OpenGL flicker problem
Aug 29th, 2007, 2:07pm  
Hey,

I am trying to create a generative program something like tendrils and i want to use the OpenGL library but i've got a weak graphics card and when i put the background call in the setup function i get a flicker effect and when i put it in the draw function it overwrites the past segments(lose, lose). Is there a work around?

Thanks,
Tarig

use arrays or the ArrayList or Vector class to keep track of the current objects that are alive.

then run background and the code for drawing all objects in the draw() function..

each object should be a class, with variables for positioning, moving, size, or whatever you need.. you'll also need a drawing function, and some code to make it move around

good luck
