what is best for a simple 3D animation

Hi everybody, I'll start a program that I will eventually port to the iPod touch platform, but I also want to have a mac counterpart. It will involve a simple animation, a sphere that the user can spin faster with his finger (in the iPod Touch of course), later I'll make it a little more compl

Hello everybody, I have a question relating NSImage and NSBitmapImageRep. I have a stream of data that I want to display in a view and it's not in any standard image format. So I created an NSBitmapImageRep, then I filled the bitmapdata with the data and drew it in the view with drawInRect: met

NSImageRep simple code

Hello everyone, I'm trying to understand how NSImageRep works, so I read the docs and came up with this simple code that seems to... do something. I'm confused about what's actually doing, I only see a big black block in my custom view. My intention is to make a 2x2 pixels image with differe
