dilatation en y
Like all linear transformations that command is in 2 modes:
direct and matrix.
Y dilates the object of (c) with respect to its center of gravity.
poi(x,y,z): with respect to point (x,y,z).
vertex(s): vertex s.
dily(1.5) vertex[1,5] vol(1,3); y dilates vertices (1,2,3,4,5) of
volumes 1 and by (1.5) with respect to point (100,100,200).
dily(2) var("w")poi(100,100,200); y dilates variable named w by (2)
with respect to point(100,100,200).
3) dily(.5) eye view(1): y dilate by .5 the eye of view(1) with respect to origin.
dily matrix vol(id)
Returns the y expansion coefficient of the matrix of volume id.
Y expands the volume id by modifying its matrix.
ini: addresses the basic processing.
