| In this thesis some methods for visualizing three dimensional seismic data are presented.; The notion of bricks of seismic data sets is employed since the seismic data sets are usually very large. Bricks are rectangular subsets of a seismic datasets which can be stored in the memory of a standard PC.; Texture mapping is used to surface render 2D slices. By sweeping a slice plane through a data volume the data can be visualized in a 3D manner.; An automatic horizon tracking approach is developed using an amplitude based horizon tracking algorithm, and it is applied to field seismic datasets. The algorithm is similar to the mesh propagation algorithm developed in isosurface extraction techniques.; The software system is developed using OpenGL API and Qt GUI. OpenGL applications enjoy broad platform accessibility in the industry, and Qt provides a platform-independent API to all central platform functionality, e.g., GUI and file handling. The combination of OpenGL and Qt is the premier environment for developing portable, interactive 2D and 3D graphics application, which is ideal for seismic data visualization and interactive realtime interpretation. The design of the software is described in detail. |
