![]() Fortunately, we can animate this!īring up your right panel with the N key (if you haven’t already) and look at the cylinder’s Z size. Remember back to my comments about the radius of the circle initially, we left it set at one, so now we need to set the size of the cylinder to match the circumference of the circle. This problem (the cylinder not going around the whole circle,) is exactly what we are going to use to properly animate the ring as it goes around the track. (if you haven’t yet, change the shading on the cylinder to smooth.) But there’s a problem. Tab back out of edit mode and you should see a difference in the way it curves around the circle. Left click then right click to accept and place evenly. You can look at the bottom left to see how many cuts you are up to. For this example I’m going with 63 loops (creating 64 vertical pieces.) Tab in to edit mode, mouse over the center of the cylinder and then push Ctrl+R and scroll up on the mouse wheel. Create loops in the cylinder until you are happy with how many you have for the resolution. ![]() We fix the deforming by giving it more geometry to work with. You’ll notice That our cylinder is on the circle the way we want it, but isn’t deforming and isn’t covering the whole thing. To illustrate what I mean, go ahead and add a modifier to your cylinder so that it runs the course of the circle: Curve mod, Object is the BezierCurve, Deformation Axis is Y. This is the point where we’ll pick the resolution of our curve. Select all the verts (Ax2) and then bridge the loops (Ctrl+E, L). In edit mode, duplicate the vertices (Shift+D and right click to commit) then grab and move them up 1 unit on the z axis (G, Z, numpad 1 and Enter to commit.) Now we have two circles of vertices, 1 Blender Unit away from each other. The settings I’m using are for 16 verts and a radius of 0.1 (I want this cylinder to be very thin and long.) You won’t be able to see the circle, because it’s flat from front view, so alter your view slightly and then tab into edit mode. Now, add a basic circle mesh (we’re going to make it cylinder in a moment): (Shift+A Mesh->Circle) ![]() For now, leave it at 1, but just keep it in mind for the future. There’s a small point to be made here about the radius of the circle, which I’ll come back to in a moment. Make sure you tick the ‘Align to View’ box if you want easy numbers as we go forward. So, clear a fresh scene and we’ll get started.įirst step is to go to front ortho view and then add a circle curve: (Shift+A Curve->Circle) So, Alex Otten posed a question about this animated version of the Imgur logo. I decided to try my hand at it using curves to deform a cylinder.
