	<brief_description>
		Blends linearly between three [AnimationNode] of any type placed in a 2D space.
	</brief_description>
	<description>
		A resource to add to an [AnimationNodeBlendTree].
		This node allows you to blend linearly between three animations using a [Vector2] weight.
		You can add vertices to the blend space with [method add_blend_point] and automatically triangulate it by setting [member auto_triangles] to [code]true[/code]. Otherwise, use [method add_triangle] and [method remove_triangle] to create up the blend space by hand.

			<description>
				Adds a new point that represents a [code]node[/code] at the position set by [code]pos[/code]. You can insert it at a specific index using the [code]at_index[/code] argument. If you use the default value for [code]at_index[/code], the point is inserted at the end of the blend points array.

			<description>
				Creates a new triangle using three points [code]x[/code], [code]y[/code], and [code]z[/code]. Triangles can overlap. You can insert the triangle at a specific index using the [code]at_index[/code] argument. If you use the default value for [code]at_index[/code], the point is inserted at the end of the blend points array.
