Interface Arc2D

All Superinterfaces:
X3DGeometryNode, X3DNode
All Known Implementing Classes:
Arc2D
public interface Arc2D extends X3DGeometryNode
Arc2D is a line-based geometry node that defines a linear circular arc with center (0,0) in X-Y plane, with angles measured starting at positive x-axis and sweeping towards positive y-axis.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. X3D node tooltip: [X3DGeometryNode] Arc2D is a line-based geometry node that defines a linear circular arc with center (0,0) in X-Y plane, with angles measured starting at positive x-axis and sweeping towards positive y-axis. Hint: Material emissiveColor in corresponding Appearance is used for rendering lines. Warning: lines are not lit, are not texture-mapped, and do not participate in collision detection. Warning: use a different Material emissiveColor than the Background color, otherwise geometry is invisible. Hint: adding LineProperties to the corresponding Appearance node can modify the rendering style of these lines. Hint: insert a Shape node before adding geometry or Appearance. Warning: requires X3D profile='Full' or else include &lt;component name='Geometry2D' level='2'/&gt; Examples: X3D Example Archives, X3D for Web Authors, Chapter 10 Geometry 2D <a href="https://www.web3d.org/x3d/content/examples/X3dForWebAuthors/Chapter10Geometry2D" target="_blank">https://www.web3d.org/x3d/content/examples/X3dForWebAuthors/Chapter10Geometry2D</a> *

  • Method Details

    • getEndAngle

      float getEndAngle()
      Provide float value unit axis, angle (in radians) within allowed range of (-6.2832,6.2832) from initializeOnly SFFloat field named endAngle.

      Tooltip: [0,2pi] Arc extends from startAngle counterclockwise to endAngle, in radians. Warning: simple-geometry dimensions are initializeOnly and cannot be changed after initial creation, avoiding the need for potentially expensive tessellation at run time. Hint: for size animation, modify the scale of a parent/ancestor Transform node instead. Hint: radian units for angular measure <a href="https://en.wikipedia.org/wiki/Radian" target="_blank">https://en.wikipedia.org/wiki/Radian</a> *
      Returns:
      value of endAngle field
