Splitting up images for the sake of saving RAM

Wondering what your opinion is on this before I test the theory....

I'm about to split a 1024x220 image into 2x 512x110 images to see if that would save on RAM? Or would that be redundant....hmmmm.....(sips wine)

    how can you split that? the 1024 is 4 times bigger then the 512 one

    and also the ram count on 2,4,8,16,32 (the power of 2)

    What do u mean HOW? 1024x220 /2 = 512x110.........

    it is 2D not 1D

    you have to split to 4 images

    Huh? It's a simple question regarding RAM man...Just wondering if more RAM is saved if I split a single image in two equally.... C'mon one of the regulars please lol.

    Hi TTG, as recommended, cut your image into 4, because:

    Your 1024 x 220 is loaded into RAM as a 1024 x 1024 image. So if you cut it into 4 equal pieces, each measuring 256 x 220 each, these will be seen as 4 images each with sizes of 256 x 256. This would make an area of 512 x 512, which is a quarter the memory needed than if it was seen as 1024 x 1024.

    TTG what are you talking about? You say you will split in to two then it should be 2 512 by 220 or 2 1024 by 110

    Don't know who is the irregulars lol

    @TTG I don't want to start a fight here, but you are the one that start to attack people

    No one implied I was starting a fight...it would help if you wrote proper English though.

    I just wanted to briefly reopen this and say that if it was me, I would not split up the images.

    Your images get loaded into texture memory. The memory is allocated in "chunks" that have sizes that are powers of two: 2,4,8,16,32,64,128,256,512,1024.

    However, the memory "chunks" do NOT have to be square.

    Your image would fit into a memory chunk of 1024x256.

    Splitting up the image wouldn't save any RAM in this case.

    In fact, it would add another Actor to the Scene with all the performance overhead that that would cause.

    So I vote NO to splitting up the images ;)

    Thanks from me, Joe, useful to know. I always thought that it was seen as square of the max. dimension (on this week's episode of Square and the Max Dimension....) Don't know how that got into my head. Anyhow, i learn something new every day! :-)
