Here is how to zoom in and out using script:

scene.camera.zoom = n where, n range is 1.5 to 3000.
1.5 is zoom out max (100 meter scale), and 3000 is zoom in max (0.01 meter scale). Default value is 150.


Have phun!

yeah i was using theat but it was really laggy unfortunatly! thanks though

This is a creative way of making an archimedic spiral. You could try drawing the outline using a box with a tracer and some maths if you want too, given you know the maths behind this spiral and thyme.

Suggestion: Make the scene so it starts all the way zoomed out as opposed to all the way zoomed in.

Details:
I was playing with this and noticed that it generates 6X faster when zoomed all the way out vs. all the way in. My suggestion would be to zoom all the way out (zoom = 0.01) and run the scene until the boxes start to become visible and then stop and save the scene. This way the new scene will appear to generate 15X faster and then the user can zoom in as opposed to zoom out.
