Open Inventor extends Petrosys, SeisWare to 3D

VSG’s OpenGL extension offers software developers a short cut to 3D visualization.

New ‘customer spotlight’ white papers from Visualization Sciences Group (formerly TGS/Mercury) shows how Petrosys and SeisWare have leveraged VSG’s Open Inventor (OI) graphics library to extend their software to 3D. Open Inventor is an object-oriented, cross-platform 3D graphics toolkit for the development of interactive applications using C++, .NET or Java. OI comes as an application programming interface (API) for rapid prototyping and development of 3D graphics applications. OI extends the OpenGL graphics standard with a library of components for visualization and GPU-based rendering.

Petrosys’ new 3d-viz application extends its geoscience mapping package to 3D and supports a complex collection of surfaces and industry-specific objects. 3d-viz offers horizontal and vertical clipping planes, multiple light sources, a raster hard copy, movie making facilities and full interactive controls from Windows or Linux desktops.

The latest 7.0 release of SeisWare’s eponymous seismic interpretation suite introduced a 3D Seismic Visualizer. SeisWare leveraged its knowledge of OI’s C# interface in the development. The new 8.1 OI release offers a display rate ‘close to graphics hardware peak performance.’ A dynamic resolution mechanism applies rendering progressively, refining image quality on the fly. The new release is optimized for Nvidia QuadroPlex systems. More from
