Radiosity
Hello, in this informative Review I will start by telling you about Radiosity and what it is.
Let's start by understanding radiosity. Radiosity calculates diffuse reflections of color and light from all surfaces in a scene. A good way to think of it is the light is bouncing off a surface helping to light a room. Radiosity is all around you, take a look around your house for example, look at a lamp next to a wall in your house and you will see the light bouncing off the wall or a window with the light shining threw it on to the floor.
Achieving Photorealism is not something
that is easy to do, most people think it's
done in the modeling part of your work but
in fact modeling is only about 40% of your
work, the other 60% is spent on texturing
and lighting. I tend to see a lot of people
displaying their models just floating in a
white background and saying 'rendered with
radiosity', the model is good but it looks
bad because of its' lighting. This is because
they did not take the time to find out how
radiosity works.
One thing to remember about working with radiosity
is that using it takes much more time to render,
depending on your settings. Some of the photos
seen in this informative Review took up to
5 hours to render on a Pentium 4 with 640
megs of RAM!
LightWave 3D's renderer has long been considered
the best in the industry and I have found
it to be the most powerful 3D tool I have
used.
Photorealism, Radiosity, Aged Film with Virtual Darkroom
Virtual Darkroom is an image processing plug-in which simulates photographic capture of Lightwave rendered images.
Aged Film is achieved with the use of the Plug-in Virtual Darkroom that comes standard in LightWave 6.5. With right setting this plug-in can do some amazing work.
Some of the things filmmakers have tried to eliminate over the years like lens flares and aged film are now special effects in the 3D world.
Here are some of the photorealism works that can be achieved with LightWave 3D's rendering system.
