Modules
module	geomutilmodule

Functions/Subroutines
logical function, public	geomutilmodule::between (x, a, b)
	Check if a value is between two other values (inclusive). More...
logical function, public	geomutilmodule::point_in_polygon (x, y, poly)
	Check if a point is within a polygon. More...
integer(i4b) function, public	geomutilmodule::get_node (ilay, irow, icol, nlay, nrow, ncol)
	Get node number, given layer, row, and column indices for a structured grid. If any argument is invalid return -1. More...
subroutine, public	geomutilmodule::get_ijk (nodenumber, nrow, ncol, nlay, irow, icol, ilay)
	Get row, column and layer indices from node number and grid dimensions. If nodenumber is invalid, irow, icol, and ilay are -1. More...
subroutine, public	geomutilmodule::get_jk (nodenumber, ncpl, nlay, icpl, ilay)
	Get layer index and within-layer node index from node number and grid dimensions. If nodenumber is invalid, icpl and ilay are -1. More...
pure real(dp) function, dimension(2), public	geomutilmodule::skew (v, s, invert)
	Skew a 2D vector along the x-axis. More...
subroutine, public	geomutilmodule::transform (xin, yin, zin, xout, yout, zout, xorigin, yorigin, zorigin, sinrot, cosrot, invert)
	Apply a 3D translation and optional 2D rotation to coordinates. More...
subroutine, public	geomutilmodule::compose (xorigin, yorigin, zorigin, sinrot, cosrot, xorigin_new, yorigin_new, zorigin_new, sinrot_new, cosrot_new, invert)
	Apply a 3D translation and 2D rotation to an existing transformation. More...
subroutine	geomutilmodule::defaults (xorigin, yorigin, zorigin, sinrot, cosrot, invert, translate, rotate, xorigin_opt, yorigin_opt, zorigin_opt, sinrot_opt, cosrot_opt, invert_opt)
	Process arguments and set defaults. Internal use only. More...
real(dp) function, public	geomutilmodule::area (xv, yv, cw)
	Calculate polygon area, with vertices given in CW or CCW order. More...
subroutine, public	geomutilmodule::shared_face (iverts1, iverts2, iface)
	Find the lateral face shared by two cells. More...
subroutine, public	geomutilmodule::clamp_bary (alpha, beta, gamma, pad)
	Clamp barycentric coordinates to the interior of a triangle, with optional padding some minimum distance from any face. More...
