Constructors

this this(): Default constructor, doesn't allocate memory for height map
this this(CartesianSurface surface): Copy constructor, returns the exact copy of the given surface

Members

Functions

cellXIndex int cellXIndex(double x): Returns cell index from a given X coordinate. Maximum number is nx - 1 Returns -1 if a given coordinate is outside the surface
cellYIndex int cellYIndex(double y): Returns cell index from a given Y coordinate. Maximum number is ny - 1 Returns -1 if a given coordinate is outside the surface
dx double dx(): Returns surface increment (cell size) along X axis
dy double dy(): Returns surface increment (cell size) along Y axis
getZ double getZ(double x, double y): Returns z value of a point with given coordinate using bilinear interpolation
isInsideSurface bool isInsideSurface(double x, double y): Returns true if point with given coordinates is inside surface boundaries, otherwise returns false
nx int nx(): Returns number of nodes along X axis
ny int ny(): Returns number of nodes along Y axis
opBinary CartesianSurface opBinary(double rhs): Operators +, -, *, / overloading for a surface and a fixed value
opBinary CartesianSurface opBinary(CartesianSurface rhs): Operators +, -, *, / overloading for two surfaces
opOpAssign CartesianSurface opOpAssign(CartesianSurface rhs): Operators +=, -=, *=, /= overloading for two surfaces
opOpAssign CartesianSurface opOpAssign(double rhs): Operators +=, -=, *=, /= overloading for a surface and a fixed value
setHeader void setHeader(int nx, int ny, double xOrigin, double yOrigin, double dx, double dy): Sets surface header and allocates surface memory
xOrigin double xOrigin(): Returns X coordinate of surface origin
yOrigin double yOrigin(): Returns Y coordinate of surface origin
z Slice!(double*, 2) z(): Method to access height map.
