Open ShelMi opened 8 years ago
It does indeed model a sphere. However, often times, that's exactly what people are printing on. Also, we have learned over the past couple of years that there is tremendous variation, even in just chicken eggs. :)
If we add support for proper egg shapes, then...
None of these is to say that it shouldn't be pursued, just some food for thought.
Points taken.
I have a substitute suggestion which I have been using for a few days, and I like having the additional flexibility that comes with the options in this substitute "advanced stretch".
I still am thinking about a user-friendly method for un-egg-shaping the plot, but that will have to wait for a future day. 8^)
I needed greater-than-integer percent precision when I was doing a stretch, so have a new version with no other changes than allowing up to 4 digits past the decimal point in the expand percent field.

[EDIT] Just realized that 4 digits was overkill - changed from 4 digits to 2 digits precision in version 03.
I would suggest splitting your GUI into at least two tabs, to make the interface more compact. Perhaps a "description" and "help" tab in addition to the main "stretch" tab.
This is not, by a long shot, a big deal - but I think the stretch algorithm could have just a little bit of refinement added to it. The current version, nice as it is, nonetheless maps the stretch function as though the print were on a sphere.
I wonder if the data/methods presented at http://www.takayaiwamoto.com/Egg_Draw/Real_Chicken_Egg.html might be used to do a more accurate mapping of SVG coordinates to the egg ovoid. A rough test, based on the below image, shows that the differential error between a sphere and the large end of an egg may be as much as 33%.
I say this in the full realization that +/- nobody will really notice the difference, but I still would be happy to take a shot at it. If further data presents itself, one might even consider having separate settings for ostrich, duck, chicken.
