Detailed Description

This class contains arrays of vertex attributes for meshes and shells.

Remarks

VertexData objects are optional; they can be optionally passed to OdGiWorldGeometry and OdGiViewportGeometry when using their mesh and shell methods.

Setting an 'improper' size of any array will cause unpredictable or fatal results.

Constructor & Destructor Documentation

OdGiVertexData()

OdGiVertexData::OdGiVertexData ( )

inline

Default constructor for the OdGiVertexData class. Sets normals, colors and mapping coordinates to NULL and the orientation flag to kOdGiNoOrientation.

Definition at line 643 of file GiGeometry.h.

Member Function Documentation

mappingCoords()

const OdGePoint3d * OdGiVertexData::mappingCoords ( MapChannel  channel ) const

inline

Returns the array of mapping coordinates used by this object.

Parameters

channel

[in] Specifies mapping channel.

Returns

pointer to an array of mapping coordinates.

Remarks

This function does not make a copy of the array, which should have the same number of elements as the mesh or shell with which it is used. Writing beyond the array bounds will have unpredictable or fatal consequences.

Definition at line 767 of file GiGeometry.h.

normals()

const OdGeVector3d * OdGiVertexData::normals ( ) const

inline

Returns the array of vertex normal vectors used by this object.

Returns

pointer to an array of vertex normals.

Remarks

This function does not make a copy of the array, which should have the same number of elements as the mesh or shell with which it is used. Writing beyond the array bounds will have unpredictable or fatal consequences.

Definition at line 724 of file GiGeometry.h.

orientationFlag()

OdGiOrientationType OdGiVertexData::orientationFlag ( ) const

inline

Returns the direction of the normal at the vertices that is used by this object.

Returns

orientationFlag which can be one of the following:

Value kOdGiCounterClockwise -1 kOdGiNoOrientation 0 kOdGiClockwise 1

Definition at line 739 of file GiGeometry.h.

setMappingCoords()

void OdGiVertexData::setMappingCoords ( MapChannel  channel, const OdGePoint3d *  coords  )

inline

Sets the mapping coordinates to be used by this object.

Parameters

channel	[in] Specifies mapping channel.
coords	[in] Array of OdGePoint3d objects.

Remarks

This function does not make a copy of the array, which should have the same number of elements as the mesh or shell with which it is used. An incorrect number of elements will have unpredictable or fatal consequences.

setNormals()

void OdGiVertexData::setNormals ( const OdGeVector3d *  normals )

inline

Sets the vertex normal vectors to be used by this object.

Parameters

normals

[in] Array of normal vectors.

Remarks

This function does not make a copy of the array, which should have the same number of elements as the mesh or shell with which it is used. An incorrect number of elements will have unpredictable or fatal consequences.

Definition at line 664 of file GiGeometry.h.

setOrientationFlag()

void OdGiVertexData::setOrientationFlag ( const OdGiOrientationType  orientationType )

inline

Sets the orientation type to be used by this object.

Parameters

orientationType

[in] Orientation type.

Remarks

The orientation type defines the positive direction of the normal at the vertices.

orientationType must be one of the following:

Value kOdGiCounterClockwise -1 kOdGiNoOrientation 0 kOdGiClockwise 1

Definition at line 684 of file GiGeometry.h.

setTrueColors()

void OdGiVertexData::setTrueColors ( const OdCmEntityColor *  colors )

inline

Sets the vertex colors to be used by this object.

Parameters

colors

[in] Array of OdCmEntityColor objects.

Remarks

This function does not make a copy of the array, which should have the same number of elements as the mesh or shell with which it is used. An incorrect number of elements will have unpredictable or fatal consequences.

trueColors()

const OdCmEntityColor * OdGiVertexData::trueColors ( ) const

inline

Returns the array of vertex colors used by this object.

Returns

pointer to an array of vertex colors.

Remarks

This function does not make a copy of the array, which should have the same number of elements as the mesh or shell with which it is used. Writing beyond the array bounds will have unpredictable or fatal consequences.
