NewTek Lightwave 3D: Working in 3D Space

  1. 1. Animation IV Working in 3D Space
  2. 2. Loading an Object  Loading an Object  In the Items tab  Object button  Shortcut +  Object Layer  If the object was saved in separate layers you can load the layer items separately as separate objects
  3. 3. Loading an Object  From Scene  Neat trick of loading an object from another scene  Brings in all the animation that came with the object  Can even import the lights that were used in that scene if you want to
  4. 4. Let’s Get Started  Start up Lightwave 3D  Select the Items tab  From the Load section, select ‘From Scene’
  5. 5. Let’s Get Started  From the Aviation folder select ‘MustangLowRes’  In the Load from Scene dialogue box, scroll down to the Lights folder and select all 3 lights  Don’t select the camera  Select OK
  6. 6. Let’s Get Started  Switch to Camera view (6)  Drag the timeline slider and notice that the airplane already has motion applied to the object without you doing anything!  All you need to do now is move the airplane around
  7. 7. Working in 3D Space  Direction  X value – left & right  -X = going left from center  +X = going right from center  Red arrow
  8. 8. Working in 3D Space  Direction  Y value – up & down  -Y – going down from center  +Y – going up from center  Green arrow
  9. 9. Working in 3D Space  Direction  Z value  (Assuming the camera is in front of your object)  -Z = Moving towards the camera from the center  +Z = Moving away from the camera from the center
  10. 10. Choosing What to Move  Current item pop-up menu  Sometimes an object is made up of one piece  Cow for instance  Sometimes an object consists of several pieces  The Mustang airplane  Choosing what to move is VERY important
  11. 11. Choosing What to Move  Who’s the boss?  When an object is made of of several pieces (or other objects) typically, one object controls all the other objects  This is called parenting  Whatever the parent does, the children do the same thing
  12. 12. Moving Things Around  Press M to bring up the Motion Properties dialogue box  Click on the Parent Item pop-up menu  Notice that ‘m-body11’ is the top dog or parent for the whole object  If you want to modify the whole object, this is what you choose
  13. 13. Moving Things Around  Select the Modify tab  Select the Move button (t)  In the Current Item pop-up menu select ‘m_body11’
  14. 14. Moving Things Around  Using the Camera view and Top view move the Mustang away from the camera and to the upper left
  15. 15. Working in 3D Space  Rotation  Heading  Rotating along the horizontal axis  Y axis  Red circle
  16. 16. Working in 3D Space  Rotation  Pitch  Rotating along the X axis  Nodding up and down  Green circle
  17. 17. Working in 3D Space  Rotation  Banking  Rotating along the Z axis  Rocking back and forth  Blue circle
  18. 18. Moving Things Around  In the Modify tab select the Rotate tool  Select the bank, pitch and horizontal circles to straighten the plane so it appears to be heading toward the camera (you)
  19. 19. Moving Things Around  In the Auto Key Modifier pop-up menu choose Auto Key Modified  This allows us to modify the object we loaded from a scene that had key frames already added  Move the timeline slider to 120
  20. 20. Moving Things Around  Select the Move tool  Using the Camera and Top view, move the mustang closer to the camera and to the upper right.  You should see a motion path from frame 0
  21. 21. Moving Things Around  Move the timeline slider to 60  Halfway through our animation  With the Move tool, select the green arrow and make the mustang dip low
  22. 22. Working in 3D Space  Size vs. Stretch  Size  Scaled equally along all axis points  Stretch  Allows you to scale each axis independently
  23. 23. Working in 3D Space  Sizing  Simply drag left and right on the object to make the object smaller or bigger  Can also use numerics window to set an exact value
  24. 24. Working in 3D Space  Stretch  Red handle  Stretch along the X axis  Green handle  Stretch along the Y axis  Blue handle  Stretch along the Z axis
  25. 25. Add a Little Perspective  Move the timeline slider to 0  Select the Size tool and scale down the mustang to 0.500
  26. 26. Add a Little Perspective  Move the timeline slider to 120  Select the Size tool and scale up the mustang the 1.250  Drag the timeline slider back and forth to check out the animation
  27. 27. Aligning to Path  Rather than setting all the heading, pitch and bank settings manually, have the object Align to Path instead  This option works only if the object was made facing toward the +Z plane  Our mustang faces the wrong way so this won’t work 
  28. 28. Isolating Motion  Turn on or off axis points using the numerics box  Only the control handles still active appear on the object  Use the sliders for the axis point you wish to change
  29. 29. Add a Little Perspective  Switch to the Top view  Go to each key frame and align the horizontal motion to follow the path
  30. 30. Add a Little Perspective  Switch to the Camera view  At each key frame change the pitch value to follow the motion  Use the P value in the numerics window  Click on the green circle
  31. 31. Add a Backdrop  Easy way to fill the background of your animation with:  Solid color  Color gradient  Image
  32. 32. Add a Little Perspective  In the Windows pop- up menu select Backdrop Options  In the Backdrop tab, check the Gradient Backdrop  Zenith to nadir color sets the range of color from top to bottom
  33. 33. Add a Little Perspective  This gradient actually works well the way it is for our sky so after checking the box, close the window  Press F9 to check out a frame of your animation
  34. 34. Making an Animation  Lots of different types of animation outputs in Lightwave  We use only one  QuickTime (.mov)
  35. 35. Make an Animation  Select the Render tab  On the left select Render Globals
  36. 36. Animation Settings  Select the General tab  This sets what part of your scene to render  Check the settings:  First frame = 1  Last frame = 120  Step = 1  Leave off everything else
  37. 37. Animation Settings  Check out the Render tab  This sets what Lightwave should render  Shadows, reflections, transparency, lens flares and other effects
  38. 38. Animation Settings  Check out the Camera tab  This allows you to change the camera focal length, render dimensions, motion blur effects
  39. 39. Animation Settings  Check out the Lights tab  This allows you to change the settings to any of the lights in your scene
  40. 40. Animation Settings  Check out the Output tab  This sets how you wish to save your animation  Lots of options, but we only need one  QuickTime (.mov)
  41. 41. Animation Settings  Check the Save Animation box  Click on the Type pop-up window and choose QuickTime (.mov)  Click the Animation File box  Name and save your animation file to the desktop
  42. 42. Animation Settings  Once your Render Globals settings are set, click Render Scene (F10)  The Render Status window comes up and shows you each frame as it’s rendered out.
  43. 43. Save a Copy of your Scene for your Homework  Select File > Save Scene As  Save the scene file (.LWS) to the desktop  Later, you will attach this file to an email to me
