Calculate average orientation patch count after several rotations
A function that calls OPC iteratively after rotating mesh a selected number of degrees around the Z-axis following Evans and Jernvall (2009) Patterns and constraints in carnivoran and rodent dental complexity and tooth size. J Vert Paleo 29:24A
OPCr(plyFile, Steps = 8, stepSize = 5.625, minimum_faces = 3, minimum_area = 0)
plyFile |
An object of classes 'mesh3d' and 'shape3d' with calculated normals |
Steps |
Number of iterations to run the OPC function on the mesh |
stepSize |
Amount of rotation in degrees about the Z-axis to adjust mesh surface by between each iteration of OPC |
minimum_faces |
Argument to pass to the OPC function |
minimum_area |
Argument to pass to the OPC function |
The function requires an object created by reading in a ply file utilizing either the read.ply or the read.AVIZO.ply function, with calculated normals.
Default number of Steps is 8, with a stepSize of 5.625 degrees, following the original definition of OPCR.
See the details for the OPC function for more information about preparing mesh surfaces and the effects of minimum_faces and minimum_area.
