Lights bug - Memory waste
Jan 3rd, 2008, 5:06pm  
There is a severe memory leak when using lights in OPENGL mode (P0124):
PGraphicsOpenGL.java:
  .directionalLight() and .pointLight() are both calling
  .glLightNoAmbient() which then creates a new FloatBuffer
each time it is invoked, which normally happens for each frame. The code should be changed to generate the FloatBuffer only one time! This bug causes massive invocation of the garbage collector.

if so, please file a bug report in our bugtracker:

... and please don't double post.

thanks!

Yes, I've tested it a couple of weeks ago with the same result and I looked into the latest code which showed that the FloatBuffer is still created within that function for each call - and yes I've posted it to dev.processing.org/bugs yesterday (but I can't find it there anymore - ???!?!?!)
