loading/displaying lots of images in OPENGL
Feb 20th, 2010, 7:04pm  
okay i'm loading and displaying batches of 320x240 images, and i can load somewhere around 300-400 of them into the sketch before it runs out of memory.

are there any ways to increase this number?

i'm using the Processing image() function for displaying. Are there maybe alternative ways for displaying images as textures which compress the source images somehow and/or increase performance?

thanks!

The memory for OpenGL is unoptimized. It's using RGBA and it requires a lot of memory. You may try two things:

1- Increase your memory allocation: http://processing.org/reference/troubleshooting/#memory

2- Try to load textures only when they are required (Do you really use 400 images at the same time?).
