DTD Validation

Usage

Although it is defined as an X3DChildNode it can only appear, apart from prototype definitions, as a child of a RigidBodyCollection or CollisionSensor node.

Children

Children must appear as follows:

1. A single, optional IS.
2. A single, optional node derived from X3DMetadataObject for the metadata field.
3. Any number of nodes, including zero, of the following types:
   1. An appropriately typed Prototype node
   2. CollidableOffset
   3. CollidableShape
   4. CollisionSpace

Attributes

• There are no controls on the acceptable entries for the appliedParameters field.
• There are no limits on the values for the bounce, frictionCoefficients, minBounceSpeed, softnessConstantForceMix, or softnessErrorCorrection fields.

• The containerField attribute has a default value of "collidables".

Attributes

• There are no controls on the acceptable entries for the appliedParameters field.
• The bounce field is checked to ensure that the value is in the range 0 to 1 inclusive.
• There are no limits on the values for the frictionCoefficients field.
• The minBounceSpeed field is checked to ensure that the value is greater than or equal to zero.
• The softnessConstantForceMix field is checked to ensure that the value is in the range 0 to 1 inclusive.
• The softnessErrorCorrection field is checked to ensure that the value is in the range 0 to 1 inclusive.

• The containerField attribute has a default value of "children".
