Try the Map function: Show[Graphics3D[{RGBColor[1,0,0], PointSize[0.04], Map[Point[#] &, position]}]]; John C. Erb email: John_C_Erb at prodigy.net -----Original Message----- From: Jong Choi [mailto:jxc91 at po.cwru.edu] To: mathgroup at smc.vnet.net Subject: [mg41823] [mg41781] For[] command in Show[] function Dear All, I want to show the 18 points in the 3D space. So I used the Show[ ] function. But in every points, I should type the Point[position[i]] repeatly. If I can use the For[ ] routine, the code will be simple. Please let me know how to use For routine in the Show[ ] function or how to show a lot of points in 3D space with simple codes. Thanks, Jong Code : position = { {-10, -13, 0}, {-12, -13, 0}, {-14, -13, 0}, {-16, -13, 0}, {-10, -13, -2}, {-12, -13, -2}, {-14, -13, -2}, {-16, -13, -2}, {-10, -13, -4}, {-12, -13, -4}, {-14, -13, -4}, {-16, -13, -4}, {-10, -13, -6}, {-12, -13, -6}, {-14, -13, -6}, {-16, -13, -6}, {-10, -13, -8}, {-12, -13, -8}}; Show[Graphics3D[ {RGBColor[1, 0, 0], PointSize[0.04], Point[position[[1]]], Point[position[[2]]], Point[position[[3]]] , Point[position[[4]]], Point[position[[5]]], Point[position[[6]]] , Point[position[[7]]], Point[position[[8]]], Point[position[[9]]] , Point[position[[10]]], Point[position[[11]]], Point[position[[12]]] , Point[position[[13]]], Point[position[[14]]], Point[position[[15]]] , Point[position[[16]]], Point[position[[17]]], Point[position[[18]]] }] ] Expected code : (not correct) Show[Graphics3D[For[i=1,i<19,Point[ position[[i]] ],i++]]]; ================================ Jongung Choi Biologically Inspired Robotics Laboratory Mechanical and Aerospace Engineering Case Western Reserve Univ.
