All work done at Piranha Bar.

The following is a breakdown of my role in each clip:

1. Tayto: The Man Behind the Jacket. Modelling and shading.
2. PTSB: Saving and Investing for Life. Modelling, rigging, shading and animation.
3. VHI: Margaret. Modelling, rigging, animation; vehicles, giraffe, birds.
   
4. Nestle Kids Cereal. Modelling, rigging, shading and animation.
   
5. Galaxy Bubbles. Modelling, shading, particles and animation.
6. RTE Idents: Bubbles. Modelling, shading, particles and animation.
7. RTE Idents: Movies. Modelling, shading, particles and animation.
8. RTE Idents: Washing Line. Modelling, shading, particles and animation.
9. Rice Krispie Squares: Western. Modelling and shading; buildings, vehicles, props and plants.

All these projects were worked on as part of the graphics team at PB and I’m very grateful to all of them for their help and support over the past couple of years, I learned a bucket load. Right, onwards and upwards as they say…

Open up a new scene, make sure you have the Model menu open (press 1) and start yourself off with a grid, this will be our page.

• Primitive > Polygon Mesh > Grid
• Length U = 9, Length V = 10
• Subdivisions U = 25, Subdivisions V = 2.

To ensure everything matches up nicely we’re extracting our deformer curve from the mesh itself

• select the central edges running in X

From the Create menu

• Curve > Extract From Edges
• Subdivision = 0

With this new curve still selected, again from the Create menu

• Curve > Fit On Curve
• Subdivision = 1
• Inputs > Delete

So what we’ve just done here is made a curve that matches up with our geometry, then, based on that one, a more simplified, second curve to use as our deformer. Give your curve and mesh some new names, I’m going with  DeformerCrv and Page respectively. Now to setup the deformation,

• Select Page

In the Modify menu

• Deform > by Curve
• Select DeformerCrv

In the Curve Deform menu that opens

• Axis = X
• Translation Along Curve = 4.5
• Constraint > Constrain To Deformer > On

If you now move any of the points on DeformerCrv you should see the Page mesh deforming to match

This is all well and good, but we can’t keyframe these points, instead we have to setup up some clusters. Undo any translations you may have just made to the points on DeformerCrv so our page is nice and flat again.

• Select DeformerCrv
• Press T to see its points
• Select DeformerCrv.Point 1 (it should be second from the left)
• Edit > Create Cluster with Center
• Repeat for points 2 and LAST

You should now have a curve with three nulls along its length, each of these acts as a kind of intermediary allowing us to keyframe the translation of individual points on our curve.

We’ll now use circular curves to limit the page’s  motion and to use as simple controls.

• Primitive > Curve > Circle
• Repeat 4 times
• Give the circles Radii of 9, 6, 3 and 1 respectively
• Snap each to DeformerCrv.Point 0
• From smallest to largest name the circles: Turn, Inner, Mid and Outer

You will notice that three of the circles intersect our cluster nulls

• Constrain > Parent each circle over its corresponding null
• Constrain > Parent Turn over Inner, Mid and Outer
• Select Turn, DeformerCrv and Page
• Edit > Model > New Model

Name the new model Page_1, your hierarchy should look like this:

For ease of use later on we’ll adjust this model’s centre point

• Select Page_1
• Constrain > ChldComp = On
• Center (from the Select menu)
  
• Snap the centre point to DeformerCrv.Point 0

At this stage it’s also  a good idea to zero out any transforms so select everything (easiest way is to make sure you’re in Wireframe mode  in your viewport and drag select)

• Transform > Set Neutral Pose

That’s us done, rotate the circles to control the page turn, Turn adjusts the overall page rotation while the others define the shape.

Here’s a little test animation I did using this setup, I just duplicated and offset the Page_1 model to make a very simple book.

Again, nothing overly advanced here but I’ve found this method useful in all sorts of situations where I’ve needed to control the shape of a curve and haven’t wanted to use shape animation or a bone setup. Hope someone finds it helpful. Crits and comments welcome.
