How do you turn a cube into a sphere?

If you take a cube and:

1. In edit mode, subdivide it.
2. In object mode, scale it along one axis.
3. Back in edit mode scale it back down the axis so it looks like a cube again.
4. And then use Shift Alt S .. ‘To Sphere’

How do I edit spheres in blender?

The To Sphere transformation will give the selection spherical qualities. The Fig. Monkey with increasing sphericity. below shows the results of applying the To Sphere transformation to the monkey mesh….To Sphere.

How to render a sphere on a quad?

Luckily for this function that really just means a find and replace of vec with float. That function takes 3 arguments, the ro (ray origin), rd (normalized ray direction), and sph (sphere position xyz and radius w). It returns the length of the ray from the origin to the sphere surface, or a -1.0 in the case of a miss. Nice and straight forward.

How to make a sphere look like a cube in Unity?

Unity even includes a handy UnityWorldToClipPos () function to make it even easier. Then it’s a matter of having an output argument that uses SV_Depth with the clip space position’s z divided by its w. Put that all together with some basic lighting and you get something like this: It looks like a sphere, but it’s actually a cube. A very round cube.

Can a cube texture be converted to a sphere texture?

Unity can convert an imported equirectangular texture into a cube map for you. But that means you loose out on anisotropic filtering. The UVW for a cube map texture sample is essentially just the sphere’s normal.

What can a sphere be used for in a program?

Rendering spheres might be useful for testing your program but are limited indeed. But they can be useful in other contexts. For example spheres can be used to represent the overall volume of an object, as a bounding volume (figure 4).
