Pre-Normalized cube model?
I need a normalized cube model/prefab that has been pre-generated, rather than normalized in code.
Edit: If people could stop telling me about Unity's primitive cubes, that would be great. :P This is a cube that has had it's vertices normalized, as is what I'm looking for:
Anyone know where I can find one?
What about the basic prefab cube?
If not, make one in Blender.
tbh all I see is a mesh. There is no indication of 'normalised' there. To me, normalised means that the face is set to be outwardly perpendicular. There are no faces on that cube. $$anonymous$$aybe you should explain what you mean by normalised...in words.

And if you didn't want this maybe you should have specified?
Umm... that normalises a vector to have magnitude 1. That can't be directly applied to a cube. Explain what you mean by "normalised".
I'm finding you quite offensive Jazzer008. Try to be civil ins$$anonymous$$d of throwing around comments. I'm here trying to help you and you are being quite rude about it. Frankly if I hadn't bothered your question probably would have disappeared in to the realms of UA unanswered...
The reason no-one understands is because you haven't made much sense - the "normalised cube" you're talking about isn't standard ter$$anonymous$$ology, and since that's the only thing you said, of course no-one knows what you're talking about. Try saying something along the lines of: "I want to normalise the position vectors of all the vertices of a cube such that it approximates a sphere", which is a more accurate description of what you want, and highlights why a standard Unity cube won't work (as only has 8 vertices).
As for how to do it, there is a free script hanging around somewhere that lets you export a mesh from Unity. If you first create a cube with enough vertices in a separate modelling program, you can then import it into Unity, run a script to deform the mesh, and then export it using the aforementioned script, you can use the exported model for what you need.
Here is the answer and you won't like it.
Make a new project and scene. Use code to modify your cube, then Save the results into a separate object or prefab. Use that object/prefab in your other project. Look up Procedural Examples, everything you need should be in it.
I think you may have some terms confused. Normalization is used to clamp values to a specific range (0-1) with relative differences remaining intact (see http://en.wikipedia.org/wiki/Normalized_vector). Saying 'normalize a cube' does not make much sense, unless you're specifically referring to vertex normals.
The image you've linked to shows a subdivided cube rendering as a wireframe. Unity has a MeshTopology enum that can be used to build meshes using (among other things) lines. Here is a quick example showing the use of this class. It creates a new menu item
GameObject->Create Other->Create Wireframe Cube
that builds a wireframe cube.
using UnityEngine;
using UnityEditor;
using System.Collections;
public class CreateWireframeCube : Editor {
[MenuItem("GameObject/Create Other/Wireframe Cube")]
public static void InitWireCube()
{
float scale = .5f;
Mesh m = new Mesh();
m.vertices = new Vector3[8]
{
new Vector3(-1f, -1f, 1f) * scale,
new Vector3(1f, -1f, 1f) * scale,
new Vector3(-1f, -1f, -1f) * scale,
new Vector3(1f, -1f, -1f) * scale,
new Vector3(-1f, 1f, 1f) * scale,
new Vector3(1f, 1f, 1f) * scale,
new Vector3(-1f, 1f, -1f) * scale,
new Vector3(1f, 1f, -1f) * scale
};
m.subMeshCount = 1;
m.uv = new Vector2[]
{
Vector2.zero,
Vector2.zero,
Vector2.zero,
Vector2.zero,
Vector2.zero,
Vector2.zero,
Vector2.zero,
Vector2.zero
};
m.SetIndices(
new int[]
{
0, 1,
1, 3,
3, 2,
2, 0,
0, 4,
1, 5,
2, 6,
3, 7,
4, 5,
5, 7,
7, 6,
6, 4
},
MeshTopology.Lines,
0
);
GameObject go = new GameObject();
go.AddComponent<MeshFilter>().sharedMesh = m;
go.AddComponent<MeshRenderer>();//.sharedMaterial.color = Color.green;
}
}

Thanks for the help but I'm looking to find a model cube that has had it's vertices Normalized.
You can see the difference between a normal cube and a cube that has had it's vertices normalized in the animated image I posted.
I think what is called a "normalized cube" is this "spherized" cube we see next to the regular cube. It could be done by code easily, in Unity script or by a script in Blender for example. Maybe this kind of primitive already exists in Blender.
I guess some people may called it 'spherized', but it's accomplished by passing the vertices through the normalize function. And yes I can easily do it in code, but my issue is that I don't want to spend any runtime generating the normalized cube, I want to have it pre-generated. :P
I've already checked blender, unfortunately either nothing exists or I've yet to find it, even function or modifier wise.
