Accelerating ray shooting through aggressive 5D visibility preprocessing [PDF]

Proceedings of the 2nd international conference on Computer graphics, virtual Reality, visualisation and interaction in Africa - AFRIGRAPH '03, 2003
We present a new approach to accelerating general ray shooting. Our technique uses a five-dimensional ray space partition and is based on the classic ray-classification algorithm. Where the original algorithm evaluates intersection candidates at run-time, our solution evaluates them as a preprocess.The offline nature of our solution allows for an ...

DC-Link Quasi-Switched Boost Inverter With Improved PWM Strategy and its Comparative Evaluation

IEEE Access, 2020
Low voltage stress on the impedance source network devices is the main reason for the advent of DC-linked type quasi-switched boost inverters (DqSBIs). However, the DqSBI has become less attractive due to its low voltage gain. This paper presents a novel

Buck Inverter without Shoot through

IET Power Electronics, 2017
A new buck inverter without shoot‐through problem is presented and analysed in this study. The traditional dual‐buck inverter has been proposed to solve the shoot‐through problem of bridge‐type inverters, eliminate the dead‐time effect and improve the reliability along with the conversion efficiency. However, the existing dual‐buck inverter is prone to
