- 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.
