    • C-vcontrol-
    • S- → shift-
    • Alt- → Alt-
    • Spc → space bar
    • Tab → tab key
  • split region, by using middle mouse button on dividers between regions
    • setup 4 pane view
    • menu > system & opengl >
    • edit methods > mesh undo > 64
  • using the configuration area between the titlebar and viewport )
    • hide menu, keep working
    • num. 1(z,x) 3(z,y) 7(y,x)
    • 1(z,x) 5(perspective mode)
  • viewports )
    • C-u to 'save user defaults'
  • C-'up-arrow' > maximize viewport
  • spacebar to bring up mesh menu (eg. add > cube)
  • mmb to rotate
    • shift-mmb to scroll across the screen
    • mw to zoom, C-mmb
    • edit mode enables editing of mesh
  • Tab toggle edit/object mode )
    • rc to select objects in the oops
  • oops schematic, under left menu icon in viewport )
    • 'u' to undo

in edit mode

  • 'a' toggle select all/none
    • 'x' delete
    • lc to accept, rc to not-accept the changes
  • 'g' to grab a vertex after rc to select )
    • S-rc to select a face

object mode

  • tab to enter
    • mmb to spin,
    • 'z' to view rendered
    • red/white point is pov rotation
    • pink dot is object center
    • rotation menu > select point to rotate view around

modeling

  • select by draging box around object (lmb/rmb)
  • 'b' key to get into 'box mode' )
    • space > add mesh > plane
    • 'a' to select
    • 'e' to extrude
    • 's' to scale
    • 'b' box-mode select
  • add mesh > circle > verticies 16
    • extrude/scale/etc
  • 'SubSur' (in panels section) to subdivide surfaces
    • 'n' for transform properties pop-up menu, Shift to edit numbers
  • '4' and '6' to rotate view (vertical)
    • '2' and '8' to rotate view (horizontal)
    • rc to select which object is editable
  • 'p' to seperate a form (selected verticies)
    • S-k cut tool
  • make a cube,
    • S-k to cut the cube
    • select one half (in object mode)
    • move the 2 halves apart
    • select each of the vertecies of the open side
    • 'f' to create a face joining the selected vertecies

normals

  • normals as direction a face is pointing
    • C-n to force normals to point 'outward'

complexifying meshes

  • edit mode
    • select > mesh tools > subdivide
    • select face, extrude, duplicate (C-d)
    • mesh tools > rem doubles
    • Alt-M to merge vertices
  • subsurfacing is for display only
  • smoothing a mesh
    • mesh tools > subdivide > smooth
  • 'm' to move an object ot another layer

fuzzy select

  • single vertex on a complex mesh * 'o' (adds menu icon for 'smooth/sharp falloff') * 'g' to grab a circular selection from a vertex

scaling

  • using 's' for scaling, the mmb can be used to fix values, to scale non uninformly

warping

  • keycommand?

surface using bezier curve

  • edit mode
  • spc, add 'bezier curve'
  • 'g' to grab/move control points
  • (repeat if necessary)
  • convert to mesh
  • object mode (tab)
  • spc > convert object type > mesh

building meshes from a single vert

  • reduce an object to a single point
    • C-lc to add points
    • Alt-M to merge
    • smooth/etc
    • S-f to 'fill' with face (vs 'f' for a single face)

make a wineglass

  • make the profile of half a glass using a sequence of single verts
  • check the object center is at the origin
    • object mode, press 'n', set to 0s,
    • 'center new'from the mesh option panel
  • move profile to align with the axis
  • select the desired 'screw' (degr:360), 'spin' (steps:18) 'spin dup' (turns:1)
  • click in the xy view
  • 'remove doubles'
  • 'subdivide'
  • 'smooth' etc+

bending

  • forming a smooth bend, rather than a sharp corner
    • select the verts to bend
    • press 'o' for 'fuzzy select'
    • 'r' to rotate, mw to select the radius of rotation

animation

  • select 'ipo curve editor'
  • object mode
  • add some objects
  • menu on the right of the ipo view are the 'operations' that can be performed
  • time axis (horiz.) vs. 'value' axis (vertical)
  • add keyframe
    • in object mode
    • 'i' to insert key
    • select 'loc'
  • make change(s) to object
  • insert new key frame (as above)
  • check the splines have changed
  • animation window has 'point' (edit) and 'curve' (object mode
  • edit points in 'point' mode, can use editing/select tools.

camera

  • in 'top' view
  • spc, add > camera
  • press '0' to see what the camera is looking at

rendering
