Detailed Description

SoPolylineResamplerApproximation2d polyline approximation.

This engine resamples an input 2D polyline using either a linear, cubic or a cubic with Paul Breeuwsma coefficients (Catmull-Rom spline) interpolation.

The spacing between new points is defined by the spacing parameter.

Member Data Documentation

SoMFVec2f SoPolylineResamplerApproximation2d::inPolyline

Input polyline to resample.

SoSFEnum SoPolylineResamplerApproximation2d::interpolationMode

Interpolation mode.

Use enum InterpolationMode. Default is LINEAR.

SoImageVizEngineMFieldOutput< SoMFVec2f, const SbVec2f*> SoPolylineResamplerApproximation2d::outPolyline

Output resampled polyline.

SoSFDouble SoPolylineResamplerApproximation2d::spacing

Spacing between nodes in extrusion.

This spacing is expressed in world coordinates. Default is 1.
