calculatePixelsPerUnit(
canvasHeight,verticalWorldUnits):number
Defined in: rendering/utilities/calculate-pixels-per-unit.ts:10

The render destination's height, in pixels.
verticalWorldUnits
number
The total world-space height the camera should show.
Returns
number
The number of pixels one world unit occupies vertically.
