Orad brings new photorealism to virtual studios
Orad Hi-Tec Systems, a provider of 3-D real time graphic solutions announced the new version of its ProSet virtual studio system at NAB 2008 (booth #SU1920), which allows the insertion of semitransparent objects into the virtual studio.
The ProSet system allows the insertion of semitransparent 3-D graphical elements into the virtual studio by separating the alpha and graphics from the background, enabling complete multilayer compositing. As a result, ProSet enables the object in the foreground to have a separate alpha and graphics input from those in the background, providing full control over the transparency of the foreground object without affecting the other elements in the virtual studio.
The new version of ProSet is also equipped with a soft garbage matte feature. Often in virtual studio productions, the camera pans out of the blue or green box area; this off box area is typically masked using garbage matte. However the edges of the blue box are frequently visible on the composite image as visible lines, making the difference in brightness between the keyed area and garbage matte very visible. The soft garbage matte feature addresses this issue, providing a seamlessly soft and blended image.
