This page's goal is to describe parts of Nintendo's OpenGL implementation for the 3DS as we reverse engineer it to better understand how to use the PICA200.

Some of the information on this page is specific to Steeldiver : Sub Wars. The reason for this is that it's a fairly graphics-heavy game that's available on the eShop for '''free''', so it seems like a good target for a community REing effort.

== Description ==


The PICA200 is an opengl ES 1.1 compliant GPU manufactured by DMP. It comes loaded with a number of extensions that make it similar to an openGL ES 2.0 compliant GPU (ability to run programmable vertex/geometry shaders, for instance). Because of this, Nintendo wrapped GPU access into an openGL ES 2.0 implementation with some limitations. As the fragment stage of the pipeline is non-programmable, Nintendo instead gives developers the ability to configure a number of fragment-related values through glGetUniformLocation and glUniformXX. See below for the full list.
