RemarksThe TerrainClipmapRenderer is a SceneNodeRenderer that handles TerrainNodes. It renders the BaseClipmap and DetailClipmap of the TerrainNode.
Render passes:
This renderer uses the Materials stored in the TerrainLayer. The
material needs a render pass called "Base" to render into the
BaseClipmap and a render pass called "Detail" to render into the
DetailClipmap. TerrainLayers can have render passes
for both, "Base" and "Detail".
Clipmap data:
The content of the clipmaps depends on the used materials. The materials of the
TerrainLayer material renders into the clipmap. The material of the
TerrainNode reads from the clipmap. These materials can be modified to store
different data in the clipmaps.
Per default, the BaseClipmap consists of one HalfVector4 texture which stores: (absolute terrain height, world space normal x, world space normal z, hole flag)
Per default, the DetailClipmap consists of three Color textures which store: (world space detail normal x, world space detail normal z, specular power, hole flag), (diffuse R, diffuse B, diffuse B, -), (specular intensity, height, -, -)
Render Target and Viewport:
This renderer changes the current render target of the graphics device because it uses the
graphics device to render into the clipmap render targets. The render target
and the viewport of the graphics device are undefined after rendering.
