The length of the vector pointer cones. The parameter can be interpreted in different ways: It can be meant as absolute length or relative to the radius. The used interpretation is decided by the global setting coneLength_interpretation_forStraightVectors.
float
enlargeSmallTextToThisMinTextSize
The normal behaviour of text is that it scales with the line lenght. Though depending on the situation the line may get very small, up until the text is not readable anymore. This parameter sets a limit for the minimum text size. The text carrying line may get shorter and shorter but the text can stay visible.
float
durationInSec
The duration in seconds how long the drawn thing stays visible. The default value of 0 means that it stays only during the current Update frame. Instead of using this parameter you can also overwrite him with a global setting so you don't always have to supply all other preceding function parameters till you reach this late parameter.
bool
hiddenByNearerObjects
This specifies if the drawn thing will get hidden if other geometry is in front of it or if it shines through. It is the same as the depthTest parameter of Unitys Debug.DrawLine(). Not all drawing methods support toggling this in the same way. For some methods the lines are fully hidden, for others the hidden lines shimmer through. Instead of using this parameter you can also overwrite him with a global setting so you don't always have to supply all other preceding function parameters till you reach this late parameter.
