Detailed Description

class HBaseModel

The HBaseModel class is used to store and manage model information.

HBaseModel provides functions which facilitate creation and management of the graphical information associated with the model. It is typically referenced by an HBaseView object, which defines a specific view of the model.

The class encapsulates a HOOPS Include Library segment. This segment is intended to be used as the root of a HOOPS tree containing segments and geometry which represent graphical information for the application-specific model. A file can be read into it, or geometry can be created within a segment hierarchy beneath it.

Public Functions

HBaseModel(char const *model = 0): Constructs an HBaseModel object.

virtual ~HBaseModel(): Deletes the HOOPS segment tree associated with the model.

virtual void Init(): Initializes an HBaseModel object.

virtual void Flush(): Flushes the HOOPS segment tree associated with the HBaseModel object.

inline bool GetObjectCheck() const

Returns: A boolean indicating whether to scan model for annotations and other objects.

bool GetLMVModel() const: Returns the existence of a LMV model at the root of the model segment.

inline bool GetFirstFitComplete() const

Returns: A boolean indicating whether HBaseModel has called FitWorld on this model after the last call to Read(). It is not useful for model with multiple views.

inline void SetFirstFitComplete(bool value): Sets the boolean indicating whether the first call to FitWorld has been performed.

inline bool GetContainsDouble() const

Returns: A boolean indicating whether this model contains double precision attributes. This is set by Visualize on import.

inline void SetContainsDouble(bool value): Sets the boolean indicating whether this model contains double precision attributes.

virtual HFileIOResult Read(__wchar_t const *FileName, HBaseView *pHView = 0, bool clean_include = true, HInputHandlerOptions *options = 0)

Based on file extention this method loads the content of a file using HInputHandler found in the HIOManager from HDB If no handler is found, it will return InputNotHandled. It does not Flush existing geometry. The default extention is hmf if no other is found.

Parameters

FileName – A character pointer denoting the name of the file to be read in
pHView – A pointer to the HBaseView object containing the view-dependent information reading in the model
clean_include – if true, then includes are moved to unique include location after loading
options – An optional pointer to an instance of a HInputHandlerOptions contain extra data for input operation.

Returns

HFileInputResult with result of the attempted file read.

inline virtual HFileIOResult Read(char const *FileName, HBaseView *pHView = 0, bool clean_include = true, HInputHandlerOptions *options = 0)

virtual HFileIOResult WriteWithOptions(__wchar_t const *FileName, HBaseView *pHView = 0, HOutputHandlerOptions *options = 0)

Reads the visualization contents of the file into the HOOPS segment tree (visualization contents refers to graphical information/attributes). The segment tree will be created underneath the segment denoted by m_ModelKey. The HIO handler registered to handle the specified file extension will be used for import.

  This function can be overloaded to support reading of additional file types.
  \param FileName A character pointer denoting the name of the file to write
  \param pHView A pointer to the HBaseView object containing the view-dependent information
  \param options An optional pointer to an instance of a HOutputHandlerOptions contain extra data for output operation.
  \return HFileOutputResult with result of the attempted file write.

inline virtual HFileIOResult WriteWithOptions(char const *FileName, HBaseView *pHView = 0, HOutputHandlerOptions *options = 0)

virtual HFileIOResult Write(__wchar_t const *FileName, HBaseView *pHView = 0, float width = 0, float height = 0)

Writes the contents of the HOOPS segment tree to a file. The HOOPS segment tree beginning with the segment denoted by m_ModelKey will be written. The HIO handler registered to handle the specified file extension will be used for export.

This function should be overloaded to support writing of additional file types.

Note

for the ‘.pdf’ file extension, a 2D-PDF will be exported by default.

Parameters

FileName – A character pointer denoting the name of the file to write
pHView – A pointer to the HBaseView object containing the view-dependent information
width – For 2D or ‘paper’ export formats, the m_Window_Width and m_Paper_Width are set to ‘width’. For image formats, the width of the actual image in pixels will be ‘width’ * m_Image_Dpi. Default is 0.
height – For 2D or ‘paper’ export formats, the m_Window_Height and m_Paper_Height are set to ‘height’. For image formats, the height of the actual image in pixels will be ‘height’ * m_Image_Dpi. Default is 0.

Returns

HFileOutputResult with result of the attempted file write.

inline virtual HFileIOResult Write(char const *FileName, HBaseView *pHView = 0, float width = 0, float height = 0)

HModelInfo *GetHModelInfo() const

Returns: A pointer to the HModelInfo object with the current model info.

inline virtual HStreamFileToolkit *GetStreamFileTK() const

Returns: A pointer to the stream toolkit object used with this model for writing and reading HSF files.

inline virtual HC_KEY GetModelKey() const

Returns: The key of the encapsulated HOOPS segment denoting the top of the model hierarchy .

inline virtual HC_KEY GetModelIncludeKey() const

inline virtual HC_KEY GetBBoxKey() const

Returns: The key of the HOOPS segment containing the model’s bounding box geometry.

inline virtual bool IsBRepGeometry() const

Returns: A boolean indicating whether data originated from a CAD dataset. This is used so that we do not use HOOPS’ edges for display but rather the polylines which are provided by the modeller. This is set by setting a User_Option of 1 in the root of your scene-graph. This is automatically set if the data originated from ACIS or Parasolid and you used the framework to generate the file.

inline virtual bool IsFEAGeometry() const

Returns: A boolean indicating whether data originated from a FEA dataset. Developers ensure that this flag is automatically set if a User_Option of 2 is set in the root node of their scene-graph.

inline virtual void SetFEAGeometry(bool fea): This method indicates if the model represents finite-element data. Pass true if yes and false if otherwise.

inline virtual bool IsVectorGeometry() const

Returns: A boolean indicating whether the data is only vector data. This allows HOOPS to force vector printing always and not turn on shading. This is set by setting a User_Option of 3 in the root of your scene-graph.

inline virtual void SetVectorGeometry(bool vector): This method indicates if the model only contains vector data. Pass true if yes and false if otherwise.

virtual void CleanIncludes(): Utility function which moves global includes to model specific include segments.
