OpenCL Combined: Optical Flow, Fluid Simulation & Particle System

I wanted to have a similar flow functionality as Memo's ofxMSAFluid: http://memo.tv/ofxmsafluid.

Looking around a found almost all the functionality on or via kineme.net:

So it made sense to return the result.

Here it is! With a little run through in the attached video.

Note: I created this video using a geforce 480 (with 480 cores). The optical flow and fluid simulation have a resolution of 512x512 and there are 1.280.000 particles. (some visible, some not)

I'd appreciate feedback on optimal settings for your systems. (the attached patch has a resolution of 128 with 128.000 particles)

cheers!

osceleton + rbg or depth

fiebigc's picture

hey, is it possible to put the rbg or depth image of the kinect under the ocsceleton? so it looks like the openNI sample. saw "itsthejayj" stuff but i have no clue how to manage that.

and would it then be possible to manipulate a cylinder a bit like the image attached? i think i saw a osceleton manipulating metaballs?!

kinect augmented reality

dust's picture

so i planned on just drawing something on the screen with my kinect turns out this augmentation was way more interesting than any ir tag method i have tried before.

there is this very specific distance from the kinect where the tracking is just phenomenal. i'm dubbing it the sweet spot.

so the accuracy here is a bit offset as i'm using my i-sight for augmentation.... it is slightly below the kinect so the perspectives are not completely lined up but for this initial unintended experiment it works. going to tighten it up a bit.

actually works better than any ir tag methods i have tried in the past.

Augmented reality with fixed background

LukeNeo's picture

Hi guys, I’m a QC newbie, I come from videogames programming (most of the time using OGRE). I’m currently trying to add some simple 3D objects to a real scene: some sort of augmented reality, but with fixed background. I mean: I have a background image of a 3D environment (the interior of a room for example), and I’d like to add cubes/planes/and so on so as to match the perspective of the photo. Take a look at this first experiment: I used 5x“cubes” and “Kineme 3D Plane Generator”->”Kineme 3D Object Renderer” to create che 3D scene, all inside a "lighting" patch, witch is inside a "Kineme GL Field of View". For the cubes, I reach an “almost realistic” perspective, but the plane hasn’t got the right perspective at all (even if I try to move it inside the scene), and I think that it means I’m not working in the right way. I've tried also to use "Kineme GL Frustum" instead of the field of view, but it seems not to e the right solution. My question is: “what is the right way to recreate a perspective projection so as to match the background perspective?”

Thank you for any kind of help! :)
