Tooltip

VRML PROTO (based on IndexedFaceSet) that generates a rounded rectangle with a tip that visually links to an arbitrary 3D position.

The side where the tip is attached to the rectangle is automatically deduced from the relative position of the target.

EXTERNPROTO Tooltip [
    exposedField  SFVec3f  center

    exposedField  SFFloat  radius

] "proto.Tooltip.wrl#Tooltip"

Property center

3D position of the center of the rounded rectangle.

Definition:

• Field Type: exposedField
• Data Type: SFVec3f
• Default Value: 0 0 0

Property tip

3D position of the tip of the triangle attached outside the rounded rectangle.

Definition:

• Field Type: exposedField
• Data Type: SFVec3f
• Default Value: 0 0 0

Property size

Width & height of the inner area of the rounded rectangle.

You could use MonospaceText.bboxSize
to fit a tooltip around an arbitrary text.

Definition:

• Field Type: exposedField
• Data Type: SFVec3f
• Default Value: 2 2

Property radius

Radius of the rounded border of the rectangle.

Definition:

• Field Type: exposedField
• Data Type: SFVec3f
• Default Value: 1

Property solid

Like IndexedFaceSet.solid, renders both sides (FALSE) or only the front side (TRUE).

Definition:

• Field Type: field
• Data Type: SFBool
• Default Value: TRUE
