NewTek Lightwave 3D: Modeler II

  1. 1. Lightwave Modeling 3D Animation III
  2. 2. Making Objects  The modeling process  Start with primitive shapes  Modify the primitive shape  Use additional primitives to add or modify object
  3. 3. Making Primitive Shapes  Select the primitive shape you wish to make  Draw out the shape in one viewport  Makes a new 2D shape  Draw out in another viewport  Pulls the shape into a 3D shape
  4. 4. Making Primitive Shapes  How big do you want it?  Before you draw out your first shape, think about what you are making  Set the grid size to match the normal dimensions of the object you are making  Simply zoom in or out to set the grid size  Zoom tool or , & .
  5. 5. Let’s Get Started  Start up Modeler  Put your cursor in the top view, then press (,) and (.) to change the settings in the Grid window  Set the grid size to 500mm  2 500 mms = 1 meter
  6. 6. Let’s Make Something  Select the Create tab  Under Primitives select Box  In the Top viewport, drag out a box  6 grid marks wide  3 grid marks tall  Click on the + to center, if necessary
  7. 7. Let’s Make Something  In the Front viewport, drag up on your box @ ½ a grid mark  Click on the + and lift the box so the top of the box is 2 grid marks off the ground
  8. 8. Let’s Make Something  In the Right viewport, click on the + and drag the box to the center grid line.  Press Enter to make the shape
  9. 9. Let’s Make Something  In the upper right, select the top of the 2nd layer  Select the bottom of layer 1  This allows us to see what’s there without modifying it
  10. 10. Let’s Make Something  Select the Disc tool  From the Top viewport draw out a circle  From the Front viewport drag out the table leg so it goes just inside the table top  Click on Disc to make the leg
  11. 11. Let’s Make Something  Copy the leg (command C)  In the Top viewport, move the leg to the upper left of the table  Select Edit > Paste (command V)  Now you have two legs
  12. 12. Let’s Make Something  Copy again (command C)  Move the two legs to the right side of the table  Select Edit > Paste (command V)  Now you have all four legs
  13. 13. Put it All Together  On the Legs layer, select Edit > Cut (command x)  This puts whatever is in the layer into memory  Select the top of the first layer  Select Edit > Paste  All your pieces are in one place
  14. 14. Other Shapes  Ball  Great for making anything that needs to be round  Balls  Globes  Planets  Heads
  15. 15. Experiment with Other Shapes  Under Primitives select Ball  In the top view drag out a circle shape  In the front view drag out the 3rd dimension of your ball and press Enter  Press Command X to delete the ball
  16. 16. Other Shapes  Disk  Great for making tubes, pipes, pop cans, stems, ???
  17. 17. Experiment with Other Shapes  Select Disc  In the Top viewport drag out a circle  In the Front viewport pull out a cylinder shape  Click on Disc to turn off  Another way to make your shape beside Enter
  18. 18. Other Shapes  Cone  Good for anything that needs a point  Pencil tip  Missile head  Teepee  ???
  19. 19. Experiment with Other Shapes  Command X your Disc and select Cone  In the Top viewport drag out a circle  In the Front viewport pull out a cone shape  Click off Cone to make your shape
  20. 20. Other Shapes  Capsule Tool  Makes capsules  Rounded cylinders  Pills, water towers, rounder cubes, ???
  21. 21. Experiment with Other Shapes  Command X your cone and select More > Capsule Tool  Click and drag in the Top viewport to make the thickness of your capsule  Drag in the Front viewport to make the length  Press Enter to make the shape
  22. 22. Other Shapes  Toroid  Hollow disc shape that can be easily modified  Number of sections  How many sections make the circle  Number of sides  Number of surfaces that make the tube  Radius  How big the hole
  23. 23. Experiment with Other Shapes  Command X your capsule and select More > Toroid  In the Torus dialogue box leave the settings the same and press OK
  24. 24. Experiment with Other Shapes  Command X the Torus  Go back and make a new Torus, but this time change some of the settings and see what you can make
  25. 25. Experiment with Other Shapes  Reset the Torus settings:  Select the Toriod shape again and reset your settings:  Sections 36  Sides 16  Radius 1M  Start/End angle 0/360
  26. 26. Other Shapes  Gear  Under Primitives > More > More  Makes… gear shapes!  Lots of modifications available  Teeth  Teeth taper  Inner & outer radius  Thickness
  27. 27. Experiment with Other Shapes  Command X your Toroid  Under Primitives select More > More > Gear  In the dialogue box leave the settings the same, then press OK.
  28. 28. Other Shapes  Gemstone  Creates a multi-faceted diamond shape  Two handles  Changes the height of the top or bottom of the shape
  29. 29. Experiment with Other Shapes  Delete your previous shape  Select More > More > Gemstone  Click in the Top viewport to make the shape  Change the handles in the front view  Press Enter to make the diamond
  30. 30. Other Primitives to Check Out  Wedge  Like the Toroid, but with 4 surfaces
  31. 31. Other Shapes  Platonic  Makes multi-faceted closed shapes
  32. 32. Text Shape  Text  Allows you to make text as a shape  Helps to type in what you want in the Back viewport  Handles allow you to change the size and kerning of the letters
  33. 33. Experiment with Other Shapes  Command X to clear the viewports  Select Text  Change the Front viewport to Back  In the Back viewport, type in your name  Grab the handles to scale and kern your letters  Press Return when done
  34. 34. Experiment with Other Shapes  While you still have the Text tool selected, press N  Brings up the Numeric Text Tool box  Here you can set:  Font, alignment, axis, scale, center point, kerning, etc.
  35. 35. Other Shapes  Logo  Super easy way to make 3D text  Just plug in what you want, set the font, and you’re done!
  36. 36. Experiment with Other Shapes  Clear your viewports  Select Logo  Type in what you want, choose a font  Press OK
  37. 37. Assigning Surfaces  Before you save your new object, now is the time to decide which polygons in your shape need to be categorized as a separate part so you can color just that part  You can have as many surface categories as you like for your new object
  38. 38. Clean the Slate  Click File > Close All Objects  This will reset Modeler so it doesn’t remember all the shapes we made and makes assigning polygons easier
  39. 39. Make a Logo  In the Create tab select Logo  Set the font, type in your name and press OK  In the Modify tab rotate your name so it faces the front and move the name so it sits on the ‘floor’
  40. 40. Select the Front and Back Polygons  Select ‘Polygon Mode’  In the Left viewport, hold the Option key and draw a circle around the front of your text  Hold the Shift & Option key, then also select the back of your text  Selected polygons are now highlighted
  41. 41. Choose a Color  Press Q  Shortcut for ‘Change Surface’  In the Name section, assign the new name ‘Text Front & Back’  Turn off ‘Make Default’  Click on the color box and choose a color  Press OK
  42. 42. Select the Side Polygons  While still in Polygon mode, click in the lower left to deselect the current polygons  In the Left viewport drag your mouse up and down inside the sides of your text to select only the side polygons  Make sure you don’t accidently select the front or back
  43. 43. Choose a Color  Press Q  In the Name section, assign the new name ‘Text Sides’  Click on the color box and choose a color  Press OK
  44. 44. Check Your Work  In the Perspective view, zoom in and rotate your view to make sure the polygon surfacing turned out the way you planned.
  45. 45. Time to Save Your Object  Select File > Save Object  In the Objects folder, create a new folder called ‘My Objects’ and save your new object there.
  46. 46. Save a Copy for your Homework  Select File > Save As  Select the Desktop and make a copy of your object there  Attach it to an email to me
  47. 47. Lightwave Modeling 3D Animation III
