Based on forming irregular triangular network, the authors adopted surface spline as interpolation algorithms, and then used Open GL to light, successfully realized the modeling of bedded mineral deposit, making it be able to rotate in a certain angle and direction.

The coefficients of lift and pitch moment of experimental aerodynamic forces were introduced into the longitudinal maneuvering flight computation by use of surface spline,and flight loads on overall aircraft were elastically corrected based on pressure distribution of experimental aerodynamic forces simultaneously.

Based on B-net subdivision technique, a new algorithm on displaying bivariate spline surface, defined on triagular domain with three direction mesh,is discussed.

The paper introduces an algorithm for creating smooth spline surfaces over control triangular meshes capable of outlining arbitrary free-form surfaces with or without boundary.

The spline surface and the original surface are combined to generate a new rational surface by adding the weights.

Using triangular basis function,although T-B spline curve presents convexity-preserving property,but it couldn’t interpolate through any given control points.

Improvement on modeling a 3-D yarn with B-spline surface;

Study on constructing the 3D yarn model by B-spline surface (part Ⅱ):inserting 3D bumping texture on the surface of the yarn;

Interpolation for improving the subpixel spatial resolution based on bi-cubic B-spline surface;

A new method of rapid evaluation of B-spline surfaces was proposed with GPU fragment program.

At the same time, we need to transform triangular mesh model to parameterized smooth B-Spline surfaces in order to redesign the part or other consequent application.
