Developer Considerations

Biggest issues are not 3D graphics

Scalability in production

Hardware specific extensionsAlways provide standards based default behavior

Lighting through textures

Power considerations

Target device release schedule

3D Hardware Development Kits - HW

Types of 3D configurationsBaseband processorApplications processorIntegrated 3D IP with processorDiscrete graphics chipSOC (system on chip); ‘game engine’

Hardware devkits form factorsApps processor development motherboardPC PCI interface card with displayForm factor prototype

Easy to get hardware, hard to get target environment

3D Hardware Development Kits - SW

SDKsWindows desktop wrapper (not emulation)Cross compile libraries for target platforms

Host PC is normally Windows

Talk with target machine via ethernet or SD/MMC

Raw alpha efforts – but improving

3D is one of the easier parts to port between platforms

Audio, input, memory management, file system

Always profile your apps, identifying bottlenecks is key to good performance
