Today
- my apologies for not having a quiz before today’s meeting
- more about critical fusion frequency – the frequency at which a flickering light appears steady to the average human observer
- 60 fps
- Video 30fps or 60 fields per second (even and odd lines)
- Film 24fps but can appear as 48fps or 72fps with double or triple-bladed shutter to show each frame 2 or 3 times
- higher than 12fps perceived as motion
- Assignment 1
- Do you need to use the colours that I have used? You can choose your own colours — think about what information can be conveyed with your colour choices.
- is it ok all the subdivided triangles to be different random colours? Look at how the recursive calls to subdivide the triangle are made and see if something can be done differently there
- The perturbation of the midpoints only applies to the recursive subdivision method
- Window events resize
- Gesture and touch MSDN
- Picking (selecting an object onscreen) is difficult for several reasons - can draw simpler version offscreen and test for colours – that comes up in a later chapter
