In performing regularized set. operations on two solids, the most difficult step is boundary classification, in which the boundaries of each solid are split into portions that are inside, outside, or on the surface of the other solid. In this paper, we present a method for doing boundary classification on polyhedral solids and give measurements of the algorithm's time complexity on a number of ...

This paper presents a scan curve algorithm for evaluating the face area of solids in constructive solid geometry (CSG) representation. Compared to previous methods, the algorithm is more accurate and computationally faster. The applicable domain is limited to solids bounded by three classes of surfaces: all quadric surfaces, cylindrical surfaces, and surfaces of revolution which are algebraic s...

Glucose yield from the enzymatic hydrolysis of cellulose was investigated as a function of cellulase enzyme loading (7-36 FPU/g cellulose) and solids concentration (7%-18% total solids) for up to 72 h on dilute sulfuric-acid pretreated Douglas Fir. The saccharification was performed on whole hydrolysate with no separation or washing of the solids. Enzyme loading had a significant effect on gluc...
