Developer Considerations

• Biggest issues are not 3D graphics
• Scalability in production
• Hardware specific extensions
• Always provide standards based default behavior
• Lighting through textures
• Power considerations
• Target device release schedule

3D Hardware Development Kits - HW

• Types of 3D configurations
• Baseband processor
• Applications processor
• Integrated 3D IP with processor
• Discrete graphics chip
• SOC (system on chip) game engine
• Hardware devkits form factors
• Apps processor development motherboard
• PC PCI interface card with display
• Form factor prototype
• Easy to get hardware, hard to get target
  environment

3D Hardware Development Kits - SW

• SDKs
• Windows 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
