Rendering with MicroStation
Through illustrations and hands-on exercises, this book covers every aspect of rendering in detail, including cameras, materials, lighting, environment maps, and rendering settings.

Chapter 4: Global and Source Lighting
Overview
Of all of the tools and techniques for achieving truly photorealistic results, when rendering with MicroStation, lighting has the most impact. Without correct illumination, a 3D scene will look very flat and two-dimensional. This chapter presents the lighting tools in MicroStation and how to properly use them to improve your rendering results.
MicroStation provides two types of lighting: source and global. Source lighting is created via special cells that you place in a model and is covered later in this chapter. Global lighting is available for a DGN file (all models) via settings in the Global Lighting dialog box.
Global Lighting
When you first began to render with MicroStation, you picked a rendering method and hoped for the best. If you were lucky, the model already had decent global lighting configured, and the rendering results were acceptable, if not a bit mediocre. This was a result of the Solar, Ambient, and Flashbulb Light settings, inherited from the original 3D seed file.
In the following exercises, you will begin by ray tracing a view in a model, using the current global lighting settings. Following this, you will adjust settings for the global lighting to improve the image.
Exercise 4-1: Review the effect of global lighting
-
Open Global Lighting.dgn.
You will ray trace View 2 with the current global lighting settings. Since you do not have a ray trace solution yet, the only option will be to Create a new solution.
