Essential Geo for Softimage

This addin provides twelve geometry primitives to a submenu of Primitive->Polygon Mesh->EssentialGeo. It is distributed under the terms of the Creative Commons Attribution-NoDerivs 3.0 Unported license which can be found at

These are mostly single-poly objects expected to be used as basic building blocks of more complex geometry. Most parameters can be animated and the responsiveness of C++ based code provides for fast feedback while you experiment with the settings.

The geometry primitives include:
Fractal Ring
Fractal Strip
Gear Mesh (Ring)
Gear Strip
Rounded Poly
Rounded Rect
Smooth Star
Transform Strip
Wave Strip

Here is a video that demonstrates most of the available features.

Please enjoy this tool with our compliments. To install, download the attached .xsiaddin file and drag it onto your running Softimage window. It includes both 32 and 64 bit versions for Windows. Unfortunately it does not include Linux builds. It was developed & tested with Softimage 2012SAPx64 & x32, however users have reported it works with Mod Tool 7.5 so most Softimage users should probably be able to use it.

NOTE: If you are unable to get it to work immediately after dropping the .xsiaddon file into Softimage, this might mean that your system does not yet have the Visual C++ 2010 support libraries installed yet. They can be found here:

Microsoft Visual C++ 2010 Redistributable Package (x86) -
Microsoft Visual C++ 2010 Redistributable Package (x64) -

Here are some of the primitives you will find in the Primitive->Polygon Mesh->EssentialGeo menu once the addin is installed.

If you've read this far you might be wondering about the name. Is it truly "Essential"? No, not really. However I do use these primitives with almost everything I do so, for me, yes it is. That's what I wrote it! :) If there is enough interest in more primitives, I might be tempted to spend a little more time on the tool to provide more of these basic building blocks for constructing geometry so please feel free to encourage me.
