Field Summary

Fields

Modifier and Type	Field and Description
float	feather_PX The thickness of the feather region, across which alpha fades to transparent.
LineJoinType	joinType How to join connected line segments.
float	miterLimit To keep miters from growing out of control for very sharp angles, miter joins are only used when:
float[]	rgba The color used for the most opaque parts of the line.
boolean	stippleEnable Line rendering is likely to be faster with stippling disabled.
int	stipplePattern Least significant bit is drawn at the start of the line.
float	stippleScale The number of pixels, along the length of the line, covered by one bit of stipplePattern.
float	thickness_PX The thickness of the ideal bounds of the line.

Field Detail

thickness_PX

public float thickness_PX

The thickness of the ideal bounds of the line. Feathering will encroach into these bounds, by half of feather_PX.

feather_PX

public float feather_PX

The thickness of the feather region, across which alpha fades to transparent. Half the feather thickness (the more opaque half) lies inside the ideal bounds of the line, and half (the more transparent half) lies outside.

For feathering to work, GL.GL_BLEND must be enabled.

Line rendering is likely to be faster with feather set to zero.

joinType

public LineJoinType joinType

How to join connected line segments. Defaults to NONE, which gives appearance and performance similar to familiar GL line drawing. Other join types may look nicer, but are more computationally expensive to render.

Line rendering is likely to be faster with a join-type of NONE.

miterLimit

public float miterLimit

To keep miters from growing out of control for very sharp angles, miter joins are only used when:

miterLength <= miterLimit * lineThickness

where miterLength is the distance from the outer tip of the miter to its inner corner.

Otherwise, a bevel join is used instead.

Has no effect unless joinType is LineJoinType.JOIN_MITER.

rgba

public float[] rgba

The color used for the most opaque parts of the line. Due to feathering and/or stippling, some parts of the line may have their alpha values scaled down, so that they become more transparent.

stippleEnable

public boolean stippleEnable

Line rendering is likely to be faster with stippling disabled.

stippleScale

public float stippleScale

The number of pixels, along the length of the line, covered by one bit of stipplePattern.

stipplePattern

public int stipplePattern

Least significant bit is drawn at the start of the line. Despite the "int" type, only the bottom 16 bits are used. 1 = opaque, 0 = transparent.
