Contours

 

These function are used to create "contour" lines around the TAG values on the 2D frames.

 

A contour is composed of a series of points on the frames and a series of "connectivity" informations that tell how the points are linked to create the contours loops.

 

The following functions are used to create, update and delete the contours.

 

 

Fct_Contour_Compute

 

Function to create the contours using all available threads.

 

Fct_Contour_Create

 

Function to create the contours on a single frame.

 

Fct_Contour_Update

 

Function to update any modified contours on a single frame

 

Fct_Contour_Free

 

Function to delete the contours and free the associated memory.

 

 

The following functions are used to get access to the contour information.

 

 

Fct_Contour_Get_Points

 

Functions that returns either the points of the points and their connectivity.

 

 

Fct_Contour_Get_Loops

 

 

 

The following functions are used to draw the contours.

 

 

Fct_Contour_Draw_Points

 

Functions to draw the points of the contours in an OpenGL window.
