Hello everyone.

I'm trying to do a text labeling (rendered in screen) to some specific points in a 3d space moved with peasycam. How can I get the screen coordinates of a 3d point?

Thanks!

Hi everyone. What is the best way to render 2d text (in the screen) while having things happening in 3d?

I've tried with textmode(SCRREN) and it works fine with only the text but I don't achieve for example drawing 3d lines at the same time that the text is rendered on screen (draw the lines but in the xy plane).

In addition I've read in the wiki that textMode it's going to dissapear in processing 2.0, so what is the best way from now on?

Thanks!

Hi, I've been working in a 3d application with processing (using opengl and picking library), it's not complete yet but it works on processing so far. The thing is that I've tried to export the applet and it shows this java error running it with the browser:

java.lang.SecurityException: Permission denied: http://download.java.net/media/applet-launcher/applet-launcher.jar

at sun.plugin.util.GrayBoxPainter.setProgressFilter(GrayBoxPainter.java:220)

at sun.plugin2.applet.Plugin2Manager.setupGrayBoxPainter(Plugin2Manager.java:2290)

at sun.plugin2.applet.Plugin2Manager.access$700(Plugin2Manager.java:102)

at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Plugin2Manager.java:1493)

at java.lang.Thread.run(Thread.java:680)

Excepción: java.lang.SecurityException: Permission denied: http://download.java.net/media/applet-launcher/applet-launcher.jar

The objective for this is to run directly online as a main page for a web. Is there any problem with opengl or the use of libraries for this?

I'm programming it in Mac OS by the way.

thanks!
