10. iOS and OpenGL
OpenGL ES 1.1 supported everywhere
OpenGL ES 2.0 supported starting with iPhone 3GS (2009)
EAGLView and Xcode template
Demo
Performance Tools
Apple sample (there is a template!)
11. 3D Modeling
Modeling and Animation
Plethora of formats (Wavefront OBJ, POD, Collada, Maya)
Applications:
Commercial, or
blender
Thriving marketplaces for models
12. blender
Front View Numpad-1
Back View Control-Numpad-1
Left Side View Numpad-3
Right Side View Control-Numpad-3
Top View Numpad-7
Bottom View Control-Numpad-7
Rotate Model Numpad-2, 4, 6, 8
Move Model Control-Numpad-2, 4, 6, 8
Zoom Model Numpad-Plus and Numpad-Minus

!! User preference to “Emulate 3-button mouse”
RMB = Two-finger click on track pad
Fine control is difficult with mouse or trackpad
Multi-touch Trackpad
Rotate Model Two finger rotate
Move Model Two finger drag
Zoom Model Two finger pinch

1. OpenGL: hardware optimized display layer\n2. Desktop vs. Mobile\n3. Different generations\n4. Fixed function simpler\n5. Programmable more powerful\n6. Security Questions: Graphics a the new viruses.\n\n
OpenGL on desktop platforms\n
OpenGL ES on mobile platforms\n\nSubset of OpenGL\n\nPhone7 supports Direct3D\n
Surfaces are defined by vertices\nSurface normals define which way a surface is facing\nSpecialized structure allow re-use of vertices to minimize data size\nTextures are samples of material which are applied to surfaces\n\nMain operations: Translation, Rotation, Scaling.\nLighting: sources, position, intensity, color, type\n\n
