Collision detection is pretty important in Virtual Reality, and its speed greatly influences the reality and illusion of immersion in virtual environment. We propose a collision detection algorithm of hybrid bounding box based on the merits of AABB and OBB: AABB-OBB. It is applicable to solid objects. We construct simpler bounding volume tree and apply(More)
OBJECTIVES The aim of this study was to investigate the cardioprotective effect of salvianolic acid B (Sal B) on acute myocardial infarction (AMI) in rats and its potential mechanisms. METHODS The AMI model was established in rats to study the effect of Sal B on AMI. Haematoxylin-eosin (HE) staining was used to evaluate the pathological change in AMI(More)
In this paper, an optimization algorithm is proposed based on the Oriented Bounding Box (OBB), due to comparatively large cost generated in the overlap test among OBBs (B-B). A simpler bounding box tree is established by researching the collision detection between the Bounding Box and primitive (B-P). It uses an improved tree structure to reduce storage(More)
This paper presents a hybrid automatic test pattern generation (ATPG) technique using the staggered launch-on capture (LOC) scheme followed by the one-hot LOC scheme for testing delay faults in a scan design containing asynchronous clock domains. Typically, the staggered scheme produces small test sets but needs long ATPG runtime, whereas the one-hot scheme(More)
