Floater.x3d (X3dToXhtml listing)

Event Graph ROUTE Table entries with 2 ROUTE connections total, showing X3D event-model relationships for this scene.

Each row shows an event cascade that may occur during a single timestamp interval between frame renderings, as part of the X3D execution model.

Clock
TimeSensor
fraction_changed
SFFloat

→
ROUTE
event to
(1)

Mover
PositionInterpolator
set_fraction
SFFloat

then

Mover
PositionInterpolator
value_changed
SFVec3f

→
ROUTE
event to
(2)

Movee
Transform
set_translation
SFVec3f

ProtoInstance
Pad

No ROUTE connection found for output events from this node.
This ProtoInstance contains SFNode/MFNode fieldValue declarations with
direct access to other nodes, and thus has potential to produce run-time animation.

25	<Scene>
26	<!-- Complexity is created from simplicity via two tricks: -->
27	<!-- 1. Create a set of simple shapes, then repeat the same shapes several times. In this case, there are only 7 original pads moving left and right. Those 7 are repeated again, but turned around the Y axis so that they slide front to back. The same 7 are repeated again, but rotated around the Z axis so that they slide up and down. The effect is one of a complex bunch of moving shapes when in reality there are only 7. -->
28	<!-- 2. Give each moving shape a slightly different cycle interval for its animation. This makes all the movement out of sync, which again creates the appearance of complexity. -->
29	<!-- A PROTO is used to create a new Pad node that incorporates a box shape, a time sensor, a position interpolator, and routes to connect them together. Fields to the Pad node control the initial placement of the pad, and it's animation cycle interval. -->
30	<!-- Add textures. Particularly try adding a texture with a transparency (alpha) channel. Using transparency textures you can add stripes, checks, or whatever to the pads. One approach that looks interesting is to add a cloud texture, but make the sky behind the clouds transparent in the texture. When mapped, this creates a blobby indistinct shape on each pad. -->
31	<!-- Add a Transform node around the entire group of pads, then use an OrientationInterpolator and TimeSensor to slowly spin the world. Remembering the complexity tricks above, you can create a complex tumble by using three nested Transform nodes (X, Y, and Z), each with its own OrientationInterpolator and TimeSensor. Give the three TimeSensors slightly different cycleInterval values (such as 5.0, 7.0, and 11.0). Prime numbers are good choices. Since the cycle times are different for the three spins, they don't sync up, and it looks like a chaotic tumble. -->
