The LinearFog leaf node defines fog distance parameters for linear fog. LinearFog extends the Fog node by adding a pair of distance values, in Z, at which the fog should start obscuring the scene and should maximally obscure the scene.
The front and back fog distances are defined in the local coordinate system of the node, but the actual fog equation will ideally take place in eye coordinates.
The linear fog blending factor, f, is computed as follows:

false, the value of each node's
