setup — load more images

ludimation commented 9 years ago

Would be great to load more images:

there are close to 700 in the images directory now
can only load approximately the first 64 images before the build throws errors in xCode

Stealing this one to see if I can get it running.

Build pauses pretty consistently on image 64 and image 128, then throws an error:

Changed max files to load to 127 which still runs. Gonna give this one a rest for tonight and show it to someone else who might be able to figure out the stack overflow.

Can't recreate error, I have successfully loaded as many as 200 images. Using OF 8.3; OSX 10.9.5. It does pause when loading at 64 images and 128 images, so I suspect that the vector is resizing once it's full. It might make sense to resize/init the vector to the size needed before loading the images from disk. This way the vector resizing allocation doesn't have to happen during image load.

ludimation commented 9 years ago

We re-sized the vector (so it doesn't pause at 2^n images), but it's still crapping out at around 265 images which is likely because we are running out of VRAM (currently have 1GB on my laptop).

DONE

re-sized the vector (so it doesn't pause at 2^n images)
re-sized all images to be 540 px on short side (1/4 filesize from previous dimensions)
changed compression to OF_COMPRESS_ARB

ludimation commented 9 years ago

This is pretty much done for now. Still having trouble building it for OSX 10.7, but I'm moving that to #28. I also moved over RAM / VRAM issues to #27.

setup — load more images #11
