Index to Coordinates

The indices of each block represent its position in the model, indicating in which column, line, and level (IX, IY, and IZ) it is.

The indices must be integer values, starting with any value (for Marvin model, it was adopted the indices 1,1,1 for the first block).

The model’s origin must be placed at the bottom portion, starting to count from the minimum coordinates at X, Y, and Z.

Figure 1 highlights the origin of the Marvin block model and the first block index coordinates (1,1,1).

However, if the block model contains geo-referenced information based on coordinates, they could be converted into indices before being imported to MiningMath.

To perform this conversion, check the following demonstration on how to convert coordinates into indices using data from Figure 2 and the equation from Figure 3.
