just a guess, you could probably use the formula for a sphere centered at (0,0,0) x²+y²+z²=1 solve this for x, then loop throuh a set of values for y and z and plot them with your calculated x.

Dec 24, 2018 · I'm making a game and I need a way to generate a sphere mesh in Unity for whatever reason. It needs to be generated by code and not be a pre-made sphere or a sphere primitive as I need to edit in generation later on.

Aug 30, 2011 · Sphere using spherical coordinates walk. For the first way, you just use a double nested for to walk theta and phi. As you walk theta and phi, you spin triangles to create your sphere. The code that does it will look something like this:

Oct 4, 2018 · I'm trying to create a triangle mesh of a sphere surface and draw it with OpenGL 4.1. This is the code that I'm currently using obtained from the second answer of that question, The vertex layout is [x, y, z, r, b, g, a] that's why there is 7 float foreach vertex:

In Matplotlib, I want to draw a sphere with a mesh on its surface, divided into 30 degrees steps in spherical coordinates. The code: from mpl_toolkits.mplot3d import Axes3D import matplotlib.pypl...

Feb 17, 2021 · I'm trying to use gmsh 4.7.1 to create a mesh within a 3D volume, that is a sphere with a concentric spherical hole (in other words, I have a spherical shell). In order to do so, I wrote the following .geo file:

Oct 7, 2011 · The following pseudocode generates a triangle mesh by evaluating a parametric function at regular intervals (this works for any parametric surface function, not just spheres). In the pseudocode below, UResolution is the number of grid points along the U axis (here, lines of longitude), and VResolution is the number of grid points along the V ...

Aug 11, 2014 · I'm trying to interpolate and visualize a function on the surface of a sphere. For this, I need a meshgrid with the coordinates of interpolation points on the sphere. Initially, I tried to generate my sphere using . phi, theta = np.mgrid[0:pi:n, 0:2 * pi:n] …

\$\begingroup\$ I made the mesh in Blender; I literally just took a sphere and cut out half the vertices, then threw it into Unity. I don't recall doing anything about the UV layout. And I applied the material to the whole mesh, which is half a sphere. (I'm trying to use half a sphere as a performance optimization.) \$\endgroup\$ –

Jun 6, 2018 · The minimum enclosing sphere problem can be solved with an average algorithmic complexity of O(n 4) for a naive algorithm working on free vertices, down to an easy O(nk) where k is the number of vertices of the equivalent convex hull of your starting mesh.
