5.1 Introduction

Originally this software had constants only. You can find constants of formulas or differential equations. Typical constants are presented below:

Properties of constants 

In this picture d is real vector and m is real value. Later constants had begun to use for feedback. Architecture of feedback is presented on the following picture:

5.2 Example 1. Processing of images

Processing of images needs feedback. It sends coordinates of pixel and then receives a color of pixel. Typical situation is presented below:

Image processing 

The Picture uses Root anf F. Its editor of properties is presented below:

Image processing 

In this picture F.x and F.y correspond to aliases of coorginates of pixel. Root.Formula_1, Root.Formula_2 and Root.Formula_3 correspond to red, blue and green color component of pixel. You can find aliases F.x and F.y at the left right corner on editor of properties of F:

5.3 Example 2. 6D dymamics

The description of 6D dynamics of solid body requires feedback. Forces and torques act on solid body. Values of forces and torques depend of motion parameters of the body. Otherwise derivations of motion parameters depend on forces and torques. This situation is presented on the following scheme:

Solid body feedback 

Motion parameters of solid body are defined as aliases:

Solid body motion parameters 

Forces and torques are defined as output parameters of dataflow:
