Color Plate 1: Final results of the SSAO technique presented in Gem 1.2. The top-left pane shows lighting without the ambient occlusion, while the top-right pane shows lighting with the SSAO component mixed in. The final colored result is shown in the bottom image. Here the SSAO samples are very wide, bathing the background area with an effect that would otherwise only be obtained with a thorough global illumination algorithm. The SSAO term adds depth to the scene and helps anchor the characters within the environment.
