Detailed Description

Function Documentation

void PShow_Net_Heuristics ( int  key_count,
const HC_KEY path_keys,
char *  list 
)

Similar to Show_Heuristics(), but returns the net effective settings along a discrete segment path.

Parameters
key_count- The size of pathkeys
path_keys- An array of HC_KEY's delineating a path of segments.
list- A list of the settings made in a previous call to Set_Heuristics(). Passed by reference. Returned to user.

DETAILS

As with all PShow_Net_* routines, pathkeys[0] represents the lowest (a.k.a the "most local" or "leaf"), and pathkeys[keycount-1] represents the highest segment. If the path is incomplete, missing segments are filled in if possible. Missing segments must be part of the same direct ancestry in order to be filled in. If the desired path contains an include link, the shortest unambiguous set of pathkeys would be [leaf, includelink, root], where includelink is the return value from Include_Segment().

By default, HOOPS will determine the Net attribute from the last specified key all the way to the root. If you add -1 at the end of the array, the PShow_Net routines will not proceed beyond the end of the last specified key.

For other details, see Show_Heuristics()

void PShow_One_Net_Heuristic ( int  count,
const HC_KEY keys,
const char *  type,
char *  value 
)

Similar to Show_One_Heuristic() but returns the net settings along a discrete path.

Parameters
count- The size of keys
keys- An array of HC_KEY's delineating a path of segments.
type- The type in type = value.
value- The value of type. Passed by reference. Returned to user.

DETAILS

By default, HOOPS will determine the Net attribute from the last specified key all the way to the root. If you add -1 at the end of the array, the PShow_Net routines will not proceed beyond the end of the last specified key. For additional details, see Set_Heuristics()

void Show_Heuristics ( char *  list)

Returns the heuristic settings that have been made on the currently open segment.

Parameters
list- A list of the settings made in a previous call to Set_Heuristics(). Passed by reference. Returned to user.
Options Returned:
backplane cull, clipping, concave polygons, culling, exclude bounding, detail selection, hidden surfaces, incremental updates, intersecting polygons, internal selection limit, partial erase, polygon crossings, polygon handedness, quick moves, related selection limit, selection sorting, visual selection

DETAILS

No additional details. See Set_Heuristics()

NOTES

The Show_Heuristics() routines return the actual attribute values stored in the particular segment at hand. The Show_Net_Heuristics routines return the effective attribute value for the specified segment. The distinction is that there may or may not be an "actual" stored value for an attribute for a given segment, but there is guaranteed always to be an effective value for every attribute for every segment. Also, "Show Net" will return the cumulative effects of those attributes that concatenate as you go up and down the segment tree (Modelling Matrices and Windows).

When the value being passed back is a string, be sure you've declared your string variable to be long enough.

In C, "passed by reference" means that you have to allocate an appropriate variable, either statically or off the stack, and pass a pointer to that variable to the HOOPS routine. To generate a pointer to a variable C, you prefix the variable with a "&". In other languages you normally don't have to do anything different from usual.

The Show_Heuristics() routines will complain if they're called and the attribute is not actually set in the segment. Use Show_Existence() to avoid this, if necessary.

void Show_One_Heuristic ( const char *  type,
char *  value 
)

Similar to Show_Heuristics() but returns a single setting, rather than the entire set.

Parameters
type- The type in type = value.
value- The value of type. Passed by reference. Returned to user.

No additional details. See Set_Heuristics()
