Vectorworks 2010 Products 87Vectorworks Spotlight 2010 Getting Started GuidePoint LightNote: The drop down menu in the OIP that allows you to changeone type of light to another. Great for our exploration here.Point Lights serve a great many functions, but they can really addto rendering times as they are just like an uncontrolled or focusedlamp sitting in space. Great for backlighting objects.In my Lighthouse Model, I used a very high powered point light infront of a reflective surface to simulate the light house light.IES Files and Custom LightsIES files contain Photometric data. Most manufacturers provide IES files for their lighting products online. When you select the CustomLight option in the Tool Bar you can load an IES file and create a light in the 3D world based on commercial photometric data.Imagine being able to create a table lamp and look at the fixture with different sources, possibly tungsten or CFL before manufacturing.You will find a library of custom lamps including glass enclosures in the Libraries.Line Lights and Area LightsLine Lights and Area Lights are great sources for creating neoneffects, edge lighting, illuminated bars and the like. To createeither, start with a 2D primitive line or shape (either for LineLight, shape for Area Light) and go to Modify>Convert andeither Convert to Area Light or Convert to Line Light. Note thatyou can also import an IES file to define a Line or Area Light.Observe the small RedArrow when a Line light or Area Light is selected indicatinglight direction.Like so many other things, these lights will add considerably torendering time in large models. They are especially well suitedto Radiosity Rendering, but can be used in Final or CustomRenderworks.Lit Fog OptionWhile this is way cool, be well warned that clicking the lit fog option will have a huge impact on your rendering time. Please try only witha mighty system and lots of RAM.
