This paper describes an object-order real-time volume rendering architecture using an adaptive resampling scheme to perform resampling operations in a unified parallel-pipeline manner for both parallel and perspective projections. Unlike parallel projections, perspective projections require a variable resampling structure due to diverging perspective rays. In order to address this issue, we propose an adaptive pipelined convolution block for resampling operations using the level of resolutiondoi:10.1145/288126.288146 dblp:conf/vvs/OgataOLP98 fatcat:iersgylgbbayfpxqpdiojyje2a
