1. Here
we will model a basic Virus and render it in Lightwave. So fire up the
Modeler and lets make a nifty virus! Start out by making a sphere with
the settings shown in figure 1. A tesselated sphere with two segments
and a radius of 500mm.
|
|
2. Select
all polygons using the 'Lasso' (Bottom bar -> Polygons -> Use right mousebutton).
This step is important, make sure that you have all the polygons selected
before moving further. Then use the 'Bevel' tool (Multiply -> Bevel or
use the hotkey b). Bevel them three times like this.
|
| 3.
Convert these threesided polygons to 'SubPatches' by simply pressing 'Tab'
on your keyboard. Whoa...smooth curves!! Now just apply a surface called
'virus' to it by using the 'Surface' tool (Detail -> Polygons -> Surface
or use the hotkey q). Now save your objects as something fitting, I saved
mine as "cuddlymicrobe.lwo". Now we are done in the Modeler. Close it and
fire up Layout, time for texturing and rendering! |
|
4. Now
we are in Layout. Load in your object and position the camera in a fitting
position, as in figure 3.
|
|
5. Now
lets texture this bastard! Go into the surface editor and lets start with
the basic settings. Start by giving it a colour of full white, RGB 255,255,255.
Lower the 'Diffuse' to 0%, activate 'Smoothing' at the bottom. After that
its time to set up the 'Luminosity' which is the key to getting the Electronic
Microscope effect. Press the little 'T' button next to the 'Luminosity'.
We are gonna make a gradient here. So in the top right, set the 'Layer
Type' to 'Gradient'. You'll see a big white vertical bar appear, this
is our gradient. We are gonna make a smooth transition from black to white.
So click once on the white bar to greate a Key. Then click and hold on
the key you just created and drag it all the way down to the bottom. When
that is done. Change the 'Input Parameter' to 'Incidence Angle'. What
this does, with a black-white gradient is that the more a polygons is
facing AWAY from you, the whiter it becomes. Now we are done here, figure
4.

|
6. Its
too smooth to look good though, lets add a little texture to it with a
bumpmap. In the Surface Editor, click the little 'T' button next to 'Bump'
and lets make a bumpmap. Change the 'Layer Type' to 'Procedural'. Set
the 'Procedural Type' to 'Crumple', the 'Texture Value' to -200, 'Frequencies'
to 20 so we get lots of details. You can leave the rest at their default
values, figure 5.

7.
If we were to render it out now, we would have a 'Virus' image. But there
is still one important thing missing to complete the illusion, the Depth
Of Field. For this we will use the new 'Digital Confusion' plugin that ships
with LightWave [7]. So activate it under Scene -> Tools -> Digital Confusion.
I am still very much a n00b with this plug, so I know nothing about optimal
settings or deeper configurations, so I'll just help you to some normal
settings that suits this image. Set the 'Autofocus' to your Virus object.
And an 'F-Stop' of 0.3 as in figure 6. |
|
8. THERE!
Now all we need to do is setup the camera. So go into the 'Camera Properties',
set your resolution to whatever you want and change the 'Antialiasing'
to suit your needs. Figure 7.
|
9.
Now render out your cute little cuddly microbe. Take it into Photoshop,
add a background and some colour. And whee!! You have a genuine Niklas Industries
BioChem Dept. microbe. Figure 8. |
