Improve function for brick-seams

[sttng]

Current function is based on scaling the bricks by a factor in %.

# Random Scale for brick seams
out.write("\t\tScale {0} {0} {0}\n".format(random.uniform(0.9925, 1.000)))

This means that larger bricks are scaled by more absolute milimeters then small bricks (i.e. the absolute value is larger for larger bricks then compared to for smaller bricks, even the scaling percentage is the same).

Investigate if there is a possibilty to have a similar absolute value by using maybe Bounding or GeometryBounding to adjust the scaling factor accordingly.

  <Bounding>
    <AABB minX="-0.939257" minY="-2.40269" minZ="-0.001587" maxX="1.59363" maxY="0.831503" maxZ="1.78367" />
  </Bounding>
  <GeometryBounding>
    <AABB minX="-0.939257" minY="-2.28474" minZ="-0.001587" maxX="1.59363" maxY="0.831503" maxZ="1.78367" />
  </GeometryBounding>

Idea:

calcualte

maxlist = [abs(minX - maxX), abs(minY - maxY), abs(minZ - maxZ)] 
maxlist.sort() 
maxBounding = list1[-1] 
scalefact = (maxBounding - 0.1 * random.uniform(0.9925, 1.000)) / maxBounding
# Random Scale for brick seams
out.write("\t\tScale {0} {0} {0}\n".format(scalefact))

In addition one could also randomly (maybe 50% chance) add a rotation around the x-axes by +/- 1-2 degrees:

if random() < .5:

• scalefactor calculation based on Bounding implemented ✔️
• random rotation still pending
