Abstract�� Three dimension visualization of geology constructed model is used to display the exploration data in graphics methods directly, which is an important means to learn the geo body structure better, and provides useful proof for oil simulation. Based on the triangulation and interpolation algorithm, the geology layer and fault triangular grid models are constructed. Then four geology constructed model visualization methods, geology layer visualization, geology body visualization, geology profile visualization and dynamical geology visualization, are analyzed. The three dimension geology body is constructed by closing surfaces including boundary, faults and top layer. The geology boundary is triangular grids constructed by seaming layers adjacent; the fault surfaces are also triangular grids constructed by seaming fault lines adjacent. Three vital algorithms are implemented, which are the nearest neighbor first piecewise triangular reconstruction, triangular grid surfaces outer polygon boundary tracing and interaction line tracing between triangular grid surfaces and plane. In the end, visualization of various geology constructed model is given.
