Challenge #251: Lunacy

A solution to last week's challenge can be found here.

The word lunacy has its origins in the latin term for the moon (luna). For this week's challenge, we will embark on a little lunacy of our own and try to approximate the phases of the moon in Designer. Transform the 7 circles in the Input data file into polygons that resemble the assigned lunar phase in that row.

My crescents look better than my gibbous but I couldn't get it to look any better.

My gibbous moons could use some work but not terrible:

I tried too hard to copy the output exactly which resulted in a massive workflow... Although, I did create a cool batch macro that will create the points of a circle to make it more dynamic.

My first try to a weekly challenge. My crescents look better than the gibbous, but a good try nonetheless.

I'm sure there is a simpler way to do this. Looking forward to checking out other solutions.

I really wanted to get the curves right so I did a bit of math to figure out the proper shape for the mask for the crescent and gibbous. I was a bit lazy and didn't put the calcs in the workflow, just used the mask offset and radius ratios that I calculated manually.

This challenge really stretched me, I don't often work with spatial data.

Tricky Challenge 🙂 not sure I have a particularly elegant approach - and it involved a bit of trial and error

Very fun spatial challenge!

Spoiler

I had problems with some of the shapes until I realized it was the Earth's shadow I was cutting from the moon which may be larger. So experimented with radius and here is what I came up with. Also a bit messy workflow as I did each spatial process one at a time.

This was fun, thanks for the challenge.
Not particularly happy with the long formula, but...

Quite a long formula

Colorful moons here-- I think they came out good with the exception being the gibbous ones, which I will need to see the official solution for a better approach

These challenges seem to be coming in the week after I do something very similar. Love utilizing the spatial tools! See spoiler for details.

Spoiler

The week before this came out I was having a go at modifying state polygons, particularly Alaska because it uses both sides of the world map and I needed to isolate the state to overlay it elsewhere. I used a similar method for the half moons in this challenge by splitting the polygon to points, using a browse to identify the points I wanted to keep and then sampling or filtering before rebuilding the sequence polygon.

The other four phases were done by translation and for the gibbous, additionally dilation, then using the spatial process tool to cut or intersect.

Here is my solution for challenge 251, there must be a better way to solve it!

Tried two approaches... one using a sine function to model the 'altered' portion of each moon phase, and a second using the spatial process tool to 'cut out' the proper shape for each phase. approach 2 was closer to the provided output for the challenge.
