=====================

Volume rendering by object space raymarching for Unity.

VolumeRendering.shader cut a volume each axes by _SliceMin, _SliceMax properties.

## Object space raymarching

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)

## Slice axes rotation

By setting an axis quaternion in VolumeRendering component, 
you can cut a volume from arbitrary angles.

## VolumeAssetBuilder

Menu : Window -> VolumeAssetBuilder

VolumeAssetBuilder builds a 3D texture asset from a pvm raw file. (volume raw data)

## Compatibility

tested on Unity 2017.2.8f1, windows10 (GTX 1060).
