Umbra is a cross-platform subprogram that integrates with other software products, optimizing and thus increasing the frame rate and increasing the efficiency and speed of the content pipeline. [2]
Umbra supports personal computers and game consoles PlayStation 3 and Xbox 360 . [one]
In the process, Umbra determines the set of visible and invisible objects in each frame, determining which objects are visible and which are not from the point of view of the camera. If invisible objects and surfaces do not go through the rendering stage, system performance increases. Umbra eliminates all invisible graphical objects from the processing, thereby increasing productivity. [2] [4]
A trial version of Umbra is available. [1] To use Umbra, you must have a graphics card with a GPU of at least Direct3D 9 and / or OpenGL 1.5. [one]
