The Arithmetic module provides basic Add, Multiply, etc functions that operate on buffers.
Examples:
SoAlgorithms, SoConversion, SoConvolution, SoDataExtract, SoSeismic

Assumes the buffer contains a 3D array of values. However 1D and 2D arrays can be handled as degenerate cases. For example, to use a 1D array of length N and compute over the range I to J:
inputBuffer | The source buffer object. | |
dataType | The type of the data in the source buffer object. | |
arrayDim | Dimensions of the array (can be degenerate, e.g. N,1,1) | |
range | Subset of the array to consider | |
min,max | Result values |
