<brief_description>
A twist joint between two 3D bodies
</brief_description>
<description>
The joint can rotate the bodies across an axis defined by the local x-axes of the [Joint].
The twist axis is initiated as the x-axis of the [Joint].
Once the Bodies swing, the twist axis is calculated as the middle of the x-axes of the Joint in the local space of the two Bodies.

<brief_description>
The generic 6 degrees of freedom joint can implement a variety of joint-types by locking certain axes' rotation or translation.
</brief_description>
<description>
The first 3 dof axes are linear axes, which represent translation of Bodies, and the latter 3 dof axes represent the angular motion. Each axis can be either locked, or limited.

This is the constant for creating convex polygon shapes. A polygon is defined by a list of points. It can be used for intersections and inside/outside checks. Unlike the method [method CollisionPolygon2D.set_polygon], polygons modified with [method shape_set_data] do not verify that the points supplied form, in fact, a convex polygon.
