Abstract:
A haptics rendering system comprises: a display device having a display screen and one or more haptic feedback mechanisms associated with at least one tactile output peripheral; and a graphics processing unit (GPU) communicatively coupled to the display device. The GPU: receives one or more portions of display image software code for a three dimensional display image; generates a three dimensional (3D) visual output of the display image for display on the display device; and concurrently generates one or more specific friction maps to provide haptic feedback of depth and/or texture associated with specific portions of the display image that comprise at least one portion having at least one of a different depth and a different texture than other portions of the display image. The GPU renders the display image and the friction map from a same set of 3D commands within the display image software code.
