Texture Development: Ambient Occlusion and Pre-rendered Lighting
Ambient Occlusion shading on a grayscale model of the Alchemy Sims Warehouse
Colored textures applied to warehouse model: baked-in lighting with mid-range render setting
Under different render settings: Low (no advanced shading) to High (real-time shadows)
FIGURE 6.18 Screen grabs from OpenSim, Alchemy Sims Grid. The top panel shows the Alchemy Sims Warehouse
model with just the ambient occlusion lighting on while it was being built in Blender. In the middle panel, the effect
of ambient occlusion and the colored texture maps is displayed. In the bottom panel are three views of the warehouse
showing various render settings available inworld and how they can enrich the image.
Data-driven Artwork and Data Visualization
Virtual interactive databased sculpture by Glyph Graves in Second Life
Created by Ann Cudworth (Annabelle Fanshaw) and Ben Lindquist (Arkowitz Jonson) on Alchemy Sims Grid
“Ancient Sun and a Fresh
Kansas Breeze”
Virtual wind driven sculpture
“Tidal Mills”
Tidal data driven
kinetic sculpture environment
“Barometric Bubbles”
Real time temperature data driven
bubble rezzing sculpture
“Forest of Water”
Each interactive “tree” represents
data from a river on Earth
“I thought I Hated Him”
“Dance” of the composite indices
from Shanghai and New York
“Memonic”
Temporal Geolocation in the Twitterverse

FIGURE 7.1 This chart shows the components of color. From the visible light color spectrum on the top, color models
are pulled out to display the RYB (red, yellow, blue) wheel, CMYK (cyan, magenta, yellow, key-black) model and the RGB
(red,green, blue) model. Subtractive color mixing is shown under the CMYK model and additive color mixing is shown
under the RGB model. Also included is the HSB (hue, saturation, and brightness) structure, bottom left.
