这对拟合FEX提交提供了一套工具2D conics (ellipses, circles, lines,...) as well as 3D quadric surfaces (ellipsoids, spheres, planes, cylinders, cones,...). Each type of fit is represented by an object within a class hierarchy. For each fit type, overloaded methods are provided for generating noisy test data, fitting the data, and visualizing and post-sampling the results.

Currently, not all curve/surface types in the conic/quadric family are covered by this tool set, although I may add more over time. For now, I provide a subset of the ones that seem to be the most commonly encountered. Similarly, most fitting algorithms used by the tool set are very basic algebraic methods, although I may add more refined algorithms as the need and interest arise.

Various example uses of these tools are illustrated in the Examples tab.

バージョン	公開済み	リリースノート
1.2.8	2022/10/25	Added some functionality to planarFit.project2D and planarFIt.unproject3D(). Embellished example in "Fitting a 2D Shape to 3D Points", making it a 3D ellipse fit.	ダウンロード
1.2.7	2022/10/25	Minor edits to Examples.mlx	ダウンロード
1.2.6	2022/10/25	Added some tools and examples to help with fitting circles, ellipses, and other 2D shapes that are sampled in 3D. See the Examples.mlx section "Fitting a 2D Shape to 3D Points".	ダウンロード
1.2.5	2021/6/24	Bug fix in circularFit.sample().	ダウンロード
1.2.4	2021/6/18	Cosmetic update: default axis labels will now be provided on all plots.	ダウンロード
