A rendered image can incorporate a variety of rendering features. Some of these features are available in SketchUp, using OpenGL, and some are only available with SketchUp Plugins for high end rendering applications.

  • Antialiasing — the process of making edge lines look smoother by blending in the colors at the edges.
  • Bump Mapping — a method of simulating small-scale bumpiness on surfaces.
  • Depth of Field— objects appear blurry or out of focus when too far in front of or behind the object in focus.
  • Edge Highlighting — Accentuation edges.
  • Fog — how light dims when passing through non-clear atmosphere or air.
  • Glow — defining an object which appears to be illuminated by lights, even if it is in a shadow.
  • Morphing — “photoshopping” 3D renderings to appear more life-like.
  • Motion Blur— objects appear blurry due to high-speed motion, or the motion of the camera.

  • Non-Photorealistic Rendering — rendering of scenes in an artistic style, intended to look like a painting or drawing.
  • Indirect Light — incorporating additional illumination from lights reflecting from other surfaces.
  • Reflection — mirror-like or highly glossy reflection.
  • Refraction — bending of light associated with transparency.
  • Shading — how the color and brightness of a surface varies with lighting.
  • Shadows— the effect of obstructing light.
  • Soft Shadows — varying darkness caused by partially obscured light sources.
  • Texture Mapping — a method of applying detail to surfaces.
  • Translucency — highly scattered transmission of light through solid objects.
  • Transparency — sharp transmission of light through solid objects.
