JT (Jupiter tessellation) is an efficient, industry-focused and flexible ISO-standardized 3D data format developed by Siemens PLM Software. Mechanical CAD domains of Aerospace, automotive industry, and Heavy Equipment use JT as their most leading 3D visualization format.
OBJ files are used by wavefront's advanced visualizer application to define and store the geometric objects. Backward and forward transmission of geometric data is made possible through OBJ files. Both polygonal geometry like points, lines, texture vertices, faces and free-form geometry (curves and surfaces) are supported by OBJ format. This format does not support animation or information related to light and position of scenes.
