With ever-increasing display resolution for wide field-of-view displays—such as head-mounted displays or 8k projectors—shading has become the major computational cost in rasterization. To reduce effort, we propose an algorithm that only shades visible features of image while cost-effectively interpolating remaining without affecting perceived quality. In contrast to previous approaches do not simulate acuity falloff but also introduce a sampling scheme incorporates multiple aspects human...

Advances in computer graphics enable us to create digital images of astonishing complexity and realism. However, processing resources are still a limiting factor. Hence, many costly but desirable aspects realism often not accounted for, including global illumination, accurate depth field motion blur, spectral effects, etc. especially real-time rendering. At the same time, there is strong trend towards more pixels per display due larger displays, higher pixel densities or fields view. Further...

Immersion is the ultimate goal of head-mounted displays (HMD) for Virtual Reality (VR) in order to produce a convincing user experience. Two important aspects this context are motion sickness, often due imprecise calibration, and integration reliable eye tracking. We propose an affordable hard- software solution drift-free eye-tracking user-friendly lens calibration within HMD. The use dichroic mirrors leads lean design that provides full field-of-view (FOV) while using commodity cameras Our...

Abstract Ray‐axis aligned bounding box intersection tests play a crucial role in the runtime performance of many rendering applications, driven not by complexity but mainly volume required. While existing solutions were believed to be pretty much optimal terms on current hardware, our paper introduces new test requiring fewer arithmetic operations compared all previous methods. By transforming ray we eliminate need for one third traditional bounding‐slab and achieve speed enhancement...

Virtual reality has ushered in a revolutionary era of immersive content perception. However, persistent challenge dynamic environments is the occurrence cybersickness arising from conflict between visual and vestibular cues.
