【Abstract】 In accordance with characteristics of 3D finite element irregular data field, a direct volume rendering algorithm that is based on scan\|buffer and particularly suitable to multiple types of finite elements is proposed. The influence of functions mapping data field to density field on the image result is discussed, and several mapping models available to finite element data field are proposed.更多还原
