3D Graphics Programming with QuickDraw 3D 1.5.4

Creating and Editing Cones

QuickDraw 3D provides routines that you can use to create and manipulate cones. See "Cones" for the definition of a cone.

Q3Cone_New

You can use the Q3Cone_New function to create a new cone.



 
TQ3GeometryObject Q3Cone_New (const TQ3ConeData *coneData);

coneData: A pointer to a TQ3ConeData structure.

DESCRIPTION

The Q3Cone_New function returns, as its function result, a new cone having the shape and attributes specified by the coneData parameter. If a new cone could not be created, Q3Cone_New returns the value NULL .

Q3Cone_Submit

You can use the Q3Cone_Submit function to submit an immediate cone for drawing, picking, bounding, or writing.



 
TQ3Status Q3Cone_Submit (

                     const TQ3ConeData *coneData, 

                     TQ3ViewObject view);

coneData: A pointer to a TQ3ConeData structure.
view: A view.

DESCRIPTION

The Q3Cone_Submit function submits for drawing, picking, bounding, or writing the immediate cone whose shape and attribute set are specified by the coneData parameter. The cone is drawn, picked, bounded, or written according to the view characteristics specified in the view parameter.

SPECIAL CONSIDERATIONS

You should call this function only in a submitting loop.

Q3Cone_GetData

You can use the Q3Cone_GetData function to get the data that defines a cone and its attributes.



 
TQ3Status Q3Cone_GetData (TQ3GeometryObject cone, TQ3ConeData *coneData);

cone: A cone.
coneData: On exit, a pointer to a TQ3ConeData structure that contains information about the cone specified by the cone parameter.

DESCRIPTION

The Q3Cone_GetData function returns, through the coneData parameter, information about the cone specified by the cone parameter. QuickDraw 3D allocates memory for the TQ3ConeData structure internally; you must call Q3Cone_EmptyData to dispose of that memory.

Q3Cone_SetData

You can use the Q3Cone_SetData function to set the data that defines a cone and its attributes.



 
TQ3Status Q3Cone_SetData (

                     TQ3GeometryObject cone,

DESCRIPTION

The Q3Cone_SetData function sets the data associated with the cone specified by the cone parameter to the data specified by the coneData parameter.

Q3Cone_EmptyData

You can use the Q3Cone_EmptyData function to release the memory occupied by the data structure returned by a previous call to Q3Cone_GetData .



 
TQ3Status Q3Cone_EmptyData (TQ3ConeData *coneData);

coneData: A pointer to a TQ3ConeData structure.

DESCRIPTION

The Q3Cone_EmptyData function releases the memory occupied by the TQ3ConeData structure pointed to by the coneData parameter; that memory was allocated by a previous call to Q3Cone_GetData .
