Source code: pfbounds.cxx
pfbounds will compute and print the bounding box of each object given on the command line. This can be useful for checking the size of an object, and determining whether it is centered around the proper point. pfbounds also uses pfdPrintSceneGraphStats() to determine the number of triangles in each object.
Source code: pftransform.cxx
pftransform will transform an object - translating, rotating, and/or scaling it - and save the transformed object back out in a new file. The -t option translates the model; -r rotates by the given Euler angles; -s does a uniform scale, while -s3 scales separately in X, Y, and Z. The transformation is done using a matrix created from a pfCoord for the translation and rotation, with the scaling pre-multiplied. Hence the order for the transformations is that used for a pfCoord; the order of the options on the command line has no effect.
