Description

Draws a line in 3D space.

This is a rendering function that requires a 3d rendering context.

This means that it will only work in 3d Rendering Hooks.

Arguments

1 Vector startPos
Line start position in world coordinates.
2 Vector endPos
Line end position in world coordinates.
3 table color = Color( 255, 255, 255 )
The color to be used. Uses the Color.
4 boolean writeZ = false
Whether or not to consider the Z buffer. If false, the line will be drawn over everything currently drawn, if true, the line will be drawn with depth considered, as if it were a regular object in 3D space.
Enabling this option will cause the line to ignore the color's alpha.
