A3DGraphHatchingPatternLineData

struct A3DGraphHatchingPatternLineData

Line descriptor for the A3DGraphHatchingPatternData structure.

2.0

A hatching pattern is a composition of at least onen line descriptor. A line descriptor is represented by an instance of A3DGraphHatchingPatternLineData. Each hatching line is infinitely repeated in both orthogonal directions.

The fill pattern graphics style is described with an instance of A3DGraphStyleData which can be retrieved by calling A3DGlobalGetGraphStyleData with m_uiStyleIndex.

This structure is exclusively used as a composition of A3DGraphHatchingPatternData even if the hatching pattern is made of a single hatching line description.

HOOPS does not perform any check on whether the values of m_dAngle and m_sOffset generating infinitely overlapping lines. It is up to your application to make such validation if needed.

Variables

A3DVector2dData A3DGraphHatchingPatternLineData.m_sStart

A3DVector2dData

A point within the reference line. Expressed in 2D space coordinates.

A3DVector2dData A3DGraphHatchingPatternLineData.m_sOffset

A3DVector2dData

The distance between each successive line starting points. Expressed in 2D space coordinates.

A3DDouble A3DGraphHatchingPatternLineData.m_dAngle

A3DDouble

The direction of the lines. This value is expressed in radians, where an angle value of 0 represents an X-aligned line.

A3DUns32 A3DGraphHatchingPatternLineData.m_uiStyleIndex

A3DUns32

Global index for the drawing style (A3DGraphStyleData) of the pattern.
