问题 given a 3D grid, a 3d point as sphere center and a radius, i'd like to quickly calculate all cells contained or intersected by the sphere. Currently i take the the (gridaligned) boundingbox of the sphere and calculate the two cells for the min anx max point of this boundingbox. then, for each cell between those two cells, i do a box-sphere intersection test. would be great if there was something more efficient thanks! 回答1: There's a version of the Bresenham algorithm for drawing circles.

问题 I created three overlapping plots in R using the diamonds data set using the viewports below. Is it possible to get them formatted the same way [overlapping] into a .pdf file? vp <- viewport() sbvp <- viewport(width=1,height=1,x=.5,y=.5) sbvp1 <- viewport(width=.4,height=.2,x=.28,y=.18) sbvp2 <- viewport(width=.4,height=.2,x=.8,y=.72) print(p0, vp=sbvp) print(p1, vp=sbvp1) print(p2, vp=sbvp2) Tried two separate ways [one below]. I understand ggsave wasn't working because it just works on the
