Technologies in three-dimensional visualization for real-time fusion of multiple seismic attribute volumes

The technology of multi-attribute fusion is a new technology developed in recent years for the limitation of single attribute. Through the research of real-time fusion of multiple seismic attribute volumes in three-dimensional space, an implementation scheme is proposed. In order to realize the three-dimensional visualization for fusion of multiple attribute volumes, the scheme uses octree structure to manage data effectivly and dynamically, and makes full use of programmable pipeline of GPU to accelerate based on Shader programming technology. A 3D visualization system for multi-attribute volumes fusion is developed based on this scheme, which realizes two kinds of fusion technology based on RGB mapping and attribute weighting, ensuring high quality and real-time rendering of multi-attribute volumes fusion, which is proved to be very effective in practice.
