Vertigo
revealed
I
have had several enquiries about the construction my Vertigo image that was posted
to the Bryce Forum Gallery. It appears as though hundreds of cylinders
were used in a huge lattice to create the apparent endless depth. In reality
very few real objects were used, the effect is possible due to reflections and
Bryce's perfect mirror materials.
What
follows is a brief rundown of the technique used, it isn't complicated, only
one cube and 12 cylinders are used!
Here is a brief run down of how it was done.
Basically
it relies on Bryce objects being hollow.'Vertigo' started life as a cube or
box object with a highly reflective surface applied. This box then becomes the
boundaries of your 'World'.
The
next step is to move the camera and a couple of light sources to within the
'World'. I've found it best to keep the lights dim otherwise they wash out the
image due to the multiple reflections. Better to have more low intensity lights
than 1 or 2 bright ones. For the structure I took a standard cylinder and stretched
it until it was slightly longer than one edge of the 'World' I then applied
a techy/city type of material to the cylinder.
Then
11 duplicates were made ( 12 edges on a cube ) these were lined up to each edge
of the 'World' in turn such that only a quarter of each cylinder is visible
from inside the World. Due to the internal reflections the viewer is fooled
into seeing whole cylinders. That completes the basic scene, 12 cylinders one
cube + Camera and a few lights. It's then just a matter of positioning the camera
to give a good view of all the reflections along with adjusting the light levels
and careful positioning of the lights.
One
other point, the global sky/sun settings affect the lighting within the 'World'
even though it is effectively a sealed room. Maybe someone with more technical
knowledge of how Bryce works internally could explain that one. Initially I
set the sky/atmosphere to black with a black sun, (Bryce3 users could turn off
the sun of course). You can then tryout different combinations of sun/sky colours
to get some really neat effects.
