Place rule – single CENTRE parameter placed shape in the middle of the region
Attributes
could be set using values of other attributes
for instance set(a, 20) set(b, a)
new attribute “elevation” specifies the amount to extrude upwards (push/pull)
new type attribute “border” – sets stone-like material to the region and elevates 6 units up
Scatter rule – samples that are placed along the edge (EDGE_SELECTION) are jittered by a small amount to make them look more natural.
Grammar Changes
place rule – third selector block is optional (will use the first for the second shape).
Technical Details
Attribute system is re-written. Global attribute evaluation is performed after the entire Rulefile is parsed (thus the order of assignment is not important). Shape attributes are evaluated during rule application
Grid rule fixes: path widths for non-rectangular input regions are evenly adjusted.
