OPEN CASCADE Multiple Variable Function

摘要: Abstract. Multiple variable function with gradient and Hessian matrix is very very import in OPEN CASCADE optimization algorithms. In order to understand these optimization algorithm better, let’s study some basic knowledge about Gradient, Hessian Matrix.

OPEN CASCADE Gauss Least Square

摘要: Abstract. The least square can be used to solve a set of n linear equations of m unknowns(n >= m). The OPEN CASCADE class math_GaussLeastSquare implements the least square solution of the linear equations by using Gauss LU decomposition algorithm. The paper focus on the Least Square method to solve the linear equations.

OPEN CASCADE Curve Continuity

摘要: Abstract. 設(shè)計(jì)一條復(fù)雜曲線時(shí)，出于設(shè)計(jì)和制造上的考慮，常常通過(guò)多段曲線組合而成，這就需要解決曲線段之間如何實(shí)現(xiàn)光滑連接的問(wèn)題。評(píng)價(jià)曲線間連接的光滑度的度量有兩種：參數(shù)連接性和幾何連續(xù)性。本文對(duì)這兩種連續(xù)性分別進(jìn)行介紹。
