The idea behind this paper is to focus the review on visualization techniques for medical data and its applications of information visualization and scientific visualization methods for any types of real-time data. Many works related to the field of computer graphics, and computer visualizations are presents. The paper deals, how to improve the quality in the images or objects, removing the noises from images, and graphically represent any graphical inputs. The main goal of our review work is to show few efficient rendering techniques for medical images and geometric primitives. Finally, this review work provides to further development of higher-dimensional data into the field of computer visualization techniques. © 2010 RJPBCS.
