Summary
Public fields |
|
|---|---|
static final @NonNull PolarTargetNode.PolarTarget |
Adds the vector to the brush tip's absolute x/y position in stroke space, where the angle input is measured in radians and the magnitude input is measured in units equal to the brush size. |
static final @NonNull PolarTargetNode.PolarTarget |
Adds the vector to the brush tip's forward/lateral position relative to the current direction of input travel, where the angle input is measured in radians and the magnitude input is measured in units equal to the brush size. |

POSITION_OFFSET_ABSOLUTE_IN_RADIANS_AND_MULTIPLES_OF_BRUSH_SIZE
public static final @NonNull PolarTargetNode.PolarTarget POSITION_OFFSET_ABSOLUTE_IN_RADIANS_AND_MULTIPLES_OF_BRUSH_SIZE
Adds the vector to the brush tip's absolute x/y position in stroke space, where the angle input is measured in radians and the magnitude input is measured in units equal to the brush size. An angle of zero indicates an offset in the direction of the positive X-axis in stroke space; an angle of π/2 indicates the direction of the positive Y-axis in stroke space.
POSITION_OFFSET_RELATIVE_IN_RADIANS_AND_MULTIPLES_OF_BRUSH_SIZE
public static final @NonNull PolarTargetNode.PolarTarget POSITION_OFFSET_RELATIVE_IN_RADIANS_AND_MULTIPLES_OF_BRUSH_SIZE
Adds the vector to the brush tip's forward/lateral position relative to the current direction of input travel, where the angle input is measured in radians and the magnitude input is measured in units equal to the brush size. An angle of zero indicates a forward offset in the current direction of input travel, while an angle of π indicates a backwards offset. Meanwhile, if the X- and Y-axes of stroke space were rotated so that the positive X-axis points in the direction of stroke travel, then an angle of π/2 would indicate a lateral offset towards the positive Y-axis, and an angle of -π/2 would indicate a lateral offset towards the negative Y-axis.
