TABLE OF CONTENTS To introduce the use of the Render tools in producing photographic like images of 3D solid models.
To show how to illuminate a 3D solid model to obtain good lighting effects when rendering.
To give examples of the rendering of 3D solid models.
To introduce the idea of adding materials to 3D solid models in order to obtain a realistic appearance to a rendering.
To demonstrate the use of the forms of shading available using the 3D Orbit tool.
To demonstrate methods of printing rendered 3D solid models.
The use of the Render tool has already been shown in examples in previous pages. More realistic images can be produced using the tool, if lights, colours and/or materials are added to the 3D model being rendered. All the tools in the Render toolbar have already been shown on page 174.
There are four types of lights available when using AutoCAD Ambient lights, Point lights, Distant lights and Spotlights.
Ambient lighting is taken as the general overall light that is all around and surrounding any object. When rendering in AutoCAD Ambient light is generally set at a default value of 0.3.
Point lights shed light in all directions from the position in which the light is placed and diminishes in intensity the further from the light that an object is placed.
Distant lights send parallel rays of light...
