I'm a big fan of being stuffed with prey, and multi-prey scenarios in general, but I'm also very meticulous when it comes to details, and I really wanted a good way to visualize exactly how large my stomach would be with a given amount of prey. While I could find art references and intuit from there, there's a few problems; very few artists have specifications on the exact measurements of everything in the piece (not that I'd expect them to, or that they even should), and an accurate size is actually very difficult for the average person to get right, due to the unintuitive nature of the square-cube law, and the fact that the prey are not often liquids, meaning that they don't perfectly fill the space they're in.
So, of course the proper solution was to make a comprehensive tool that does all of the calculations for me. You can use it here. It's generally pretty self explanatory, but I'll do a rundown on the functionality just in case.
From the top down:
- Input Type: Selecting one of the checkboxes will make the box below them treat the number you've put in as whatever input type you've selected.
- Value display: Below the box are the values output by the tool. The one corresponding to the input you've chosen will of course be equal to the value in the box, and the others are calculated based on the value you input, as well as a few other variables.
- Prey Weight: This box should contain the average weight of the prey you're working with. This is used to calculate the total weight of the pred's belly, and more importantly, to estimate the total volume of each prey. Volume and weight are very strongly correlated and directly proportional, and weight is far easier to find data on than volume, so I went with that
- Buttons: Reset will reset the value of everything back to the default value, save for the current units and the currently input value. Metric/Imperial will switch to the other measurement system, though the contents of both of their input boxes are stored separately, so it won't automatically convert between them. No Digestion/Digestion will change the maximum value for the "Tightness" value (explained below) to include values above what is possible without either digesting or crushing prey, or back to only including normal values.
- Tightness: The slider here controls how tightly packed prey are. There'll be more details below if you care about the actual math, but essentially just know that this is the realistic range; To go below the loosest value on the slider, prey would have to be in a non-standard position that would make the numbers impossible to approximate, and similarly, going above the highest value would require melting, compressing, or neatly stacking prey.
- Rounding: This slider controls the number of decimal places to round to; regardless of this setting, numbers are computed using their actual value
*WARNING: MATH BELOW
Spoiler: show
This was only a very quick project, so I didn't create any kind of visualizer for the sizes, but this height comparison site has both people and the ability to create circles, which is what my visualizer would have been anyway.
Anyway, have fun!
