• Automate
lets you create a large number of renderings at once
²Note
that most (but not all) number entry boxes have slightly raised borders:
²Such boxes can use an expression with the variable ‘t’ when Automate is used:
åTurn Automate on
åEnter some small number in the Frames control (say 5)
åEnter 70+5*t in the Roll control, then press Compute
åThe dataset will be rendered with the variable ‘t’ set
to 0, 1, 2, 3, 4 in turn
ØThat is, t will run from 0 to one less than the number of Frames, and all the raised-border boxes that use expressions with
‘t’ will be evaluated
prior to each frame being rendered
åIn this example, this will result in a sequence of
views of the dataset from different
roll angles 70o, 75o, 80o, 85o, 90o
åCan also use ‘t’ in cutout parameters to make cutouts
depend on ‘time’
Ø2 cutouts, Left of=10+3*t and Right of=-10+3*t will
produce a 20 mm thick slice
that slides leftwards as t increases
åCan use ‘t’ in more than one raised-border box
simultaneously to make complex
animations (e.g., Roll and Cutouts together)
åPut cursor in raised-border box and press Enter to have box reset to last numerical value used by Automate
With raised border
Without raised border
