在增强现实中模拟“X射线视觉”时，一个关键方面是确保正确感知被遮挡物体的位置。在真实世界的遮挡物上对遮挡对象进行简单的覆盖渲染可能会导致对视觉场景的误解和对深度的不良感知。我们提出了一个简单的技术，以提高在场景中的空间安排的看法。与遮挡物相关联的重要性掩模通知渲染可以覆盖哪些信息以及应该保留哪些信息。这种技术是独立的场景属性，如照明和表面属性，这可能是未知的。所提出的解决方案是有效地计算在GPU上的单通道片段着色器。
When simulating "X-ray vision" in Augmented Reality, a critical aspect is ensuring correct perception of the occluded objects position. Naïve overlay rendering of occluded objects on top of real-world occluders can lead to a misunderstanding of the visual scene and a poor perception of the depth. We present a simple technique to enhance the perception of the spatial arrangements in the scene. An importance mask associated with occluders informs the rendering what information can be overlaid and what should be preserved. This technique is independent of scene properties such as illumination and surface properties, which may be unknown. The proposed solution is computed efficiently in a single-pass fragment shaders on the GPU.
