed. If you use zoom (both in real life and CAD programs), the camera position is not changed, but only camera viewing angle. So higher zoom doesn't allow to walk in behind the wall, you have to change your (camera) position.

    I am not sure if MicroStation offers exactly the same tool, but there are several similar tools available:

    • Walk (key-in NAVIGATE CUSTOM WALK)
    • Fly (key-in NAVIGATE CUSTOM FLY)
    • Navigate View (key-in NAVIGATE VIEW) ...
    • Navigate Camera (key-in CAMERA NAVIGATE)

    What will probably always be different how point clouds are displayed during a view dynamics, because MicroStation simplify objects when a view is changed to speed up the process. But maybe somebody else know a workaround.

  • Hi Jan,

    I really appreciate your helpful answers. I will follow your instruction to try the view method in Microstation :)

    As laser scanning technology more wildly used then before, point cloud will also be used very often in design and reverse design work.

    In my opinion, the perspective view mode like pointools has will help either point cloud data or models to display well while working with both of the dataset.

  • Hi guys, just read through all your posts with interest. This is something I struggled with when starting with MicroStation a few years ago.

    My tip: Go to Pan mode, check on the 'move camera' option, then right click to come out of Pan mode.

    Then when you use the scroll wheel to zoom it maintains your perspective 'amount', without this switched on when you use the scroll wheel it changes the perspective (scroll up goes towards orthographic projection, scroll down increases perspective amount), instead of moving the camera.


    This is a test
