Detailed Description

Picking information structure.

This class holds information related to the picking action on a renderer. The intersection info (Position and Normal) won't be accurate for the following type of models:

Locators: Camera, Lights, Marker and etc.
Custom Model inherited from FBModel.
And GPU skinned models.

Sample C++ code:

FBPickInfosList lList;
FBSystem lSystem;
FBRenderer* lRenderer = lSystem.Renderer;
lRenderer->Pick( 200, 200, lList );
 
int lIdx;
for( lIdx = 0; lIdx < lList.GetCount(); ++lIdx )
{
    FBString lName = "aNull ";
    lName += (char*)lList[lIdx].mModel->Name;
 
    FBModelNull* lNull = new FBModelNull( lName );
    lNull->Visible = true;
    lNull->Translation = lList[lIdx].mPoint;
}
