I would like to create a special effect and I was wondering how to approach this.
The effect seems to be quite simple: I would like to animate the drawing of a simple object (e.g. a bar, a line, a tube, a square) as one can see it in various SF films. First a (invicible) pen draws the lines of the floor, then the lines of the walls are drawn, finally the ceiling/top of the bar is drawn.
Additionally the lines are drawn in parallel by more than one (invicible) pen. Cool would also be to have a glowing effect a the point of the pen.
The architecture of the object is known in advance.
To be true I have no good idea how to approach this.
- With scaling I can’t realize the visual effects I want to have.
- One option would be to have something which makes the object partially invisible (like cutting it away) and the “drawing” is making the object visible gradually.
- Manipulating the vertexes of the object?
