SOLAR SYSTEM EXERCISE
image.jpg
It's time to create your own Universe!

Create Scale Models
  1. Start up Anim8or
  2. Choose the SPHERE tool and drag from the center of the X and Y axis to create a sphere
  3. Double Click the sphere to examine it's PARAMETERS, and set the following
    1. Name to read "Earth"
    2. Location to 0, 0, 0
    3. Size to 12.7
  4. Use the SPHERE tool to draw the moon off to one side; double click it and set it's name, and it's size to 3.5
  5. Use CTRL-R to t
    urn on ARC-ROTATE mode, and hold down the WHEEL MOUSE BUTTON
    1. WHEEL MOUSE Drag from right to left WITHIN the green circle to zoom out; or left to right to zoom in
    2. Use the RIGHT MOUSE BUTTON to "strafe" to the side
    3. Use the LEFT MOUSE BUTTON to rotate around your objects
  6. Tap the [5] key on the NUMERIC KEYPAD to return to the FRONT view
  7. Draw VENUS and Mars to the left of the Earth using the diameters in the chart below
  8. Draw Mars and the OUTER planets to the right of Earth

Add Textures
  1. Open up the MATERIALS Editor
  2. Double click a NEW spot and edit the new material
    1. Add a meaningful and unique NAME
    2. Click the TEXTURES button
    3. Click the [...] button beside "ambient" and LOAD an image into the material
    4. Select the new texture and hit OK - Repeat these steps for the "diffuse" setting
    5. Click OK all the way back to the main screen
    6. Select your object, and material, and click the APPLY button

Add Saturn's Rings
We need to make a "ruler" to measure the size of Saturn's rings. We'll do this by build a couple of cubes to precise size below Saturn's sphere, then trace the shapes we need over top of that
  1. Turn on GRID SNAP (Ctrl-G)
  2. Double Click Saturn and set it at an even rounded off X location (ie x=300)
  3. From the FRONT view, draw a cube way below saturn and locate it as follows
    1. LOCATION x=300 (or the same as Saturn was)
    2. X Size = 280.6
    3. Y Size = 20
    4. Z Size = 280.6
  4. Use Materials and colour the cube with one of the planets textures
  5. Draw a SECOND cubeovertop the first with the following dimensions
    1. LOCATION x=300
    2. X Size = 134.6
    3. Y Size = 20
    4. Z Size = 134.6
  6. VIEW the model from the TOP
  7. Use BUILD | PRIMITIVES | N-Gon to set the value to 32
  8. From the TOP view, draw an N-Gon from the CENTER of the planet outward, with diameter that matches the 280.6 cube, and ANOTHER N-Gon that matches the 134.6 cube
  9. Delete the cubes
  10. Select both (right mouseclick) and use BUILD | JOIN SPLINES
  11. Use the BUILD | EXTRUDE tool
    1. Select the Y Axis
    2. Set Length to 2 and Segs to 1
    3. Turn ON Caps for Start and End
    4. Click OK
  12. Open your MATERIALS and create a RING texture the way we made textures back in the last tutorial. Set the TRANS (Transparency) setting to 0.7. Apply it to the ring object - don't worry that it doesn't look quite right yet.
  13. Use the UV Tool - Say YES to enable texture
    1. Use the LEFT mouse button VERTICALLY to stretch the texture until it fits from top to bottom
    2. Use the WHEEL button HORIZONTALLY to stretch the texture until it fits the width
    3. Use the RIGHT mouse button to center the texture so it matches the edges
    4. Click the SELECT tool to leave UV mode
  14. Try using ARC ROTATE (Ctrl-R) to check out your model!
  15. Select both the RINGS and the SPHERE and use BUILD | GROUP to join them together
  16. Adjust the location of your planets if need be so they don't collide!
