change camera position

[pascalisfort]

Hi, I begining to use PPTK for point coud viewer.

But I need help: when I opening a new point cloud. I use this code to open xyz point cloud
v = pptk.viewer(xyz)

Every thing works fine, but when I try to change the camera position
v.set(lookat=(1.8, 8.3, 6.67) )

The camera is moving,but when I begining to use mouse to navigate, the camera position come back to the original position (same as when I open the point cloud)

Do you have an idea how to set camera position and staying there

Thank you
Pascal

Same if we use the (undocumented ;) ) load function

My intent was to use pptk to show kinect collected data, so lots of refreshes
And eventually make icp registrations :-)

Stuff that could help:

• make the viewpoint persistent
• create the viewer empty, silently set the view pos, then load the points
• unloading / reloading the points (by index is fine)
• unload & reload the points then refresh afterwards (avoid the ugly blink effect)
• after a few hundred of load operations, pptk crashes / wont load points anymore. I guess there's memalloc issues?

Anyway, would be really nice if you fix it

Meanwwhile, i'm back to my axonometric view that i dirty coded with opencv :D

btw, from the docs the get roll yaw pitch is float 64 and the set if float 32
not really a problem, but makes it awkward
