Fata Morgana  the system of simulation and analysis of threedimensional multiparametric surfaces.
Basic purpose  simulation and the analysis of the objects, which can be threedimensional surfaces.
Fata Morgana is the SAMARA's module, but it can be used as the independent system which provides decision of the wide circle of tasks, and be used together with other applications AutoCAD in the most different branches.
The models of system Fata Morgana are the threedimensional surface, which can have an arbitrary quantity of other parameters (for example: seam thickness (or the roof's mark of the mine workings), the content of the component or humidity of rocks, gas content, density, mechanical strength, etc.),what can be expressed by the number. Actually, this model consists as of the several networks (according to the number of parameters being present in the model). So, the simulation object can be for example, the earth surface, quarry, geological or ore layer, roads and reservoirs. The system allows to carry out simultaneous processing of any quantity of models (limited only by the computer's resources), that offers the possibility of the simulation of the geological structure of territory.
The system's name  Fata Morgana  reflects the characteristic of the technology of model's formation and editing in the system. So, the networks constructed by it are not the AutoCAD's objects (do not load figure with an great quantity of objects, that's why the work with system is much easy and rapid), but network's phantoms (mirages, ghosts) are present in the session (visible or invisible  at will of operator), that allows to use its data. Between the sessions, the model is situated in the external data base. However, the network's phantoms can be easily transformed into the standard threedimensional AutoCAD's networks (objects of the 3DFACE type). Means of the system's analysis work not only with the phantom models of networks. Using functions (construction of contour lines, profiles, intersections, the calculation of volumes, etc.) can be processed networks from AutoCAD objects (3DFACE and POLYMESH).
The basic stages of the model's life cycle are:
1. the initial generation
2. the editing
3. the analysis
Initial generation can be realized:
° by direct transformation from AutoCAD's objects (3DFACE and POLYMESH) with the retention of the elements topology
° by reading from ASCII  file, which contains description of the nodes and the values of the parameters, and the network's topological description
° by automatic generation of model using the massif of the irregular marks (pickets), which have an arbitrary quantity of parameters
Marks (pickets) for the model's generation can be obtained using different sources:
° drilling catalog (there is special program module for conducting and analysis of the drilling catalog)
° profiles catalog (special program module)
° digitalization of the structural lines with different parameters
° the digitalization of the contour lines with different parameters
° interactive node's insert
° field measurement's data(and electronic devices)
After initial generation, the model can be edited, using the following basic operations:
° node's displacement
° node's removal
° node's adding and/or correction
° addition of the marks with the separate parameters
° triangles's removal
° triangles's constructionin realtime
° flip (change) the diagonals of the triangles pairs of network
° input the bounding and preventing outlines
° input the contour lines with different parameters
° input the structural lines with different parameters
° substitution network's fragment by another network
° several networks association in a united model, etc
The generated and edited model can be saved to the external data base, and then, when it's necessary, loaded into the working storage during a session with any AutoCAD file and subjected to various kinds of the analysis:
° contour lines calculation and construction with different parameters
° value estimation at the arbitrary point
° the AutoCAD networks construction using the assigned parameter with the possibility of the color indication of a this parameter
° the volumes calculation of the contured networks and between two networks
° distances calculation along the arbitrary trajectories using the threedimensional geometry of the surfaces
° area calculation into the arbitrary outlines using the threedimensional geometry of the surfaces
° calculation and construction of the networks intersections in threedimensional space
° calculation and construction of sections along the arbitrary trajectories
° calculation and construction of the projection profiles of the linear objects
° calculation and construction of the projections of arbitrary curves on the network
° calculation and construction of the network's inclines
° calculation and construction of the Voronoj regions
° mathematical operations using networks
° creation and conducting of type catalog (type  content assigned relationship of the mineral's components and their properties)
° the calculation of obtained mineral into the arbitrary outline with the laying out on the types
The AutoCAD network's direct transformation functions into the Fata Morgana's model and vice versa, provide the possibility of using the models, created by users in AutoCAD and its applications, and exported into AutoCAD from other systems. And Fata Morgana's models can be exported into other systems using AutoCAD export mechanism.
The system is supplied with the specialized module for guaranteeing the possibility of preparation and analysis of geological data, which makes it possible to conduct the catalog of drilling holes and to produce some forms of analysis. For example: the automatic construction of the planned projections of drilling using indicated layer, or the drilling lithographic columns construction in the assigned ranges of marks and using different variants of tyings, the drilling threedimensional trajectories construction.
