| Geometry Defines the scene graph for a NWN model |
| Syntax: beginmodelgeom [model_name] Properties Nodes endmodelgeom [model_name]
|
| Description: This section defines the model's scene graph. This is a tree with several different types of nodes, although this section is refered to as geometry some of these node types contain other types of data. This section begins with a beginmodelgeom statement and ends with a endmodelgeom statement. Between these statements are node definitions for each node in the tree.
|
| Properties: The following three properties appear only in gidy_intlight.mdl, which is a tile class model provided with the viewer. They do not appear in the spells which are also classed as tiles. Their purpose is unknown. bmin [int] [int] [int] - Unknown bmax [int] [int] [int] - Unknown radius [int] - Unknown
|
| Nodes: Nodes are combined to form the scene graph. A list of nodes appear between the beginmodelgeom and endmodelgeom statements. The following types of nodes appear in the models we have seen. Dummy Node - This node contains no geometric or light data. However it can be used as a parent node and it's children may possibly inherit some properties. This represents a group in MAX. Trimesh Node - This is geometric data for the models. Light Node - Represents a light source. Patch Node - Unknown. (found in a_ba_casts.mdl) It seems to have the same properties as dummy. Emitter Node - Represents a particle emitter. Reference Node - Reference to an external model file.
