- 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. The petals of the lili were
- originally 32 sectioned spheres and the quasi-morning glorys started as
- a 10 sectioned cone. The thorns were "pulled" points that automatically
- subdivided and were then curved by placing a ffd lattice on each one and
- moving a control point on the lattice. The thorns further subdivided and
- smoothly curved in the direction of the transform all in realtime and
- I was able to see the mesh move in with a full wireframe representation
- in a perspective view.
-
-
- Seconly, 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.
- The map on the lili petals is one complete map that has thin brownish
- lines and dots on the front of the petal (following the shape of the
- petal and yellow with a greenish stripe on the back of the petal.
- Most of the textures in these pictures are 2 or 3 color gradations made
- in dctv-paint.
-
- 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.
