As a result you get a "vector" $\vec{\Lambda}$, which components are barycentric coordinates of the point $\vec{x}$. To read more on the theory everything relies on, you may want to check " …

2023年3月30日 · I am trying to calculate the barycentric weights of a triangle from which I have no Cartesian coordinates- only a set of edge lengths describing the configuration of a flattened …

2023年3月8日 · I have a quadrilateral formed by the points A, B, C, D. I want to get the barycentric coordinates u, v, w, x so that: Au + Bv + Cw + Dx = [0, 0] How do I find the ...

Wikipedia's "Altitude (triangle)" entry describes the barycentric coordinates of $\triangle ABC$ 's orthocenter as $$(\tan A : \tan B : \tan C)$$ How would you prove this using solely the areal …

2020年12月2日 · This is because barycentric coordinates are not orthonormal. Therefore, I would recommend describing each line in the barycentric coordinates using two points. (This means …

2018年1月16日 · The word barycentric literally means “weight-centered.” The barycentric coordinates of a point relative to a polygon are the masses that you’d have to place at the …

This tag is for questions relating to Barycentric coordinate systems which describe the place of certain points in a triangle. They do not use distances of points, but only ratios of segments. …

2019年2月25日 · A concrete example that can help to understand a certain correspondence for a same affine transform presented either with affine coordinates or barycentric coordinates [I …

2014年4月19日 · The barycentric coordinates of the corners of any triangle are always $$[1:0:0] \qquad [0:1:0] \qquad [0:0:1]$$ So there is no angle information available. It tells you nothing …

2019年1月3日 · Without loss of generality, let $\,ABC\,$ be the three basis vectors in a cartesian coordinate system and let $\,O\,$ be the origin.
