ArrowSource

Source (.js)Source (.d.ts)

Introduction

vtkArrowSource was intended to be used as the source for a glyph. The shaft base is always at (0,0,0). The arrow tip is always at (1,0,0). If "Invert" is true, then the ends are flipped i.e. tip is at (0,0,0) while base is at (1, 0, 0). The resolution of the cone and shaft can be set and default to 6. The radius of the cone and shaft can be set and default to 0.03 and 0.1. The length of the tip can also be set, and defaults to 0.35.

Usage

import vtkArrowSource from '@kitware/vtk.js/Filters/Sources/ArrowSource';

const arrow = vtkArrowSource.newInstance({
  tipResolution: 6,
  tipRadius: 0.1,
  tipLength: 0.35,
  shaftResolution: 6,
  shaftRadius: 0.03,
  invert: false,
  direction: [1.0, 0.0, 0.0]});
const polydata = arrow.getOutputData();
