Detailed Description
Maintains a Dx version of the current mesh in the cache. It will render either the 3ds Max mesh or a screen aligned quad.

Member Function Documentation
| static DllExport IRenderMesh* GetRenderMesh | ( | ) | [static] |
Exported function to access the IRenderMesh interface.
| virtual void SetMeshType | ( | MeshType | type | ) | [pure virtual] |
Defines what the mesh represents.
- Parameters:
-
type specify whether it is a mesh or a full screen quad
| virtual bool Evaluate | ( | LPVOID | Device, |
| int | width, | ||
| int | height, | ||
| int | texWidth, | ||
| int | texHeight | ||
| ) | [pure virtual] |
Used to update the Quad version of the mesh.
- Parameters:
-
*Device A Pointer to the main DX interface width The width of the render target height The height of the render target texWidth The width of the texture being used texHeight The height of the texture being used
- Returns:
- TRUE if successful
| virtual bool Evaluate | ( | LPVOID | Device, |
| Mesh * | aMesh, | ||
| int | MatIndex, | ||
| bool | NegScale | ||
| ) | [pure virtual] |
Setting the node parameter to non NULL, will make sure the Normals are transformed correctly.
- Parameters:
-
*Device A Pointer to the main DX interface *aMesh The mesh whose data is to be extracted MatIndex The material index for the faces to be rendered. This provides support for multi subobject materials NegScale Used to determine if negative scale is being used on the object.
- Returns:
- TRUE if successful
| virtual void SetMappingData | ( | Tab< int > & | map | ) | [pure virtual] |
Store relevant mapping data.
Allows the app to provide up to 8 mapping channels, this is used to extract the texcoord data from the mesh
- Parameters:
-
map A tab of active mapping channels
| virtual bool Render | ( | LPVOID | Device | ) | [pure virtual] |
Renders the current object.
- Parameters:
-
*Device A Pointer to the main DX interface
- Returns:
- TRUE if successful
| virtual void Invalidate | ( | ) | [pure virtual] |
force an invalidation of the internal data structures
| virtual bool GetVertexFormat | ( | void ** | pFormat, |
| int * | itemCount | ||
| ) | [pure virtual] |
Get the current Vertex format for the mesh.
This retrieves the current active vertex format for the mesh. The return value will be false if DirectX9 is running or true and an itemCount >0 if DirectX 10 is running.
- Parameters:
-
**pFormat A pointer to vertex descriptor - this will be different for Dx9 and Dx10 *itemCount The number of items in the vertex descriptor
- Returns:
- TRUE if successful. In Dx9 and 3ds Max 9 this will be false.
