Method

1. Provide Perplexity the dimensions of the nebula/star cluster/state's established coordinates of its central plane:

A closed asymmetrical shape is represented on a 2D map with the following (JSON format) coordinates. Generate that 2D representation as an image with a defining boundary.

Attach those points; ex:

"points":[{"x":-31.16,"y":10.75,"z":0},{"x":-32.15,"y":8.55,"z":0},{"x":-29.8,"y":7.14,"z":0},{"x":-27.71,"y":10.75,"z":0},{"x":-26.6,"y":12.82,"z":0},{"x":-28.14,"y":12.51,"z":0}]

Confirm the provided image roughly matches the actual shape in SST.

2. Determine the relative center of the the nebula/star cluster/state:

What is the coordinate for the geographic center of this shape?

3. Determine the greatest length between established coordinates of the nebula/star cluster/state:

What is the longest dimension that exists within this shape?

4. Determine the upper and lower z-axis values, based on that greatest length; modify as necessary/pertinent.

5. Determine the approximate volume by the central plane's established dimension and the greatest length doubled:

Calculate the volume of a large irregular diffuse nebula (not bipolar) with a fractal boundary and vertical extent of ## units (crossing through the geographic center), using the defined cross-sectional area as the base.
