4 Q3Mesh_DelayUpdates

You can use the Q3Mesh_DelayUpdates function to prevent QuickDraw3D from updating its internal list of mesh components.

TQ3Status Q3Mesh_DelayUpdates (TQ3GeometryObject mesh);
mesh A mesh.

DESCRIPTION


The Q3Mesh_DelayUpdates function prevents QuickDraw3D from updating its internal list of components and maintaining correct face orientation (that is, vertex ordering) for the mesh specified by the mesh parameter. Updating the list of components can consume significant amounts of time, and it might be useful temporarily to prevent component list updating. You should later call Q3Mesh_ResumeUpdates to resume component list updating. Generally, if you are creating or deleting a number of vertices or faces from a mesh, it is better to bracket the entire set of changes with calls to Q3Mesh_DelayUpdates and Q3Mesh_ResumeUpdates.
