    (
        const FViewCameraState & CameraState,
        const FFrame3f & LocalFrame,

Remarks

Draw a basic 2D grid with a given number of lines that covers roughly a constant area of the screen

Parameters

Parameter	Description
CameraState	camera state, required to size grid appropriately
LocalFrame	Pre-transform frame of grid (grid lies in XY plane).
GridLines	number of grid lines. If odd, there is a center-line, if even then frame center is at center of a grid square
VisualAngleSpan	visual angle that grid should cover (in degrees, relative to default 90-degree FOV)
LineWidth	thickness of the lines in screen space
Color	color of the lines
DepthPriority	drawing depth priority
PDI	drawing interface
Transform	transform applied to LocalFrame. Pass as Identity() if you have world frame.
