pure virtual

Computes parameters such as joint limit local rotations to give the desired initial joint limit orientation.

Parameters

jointLimitTypeId	The type ID used to identify the particular kind of joint limit configuration to be created.
parentWorldRotation	The rotation in world space of the parent world body associated with the joint.
childWorldRotation	The rotation in world space of the child world body associated with the joint.
axis	Axis used to define the centre for limiting angular degrees of freedom.
exampleLocalRotations	A vector (which may be empty) containing example valid rotations in the local space of the child world body relative to the parent world body, which may optionally be used to help estimate the extents of the joint limit.

pure virtual

Generates joint limit visualization data in appropriate format to pass to DebugDisplayRequests draw functions.

Parameters

	configuration	The joint configuration to generate visualization data for.
	parentRotation	The rotation of the joint's parent body (in the same frame as childRotation).
	childRotation	The rotation of the joint's child body (in the same frame as parentRotation).
	scale	Scale factor for the output display data.
	angularSubdivisions	Level of detail in the angular direction (may be clamped in the implementation).
	radialSubdivisions	Level of detail in the radial direction (may be clamped in the implementation).
[out]	vertexBufferOut	Used with indexBufferOut to define triangles to be displayed.
[out]	indexBufferOut	Used with vertexBufferOut to define triangles to be displayed.
[out]	lineBufferOut	Used to define lines to be displayed.
[out]	lineValidityBufferOut	Whether each line in the line buffer is part of a valid or violated limit.

virtual AZStd::optional< const AZ::TypeId > AzPhysics::JointHelpersInterface::GetSupportedJointTypeId ( JointType typeEnum ) const

pure virtual

Returns a TypeID if the request joint type is supported. If the Physics backend supports this joint type JointHelpersInterface::GetSupportedJointTypeId will return a AZ::TypeId.
