Need help with : Point cloud to Unity + Oculus dk2

micropolius

Hi there.

I need some advice from all the technical artist around here.
I have a photographic point cloud (.pts) file.

''My client asks me if I could turn this file into a VR enabled tour.''

I don't know what to answer. Anyone here have experience with Point cloud data?

There are plugins for Maya, and Max now has native support for point clouds.  You would need turn it into geometry and bake it out as an FBX.  Here's a guide for that in Max.

From there it's as easy as adding it to a Unity scene and turning on "Virtual Reality Support" in the player settings to view it, then you can work on user controls.

I haven't taken a point cloud all the way like this yet, but I've done the individual steps, so as long as the source point cloud data is any good then it is indeed possible.

No problem.

This depends heavily on the size of the point cloud. Best would be a point cloud asset for unity

Because you want colored dot-like billboards for each point or the VR tour will look a bit strange.

It's possible to use 3D-Models for each point but above a few 100k points this gets really really slow (each point would be made out of at least 4 tries. So 100k point-cloud-points will transfer to (at least) 400k polygon model tries/points
