Patchwork3D visualization software from Lumiscaphe allows operations to be executed in real time, with results seen in 3-D and real time on the designer’s screen. This enables the designer to work faster and to review and present projects smoothly. High-quality rendering also provides accurate visualization when walking through a scene in 3-D, even for complex scenes loaded with texture. The software enables engineers to produce work free of errors, thus reducing time to market. It eliminates the need for physical mockups used for project reviews. It also permits companies to test new materials quickly and determine whether they will perform properly on complex surfaces. An unwrapping module allows the flattening, in 2-D, of complex 3-D surfaces to assist proper material cutting for application on 3-D surfaces and optimize the use of material.
