IG_vect_3DIV_isosurface

This function takes a multi-page image and extracts the 3D surface into a vector image, based on the options specified by lpOptions.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_vect_3DIV_isosurface( HMIGEAR hMIGear, AT_VECT_3DIV_OPTIONS* lpOptions, LPHIGEAR lphIGear );

Arguments:

Name	Type	Description
hMIGear	HMIGEAR	A handle to a multi-page image, which has slices of images in a 3D series stacked together in the desired order.
lpOptions	AT_VECT_3DIV_OPTIONS*	A pointer to a structure AT_VECT_3DIV_OPTIONS, which contains all the calculation options for isosurface algorithm.
lphIGear	LPHIGEAR	The vector image with all the triangles generated.

Return Value:

Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

All pixel formats supported by ImageGear Professional.

Dimensions, color spaces, and bit depths must be the same for all pages. If the pages are not grayscale, they will be converted to IG_COLOR_SPACE_ID_Gy color space, so their color space will change after calling this function.

Sample:

Medical

Example:

	Copy Code
HMIGEAR hMIGear; /* Handle to a multi-page image / HIGEAR hIGear; / Handle for the generated vector image with all the triangles / AT_VECT_3DIV_OPTIONS vect3DIVOptions;/ Struct for calculation options / int nErrCount; / Returned count of errors / / If necessary, load the set of single-page images into hMIGear / ...... / Initialize vect3DIVOptions with proper values */ vect3DIVOptions.dIsoValue = 120.0; ... vect3DIVOptions.bDoNorms = TRUE; ... nErrCount = IG_vect_3DIV_isosurface(hMIGear, &vect3DIVOptions, &hIGear);

Copy Code

HMIGEAR hMIGear; /* Handle to a multi-page image */
HIGEAR hIGear; /* Handle for the generated vector image with all the triangles */
AT_VECT_3DIV_OPTIONS vect3DIVOptions;/* Struct for calculation options */
int nErrCount; /* Returned count of errors */
/* If necessary, load the set of single-page images into hMIGear */
......
/* Initialize vect3DIVOptions with proper values */
vect3DIVOptions.dIsoValue = 120.0;
...
vect3DIVOptions.bDoNorms = TRUE;
...
nErrCount = IG_vect_3DIV_isosurface(hMIGear, &vect3DIVOptions, &hIGear);

Remarks:

The pages in the multi-page image must be in the desired order as it would be in the 3D object. If the user has a series of single-page images to start with, necessary operations are needed to stack those single-page images together to form a multi-page image.
