在3D polygon Triagulate (之二)这一篇里前几步里有很有意思的操作: ... Project the points to the plane. Transform the points into the coordinate system of the plane, so that every point has a 2D coordinate (x, y) and a depth z ... 这里就来看一下 Project the points to plane 这个操...

A branch point was classified as a node with two or more offspring nodes, with the branch number equating to the total of these points. Each neuron possessed multiple terminals projecting onto the cortex. The length from the neuronal soma to each cortical terminal was defined as an axonal ...

Finally, we have a way to transform some arbitrary 2D point (a, b) on the image to a 3D point on the virtual screen.That formula inspired these additions to Vec:// p = o + p[0] u + p[1] v public static void map( double[] p, double[] o, double[] u, double[] v) { ...
The generation of knit patterns of the MeiTing project uses a combinatory approach. For the main body of the fabric, the approach with a flattening process is used. It first flattens the 3D design model onto the XY plane and then “relaxes” the flattened model to maintain an equal length...
