Member Function Documentation

virtual signed int IPolygonUtilContext::AskInterface ( const BGUID *  piid, IRoot **  ppr  )

pure virtual

Queries this object to see if the interface piid is supported and returns the result in ppr.

Parameters

piid	The BGUID of the requested interface.
ppr	The address of an IRoot pointer which will receive the new interface.

Returns

S_OK if the interface is supported. E_FAIL if it is not.

Implements IRoot.

virtual signed int IPolygonUtilContext::DecRef ( )

pure virtual

Decreases the reference count on this object by 1. If the reference count reaches 0, the object is deallocated.

Implements IRoot.

virtual signed int IPolygonUtilContext::ExtractPolygons ( IVertexCallListContext *  pDestination, POLYGON_EXTRACT_PARAMS *  pep, IVolumeDataContext *  pData, IOctreeContext *  pOctree  )

pure virtual

Extracts a collection of polygons at the specified threshold and store the result in an IVertexCallListContext.

Parameters

[in,out]	pDestination	A previously created IVertexCallListContext that will get the results of the routine. Note that any contents previously contained in this object will be overwritten.
[in]	pep	The address of a POLYGON_EXTRACT_PARAMS structure initialized with the desired parameters for this function.
[in]	pData	The dataset to use for threshold extraction.
[in]	pOctree	The octree that was built from pData. This must be a valid octree, as the surface extraction routine requires this information to speed up the process.

virtual signed int IPolygonUtilContext::GetID ( signed long long *  id )

pure virtual

Returns the integer that represents the server side object that contains the octree.

virtual signed int IPolygonUtilContext::IncRef ( )

pure virtual

Increases the reference count on this object by 1. You do not need to call this after an object is first created. It is 1 by default.

Implements IRoot.

virtual signed int IPolygonUtilContext::LoadOBJ ( char *  filename, IVertexCallListContext *  pvcl, ENUM_PU_SMOOTH_MODES  smoothMode  )

pure virtual

Loads an OBJ (Wavefront's Advanced Visualizer) file into an IVertexCallList.

Parameters

filename	File to be loaded.
pvcl	IVertexCallList representation of the input file
smoothMode	The smoothing mode to apply to this object once it is loaded. See the documentation for ENUM_PU_SMOOTH_MODES for more detail.

virtual signed int IPolygonUtilContext::LoadOBJWithTextureMap ( char *  filename, char *  texture, IVertexCallListContext *  pvcl, ENUM_PU_SMOOTH_MODES  smoothMode  )

pure virtual

Loads an OBJ file and an associated JPG file to use as a virtual texture map. True texture mapping is not supported by this function. Instead, the mesh's vertex colors are set to the equivalet texture color as specified by the mesh's UV texture coords. As a result, high resolution textures mapped to a mesh region of low vertex density will exhibit loss of texture detail.

Parameters

filename	File to be loaded.
texture	Texture image file to be loaded (JPG only).
pvcl	IVertexCallList representation of the input file
smoothMode	The smoothing mode to apply to this object once it is loaded. SMOOTH_MODE_AUTO is required for this function.

virtual signed int IPolygonUtilContext::LoadSTL ( char *  filename, IVertexCallListContext *  pvcl, ENUM_PU_SMOOTH_MODES  smoothMode  )

pure virtual

Loads an STL file into an IVertexCallList.

Parameters

filename	File to be loaded.
pvcl	IVertexCallList representation of the input file
smoothMode	The smoothing mode to apply to this object once it is loaded. See the documentation for ENUM_PU_SMOOTH_MODES for more detail.

virtual signed int IPolygonUtilContext::ReleaseSessionResources ( )

pure virtual

Call this if you wish to free up server resources for this object before disconnecting.

virtual signed int IPolygonUtilContext::SaveOBJ ( char *  filename, IVertexCallListContext *  pvcl  )

pure virtual

Placeholder for SaveOBJ()

virtual signed int IPolygonUtilContext::SavePLY ( char *  filename, IVertexCallListContext *  pvcl  )

pure virtual

Placeholder for SavePLY()

virtual signed int IPolygonUtilContext::SaveSTL ( char *  filename, IVertexCallListContext *  pvcl  )

pure virtual

Placeholder for SaveSTL()
