[LumenRT] How do we recall a Microstation saved view ?

Hello Christophe,

When we export file from MS with Saved views then saved views will be displayed under Movie Editor > Imported Clips

Thanks & Rg

Thanks & Rg

thanks , I see it now after MSCE exporting

I'm not at my desk to try this out, but it would help if someone has some insight into this before I start.

If I setup a camera with Photomatch in CE15 (ie. an accurate 3 point camera projection), and do a Save View - how accurate will the resultant Imported Clip view be in LumenRT? I need it to be 100% accurate to merge the resultant LumenRT render with my original site photo.

Related to this - what would be the best way to set up a LumenRT animation path to accurately coincide with helicopter/ drone footage?

Thanks,

Max

Hi Max,

My experience has been that the camera is positioned correctly, but the focal length is wrong.

The camera in LumenRT appears to have a crop factor of about 1.32x

Once you've done your Photomatch, find the focal length of the lens in MicroStation by opening the Camera Lens dialog (key-in DIALOG CAMERA). This will display the Focal Length of a specified view.

Once you know MicroStations camera focal length you can multiply it by the LumenRT crop factor (1.32x) to determine the equivalent LumenRT focal length.

To accurately adjust the focal length in LumenRT I do the following:

1. Click on the desired keyframe and then make a new clip base on that keyframe.
2. In the timeline toggle the keyframes to Splines. 
3. Activate only the Camera Focal spline (the green spline)
4. Select the control points.
5. Right click on a control point and select Numerical input...
6. Enter the LumenRT focal length (the MicroStation focal length multiplied by the 1.32x) into the Value: field. Click Ok to see the results. 

This method allows much finer adjustment of the focal length than the slider in the LumenRT camera settings.

If you follow this method you should be able to get the LumenRT camera to match your MicroStation Photomatch camera, and thus your original photo.

Ron

Brilliant - thanks Ron. I appreciate the time you took to put this together.

Hello,

I posted a question in the visualization forum about LumenRT roadway section and have not got any replies and was wondering if you would be able to help me.

Thanks
