Modifications like these from an existing application to a new one probably accounts for 90% of the model
development of AnyBody users. However, in some cases it is not possible to find a good existing application,
and it can be advantageous to build your own model from the body parts in the repository.
The next lessons, starting with Lesson 5
, deal with such a case.
Lesson 5: Starting with a new model
In the previous lessons we have been constructing our model by modification of an existing application,
namely the Standing Model. In some cases it may be difficult to find an existing model that is sufficiently
similar to what you want to obtain. In such a case it can be reasonable to begin the modeling project from a
new model rather than an existing model. This is what we shall explore in the forthcoming lessons. We shall
design a model of a single leg stepping on a pedal. Such a model is much more numerically efficient than
the model of the previous lessons, and therefore it makes no sense to begin the project from the standing
model as we did before.
Let us first review the structure of the repository in slightly more detail. One of the objectives of its structure
is to enable a clear division between the body parts and the applications we hook them up to. This comes
through in the data structure of the model we are going to construct. Here is a brief overview of the
principles behind that structure.
