AI Technical Summary

Problems solved by technology

Rasterization technology is commonly used in real-time interactive rendering, but this technology does not support various complex indirect lighting effects
The difficulty of using ray tracing for real-time interactive rendering is that the calculation of ray tracing is too large to achieve real-time rendering speed

Embodiment Construction

[0027]In order to make the features and advantages of this method clearer, the system and method will be further described below in conjunction with specific embodiments. In this embodiment, consider a room three-dimensional scene, there is a flying saucer in mid-air in the room, there are tables, chairs and cabinets in the room, and the flying saucer geometric object is a three-dimensional geometric object that performs somatosensory interaction with participants in the somatosensory interaction; when participating When the somatosensory interaction person uses the right arm to make an attracting action, the flying saucer will fly to the position of the virtual camera, that is, to the person participating in the somatosensory interaction; when the somatosensory interaction person uses the left arm to make an arm movement, the flying saucer will fly away from the virtual camera Move in the direction of the location, that is, fly away from the person participating in the somatos...

Abstract

The invention discloses a somatosensory interactive rendering system and method for a realistic three-dimensional scene, which uses a parallel computing cluster composed of multiple GPU computing nodes, and uses GPU parallel ray tracing technology to realize the rendering of a realistic three-dimensional scene. Using different parallel granularities within a single GPU computing node and among multiple GPU computing nodes, the parallel capability of the GPU computing cluster is fully utilized. Use the Kinect somatosensory sensor to collect the depth of field data of the participating interactors, and extract the skeletal joint points of the participating interactors for somatosensory interaction control. The present invention can support the somatosensory interaction between a single participant interactor and a single geometric object in a three-dimensional scene, and realize the somatosensory interaction effect that the three-dimensional interactive geometric object comes and disappears as soon as it is called.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional graphics rendering, and relates to a somatosensory interactive rendering system and method for realistic three-dimensional scenes. Background technique [0002] 3D scene rendering can generally be divided into two types: offline rendering and real-time interactive rendering. In the production of film and television special effects, offline 3D scene rendering technology is usually used. The three-dimensional scenes drawn by this type of technology are very realistic, but the drawing time is generally very long. In 3D computer games, however, real-time interactive rendering techniques are used. At present, the speed of drawing three-dimensional scene pictures by using this kind of technology can meet the requirement of real-time interaction, but the realism of the pictures is often poor. Ray tracing is often used in offline 3D scene rendering, which can draw realistic 3D scene images. ...
