Question by james 6 · Mar 29, 2011 at 10:24 PM · shaderiphonegraphicsresolution

graphics look bad on iphone 2g

hi, i have written a shader which is suppose to make an object transparent. I ve loaded it onto a 4g phone with 4.1 ios and it looks fine. However when i run it on a iphone 2g with 3.1 ios i cant see the object with that shader attached. How do i fix that

another issue i have is, i have a jpeg file i use it as the texture for a cube which is used as my background. It looks fine on the 4g phone, but looks absolutely garbage on the 2g phone. The resolution of the jpeg i have is 1024 768 pixels. does the pixle has something to do with this??

Post your shader. Never use a jpeg unless it came directly from your camera. Use square textures.

Yes. Use power of two, as well.
