On #43310, class reference was automatically updated from source, causing xml documentation to disagree with parameter naming description on Plane.intersects_segment(). Weirdly, it also changed the parameter for Plane.is_point_over() from point to plane, when only the first has sense (and it is defined on math.Plane as "const Vector3 &p_point"). Manual mistake? * Update begin/end to from/to on Plane.intersects_segment(...) docs description to match source * Update Plane bindings to use points instread of plane for is_point_over(...) * Change Plane.is_point_over(plane) to Plane.is_point_over(point) AND its description on docs Fixes godotengine/godot-docs#5976

Plane represents a normalized plane equation. Basically, "normal" is the normal of the plane (a,b,c normalized), and "d" is the distance from the origin to the plane (in the direction of "normal"). "Over" or "Above" the plane is considered the side of the plane towards where the normal is pointing.

Returns [code]true[/code] if the planes are exactly equal.

<description>

Returns the same value as if the [code]+[/code] was not there. Unary [code]+[/code] does nothing, but sometimes it can make your code more readable.

<operator name="operator unary-">

<return type="Plane" />
|
|
<description>
|
|
Returns the negative value of the [Plane]. This is the same as writing [code]Plane(-p.normal, -p.d)[/code]. This operation flips the direction of the normal vector and also flips the distance value, resulting in a Plane that is in the same place, but facing the opposite direction.
