Wheels & Volcanoes
-
This is part IV. of IV. Results of a design seminar on firework architecture at the Bauhaus University Weimar.
I. The Design Seminar and its Results
II. the collaboration of ArchiCAD and F3D
III. F3D as a tool for the reconstruction of historical fireworks
IV. wheels & volcanoes
During the design seminar, the simulation of volcanoes emerged. It is therefore difficult to simulate fountains that increase in intensity over time. Fortunately, Dirk Enders from Pyrooffice could help with a solution.
The following steps are necessary.
1. create a fountain with vdl.
2. Open it in the effects editor.
3. set the trail emit-speed-taper value to 300.
4. save.
A far greater challenge was to create the spinning wheel for the reconstruction of the fireworks of a hundred years ago.
The spinning wheel options in Finale3D do not allow the effects and drivers to be positioned at different distances on a line.
However, it is possible to export and manipulate the spinning wheel as a macro.
Exporting
1. Create a sun with the desired effects.
2. File > Admin > Decompress macros.
3. File > Export Effects…
Manipulate
1. open the saved Wheel CSV in Excel
2. copy the text in the vdl table
3. Manipulate the vdl in the editor of your choice.
4. paste the manipulated vdl back into the table.
How is the vdl structured?

It can be divided into 2 parts. The first part consists of information about the effects of the wheel. The second part contains the movement and position of the effects. Except for the name of the macro, everything in the first part remains unchanged. The second part requires a little more attention.
The most frequently changed parts are pos, pos2 and hpr.
Pos sets the position of the rotation axis. (0 0 2.0 0) H X Y Z. The third value determines the height above the position. I prefer to define the centre of the wheel with a position. Therefore, the value is usually 0 for me.
The second value, pos2, determines the position and the alignment to the rotation axis. (0 0.25 0 0) H X Y Z. This defines the angle of the effect to the tangent of the wheel.
The first number is milliseconds, the second is the axis of rotation around the effect, the third value is the axis of rotation around the tangent of the wheel. And the most important value, the fourth, The rotation and the rotation axis set in pos.
The ##scriptRow package can be multiplied as often as desired and adjusted accordingly. Note that the time in the hpr value refers to the actionTime.
Import
1. insert the manipulated vdl
2. make sure that the macro name has been modified
3. adjust the partNumber
4. save as CSV
5. in F3D Import effects file
6. in Effect Window under Type change to macro.
7. place.
With a little fiddling you can simulate exciting wheels.
