Summary: Quesa Fails loading objects

Initial Comment:
The version of Quesa that is in CVS fails to load
objects in Bugdom. I am using an older (much older!)
version of Quesa in Bugdom now that loads these files
correctly. I'd really like to update to the latest
Quesa due to the speed improvements, but have not been
able to sort out why the files do not load.

I've attached the items that fail to load before the
project crashes to this report. My working copy of
Quesa is here in case anyone needs it again:

ftp://ftp.ifd.com/pub/Quesa_Bugdom.zip

Here is the function used to load the files:

/***************** READ 3DMF MODEL
************************/
//
// Reads the 3DMF file and saves into new struct
OpaqueTQ3Object*.
//
// INPUT:  file = File Object containing reference to
3DMF file
//
// OUTPUT: model =object containing all the important
data in the 3DMF file
//
//

static TQ3Status MyRead3DMFModel(TQ3FileObject file,
struct OpaqueTQ3Object* *model)
{
struct OpaqueTQ3Object*	myGroup;
struct OpaqueTQ3Object*		myObject;

		/* INIT MODEL TO BE RETURNED */
		
	*model = 0;												// assume return nothing
	myGroup = myObject = 0;
	

		/* OPEN THE FILE OBJECT & EXIT GRACEFULLY IF
UNSUCCESSFUL */

	if (Q3File_OpenRead(file,0) != kQ3Success)							//
open the file
		DoFatalAlert("Reading 3DMF file failed!");
	
				/**************************************/
				/* READ ALL THE OBJECTS FROM THE FILE */
				/**************************************/
	do
	{	
			/* READ A METAFILE OBJECT FROM THE FILE OBJECT */

		myObject = Q3File_ReadObject(file);
		if (myObject == 0)
		{
			if (myGroup)
				Q3Object_Dispose(myGroup);

			DoAlert("MyRead3DMFModel: Q3File_ReadObject Failed!");
			QD3D_ShowRecentError();
			break;
		}

		/* ADD ANY DRAWABLE OBJECTS TO A GROUP */
		
		if (Q3Object_IsDrawable(myObject))								// see if
is a drawable object
		{
			if (myGroup)												// if group exists
				Q3Group_AddObject(myGroup,myObject);					// add
object to group
			else
			if (*model == 0)											// if no model data yet /
this is first
			{
				*model = myObject;										// set model to this object
				myObject = 0;											// clear this object
			}
			else														// this isn't the first & only
object, so add to group
			{
				myGroup = Q3DisplayGroup_New();							// make new group
				if (myGroup == 0)
					DoFatalAlert("MyRead3DMFModel: Q3DisplayGroup_New
failed!");
				
				Q3Group_AddObject(myGroup,*model);						// add
existing model to group
				Q3Group_AddObject(myGroup,myObject);					// add
object to group
				Q3Object_Dispose(*model);								// dispose extra ref
				*model = myGroup;										// set return value to
the new group
			}
		}
		
		if (myObject != 0)											// dispose extra ref
			Q3Object_Dispose(myObject);
			
	} while(!Q3File_IsEndOfFile(file));
	
	
			/* SEE IF ANYTHING WENT WRONG */
			
	if (Q3Error_Get(0) != kQ3ErrorNone)
	{
		if (*model != 0)
		{
			Q3Object_Dispose(*model);
			*model = 0;
		}		
		return(kQ3Failure);
	}
	
	return(kQ3Success);
}

For some reason SF will not accept my attachments; probably
requires that I use IE on Windows XP or some ...

Anyway, I put the archive of the files that Quesa fails on
online:
