DXMakeImage

Function

Creates a new empty image Field.

Syntax

#include <dx/dx.h>


Field DXMakeImage(int width, int height)

Functional Details

Simplifies creating a Field that represents an image of the specified width and height.

An image Field is a regular 2-dimensional grid of "positions" and "connections," with a "colors" component that is floating-point, 3-vector. The sign of the deltas of the "positions" component determines the orientation of the image. This routine creates each of these components, adds them to a Field, and returns the Field.

The Field created can be deleted with DXDelete. See 4.2 , "Memory Management".

Return Value

Returns the image or returns NULL and sets an error code.
