### ProportionOfScreenHeight

If this unit is used, the point size will be multiplied by the height of the screen.

### ProportionOfScreenWidth

If this unit is used, the point size will be multiplied by the width of the screen.

### ScreenPixels

Point size is measured directly in pixels of the output image, regardless of display DPI.

### World

The world-space units in which model geometry is defined. If this unit is used, points will scale according to distance from the camera under perspective projection.
