At last I installed Visual studio 8 into my Computer. So I can utilize Mutating Algorithms. With mac I increase very much performance. I use the function doLoadModel modified like below but I have an error when I call MergeTriMeshes function. An example of file is at www.interstudio.net/quesa/Roof.3DMF Have you some idea? //============================================================================= // doLoadModel : Loads a Model from File //----------------------------------------------------------------------------- static TQ3Object doLoadModel(TQ3ViewObject theView) { TQ3StorageObject storageObj; TQ3Object notOptimizedModel,theModel; float xBounds, yBounds, zBounds, scaleFactor; TQ3BoundingBox theBounds; TQ3Vector3D translateToOrigin = { 0.0f, 0.0f, 0.0f }; TQ3Matrix4x4 translateMatrix; TQ3Matrix4x4 scaleMatrix; TextureImporterProcPtr funcPtr = TextureImportCallback; TQ3BoundingBox dummyBounds; // Get the file storageObj = Qut_SelectMetafileToOpen(); if( storageObj == NULL ) return NULL; // Attach texture import callback in case this is VRML. #if !TARGET_API_MAC_OS8 Q3Object_SetProperty( storageObj, kTextureImportCallbackPropertyType, sizeof(TextureImporterProcPtr), &funcPtr ); #endif // Read the file (note, this disposes of storageObj) notOptimizedModel = Qut_ReadModel(storageObj); // Adjust the scale and translation required for the model // // Qut positions the camera 5 units away from the origin, with a hither-yon // distance of ~10 units.

The error prompt is:
Expression: vector subscript out the range
The problem is when there is a trimesh and edges are not definite.
I modify function MergeTrimeshList , I add
if(tmData.edges>0)
AppendArrayToVec(... ... ...)
It seem work fine.

I made a little modify ad the function: MergeTriMeshList
I think it is necessary initialize mergedEdges to NULL but I don't found
like do it.
.....
TQ3TriMeshEdgeData *pEdge;
int dimEdge=mergedEdges.size();
if (dimEdge>0)
pEdge=&mergedEdges[0];
else
pEdge=NULL;
TQ3TriMeshData mergedData = {
overallAtts.get(),
mergedFaces.size(),
&mergedFaces[0],
(mergedFaceNormals.size() == mergedFaces.size()? 1 : 0),
&faceAtt,
mergedEdges.size(),
pEdge,
0,
NULL,
mergedPoints.size(),
&mergedPoints[0],
vertAtts.size(),
&vertAtts[0],
theBounds
};

Error message is "vector subscript out of range" if mergedEdges.size()
is zero I write
TQ3TriMeshEdgeData *pEdge=NULL;
pEdge=&mergedEdges[0]; <---------------- ERROR
So I made the little modify. I don' t find other solution.

I checked in another modification to MergeTriMeshList.cpp. Let me know if you get any more errors. |

Did you get an error message about this? I don't know what you mean by
"I don't found like do it".

I have not checked out for about a year (and do not want to), so maybe this has been fixed. I have two trigrids, one with a texture shader in is attribute set and the second one without. If I put them in a group I get the texture shader of the first displayed on the second one. If I put them both in their own display group this does not happen. If I make the groups 'inline' the problem comes back. Should Quesa save the graphic state, or at least the texture state, around each object in a group? Is there some resetting code missing? Am I just out of date? Roger |

Does it matter which renderer you use? It goes wrong with at least three renderers, so I think the problem is in Quesa's handling of the graphics state outside the sending of data to the renderer. I suspect it is not just Tri-grids, though it could be when the Tri-grids get converted to Tri-meshes. |

In fact a textured TriGrid gets cached as a group of triangles, not a TriMesh, and the problem was that it was an inline group. I've checked in a fix. |

Does this mean that if I have two triangle objects in an ordinary group, the first with a texture and the second without, that the same problem occurs? Maybe for a group generated from a TriGrid, the texture is loose in the group before the triangles? |
