Stereoscopic visualization for model of deformation of steels with mushy zone
Languages of publication
The paper deals with visualization of results for simulation of a deformation process of a sample with a mushy zone. The numerical model consists of three basic subsystems: the mechanical, thermal and density changes parts. These describe both solid and semisolid deformation states. Taking into consideration their specific distribution graphical visualization is very helpful for understanding the course of the process. Moreover, a three-dimensional presentation is applied in various fields, ranging from medical imaging systems to technological processes assistance to scientific visualizations and entertainment. The stereoscopic imaging technique is still being developed. It is based on the idea of showing each eye the same scene from a bit different perspective. As an effect the illusion of depth is created due to the way the two images are interpreted by the human brain. Stereoscopy is not a new concept, but in the past few years a significant increase in the interest in this method of visualization could be observed. It is caused by computer and audio-visual technology development. In the paper several techniques of creating stereoscopic images are presented together with their physical bases and devices providing such functionality. The use of projection equipment and possibilities of its application to visualization of semi-solid steel deformation is discussed. Apart from that a description of an implementation of OpenGL specification for stereoscopic presentation of computer simulation results is provided.
