Ultra-Fast Image Reconstruction of Tomosynthesis Mammography Using GPU

Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...

Optimized View Frustum Culling Algorithms for Bounding Boxes

This paper presents optimizations for faster view frustum culling (VFC) for axis aligned bounding box (AABB) and oriented bounding box (OBB) hierarchies. We exploit frame-to-frame coherency by caching and by comparing against previous distances and rotation angles. By using an octant test, we potentially halve the number of plane tests needed, and we also evaluate masking, which is a well-known...

Computing a View Frustum to Maximize an Object's Image Area

This paper presents a method to compute a view frustum for a 3D object viewed from a given viewpoint, such that the object is completely enclosed in the frustum and the object’s image area is also near-maximal in the given 2D rectangular viewing region. This optimization can be used to improve the resolution of shadow maps and texture maps for projective texture mapping. Instead of doing the op...

Fast Rendering of Large Crowds Using GPU

This paper proposes a fast rendering algorithm for real-time animation of large crowds, which is essential for video games with a large number of non-player characters. The proposed approach leaves the minimal work of rendering to CPU, and makes GPU take all the major work, including LOD assignment and view frustum culling, which have been the typical tasks of CPU. By offloading the rendering o...

Practical Shadow Mapping

In this paper we propose several methods that can greatly improve image quality when using the shadow mapping algorithm. Shadow artifacts introduced by shadow mapping are mainly due to low resolution shadow maps and/or the limited numerical precision used when performing the shadow test. These problems especially arise when the light source’s viewing frustum, from which the shadow map is genera...
