DS Texture Memory

mickyg

With regards to the 512kb per screen limit on the DS, how exactly can you work out how many textures fit under this cap? Is there some sort of standard that can be used that gives a rough estimate of texture memory based on texture sheet size, number of sheets etc?

Or is it just a case of saving each image and analysing the memory used? If so, is there an easy way to check this info, such as in Photoshop?

Thanks everyone

I'm not exactly sure how this works, or the reasons behind the limit of exactly 512, but you could always take all your textures that would be on screen at any given time and simply see if they all fit on a t512x512 space in PS.
Example: 4 x 256 texture sheets = 1 x 512

Well you have those 512kb of actual graphics memory, where you can store textures, meshdata and some other things needed to be stored.

the memory a 256x256 texture will take depends on how you choose to store it, there are a varied ways to do that and the best way I believe is a paletted texture for the best usage.

Brad - That's the mistake I first made, assuming that 512kb of memory = 512x512 texture space, but now I realise that's not the case. Thanks for the help though.

Eld - thanks for the link, it seems I'll have to do a bit of research into these concepts.
