Working with irradiance mapping


show more Irradiance mapping is the primary tool in Google SketchUp for simulating the way light (both daylight and electronic lighting) passes around a scene. Using the tool lets you run a render that shows the various ways objects will be illuminated by reflected light. One neat aspect is that the rendering builds up the reflected light layer by layer so that you can spot obvious flaws as early as possible.

Working with irradiance mapping

Because Global Illumination is such an important part of the V-Ray artist toolkit, we're going to spend the entirety of this chapter examining most of the GI engines available to us in V-Ray. In this particular video, we're going to focus on using V-Ray's irradiance mapping engine and just create a basic global illumination solution for our interior start scene. This scene has once again been somewhat artificially engineered. We are making use of the V-Ray Sun and Sky system to provide our daylight illumination.

However, we have disabled Indirect Illumination in our scene. This of course means that our interior at this moment of time is in almost complete darkness. In fact, if we just come up to our V-Ray toolbar and use the Start Render icon, you will be able to see exactly what we mean. What we have at this moment of course is a direct-light-only render. Now, this of course can be very handy in terms of setting up our scene lighting. We are able to see exactly ...
