1. Visualização volumétrica aplicada às Geociências
This paper is on volume visualization of spatial data. It aims at showing new possibilities to visualize three-dimensional phenomena such as geology, soils, geophysics, seismic and the like. The use of volumes in the evaluation processes allows one to visualize and to explore the phenomenon as a continuous body in space, thus incorporating the third dimensio

2. USING POINT BASED TECHNIQUES FOR SEISMIC HORIZONS VISUALIZATION / USO DE TÉCNICAS BASEADAS EM PONTOS PARA VISUALIZAÇÃO DE HORIZONTES SÍSMICOS
Seismic horizon visualization stands as an important knowledge area used to support exploration on the oil industry. Different techniques currently employed to render this kind of surfaces are usually based on polygonal meshes generation, which benefits from graphics boards optimization on drawing triangles. This work is an evaluation of Point Based renderin

3. FAULT MESHING GENERATION IN SEISMIC DATA BY COMPETITIVE LEARNING / GERAÇÃO DE MALHAS DE FALHAS EM DADOS SÍSMICOS POR APRENDIZADO COMPETITIVO
Manual fault mapping from 3D seismic data is a time-consuming task. A plethora of seismic attributes has been proposed to enhance the discontinuity measures associated with faults. However, faults viewed through these attributes appear more like trends than well-defined, continuous surfaces, posing obstacles to the automation of the fault modeling process. T

4. 3D OPACITY IN VOLUME RENDERING OF SEISMIC DATA / OPACIDADE 3D NA VISUALIZAÇÃO VOLUMÉTRICA DE DADOS SÍSMICOS
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 opacit

5. VISUALIZAÇÃO VOLUMÉTRICA DE HORIZONTES EM DADOS SÍSMICOS 3D / VOLUME VISUALIZATION OF HORIZONS IN 3-D SEISMIC DATA
This work presents aspects of volume visualization of seismic horizons in 3-D seismic data. We consider both the direct and indirect approaches of volume visualization. In the direct approach we investigate the problem of selecting horizons using transfer functions. We present the 2-D opacity technique, which seeks to increase the ability to select horizons

6. AGRUPAMENTO E VISUALIZAÇÃO DE DADOS SÍSMICOS ATRAVÉS DE QUANTIZAÇÃO VETORIAL / CLUSTERING AND VISUALIZATION OF SEISMIC DATA USING VECTOR QUANTIZATION
This thesis suggests the use of a new method of seismic data clustering that can aid in the visualization of seismic maps. Seismic data are primarily made of signal and noise and, due to its dual composition, have asymmetric distributions. Seismic data are traditionally classified by methods that lead the proposed groups` references to their mean values. The

7. LabSis : um ambiente para desenvovimento de aplicações sismicas Matlab
The Matlab package is a tool of widespread use in the academic environment, because of its advantages in simple direct programming, graphs and visualization tools. It allows initial implementations of algorithms and procedures very quickly in a series of applications. As a counterpar to the above good qualities, Matlab programs do not exhibit the computation

8. ASPECTOS DE LA VISUALIZACIÓN VOLUMÉTRICA DE DATOS SÍSMICOS / ASPECTS ON VOLUME RENDERING OF SEISMIC DATA / ASPECTOS DA VISUALIZAÇÃO VOLUMÉTRICA DE DADOS SÍSMICOS
A visualização volumétrica direta (volume rendering) aplicada a dados sísmicos é uma técnica ainda emergente. Apenas recentemente alguns software comerciais tornaram-se disponíveis para a indústria de petróleo. Comparado ao método tradicional de interpretação sobre seções bidimensionais, essa técnica representa uma alternativa interessante que
