RESUMO

This work proposes a 3D opacity technique for the volume rendering of seismic data. The greater challenge of volume rendering is to define a multidimensional transfer function better adapted to the data to be visualized. This work presents a transfer function that uses three 1D color tables to compose a 3D color table. The work from Silva[30] about 2D opacity has served as a motivation for the development of the 3D opacity technique and, hence, some comparisons are made between them. Some examples are presented in order to reproduce the 2D opacity technique and to show how the proposed technique can improve the visualization of specific seismic events.
