public class Icosphere extends com.jme3.scene.Mesh
A 3-D, static, Triangles-mode mesh (with indices, normals, and texture coordinates) that approximates a sphere, generated by subdividing the faces of a regular icosahedron. The resulting mesh is more isotropic than a U-V sphere.

The texture coordinates are similar to Sphere.TextureMode.Projected, only with the U values mirrored and offset. Also, there is a boundary issue with the texture coordinates; this issue is very noticeable when the number of refinement steps is <3.

    • Icosphere

      public Icosphere(int numRefineSteps, float radius)
      Instantiate an icosphere with the specified radius and number of refinement steps:
      • 0 steps → 12 vertices, 30 edges, 20 triangular faces
      • 1 step → 42 vertices, 120 edges, 80 triangular faces
      • 2 steps → 162 vertices, 480 edges, 320 triangular faces
      • etcetera
      The center is at (0,0,0). All triangles face outward.
      Parameters:
      numRefineSteps - the desired number of refinement steps (≥0)
      radius - the desired radius (in mesh units, >0)
