3/ Mother shape declination

Declination 1

The mother shape is situated in the middle in red, around this are certain shapes in which I have varied the F1 and F2 parameters. The declination thus developed in a two-dimensional space. By varying the third parameter, the declination will be produced in a three-dimensional space which can still be illustrated although difficult to comprehend. But, by varying all three parameters, the declination is then produced on a three-dimensional space Nevertheless, I have taken a few sufficiently varied volumes out of this three dimension (see exemples sheet) that will enable you to have an idea of this family.

Declination 2
This sheet represents six Mother shapes of different frequencies. In drawings 11 and 12, the forms have been put in identical size. In drawings 21 and 22, the triangles have the same lengths.
We see that like in the CSM family, not only are these forms likely to vary in their proportions, but are also prone to vary in size…and always using one module..!
