Mobile phones offer an excellent low-cost alternative for Virtual Reality. However, the hardware constraints of these devices restrict the displayable visual complexity of graphics. Image-based rendering techniques arise as an alternative to solve this problem, but usually, the support of collisions and irregular surfaces (i.e., any surface that is not flat or even) represents a challenge. In this work, we present a technique suitable for both virtual and real-world environments that handle collisions and irregular surfaces for an image-based rendering technique in low-cost virtual reality. We also conducted a user evaluation for finding the distance between images that presents a realistic and natural experience by maximizing the perceived virtual presence and minimizing the cybersickness effects. The results prove the benefits of our technique for both virtual and real-world environments.

具有碰撞和不规则表面的低成本虚拟现实中的高视觉质量场景

移动电话为虚拟现实提供了极好的低成本替代方案。然而，这些设备的硬件限制限制了图形可显示的视觉复杂性。基于图像的渲染技术作为解决此问题的替代方案而出现，但通常，碰撞和不规则表面（即任何不平坦或不平坦的表面）的支持是一个挑战。在这项工作中，我们提出了一种适用于虚拟和现实世界环境的技术，用于处理低成本虚拟现实中基于图像的渲染技术的碰撞和不规则表面。我们还进行了一次用户评估，以通过最大化感知的虚拟存在和最小化网络病效应来寻找呈现逼真和自然体验的图像之间的距离。
