PointOptions

PointOptions

This node modifies the appearance of point geometries.

If inserted before a Random Points Node, this node changes the way the individual points are rendered (see ​MSDN: Point Sprites for detailed information). The graphics card renders a point as a 2D, screen-aligned rectangle. By default, the rectangle does not have any texture coordinates but by enabling Sprites, each rectangle is assigned U/V-coordinates such that it can be textured (using a Texture Node).

There are two ways to specify the render size of a point. If ScaleEnabled is inactive, the Size property specifies how many pixels a point is wide and high, independent from its position. By activating ScaleEnabled, the size is computed dependent on the distance to the camera using the Linear, Cubic and Quadric properties (see ​MSDN: Point Sprites for detailed information). Min and Max can be used to clip the actual size used during rendering to the interval between those values.
