( Using DX 8 ) In efforts to speed up rendering, I want to vary Levels of Detail by changing the index buffer of an indexed triangle list. Also to further decrease the detail by using the same verticies in a line list, then a point list. Ex. LOD 1: ( Triangle List ) 0,1,10, 2,9,1, 10,1,9, 3,8,2, 9,2,8, 4,7,3, 8,3,7, 5,6,4, 7,4,6 LOD 2: ( Triangle List ) 0,2,9, 4,7,2, 9,2,7, 5,6,4, 7,4,6 LOD 3: ( Line List ) 0,1, 1,2, 2,3, 3,4, 4,5 LOD 4: ( Point List ) 0,1,2,3,4,5 Is this an adviseable method ? Or am I missing something with this approach. Guy

Sounds like a good enough plan to me.. although, you may want to change your list a bit like so:

LOD 2: ( Triangle List )
0,1,10,
1,8,3,
10,3,8,
3,5,6,
8,3,6

At least this way, you won''t lose the shape (if you do it your way, you''ll lose the shape of the object, and present "tears" in your drawing.

Thanks for the Input,

It looks like I''m on the right track now.
Because of the huge number of grass blades
I''m going to have to render, this level of
detail is going to play a major part in
rendering the grass landscape.
