This work studies large volume visualization when bricking techniques and 3d texture approaches are combined. The information got for the medical devices is bigger every day and we find problems at the moment of trying to visualize them interactively. Sometimes, volume required memory exceeds gpu capacity and that prevents its visualization. Among the different techniques of volume visualization and specially large volume treatment, we have chosen to implement 3D textures and bricking to evaluate their performance in terms of visual quality and speed of the combination of both techniques. 3D textures are chosen because they take most advantage from GPU than anyother technique, and bricking is chosen because its visualizations is identical to original volumen visualization if it would fit in memory. Provided that we work with medical information we want the visualizations will be exact. We have got encouraging results and they invite us to continuing working.
