Icon and Logo designs...

1. Odd shape, not immediately evident how it was made.
2. Sweeping curves, leading into more complex form.
3. Lit from the bottom, to help hold the eye.
4. Overall shape devolves well to low-color, icon  sized images.

BentFX 1.0 functional goals...

1. Designed from the ground up to be modular and extensible, through both C++ API, and Python Scripting.
2. Expose 3D & 2D OpenGL contexts.
3. Object oriented design allowing C++ programmable object types and tools. Initial primary 3D object types will be subdivision polymeshs and spline curves. Yet base object class should be overloadable to provide NURBS, height maps, what have you.  
4. User space coordinate systems, including rectangular, spherical, conical and cylidrical coordinates.
5. Base toolsets will be box modeling, extrusion on curves, arrays(arrays of arrays), mirrored meshes.
6. more to come...

Design goals...

1. GUI implemented in OpenGL, using GiGi. It is a mature ogl gui toolkit. Given the other choices it seems to be the choice for an entirely ogl, style-able, xml-able toolkit.
2. Interface will be as mouse driven as resonably possible.
3. Among the first 2D modules will be texture slicer for easy skin creation.
4. more to come...
