IMAGE DESCRIPTION:
In 1666 the Great Fire of London started in a bakers shop in Pudding Lane.
The fire was the biggest single calamity in the history of the city. It had
destroyed 13,200 houses, 87 parish churches, 6 chapels, 44 Company Halls, the
Royal Exchange, the Custom House, St Paul's Cathedral, the Guildhall, the
Bridewell and other City prisons,the Session House, four bridges across the
Thames and Fleet rivers and three city gates. Surprisingly, only 3 people died
in the blaze.
DESCRIPTION OF HOW THIS IMAGE WAS CREATED:
A rough layout was made with square blocks for the buildings, standard poser
figures for the people and a light in a sphere for the fire. This made an
abstract picture which in some ways I prefer. Anyway, the buildings were
detailed using csg and boxes.
I thought I'd do the same with the people. Bah. I tried exporting the figures
from Poser as a DXF file, then importing them into Amapi to draw some clothes
on them. Poser 1 doesn't like the DXF format. There were big holes in the
image, in particular the heads got completely mashed.
I spent a lot of time trying to convert across with little success. I then
thought I'd use a mesh from 3D cafe (http://www.3dcafe.com). Got some faces,
now we just have the problem of scale - poser file is about 1 unit high, the 3d
meshes are approx 100000 units wide. Amapi doesn't let you scale things too
small, although it will read in meshes with fractional points.
In the end I gave up, and created the whole of the figures using spatch.
To reduce parsing times, I exported from spatch as a DXF instead of as a pov
file (which uses bi-cubics). This was then taken into Amapi and exported from
there as a POV file. The advantage of doing this instead of using crossroads is
that Amapi uses smooth triangles which makes the image look a lot better.
