    • CURRENT_HIGHLIGHT

      static final int CURRENT_HIGHLIGHT
      Passed as highlight-parameter to the draw-methods of this interface if the current highlight has to be used instead of the parameter.

      GraphState getRenderGraphState()

    • getPool

      Pool getPool()

    • getFontMetrics

      FontMetrics getFontMetrics(Font font)

    • getCurrentHighlight

      int getCurrentHighlight()

    • estimateScaleAt

      float estimateScaleAt(Tuple3f point)

    • getCurrentShader

      Shader getCurrentShader()

    • drawPoint

      void drawPoint(Tuple3f location, int pixelSize, Tuple3f color, int highlight, Matrix4d t)

    • drawPointCloud

      void drawPointCloud(float[] locations, float pointSize, Tuple3f color, int highlight, Matrix4d t)
      Draw a set of points. The array locations contains a sequence of points given as triples of floats for x, y and z position of each point. If the same reference for the array location is passed in the implementation might assume that the contents of the array are the same as well. This is necessary for GLDisplay, for instance, to ensure a performant implementation. The class PointCloud ensures that this is the case.
      Parameters:
      locations - array containing a sequence (x,y,z) of points
      pointSize - size of the point on screen
      color - color of the point
      highlight -
      t - transformation of the point cloud
