ADDON. Version 0.3. Released on 2019-Feb-23. Provides 44 components. Created by Lorenzo Greco. Features 1 video tutorials.
Dodo is a collection of tools for machine learning, optimization, and geometry manipulation. Regarding AI, it features neural networks, gradient descent, stochastic gradient descent and swarm optimization. Dodo has tools for scalar, vector and tensor fields manipulation which can be visualized using isosurfaces. Some components are implementations of papers, you can find more info and reference in their html description.

Construct Tensor Field (ConstructTF)
Constructs a tensor field
Custom Field (CustomField)
Generate a user-defined vector field
Deconstruct Tensor Field (DeconstructTensField)
Deconstruct a tensor field into a connectivity mesh and a list of tensors
Discrete Field (DiscrField)
Generate a continuous field from a discrete vector set
Field From Mesh (FieldFromMesh)
Generates a field based on a mesh's principal curvature
Field From Surface (FieldFromSurface)
Generates a field based on a surface's principal curvature
Field Potential (FieldPotential)
Provided the field is conservative, this calculates the potential in each pointas the negative of the work done by a particle from the sampling point (A) to the source (B)
Image Charge (ImageCharge)
Create a field due to an image charge
Point Trajectory (IntegFieldPoint)
Find the trajectory of a point in a field
Integrate Tensor Field (IntegrateTFMesh)
Integrate Tensor Field on Mesh
Path on Object (PathOnObj)
Integrate a field using an object as a constraint
Rotate Tensor Field (RotateTF)
Smoothen Field (Smoothen a field)
See html help in the component
Iso-Potential Surface (IsoPotSurf)
Calculates the iso-potential surfaces of a field
Tensor Field - Vector (TFtoVF)
Calculate a vector field from a tensor field and a single direction The resulting vector will be V(x) = TF(x) * D, where M is the tensor field in a point and D the direction given
Tensor Field - Component (TFtoVF2)
Creates a vector field by choosing a component of the Tensor Field. By default it takes the first direction. Right-click on the component to change that.
