摘要：
In this paper we focus on one particular set of free-form objects and its visualization. We extended approach for modeling curves and surfaces and prepared trivariate volumes based on Bezier and B-spline expressions. Our main goal is to visualize given parametric volumes. The visualization is done by approximation of volumes by net of isoparametric curves or surfaces and by boundary evaluation of volumes. Rendering is driven by OpenGL platform and there are used several techniques for enhanced visual effects like transparency. We also present practical output based on our implementation of proposed solutions.
