Three new primitives plugin for shell, spiral, gear - PhilippePoupon - 03-05-2018
Hello, I made three primitives plugins.
It is an evolution of plugins already existing for spirals and cylinders with more parameters.
There is a plugin for spirals with logarithmic spirals, an other one for gear and one to make shells.
Install into wings3d_2.1.5\lib\wings-2.1.5\plugins\primitives
zip file for 2.1.5 binary
zip file for sources

Nice to see someone else playing with Erlang.
Helix can replace Spring;
Gear option would be removed from Cylinder dialog;
Shell is a nice addition, but I don't see a use to Invert Normals. That can be achieved for any object in Body selection mode using the command Invert.

PhilippePoupon,
Thanks for creating a shell plugin. Would it be possible to add a wall thickness option. The Intrude command makes it possible to hollow out the shell but with a very thin wall.
Also, would it be possible to add presets for various types of shells?
Here are a couple of programs that can produce sea shells for reference.

Hello,
I try to add thickness to the shell but actually it's don't work ( I 'm a beginner in erlang ! )
I'll try to improve it all when I have more time
This is why I add the "Invert Normals" to create the inside of the shell !
If you want to hollow the shell you can use this trick :
you must create a second shell with same parameters except for section hight and section length who must be smallest, and invert the normal , this is the inside of the shell.
Then you must select the larger section of the two shell and use bridge .
For example:
First Shell for external :
Second shell smallest and inverted for inside :
Use bridge !
The result:
The plugins for the new version 2.1.6

PhilippePoupon,
Thanks for the step by step on adding thickness.
I don't think any of the shell making programs I have tried have had the option to control the thickness. Hopefully you can get it to work in the plugin in the future.
Thanks,
oort
