Finally made some headway yesterday and today on getting the frustum corner vectors properly computed and transformed. This preliminary pixel shader is showing the ray interception at 47 km (1km below the actual hard deck) where we will start our marching!

The quiltwork shows the level 7 panels that make up the clouds based on UV coordinates derived from the fractional remainders of the level 7 scale.
