Ultimate unwrap 3d demonstration
The involute of a logarithmic spiral is not a logarithmic spiral, except in the limit, when the starting point is the limit point at the center of the spiral, which is not the case in this Demonstration. The involutes of the cycloid and cardioid are an equal cycloid and similar cardioid, respectively, given that the starting point in both cases is at a vertex.
A developable helicoid should not be confused with a right or rectangular helicoid, which is the surface swept out by a straight line meeting a helix to its axis orthogonally at both ends. 1 Unfold3D Core inside Maya 2015 Unfold3D plugin is now included in standard into Maya 2015 and Maya LT.

To select a part of the model in the 3D window, navigate to get a clear view of all the vertices or facets you want to select. The tangent developable of a circular helix is also called a developable helicoid. Formats Ultimate Unwrap 3D supports over 100 file formats, including FBX, DAE, ASE, DXF, LWO, OBJ, and DirectX. To navigate in one of the 3D windows, hold down the Shift key and the Left Mouse Button (LMB) to zoom in or out, CTRL and LMB to dolly left or right and up or down, and LMB alone to rotate your viewpoint about the model. The slider moves the tangent, normal, and osculating plane of the seam and illustrates how the tangent developable envelopes the osculating planes. A tangent developable of a curve is the envelope of its osculating planes. The involute is the intersection of the tangent developable with the base plane. The surface is called the tangent developable. Snapshots 4, 5, and 6: Another view of the involute of the base is obtained by considering the surface swept out by the movement of the tangent along the seam.
The intersection of the tangent line of the seam and the plane containing the base traces the involute of the base curve. We call the seam helical because, like the helix, its height above the base is proportional to the distance traversed along the base.
Snapshots 1, 2, and 3: The slider unwraps the right cylinder based on the selected plane curve and along a helical seam of slope 1/2 inscribed in the cylinder.
