Detailed Description

struct A3DGraphDottingPatternData

Dotting fill pattern descriptor.

Drawing a shape can be done by filling its drawn face using a dotted pattern (alternative ways could be using a texture or a solid color, for example). This technique is generally associated with halftone pattern, which consists in simulating continuous tone through dots.

Version: 2.0

A3DGraphDottingPatternData is one of the four fill pattern provided by HOOPS. It is associated to the kA3DTypeGraphDottingPattern entity type. The other available fill patterns are A3DGraphHatchingPatternData, A3DGraphSolidPatternData and A3DGraphVPicturePatternData.

Pattern description: This descriptor is used to represent an axis-aligned grid of dots, each of them being spaced by a distance of m_dPitch, horizontally and vertically. When m_bZigZag is true, dots are appear within a staggered layout, where every other line is horizontaly shifted by half m_dPitch.
Pattern layers: Implementations can express complex patterns by chaining them in order, using the m_uiNextPatternIndex field.
