The second example is adopted from the Million Particles example from the MSAOpenCL library. I developed it with Processing 2.0 alpha version without using the library and the Pointer class. All the memory buffers are standard Java.nio.Buffer. The performance is … Continue reading
I ported the particles demo program in JavaCL to Processing 2.0 alpha. It has reasonable performance in my iMac up to 500,000 particles at twenty something frames per second. The video is captured using the QuickTime screen recording. The performance … Continue reading
The existing OpenGL codes for Processing do not work in the 2.0 alpha. Here is an example code segment I modify to use the new PGL class. import processing.opengl.*; import javax.media.opengl.*; GL2 gl; float t, s, c; void … Continue reading
I have done a number of testings with various Java implementations of OpenCL and Processing. The major Java bindings of OpenCL include JOCL Java OpenCL JavaCL The are two major OpenCL libraries for Processing at the time I do the … Continue reading
This is the second test of the Neurosky MindWave brain sensor in Processing. I use the fluid simulation library diewald_fluid with the GLGraphics rendering library, to display the alpha, beta, gamma and theta wave components.
I try to work out another version of the DirectShow for Processing classes in the last post. In this version, I write the movie data directly to an OpenGL texture object. Below is the modified version of the DMovie class. … Continue reading
I adopt the DirectShow Java Wrapper to work in Processing with two classes, one for movie playback and one for video capture. At this moment, there are just two Java classes, not an individual library yet. Since it is for … Continue reading
I try out different video playback mechanism in the Processing to compare their performance. The digital video is the one I used in the last post. It is the trailer of the film Hugo. The details are: 1280 x 692 … Continue reading
I have done a simple performance comparison with a number of video playback methods in OSX. It gives me some ideas about which development platforms, namely the OpenFrameworks and Library Cinder to work on with high quality video playback. The … Continue reading
People switching from Processing to OpenFrameworks or other more serious development platforms due to performance consideration. I have done a few searches and found that there are a number of libraries using different Java bindings of OpenCL, Vertex Buffer Object, … Continue reading
