• With UV mapping, the checkers tile the two-dimensional UV space, and points on the sphere map to this space according to their latitude and longitude. UV unwrapping. When a model is created as a polygon mesh using a 3D modeller, UV coordinates (also known as texture coordinates) can be generated for each vertex in the mesh. One way is for the 3D modeller to unfold the triangle mesh at the seams, automatically laying out the triangles on a flat page.
  • The Subdivision Surface modifier demonstrates why good, clean topology is so important. As you can see in the figure, the it has a drastic effect on a default cube. Until you add in additional loops (with e.g. Loop Cut and Slide), the shape is almost unrecognizable as a cube.
  • I have my simulation output a csv text file of x,y,z,r for a few dozen such spheres so it would be very hard to create each one manually. I'm taking a Lynda.com course on Blender basics now, but I think this is probably a fairly advanced thing. For now, I just need a quick and dirty way to generate a figure for a deadline I have coming up.
Aug 22, 2015 · Using the CSS border-radius property, we can create rounded shapes and circles. Add some gradients and they become spheres. Let’s try that, and add some animation to bring them to life. Flat design. There are two ways we could approach making spheres with CSS. One is to create an actual 3D sphere using lots of elements.
Feb 16, 2015 · The sphere that doesn't get enough credit is the subdivided spherified cube. It's intuitive to generate naïvely, incredibly easy to UV unwrap unlike the icosphere, and it doesn't suffer awful pinching at the poles like the UV sphere. It gives an acceptable middle ground for uniformity of geometric density.
create UV sphere with low poly count (32/16) remove the top and bottom caps (select edge loop of vertices, delete vertices) for each hole, close it using fill grid (8 divisions) bump the grid vertices so they fit the overall round shape (initially they are flat).
Apr 16, 2014 · The sphere map contains everything that is in front of the camera, which means that the texture contains the incoming light inciding in the surface facing the camera. That’s why it doesn’t work as a perfect environment map: it doesn’t rotate with the view because it’s missing part of the information.

Jul 26, 2020 · The Basics of UV Mapping Add a sphere . We'll use a sphere for this demonstration. Delete the initial cube ( A ). Then, create a new model, a sphere ( Shift + A → Add → Mesh → UV Sphere). Leave the settings at default for now. Mark a UV seam
  • Jul 03, 2019 · You can export a visual representation of the UV map from your 3D modeling program to use as a guide in Photoshop if texturing that way. The exact method of exporting will depend on the modeling package you are using. Once you have the UV map guide in Photoshop, it's really just painting after that to create your texture maps.

  • Apr 29, 2018 · I’m trying to unwrap the default UV sphere to apply the following texture without stretching or overlapping. You can never have a UV texture for a curved surface without some stretching. Having said that, for a UV sphere, a straightforward way to minimise the stretching is to unwrap as gores (like an old-fashioned globe):

For many purposes it is perfectly fine, but for some use cases, e.g. if you want to deform the sphere, it is disadvantageous that the density of vertices is greater around the poles. Here the icosphere is better, its vertices are distributed evenly. Icospheres are a type of geodesic dome. So I want to create a icosphere programmatically.
