A set of Unity Game Engine scripts that generate a QuadSphere (a sphere made up of a mesh cube whose vertices are adjusted into a spherical shape) with QuadTree-based level of detail support.
- Create an Empty Game Object and add the QuadSphere script to it
- within the QuadSphere script, add some other game object that will be used to detect distances to the Quads in the QuadSphere
- Set the Starting Subdivisions Per Quad to some odd number greater than 0 (11 is a good starting point)
- Set the Radius to the desired radius for the Sphere
- in the Subdivision Distances array, select a size for the number of levels of subdivision you desire (10 is a good starting point)
- starting from array index 0, add the distances to the QuadSphere that should cause it to subdivide to a higher level of detail (distances will never be less than the distance from the centre of a Quad to the corner so you can enter 1 for all values to achieve the look seen in the above image)
- if you wish to add a Material to the Sphere you can start from the existing example materials
- if the Use Noise For Elevation tickbox is not selected, the Height Map (ParallaxMap) from the image will be used
