033_idealhouse_sineroof

• Start with two ellipses, adjust their major/minor axes
• Divide both ellipses into N1 points
• Decompose points into X, Y and Z coordinates
• Take the domain of the curves and run it through a sine function
• Create new points that take the old X, Y, and add (a potentially negative number) the result of the sine function into the Z coordinate.
• Draw lines between the points that belong to the inside and outside ellipses
• Count the number of lines
• Create a list of booleans which is number of lines - N2, TRUE and N2 False
• Shift list of booleans by N3, wrapping on
• Cull the list of lines by booleans
• Decompose remaining lines into start(P1) and end(P2) points
• Compare start and end points Z coordinate
• If Z1 > Z2 then draw SDL (start, direction, length) line of N4 length along vector P1->P2
• Else draw SDL line of N4 Length along vector P2->P1
• Decompose P2 into XYZ coordinates, make new point using P2 XY and P1 Z
• Create unit vector between P1 and P2b
• rotate vector .5pi radians
• set amplitude to N5
• Extrude SDL lines by respective vectors
