getRenderGraphState

public GraphState getRenderGraphState()

Specified by:

getRenderGraphState in interface RenderState

getPool

public Pool getPool()

Specified by:

getPool in interface RenderState

getFontMetrics

public FontMetrics getFontMetrics(Font font)

Specified by:

getFontMetrics in interface RenderState

getCurrentHighlight

public int getCurrentHighlight()

Specified by:

getCurrentHighlight in interface RenderState

estimateScaleAt

public float estimateScaleAt(Tuple3f point)

Specified by:

getCurrentShader

public Shader getCurrentShader()

Specified by:

drawPoint

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

Specified by:

drawPoint in interface RenderState

drawPointCloud

public void drawPointCloud(float[] locations,
 float pointSize,
 Tuple3f color,
 int highlight,
 Matrix4d t)

Description copied from interface: RenderState

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.

Specified by:

drawPointCloud in interface RenderState

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
