ARC HEIGHT VARIABILITY

EXTRUSIONS

The vector from the previous step is created in the x direction (y and z being 0.0) normal to the vertical orientation of the wall segments. It is evaluated using an expression x*(1+y/50*z) in which x is the variable arc height, y is the length of the vertical segment between two points and z is another variable. The expression adjusts the final height of the arc according to the length of the segment between two points by increasing it for larger lengths and decreasing it for smaller ones. That way variability in arcs’ heights is accomplished. Coefficient z amplifies the effect.

In the final step the arcs in every vertical line are joined and extruded, first creating a surface, then giving it thickness. Both extrusions are controlled with separate variables.
