realtime visualization of live objects/point clouds!
« on: October 25, 2013, 03:35:16 am »
Hi there,
Recently I've been thinking of connecting kinect to mobile device!
Is there any ways for realtime visualization of live objects/point clouds using jPCT AE?
So assume that I have already a program that grabs point clouds from kinect, and then I want to show them in jPCT realtime! I could zoom in, move the live object!
Can it be implemented with jpct AE, with good responsiveness and without high computation? I want to go for JAVA!

I'm not sure...sounds like some custom renderer might be the better choice. How exactly will such a point cloud be rendered? As individual points or will it be converted to a polygon mesh somehow?

Well, there are both options; but I think individual points will be easier to render.
You can watch this: http://vimeo.com/41377003
If we convert the point clouds to objects, and then stream them frame by frame, I think it is not feasible, both from the computation part and the bandwidth...What do you think?
If we could do something like this in jPCT AE, it could be really nice :-/

Well, jPCT-AE is polygon based. It can render points but only in one color per object and still with polygons as basic primitive. I think that a custom renderer might be the better solution for this task.
