    • A virtual reality presentation apparatus (100) has a CPU (101) which controls the overall apparatus, a memory (103) which stores various programs, a memory (104) which stores various data, an HMD (105) as a video display device, and a position and orientation controller (106) having position and orientation sensors (107, 108, 109), which are connected to each other via a bus (102). After a position and orientation required to render a CG scene for one frame are determined, when CG objects are in an interference state immediately before this processing and the difference between the current time and an interference time (128) set upon determining the interference state does not exceed an interference detection skip time (124), CG image generation means (112) generates a CG scene for one frame based on the determined position and orientation without checking if an interference has occurred between the CG objects.
    • 虚拟现实呈现装置(100)具有控制整个装置的CPU(101),存储各种程序的存储器(103),存储各种数据的存储器(104),HMD(105)作为视频显示装置 ,以及具有经由总线(102)彼此连接的位置和方位传感器(107,108,109)的位置和方位控制器(106)。 在确定用于渲染一帧的CG场景所需的位置和取向之后,当CG对象在该处理之前处于干扰状态以及当前时间与确定干扰状态之后设置的干扰时间(128)之间的差异 不超过干扰检测跳过时间(124),CG图像生成装置(112)基于所确定的位置和取向生成一帧的CG场景,而不检查CG对象之间是否发生干扰。
