19 3D Native direct low-level access to the Hardware is not realistic! Developers prefer to write to a single API support by all HW available Standard maximises available content, high quality content helps drive sales Khronos APIs OpenGL ES 1.1/2.0, OpenVG, OpenMax, EGL, etc. Conformance Test to assure proper implementation on Devices

22 OpenGL ES 1.1 VS

23 : OpenGL ES 1.1 OpenGL ES 2.0 Software Vertex Processing struggles to handle ~150K Polygons/Second with 100% CPU Load while dedicated specialised hardware easily handles more than 2.3M Polygons/Second with minimal CPU load Hardware Pixel Processing using various hacks and without filtering struggles to draw 5 MPixels/Second with 100% CPU Load while dedicated specialised hardware easily handles more than 50MPixels/Second with minimal CPU load 23

24 OpenGL ES 1.1 Batch API Calls CPU Consider Texture Pages, Software Transform, Etc. Use Optimisations tools and guidelines provided in SDKs culling LOD Do not submit the whole world geometry! Consider LOD variants of complex objects OpenGL ES Has to implement according to specifications, no short-cuts possible Use the smallest number of lights and lowest complexity lights Consider using Per Pixel Lighting (DOT3) instead MIPMapped Use HW specific compression formats such as PVRTC Use Bilinear Filtering with Nearest MIPMapping Don t use a 1024x1024 texture for an object 10 pixels on the screen Alpha Blending Alpha Testing 24 More recommendations available from and

25 OpenGL ES 2.0 OpenGL ES 1.1, : Shader Precision Use lowp and mediump where possible Avoid using highp or mediump for all operations branching Über Shaders which allow increased batch sizes Shader Texture Maps E.g. Normalise through a cube map rather than using maths Shader Using 1000s of instructions for every pixel on the screen is not fast 25 More recommendations available from and
