2. Operation

2.1 The route

A route, e.g. the course followed by a stretch

of road, is dened by positioning various way-

points and then by tracing out (drawing) a line

over a variable period of time. The starting,

nishing and key points can be specially em-

phasized and you can inuence the way the line

develops.

A route comprises several elements that are

displayed and listed below:

(1) Line

The line can be displayed in various ways and

the following line properties are available:

• Various line thicknesses

• Various colors (invisible when alpha = 0)

• Various line patterns

For certain parts of the route, you can make the

line appear angular (e.g. for roads) or curved

(e.g. for air routes).

(2) Way points

Way points are used to trace out the course that

the route takes. They are only visible during edit-

ing but not in the nal results.

(3) Key points

You can place key points along a route. You

can then label them in various ways, though

generally you use the same type of label for all

key points so that you can easily make global

changes. You can also dene pauses in the

line‘s growth at key points. These can be simple

pauses or interruptions to the generated scene.

In the second case, you can interrupt the video

footage to display how the various route sec-

tions develop throughout the lm.

(4) Starting point

The starting point for drawing the route is the

origin of the line. Other than that, the starting

point provides you with the same options as a

key point.

(5) Head

You can optionally provide the head (leading

end) of the growing line with an additional label

that moves as the line grows (e.g. an arrowhead,

hand, car, etc.). An object moving with the head

can be made to automatically change direction

to point in the direction that the line is develop-

ing.

(6) Finishing point

The nishing point represents the journey’s

destination and provides the same options as a

key point.

Various symbols positioned inside the colored

points on the route are used to represent the

above mentioned points. These symbols are

shown in the table below.

Starting and nishing points

If you have not done any editing yet, the starting

and nishing points that are connected by a line

are generally displayed in a position outside the

menu bar area. The starting and nishing points

are clearly marked as such and can be reposi-

tioned and edited like any other point. However,

you cannot delete them.
