Column processing

Column processing is a set of functions that act on individual columns of blocks in the block model. The columns may be in any of the principal orientations (i.e. X, Y or Z) and their sizes are those of the highest resolution (i.e. smallest sub-block) in the model.

In a rotated block model, column processing takes place in model space, along a column of blocks. Thus when defining the X, Y or Z to perform the column processing, care must be taken with a rotated model to achieve the desired result.

COLUMNS
Column Tops	Save the coordinates of the top of each column in a block model to a string file
Ore/Waste Discrimination	Classify blocks as ORE or WASTE
Dilution & Reduction	Apply dilution and reduction to ore/waste contacts and column tops and bottoms
Recoverable Product	Calculate the volume of recoverable product
Thicknesses	Save the thicknesses and length-weighted composite grades in a string file
