3d

问题 I want to make a 3D representation of a large number of spheres of different diameter using gnuplot and whose information are in a file called 'data.dat' . If I do: splot 'data.dat' u 1:2:3 w p lt 7 I get a series of points of small dimensions of a homogeneous color. How can I add the real size of the spheres (read from the 4th column of the file 'data.dat' ) using the splot command? Something like: splot 'data.dat' u 1:2:3:4 ... 回答1: Since gnuplot 5.4, I guess you have the plotting style

问题 I just cant get access to the babylon mesh. Everytime I try to run the code I get this error. I've tried it with two different approaches: Example 1: var carTest; BABYLON.SceneLoader.ImportMesh("", "assets/", "car.obj", scene, function(object) { carTest = object[0]; }); carTest.position.x = 10; Example 2: var carTest = BABYLON.SceneLoader.ImportMesh("", "assets/", "car.obj", scene); carTest.position.x = 10; 回答1: In your example 2, The BABYLON.SceneLoader.ImportMesh return Nullable

问题 i have two point each point has its own X and Y value and they have the same Z value. i want a function to draw Cylinder between these two points. 回答1: For building a cylinder with two given points, you need vector analysis. You are building two perpendicular vectors which are added to each point and scaled with sin/cos multiplied with the radius. It accepts all points (The old code had a bug because it missed the sqrt() for the length). Now it functions correctly and draw the cylinder with
