Volume rendering by object space raymarching for Unity.
VolumeRendering.shader cut a volume each axes by _SliceMin, _SliceMax properties.
VolumeRendering component generates a Cube geometry which has 1.0 length edges. By object space raymarching techniques, rendering a volume with a MeshRenderer. (See references)
VolumeAssetBuilder builds a 3D texture asset from a pvm raw file. (volume raw data)
