Shape

Replicating randomized shapes

Randomizing in the realm between d attributes:

<random attributeName="d"  
min="M 146,204 200,164  80,  0 z" 
max="M 200,204 250,164 300,200 z" />

Replicated random triangles -- layed out using horizontal translation

Triangles are triangles, but quadrilaterals (and higher n-gons) may have crossing lines.

Controlling paths by restricting certain nodes:

<svgr:random  attributeName="d" 
min="M 100,200 100,100 150,-20 200,100 200,200 z" 
max="M 100,200 100,100 150, 80 200,100 200,200 z" />

Random trees over random hillocks slightly displaced from grid points and given perspective.

This example illustrates some of the relative difficulty in controlling paths randomly. The tree template is controlled by
<svgr:random         min="M 0,0 v -45 l -40,-50 h -20 v -4 h 15 v -22 h 5 v12 L 0,-50 v -70 h 5 v 30 L 5 -44 35,-74 l-30,-30 v-20 h5 v 20 L 38,-82 l 20,-20 -20,-20 3,-3 20,20 v-20 h4 v20 L 25,-40 25,0 z"
   attributeName="d" max="M 0,0 v -35 l -10,-20 h -15 v -4 h 17 v -12 h 6 v12 L 0,-50 v -30 h 5 v 45 L 16 -40 35,-74 l-10,-10 v-20 h5 v 20 L 38,-82 l 20,-20 -20,-20 3,-3 20,20 v-20 h4 v20 L 25,-40 25,0 z " />

This is tedious and not very effective since, in order to have the branches not become triangular,

Perhaps our next project will be to undertake more complex syntactic studies of path subcommands, that would work nicely in combination with <random> and <replicate>.
