I’d be interested in that too. Mihir did you look into this? Any findings?

Hi, thanks for an interesting new take on terrain/LOD.

Perhaps a minor point: in your pseudo code for LODSelect(), isn’t it worth performing the FrustumIntersect() first?

That is, once a cell is out of view, is there any reason to consider it for LOD selection at all? In trying to implement the pseudo-code, it appeared as if some out-of-frustum cells were being added to the selection list, and performing the frustum test first seemed to fix this.

The paper says ‘While a detailed discussion of the topic of streaming is outside the scope of this article, some basics will be covered.’
Since I am a novice I wish to understand the details about streaming. Can you suggest any resources for it? I will be grateful.

Normal Map Texture is computed in basiccdlod approach before the vertices are morphed. Hence normal fecthed during rendering will be based on unmorphed terrain vertices. Hence normals fetched in the morphed region will not be accurate. Is it correct? If yes, any remedy for the same?

Actually, I meant Fabian Hahn’s link of C code. It is not working.

Hi Mihir,
Yes, a same/similar morphing technique is used to blend overlay maps in the pixel shader!

Hi Jaytirth,
The links seem to work fine now (for example, http://www.vertexasylum.com/downloads/cdlod/source.zip ) – maybe it was a temporary problem with the web server?

I am interested in reading your code but the source code link provided by you is dead.

Hi,
After reading streaming LOD code, the first impression i got is, LODs are generated for overlay maps in addition to heightmaps. Are we using morphing technique for overlay maps in pixel shader? (refering to albedoColor = lerp( albedoColor, parentAlbedoColor, LODMorphValue ) )
