Goals:
  1. Use MicroDEM to download and edit Digital Elevation Maps
  2. Build fight paths
  3. Import models and animate
Key Points:
  1. Using MicroDEM
    1. Installation and use
    2. Downloading 7.5 minute DEM's, see samples on file
    3. Image preparation
      1. Grid marks
      2. Elevation colors
      3. Crop as needed
  2. Building the Terrain
    1. Creating the plane and adding the displace modifier
    2. The DEM and adjusting displace parameters
    3. A "word" on mesh density
  3. The flight path
    1. Smooth, few curves, few vertices
    2. Adjusting the path
    3. Path constraint
      1. Add teapot and chase camera
      2. Path constraint parameters
        1. Path percentage
        2. constant velocity
        3. path follow
        4. bank and amount
    4. Tweak the path
    5. Preview
    6. Speed adjustment
