摘要： A three-dimensional image processing apparatus and method wherein a three-dimensional digital image in a three-dimensional memory is cut and read out to perform image processing. Addresses of a two-dimensional digital differential analyzer are first calculated by ray tracing in a direction of a vector on one plane of a three plane coordinate system of a three-dimensional coordinate system, and then data of voxel columns, arranged perpendicularly to the one plane coordinate system in the three-dimensional space along straight lines perpendicular to the ray at the addresses, are read out in units of a column for the individual voxel columns from the three-dimensional memory. A pair of three-dimensional memories are utilized, and a writing operation of a three-dimensional digital image into one of the three-dimensional memories and a reading out operation of the voxel columns from the other three-dimensional memory are performed simultaneously in a parallel relationship.

摘要： The present invention provides a hybrid financing structure for renewable power facilities that reduces the cost of power supplied from such facilities. In a preferred embodiment, the hybrid financing structure combines low cost financing, e.g., bonds, available to governmental entities, e.g., municipalities, with tax benefits and similar benefits available to private entities to lower the cost of power supplied from a renewable power facility. The renewable power facility is owned and operated by a private company to take advantage of tax benefits and similar benefits available to the private sector. To further reduce costs, a municipality prepays for power supplied from the facility using low cost financing, e.g., tax exempt bonds, available to the municipality. The hybrid financing structure also includes a production tracking account that reduces risk associated with prepayment of fluctuating renewable power supplies for the municipality by notionally tracking actual power production against predicted levels.
