** OpenSim ジオラマ　開発用 [#w8cfb9a8]
 AddDynamicTextureURL()
 RenderPlugins[contentType].AsyncConvertUrl(updater.UpdaterID, url, extraParams);
    contentType を持つモジュールの AsyncConvertUrl() を呼び出す．


*** RenderTerrainScale [#o1907c41]
- void LLDrawPoolTerrain::renderFullShader() の sDetailScale
- デフォルトは 7, テクスチャは （リージョンサイズ/7） 個繰り返し表示される．1/7 = 0.14285714
- UVMap は (リージョンサイズ/7) 倍される．
- 256にすれば，1枚の画像．


*** Terrain Texture [#ta44cfc7]
- llviewerregion.cpp
-- void LLViewerRegion::unpackRegionHandshake()
--- Texture のUUID をセット 

- Render
-- pipeline.cpp  LLPipeline::renderGeom(LLCamera& camera, BOOL forceVBOUpdate)
--- p->reander(i)
---- lldrawpoolterrain.cpp   LLDrawPoolTerrain::render(S32 pass)
