"Fe O" frames and Misc solid texture pics
MENZIES(C)MONTREAL
COPYRIGHT PROTECTED 1989
**************************************************************************
Included in this file:
1.... Frames from a 1 min ray-traced animation called "Fe_O";
Software: TurboSilver 3.0 & Terrain Generator (Impulse Inc)
Frame01: Looking at a flat landscape through a wave.
Landscape is refracted into fractals and
changes as wave moves. White specularity is
from light source. Camera moves through water.
Frame02: Following behind bird. Bird moves dynamically,
(wings flap and change shape smoothly while the
bird moves across landscape. Bird also rotates
on its own axis).
Frame03: Same but camera is involved more in an erratic
chase of bird.
Frameo4: same as 03.
Frame05: Camera loses bird, and backs out of the hot, dry
environment, breaking the surface of water as it
goes out.(get it)
2.... Miscellaneous solid modelled and ray-traced pics.
Software: TurboSilver_SV (Impulse Inc)
These are just my first couple of experiments with the new SV so
there's no storyboard....they're just little still lifes.
All of the pics in this group, made with SV, use solid (mathematical)
textures only. There are 8 of these new textures (or shaders) in the
new TurboSilver SV. Impulse has also generously (as usual) provided
a "texture kit" containing the programming routines for creating our
own indivdual textures. Creating new textures requires C programming
knowledge. Mathematical textures are verstile (user set parameters),
can have a realistic and natural appearence, can be animated, do not
have the problems that IFF brush maps have like distortion and pixel
magnification, and can be rendered very quickly in solid model. The
SV_solid textures_24bit_VD1(Impulse's framebuffer) combo gave me an
`AMAZING' image on a 26in monitor whereas the regular IFF mapped HAM
mode pics just fell apart.
Most of the `stones' in these pics were given an angular texture
along the six axis (-/+ XYZ) blending several colors together.
The most obvious effect would be rainbow colors but it also solves
the problem of subtle changes of colors in natural objects.
One object has a wood texture where the ringing can be relocated by
relocating the objects axis. Colors, spacing, disturbance(noise), and
ring size are user defined (on the fly!)
There's a sphere with a transparent rippled texture on the top half,
here you easily see the 3D-bumping being hit by the light sources.
The bottom halve was given a grid texture. The `mesh' was given a size
and the area left over was made transparent. Note that 2 pics seem to
be the same. One is ray-traced,the other is solid modelled. The
differences are in reflection,refraction and shadows but not in image
quality or anti-aliasing.(And FAST. I predict between 4-10min on an
030/82/30mhz machine)
* Anyone out there with C knowledge who would like to work together with
me to write and design interesting (weird) and problem solving new
solid textures please contact me. What can we get from this? Well
personal satisfaction for one, put them up on the PD so everyone can
use them, maybe put them on a data disk, work on an animation that we
could go to Siggraph with, but whatever we do I'm sure we can help
make the Amiga a more viable professional 3Dgraphic/animation machine.
