Hey,
I was looking for information on the texture units supported on iPhone 3G and 3Gs. First, what are the texture units? Is this referring to materials that have two textures such as the lightmap materials? What is texture combining?
Thanks!
pre 3GS has 2 texture units, 3GS+ has 8
the number of texture units basically tell you with how many textures you can work within a single rendering pass.
When you say per rendering pass, are you referring to number of textures used per shader i.e. shaders that take multiple images? Can you please further explain render pass?
Thanks!
I’m sorry but thats kind of an advanced topic.
I would recommend that you readup on the shaderlab documentations and the documentations on the existing shaders etc to get a feel.
No problem. Thanks for pointing me in the right direction! I’ll check out the shaderlab docs : )
