CheckWireframe(); Check the 3D graph wire frame |
|
ClearWireframe(); Clear the 3D graph wire frame |
|
DrawWireframe(); Draw 3D wire frame |
|
GetWireFrameBounds(); Get Wire Frame Bounds |
This function tests the wire frame points for possible INT32 overflow. It verifies that none of the points that define the graph cube causes Transform3DPoint to overflow. |

Syntax: |
BOOLEAN16 PUBLIC |
|
Input: |
pGraph: Pointer to a graph object created by AllocGraphPtr() |
|
Return: |
BOOLEAN16: TRUE/FALSE |
|
TRUE= |
wire frame points are within safe range |
|
FALSE= |
points overflow |
|
Example: |
/* CheckWireframe is TRUE if none of the 17 wire |

This function is an access routine that allows the caller to tell the charting engine to initialize the 3D-wire frame again. All 3D charts provide true 3D viewing, with 16 preset viewing angles. Your application can control 2D panning in X and Y, perspective panning and distortion, zoom, rotation around the X, Y and Z axes, and the size of the cube area that contains the chart. The thickness of the walls, floor, and risers can also be controlled by your application. The A3D_CUSTOMVIEW and A3D_VIEWANGLES attributes apply the viewing, panning, rotation, etc. characteristics to the 3D cube. This function tells the charting engine that the 3D-wire frame needs to be re-initialized. |

Syntax: |
void PUBLIC ClearWireframe (GraphPtr pGraph); |
Input: |
pGraph: Pointer to a graph object created by AllocGraphPtr() |
Return: |
None |
Notes: |
This function is called by the 3D-view tool code after erasing. |

This function erases the current 3D wire frame (if it is displayed) and redraws it in the new location. All 3D charts provide true 3D viewing, with 16 preset viewing angles. Your application can control 2D panning in X and Y, perspective panning and distortion, zoom, rotation around the X, Y and Z axes, and the size of the cube area that contains the chart. The thickness of the walls, floor, and risers can also be controlled by your application. The A3D_CUSTOMVIEW and A3D_VIEWANGLES attributes apply the viewing, panning, rotation, etc. characteristics to the 3D cube. This function erases and redraws the 3D-wire frame to show the results of these 3D viewing operations. |

GetWireFrameBounds() is an access routine that allows the caller to get the bounding rectangle of the wire frame in virtual coordinates as it appears on screen. |
|
Syntax: |
BOOLEAN16 PUBLIC |
Input: |
pGraph: A graph pointer allocated by AllocGraphPtr() |
pRect: Pointer to a rectangle data structure where the bounds (in virtual coordinates) of the wire frame can be stored. See the Rect structure in Appendix A. |
|
Return: |
BOOLEAN16: TRUE |
