In holography, the resolution of the hologram significantly impacts both display size and angle-of-view, yet achieving high-resolution holograms presents formidable challenges, whether in capturing real-world holograms or in the computational demands

We propose a novel graphics processing unit (GPU) algorithm that can handle a large-scale 3D fast Fourier transform (i.e., 3D-FFT) problem whose data size is larger than the GPU's memory. A 1D FFT-based 3D-FFT computational approach is used to solve

The lens distortion process is essential for displaying VR contents on a head-mounted display (HMD) with a distorted display surface. This paper proposes a novel lens distortion algorithm to achieve real-time performance on edge devices with an embed

Fast Fourier Transform (FFT) is a fundamental operation for 2D data in various applications. To accelerate large-scale 2D-FFT computation, we propose a Heterogeneous parallel In-place 2D-FFT algorithm, HI-FFT. Our novel work decomposition method make

We present a novel GPU‐based ray‐casting algorithm for volume rendering of unstructured grid data. Our volume rendering system uses a ray‐casting method that guarantees accurate rendering results. We also employ the per‐pixel intersection lis
