This presentation made at TI Developer Conference 2008, introduces the options available for developers to create User Interfaces on TI SGX based platforms.

1. Building advanced user interfaces using SGX Graphics core on OMAP3 Prabindh Sundareson ( [email_address] ) DSPS Texas Instruments

3. Video vs Graphics It’s a state machine - Setup the stage, lighting, actors… Then draw it ! Based on motion between frames OpenGL based Graphics Video

4. The OpenGL ES 2.0 Picture OPENGL Full version ES version Common Common-Lite GLSL companion GLSL-ES companion What we miss in ES compared to desktop version: Polygons, Display lists, Accumulation buffers,… Currently in 3.0 Currently in 2.0 Currently in 1.0.16 Currently in 1.20 EGL Currently in 1.3 Core GL Spec Vertex/Frag shaders Platform interface and Configuration setup EGL Currently in 1.3

6. Primitives, Vertices … D B C A *Note the orientation

7. The pipeline… Vertex shader outputs position of vertex, calculates orientation Fragment shader outputs colour

8. Sample OpenGL ES 2.0 program Handle = get_platform_specific_window_handle(); eglGetDisplay (handle); eglInitialize (); eglBindAPI ( EGL_OPENGL_ES_API ); eglChooseConfig (); eglCreateWindowSurface (); eglCreateContext (); eglMakeCurrent (); //Compile and Load the shaders before this step … float afVertices [] = {G,H,F, F,H,E, E,A,F, F,A,B, …}; glEnableVertexAttribArray (0); glVertexAttribPointer ( VERTEX_ARRAY, 3, GL_FLOAT, GL_FALSE, 0, (const void*)afVertices); glDrawArrays(GL_TRIANGLE_STRIP, 0, 4) ; eglSwapBuffers(eglDisplay, eglSurface); Setup Actors Show Keep showing the actors, in a loop, change view/position/texture ..

17. Texturing with SGX - Example An example Window manager using texturing and SGX only
