Shape distortions of the triangular faces and subfaces
This function will return a value that is proportional to the irregularity of a triangonal face or subface. The ratio of the lengths of the shortest and the longest edges.
trishape(gridObj) ## S4 method for signature 'trigrid' trishape(gridObj) ## S4 method for signature 'hexagrid' trishape(gridObj)
The value is exactly 1 for an equilateral triangle, and becomes 0 as one of the edges approach 0.
A named numeric vector, one value for every face of the grid.
g <- trigrid(3) shape <- trishape(g)
