The lateral force of the probe tip was measured along with the topography. We intend to use image and bump-map textures, together with color and contour lines, to indicate multiple data sets simultaneously. The PixelFlow graphics engine will enable us to do this rendering in real time, as experiments are being done. This is a visualization done for Stan Williams' group at HP science labs. These are germanium pyramids and domes grown on silicon.
Color is from curvature information, using the black-body radiation spectrum.
Gridlines are drawn on 100nm boundaries in the left image, 10nm boundaries on the right. The image on the right is a close-up view of the image on the left, from a different angle. The numbers show the distance in the plane and vertical to the plane, indicating relative heights of the two bumps. Click here for a JPEG of the left image. Click here for a JPEG of the right image.
