Each of the three types of rendering is used to create different effects, and each renders at a different speed.

AutoCAD uses geometry, lighting, and materials to render a realistic image of a model. For a presentation, a full rendering might be appropriate. If time is limited, or if your display and graphics equipment cannot produce varied gradations and colors, you might not need a detailed rendering. If you want a quick check of the integrity of a design, a simple hidden-line or shaded image is sufficient. For information about hidden-line or shaded images, see Hide Lines or Shade 3D Objects.

Note It is strongly recommended that you have a 3D graphics card if you plan to use Render options, particularly textures and higher quality transparency.

AutoCAD Render provides three rendering types:

  1. Render, the basic AutoCAD rendering option for best performance
  2. Photo Real, the photorealistic scanline renderer, which can display bitmapped and transparent materials and generate volumetric and mapped shadows
  3. Photo Raytrace, the photorealistic raytraced renderer, which uses ray tracing to generate reflections, refraction, and more precise shadows

Using the basic Render option, you can render your model without applying a material, adding any lights, or setting up a scene. When you render a new model, the AutoCAD renderer automatically uses a virtual "over-the-shoulder" distant light. You cannot move or adjust this light.

AutoCAD Render is automatically loaded into memory when you choose an option on the Render toolbar or enter an AutoCAD command such as FOG, LIGHT, RENDER, or SCENE. You can stop the rendering process by pressing ESC. To free memory, you can unload AutoCAD Render.

Rendering often requires the most computer time in a 3D project. It generally involves three steps:

  1. Preparing models. Includes following proper drafting techniques, removing hidden surfaces, constructing meshes for smooth shading, and setting view resolution.
  2. Illuminating. Includes creating and placing lights and creating shadows.
  3. Adding color. Includes defining the reflective qualities of materials and associating these materials with the visible surfaces.

Rendering usually includes rendering objects at intermediate steps to check your preparation, illumination, and colors.
