There are a few ways you can do this.
The first thing we have to establish is that the objects are to scale.
When you create your ShapeKeys. The values for morphing are 0 to 1. You need a way for the user to input a value representative of your scale and then morph the object.
For the sake of simplicity… let’s take the default cube that has a height dimension of 2 units in the Z axis. If the cube is duplicated and moved to the right off of the world origin so that it does not overlap the first cube. We now have two cubes. Grabbing the vertices of the second cube we move them in the z direction 4 units. This makes the overall length of the cube 6 units.
We create the shape keys on the first cube. So now when the first cube shape key Values are at 0 the cube height is 2 and when the shapekey values are 1 the cube height is 6.
Export this to the App Manager for a project of your naming.
Now there are a lot of ways to create the HTML but for this example…I am keeping it simple and just using basic puzzles.
The first thing you need is a set of puzzles stored in your Puzzle Library in the App Manager. Its called Map Range. You can access it in the App Manager in the small icons under the puzzle list….looks like a small book (bottom left).
You will then need to create an action that will allow input, map the range and morph the cube. See attached image.
Thats it really.
Whether its 2 feet, 2 inches, 2mm…doesnt matter….because its scaled the units are not important but should be displayed.
good luck.
