Hi

Someone knows if there is something like this http://www.jhlabs.com/ip/filters/index.html to use in processing.

it would be nice to have a library with those effects but i can not find somethig similar


thaaaaaaaanks

im trying to use an externall dll provided with an app to make calls from another app.

i followed the hack paga about jna but im receiving the error:

cannot find a class or type named "org.xvolks.jnative.util.PSRemoteLib"  where PSRemoteLib is the name of the dll and the name of mi class

Hi

Im developing a photoboot with chromakey i have the chroma part working good with loaded images but now i want to implement an external camera. I want to get good quality photos so i think that i have to use a dslr camera but i dont find any library or sdk that let me do that.

Its there any way processing can comunicate with a dslr camera to get photos instead using a webcam ??


thanks

Hi

I have a point cloud stored as a ArrayList of vectors (Vec2D). I want to make a triangulation, but the points are too near.

How can i get all the points that have a separation of N pixels beetween them, so i get a simplified version of the first arraylist to do a triangulation

Hi

Im rendering a pointcloud coming from simpleopenni library. I create an arraylist of points using toxi Vec3D

And to render the arraylist, i create a GLModel
points = new GLModel(this, maxPuntos, POINTS, GLModel.STREAM);

I want to know how can i improve my render settings to get a better output (now seeems like pixelated and make a extrange effect like "moire").

But when i render the model, it looks like hard edges arround points.












For example i tried to set an smooth to render the points, but i dont see any difference
gl.glEnable(GL.GL_POINT_SMOOTH);

My goal is to get something like the house of cards pointcloud or at least i want to recognize myself in the pointcloud.

I know that this is generic cuestion, but i have spend a week trying to understand how can i improve that....but i dont find a way. Where can i find docs about that??? And i would be very happy if someone says me what im doing wrong.

Puntos is a class where i track the pointcloud

Hi to all

I want to know if there is somethig similar to pcl( pointclouds.org) in processing.

I want to draw a point cloud from kinect and play with the points, like those music videos that begin to appear in youtube ( http://www.youtube.com/watch?v=DxSMefslOf0, http://www.youtube.com/watch?v=8nTFjVm9sTQ,...). i saw superpoint library but im not sure if its  the best way to go.

Also, wich is the best way of render a point cloud, i used point() but my framerate dropped so much.

declare an arraylist
ArrayList<Vec3D> puntos3D = new ArrayList<Vec3D>();

i add the points
puntos3D.add(new Vec3D(v.x, v.y,v.z);

and draw
translate(v.x*factor, v.y*factor, factorZ-v.z*factorZ*0.93);
point(0, 0);


Thanks for yout time

Hi

Im developing an tracking app based on kinect, the program does those things rigth:

      - obtain a blob with opencv
      - delaunay that blob using poly2tri



But now i want to put those triangles inside a pbox2d body and i always get assertionerror creating the shape.

How can i draw a complex body created from triangles in pbox2 ?????

I dont know if the delaunay that i get using poly2tri is usable directly in box2d (vertex order, minimun size,...)

In openframeworks there are methods to do this easy but i can not seems to be capable of doing in processing.


Please, give me some light on that !!!!!!!!!!!!!!!!!
