Detailed Description

This is a wrapper around our low level HW mesh.

This is a interface around our low level vertex buffer this will allow you to directly update the low level buffers without recreating them, draw the buffers, and also give you access to release the buffers. This hides the actual vertex and index buffer away from the coder since it may be different depending on the device. Each GFX_MESH::HWMesh has a pointer to one of these. It has a simple reference counter to know when to get deleted since these can be batched up to be drawn and could potentially get deleted before the actual draw.

Constructor & Destructor Documentation

IHWDrawMesh()

DllExport IHWDrawMesh

(

)

Constructor.

~IHWDrawMesh()

virtual ~IHWDrawMesh ( )

inlinevirtual

{ ; }

Member Function Documentation

Draw()

virtual void Draw ( GraphicsWindow *  gw, DWORD  attribute  )

pure virtual

This draws the mesh to the display using the current render limits.

Parameters

gw	the graphics window to draw the mesh to.
attribute	if this mesh contains multiple matIDs this is which matID to draw. The old hwmesh stored multiple matIDs per mesh the new one only has one.

Implemented in HWTupleMeshContainer.

UpdateVertexBuffer()

virtual void UpdateVertexBuffer ( Point3 *  vertexList, Point3 *  gfxNormalList, Point3 *  faceNormalList, BitArray &  changedVerts, int  count, unsigned int *  vertMapList, int *  normalsMapList  )

pure virtual

Allows you direct access to the low level buffer to change values without recreating the mesh.

Parameters

vertexList	This is a pointer of all the vertices on the mesh. The changed vertices should be in the list
gfxNormalList	This is a pointer of all the gfx normals on the mesh. The changed vertices should be in the list
faceNormalList	This is a pointer of all the face normals on the mesh
changedVerts	This is a bitarray that tags which vertices are changed so we only update those vertices
count	This is number of vertices in vertex List
vertMapList	This is mapping that lets the HW vertex look up which vertex it belongs to
normalsMapList	This is mapping that lets the HW vertex look up which normal it belongs to. If this value is negative it is made positive and then face normallist is used to lookup the normal This occurs when there is no smoothing group.

Implemented in HWTupleMeshContainer.

Release()

virtual void Release ( )

pure virtual

This releases the buffers if the class is no longer referenced by anything. You should not delete this class but call Release on it.

Implemented in HWTupleMeshContainer.

MakeRef()

DllExport void MakeRef

(

)

When ever you reference this pointer and want to hang onto it you need to call this.

DecRefCount()

DllExport void DecRefCount ( )

protected

You should not typically call this but should call release when you are done with the pointer

.

CanDelete()

DllExport bool CanDelete ( )

protected

returns whether the class can be deleted ie the ref count is zero
