Hi
Is there a known problem with using the GeRayCollider class on the 2D viewports?

    
    
    
    
     if (rc->GetNearestIntersection(&res))  
     {
    
    
    
    
     GePrint("Detected");  
     }

On the perspective viewport, 'Detected' always prints when mouse cursor is over object.
On 2D viewports, 'Detected' always prints using standard primitives like Sphere, but using my own model, it doesn't print Detected.
Its really strange and I dont know what is causing it

GeRayCollider shouldn't care about the viewports since it always operates in 3D. Have you checked that the values you send to it are sensible? (I.e. what's in 'res', the part of the code that we cannot see.)

After some experimenting around, I found its just the one model that is causing me problems. I dont know why the model would be a problem as its just a simple face mesh.
anyway, just incase you can see something not right here is my code

    
    
    
    
    Bool Toolplugin::GetCursorInfo(BaseDocument *doc, BaseContainer &data, BaseDraw *bd, Real x, Real y, BaseContainer &bc)  
    {
    
    
    
    
     GeRayCollider* rc=NULL;  
     GeRayColResult res;  
          
     rc = GeRayCollider::Alloc();  
     obj= doc->GetActiveObject();
    
    
    
    
     // Make sure RayCollider is there  
     if (!rc)  
     {  
      GePrint("ERROR - RayCollider not Initialized");  
      return FALSE;  
     }
    
    
    
    
       
     wtail = bd->SW(Vector(x,y,0));  
     whead = bd->SW(Vector(x,y,10000.0));  
     otail = (!obj->GetMg()) * wtail;  
     oray = (whead - wtail) ^ (!obj->GetMg());
    
    
    
    
      
     rc->Init(obj,TRUE);  
     rc->Intersect(otail, !oray, 10000.0);  
       
       
     if (rc->GetNearestIntersection(&res))  
     {  
        
      GePrint("Detected: " + LongToString(res.face_id));   
        
     }
    
    
    
    
     return TRUE;  
    }
