Hey!

I'm writing image-mosaic script that's using 4000 tiles to create a final 50,000 x 50,000 pixel image.

My approach was to sort the images and draw them to an FBO, but I get an error any time I try to allocate an FBO at 8,000 x 8,000: (ofFbo: FRAMEBUFFER_UNSUPPORTED)

What I've been trying is:

  • Create an FBO object
  • Draw the ofImage files to the FBO
  • Read the FBO to an ofPixels object
  • ofSaveImage the ofPixels to a png file

Does anyone have any suggestions for a better way to do this, or a way to fix my issue (is it just I should swap from my underpowered Macbook to my workhorse PC for more graphics memory)?

I've never worked with this high resolution before and am totally at a loss.

Thanks guys!
