                           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

t - transformation of the point cloud
