| This page provides hints and tips for users of the
excellent 3d fractal program, Xenodream. It does not explain where to
find the controls, and assumes that you are familiar with the
interface. It is intended for intermediate level users. |

General Tips
- I very rarely start creating from scratch - it is MUCH
easier to find an interesting shape and modify it!
- Changing holon types is particularly effective with this
technique, often resulting in a completely different appearance.
- I tend to work by building the parameter files for
rendering, then rendering them later. This keeps things moving when I
find a productive file with many interesting variations.
- I keep a text file of things waiting to render on my
desktop, so I don't forget.
- For best results, render big, render overnight!
- Try viewing your object from many angles - interesting ones
are often not the shape you might at first assume, and some have many
different effective viewing angles.
- It can be very effective to move the camera in very close,
and set it to a very wide angle view with fish-eye on. This can
radically transform the view, but be aware that parts closest to the
camera may take a long time to render.
- When saving files, be sure to put your name into the
relevant field! This will help you track which XEP's are your original
work.
Getting a smooth result
- Because of the way Xenodream works, you often find that
images have a rough or jagged appearance, caused by many sudden changes
in colour.
- Become familiar with the surface cleaning tools, these can
be VERY effective in producing a pleasing result.
- Experiment with lighting - this can dramatically affect the
smoothness of your result.
- The most important tip I can give is RENDER
LARGE AND SAMPLE DOWN THE RESULT.
I do this with almost every image I create.
- For example, if you want a wallpaper sized image, try
rendering at 2000x1500, then resample to a smaller size in your
favourite graphics program.
Lighting and surfacing tips
- Create a 'favourites' category, and store all your most
used lighting presets in there. This will make them much easier to find.
- I very much prefer surfaces that emphasise the 3d shape of
the object. For this reason I like to use:
- Reflection, to emphasise the relative position of the
parts.
- Shadows, to emphasise the relative position of the
parts.
- Fog / mist to emphasise how deep in the picture the
parts are.
- Interference colours, to emphasise the slope of the
parts.
- For viewing on a computer screen, try to keep your
brightest light top left of the image - this is the lighting source for
3d controls in Windows, and it will match better done this way.
- When examining the XEP files people share in the mail
groups, don't forget to save any impressing lighting set-ups for future
use.
Export and Render tips.
- It is generally a mistake to try and capture too much
detail when exporting. You will end up with a huge unmanageable polygon
count.
- I generally find a resolution of 300-320 works well for my
preferred shapes.
- The included polygon reduction tool is EXCELLENT and gives
instant visual feedback! Use it!
- I find the best way to get a smooth object out is to reduce
the polygon count in XD as far as possible, then smooth the result in
my 3d rendering program.
- In Lightwave that means using 'NURBS' or the Subdivide
Smooth command.
- I like similar surface effects when rendering as I do
inside XD - Lots of reflection, shadows, and so forth.
- If your graphics program supports it, vary the reflection
with the angle of incidence. Shiny surfaces generally reflect much more
when viewed at a shallow angle.
- Varying the colour with the angle of incidence is also very
effective.
- I have had very pleasing results by placing the object
partially submerged in rippling reflective water.
- Adding strongly geometric elements such as refractive
crystal balls, or chrome hoops can also help emphasize the shapes
strongly
- If your shape has interesting holes in it's structure, you
can make an interesting animation by flying the camera through the
object..
If you want to learn more, I strongly recommend joining one or
both the Xenodream
mailing lists, where you will find many examples of other people work,
and sometimes XEP
files too.
The Xenodream WebRing will also provide
inspiration and resources.
