◆ Open_LOD()

void Open_LOD ( int  level)

Allows user to open a LOD representation for the purpose of manually inserting a LOD.

Parameters
level- levelof LOD representation to be inserted

DETAILS

You use this function to query and or attached LODs to a particular segment or geometry. To call this function there must either be a currently open segment or shell. This way of opening LOD representations mirrors the interface for Open_Edge, Open_Face, and Open_Vertex, etc. After an LOD representation is open, you can make calls to insert any type of 3dGS geometry. Additionally, you can query the contents of any LOD level by using the Begin_Contents_Search() function and then using the returned HC_KEYs to access the LOD geometry. A call to Close_LOD must always terminate the operation. LODs can be either created by the application developer and manually attached or they can be automatically created by 3dGS' internal LOD generator. For further information on 3dGS' LOD generator you should refer to the 'lod' and 'lodo' suboptions of Set_Rendering_Options() .

NOTES

The "levels" LOD option in Set_Rendering_Options refers to the number of representations that will be computed for a given shell. In Open_LOD, "level" refers to a specific level within that list of representations.
