Blender basics for AR
- use Blender 2.6 essential training
- go to Oasis – training – lynda.com – blender 2.6
- George Maestri
- forgettability – like any practice, don't go more than 24 hrs.
- using exercise files
- get the cheat sheet (dropbox)
- lots of non intuitive things about the interface
- helpful manual [2]
- good to have 2 screens when using tutorials
- need 3 button mouse, preferably with wheel
- for commands to work, make sure cursor is in window!!!
- Blender layout
- starts with one screen
- Ctrl/Alt(opt)/Q toggles quad view – very useful
views: 5 toggles between orthographic and perspective numbers toggle R, L, Top, front views
- zoom – use wheel, or ctrl middle click
- rotate POV (our view on the space, not the objects themselves) – use MMB/drag
- slide side to side/up down: shift click MMB
- slide L/R: Ctrl wheel
- slide up/down: shift wheel
- 3D concepts:
- Cartesian coordinate space– x, y, z (not all apps the same) – keep orientation x across, also axes embedded in grid (meaning of units can be set in R hand panel, under scene/scene (button2)
- right handed rule
*for making things to be transferred to the real world, set before beginning to create a scene
- object creation: start with graphic primitives
- (L click moves point of origin – R&W circle - for new object, shift C *to re-center)
- can see on view screen and in outliner upper R
- basic transforms: RTS
- certain options only available when you make a new object, Lower L panel
- resolution, size, etc.
- several ways of achieving:
- t,r,s keyboard keys
- upper L menu
- icons below view window
- can also move by snapping (object menu below, snap, snap selection to grid, to cursor, snap cursor to center, etc.)
- can modify entire object or, by using manipulators, modify certain aspects of them
- local and global (illustrate by creating cylinder, rotating, then translating in global and local)
- exercise: create mesh cylinder, rotate to 45 degree angle in x, translate to front left corner of grid
- polygonal modeling
- (there are also NURBS curves and surfaces – )
- modifications: rts points, edges, faces
- two edit modes: object, edit
- object – entire object; edit – component (points, edges, polygons)
