Project 3d point cloud into 2d based on viewer-based perspective

Post by arif_rahman5 »

Hello everyone,

I'm currently working on a project that requires the 3d point cloud to be projected into 2d point cloud, but based on viewer-based perspective so i can compare it with other data captured by thermal camera. I've tried using multiple & scale but it only projects the point cloud orthogonally. Is there any method to project it from viewer-based perspective?

Thank you in advance,
Arif

Well, you can create a 'camera sensor' via the GUI. But then, there's no simple method to project the points in the camera world. You would have to do it programmatically...

Since it is needed to compare over an image. Wouldnt simply switching to orthographic (F3 key) do the job? Then just hit screen capture in keyboard. May be there is screenshot tool in CC, never used such.
May be Rasterize tool could implement the "current view" option rather than allways using top view.
