Link Object

A link object points to a geometric object. It can be used where a geometric object would be evaluated.

The first link tutorial shows you how to evaluate a curve object through a link.

Tutorial level: Beginner

Example project: 'tutorprojects/modeling/link/linkpath'

1. Create a curve using the NURBS/Curve tool.

The Link tool selected

2. Select the curve. Go to the Creation tab of the toolbar and apply the Link tool. new object called 'link (nurbs3)' appears in the object hierarchy.

3. Create an analytic sphere near the first point of the curve.

4. Select the sphere and the link object in that order.

5. Go to the Lattice Mapping tab of the toolbar and activate the Path tool.

Click the Accept button.

6. Click the Play button on the Animation window to see how the sphere follows the curve.

Using a link object with particles

Tutorial level: Beginner/Intermediate

Example project: 'tutorprojects/modeling/link/linkparticle'

1. Go to the Creation tab and activate the Particle tool. Create a cloud of 1D particles and accept the tool.

2. Select the particle object. Open the Property window. Select the Spec tab, then the Constructor sub tab. Set the Constructor gadget to Distribute over Surface.

3. Create an analytic sphere.

4. Select the sphere. Apply the Link tool.

5. Drag & drop the link object inside the particle level object. The object hierarchy should be as in the adjacent image.

The particles are now distributed over the sphere's surface.

Using a link object with fluid dynamics

Tutorial level: Intermediate

Example project: 'tutorprojects/modeling/link/linkfan'

1. Go to the Creation tab and activate the Particle tool. Create a cloud of 1D particles and accept the tool.

2. Select the particle object. Open the Property window. Select the Spec tab, then the Constructor sub tab. Set the Constructor gadget to Emitter.

3. Select the Phys tab and set the Mass gadget (inside the General frame) to 0.01.

4. Select the Sim tab and set the Fluid Dynamics gadget to Affected.

5. Create an analytic sphere.

6. Select the sphere. Apply the Link tool.

7. Drag & drop the link object inside the particle level object.

The object hierarchy

8. Create a Fan object pointing at the sphere (The Fan tool is in the Simulation tab of the toolbar). The object hierarchy is shown in the adjacent image.

9. Click the Play button on the Animation window to see how the particles are emitted from the sphere and blown away by the fan.
