[Nebula-Discuss] Terrain renderers status

[Jack P. <ch...@gm...>]

Hi all,

There are:
nCTerrain2 - which looks like was used by RadonLabs in their SDK,
nCLODTerrain - another implementation of CLOD terrain?
nMap - ?

It looks like all of them are unmaintained for a some time
None of them compiled for me from the start (I use Visual Studio 2005).
After I spent some time on configuration, then a couple of days of debugging
and resource files manipulations, I managed to run them.

However, only nMap displays something and does not crush.

nCLODTerrain demo shows wheels, which fall on something invisible (should
be terrain, I suppose), but it is not rendered. And after some time crashes
with DX E_OUTOFMEMORY error on creating empty small-size texture
(D3D9Texture->CreateEmpty()). The program itself consumes less than 10Mb of
RAM at that moment...

ncTerrain2 had a bug with not initializing terrainScale (it was a random
huge number), then a probably bug with incorrect logic on asserting empty
mesh state (it supposed to be Valid after creating an empty mesh). After a
couple of days of struggling I managed to run it finaly, and a couple of
times it even displayed smth. like untextured terrain. Then I started to
play with size/scale, and now I am constantly receive E_OUTOFMEMORY from
nChunkLODMesh::CreateVertexBuffer() (which is
nD3D9Mesh::CreateVertexBuffer()), or from CreateEmptyTexture(), although
program consumes less than 10Mb of memory, and  buffers  supposed to be
created  are  of  reasonable size. Not sure if it is significant, but all
the calls in these failing cases are made by ResourseServer from a separate
thread.

If someone can explain current status of these project, or give a clue on
why this error appears, please do not hesitate to do that! Any information
will be appreciated.

Jack.
