This 24bit image was created entirely with Octree's Caligari-Broadcast2.1
(texture maps with DCTV) and were originally rendered at 3300x2200 1:1 with
a RCS Fusion40 accelerated A2000/37meg machine then sent to a CI-5000 film
recorder and finally directly printed at 14"x20". The scene contained
aproximently 150,000 polys due to the number objects and their fairly
high level of refinement. The rendering in this file is a scaled down
version (768x482) of the original file.

For those who are further interested there are a couple of areas that they
might want to note:

First, almost 95% of the modelling was entirely done with the new FFD
lattices and auto subdivision/smoothing routines of Caligari-Broadcast. The
remaining 5%+/- of the modelling actually involved editing points. This
approach allows for very simple (light) primitives (everything started as
a either a 32 section sphere, a 10 section cone, or a 10 section cylinder)
to be molded into complex (heavy) shapes by manipulating the control points
on the encompassing lattice and thereby transforming the whole/part of the
object's polygon mesh (similar to working with clay). Drastic angles are
automatically subdivided and smoothed (blended) into the main body . This
method also allows for a great amount of flexibility with regards the
objects shape and variations of that shape.

Secondly, all the objects are 3D objects including the hairy "burrs". In
this example, alternate vertices on a sphere were selected and scaled. The
scaled points formed spikes that automatically subdivided and smoothed back
into the main body of the sphere. To this point I had a fairly regular
looking spiked sphere. I then applied an FFD lattice to the object as a
whole and by manipulating control points on the lattice (which are mapped
to areas of the underlying mesh), I was able to move different areas of the
"hairs" in different directions in real-time while observing every movement
of the mesh in full wireframe within a perspective view. Again, the auto
subdiv/smoothing went to work and curved the hairs in the direction of the
transform. At any time or for the purpose of making different versions, I
can re-apply a lattice and modify the object further.

Thirdly, one will notice that all the objects are UV mapped and all the
textures (often repeating) follow the shape without the usual distortions
that one's accustomed to with the regular spherical, cylindrical and planer
projection map techniques. Caligari also has the ability to use projection
maps but I find those methods inferior for this type of object building.

And lastly, almost all the objects were shaded with the Caligari gouraud
shader. Phong shaders with zero specularity setting would have been a
viable alternative however the gouraud shader gave a slight edge in quality.

This work was made possible with the assistance of Octree Software and
RCS Management accelerators.
