5 What is the PowerVR Graphics SDK? Assists in rapid application development, debugging, and performance analysis Educational resource for embedded graphics techniques Develop on Windows OS X Linux Develop for ios Android 5 Linux

6 What is the PowerVR Graphics SDK? Accelerate and optimize the whole development cycle Asset Creation Development Debugging and Profiling + PVRTexTool PVRGeoPOD + PVRVFrame PVRShaman PVRShaderEditor + PVRTune PVRTrace PVRScope 6

7 Utilities & Source Code Assets

8 PVRGeoPOD Industry proven 3D scene data format Geometry exporter tool Plug-ins (Blender, Maya and 3ds Max) GUI Command Line Features Optimize geometry Remove unnecessary data Output POD files 8

9 POD File Format PowerVR Object Data file Optimized deployment format for 3D data Bike Baron Features Stores scene data needed for rendering Easy-to-parse format Supports user metadata Public specification Public source code (PVRTools) Minigore 2: Zombies 9

12 PVRTexTool A feature filled texture compressor targeting all major compression formats Texture compressor and converter GUI Command Line Library Plug-ins (Photoshop, Maya and 3ds Max) Features Convert images to textures Pre-process textures for deployment Supports many texture formats (including PVRTC) Outputs PVR, KTX or DDS files 12

13 PVR File Format A texture container intended for texture formats, not just PowerVR! PowerVR texture file Deployment format for texture data Features Supports all standard texture formats Supports many compressed formats Easy-to-read file format Supports user metadata Public specification Public source code (PVRTools) 13

15 PVRTools Common graphics functions simplified Suite of common graphics functionality Source code library Features Resource loading and management Vector, quaternion and matrix math Print text into a 3D scene Extension management Supports all PowerVR platforms 15

16 Utilities & Source Code Development

17 PVRShaman Visually edit POD scene files applying different materials (PFX) Shader development environment Graphical interface Features Integrates PVRShaderEditor Preview POD scenes Edit and preview shaders Supports OpenGL and OpenGL ES 17

18 PFX File Format Represent an entire GLSL material effect in one file PowerVR Effects file High-level shader effect file Features Easy-to-parse format Keeps related shaders in one file Stores all data needed for an effect Public specification Public source code (PVRTools) 18
