3D Modelling of Chua's Circuit Boundary Surface

Integrative 3D modelling of complex carving surface

Modelling of a complex carving surface is the most important process for digitization of art carving such as Chinese classical furniture carving, and it is difficult to be fulfilled. However, a complex 2D curve flower pattern can be easily acquired or drawn by handcraft or a drawing software. This paper presents a quick integrative 3D modeling method of complex carving surface based on a 2D cur...

Computer Modelling of 3D Geological Surface

— The geological surveying presently uses methods and tools for the computer modeling of 3D-structures of the geographical subsurface and geotechnical characterization as well as the application of geoinformation systems for management and analysis of spatial data, and their cartographic presentation. The objectives of this paper are to present a 3D geological surface model of Latur district in...

Surface Detail Mapping in 3D Modelling

Automated 3D Geological Surface Modelling With CDT

Advances in computer technologies make it possible to create three-dimensional and interactive geological information systems. A Constrained Delaunay Triangulation (CDT) algorithm which considered the line segments of the geological polygons as constrained edges and all vertices of the digital elevation model (DEM) inside the polygons was applied to construct CDTs. Triangles outside the polygon...

Fundamentals of 3D modelling and resource estimation in coal mining

The prerequisite of maintaining an efficient and safe mining operation is the proper design of a mine by considering all aspects. The first step in a coal mine design is a realistic geometrical modelling of the coal seam(s). The structural features such as faults and folding must be reliably implemented in 3D seam models. Upon having a consistent seam model, the attributes such as calorific val...
