The enhancement functions of RTI reveal surface information that is not disclosed under direct empirical examination of the physical object. The Sennedjem Lintel from the Phoebe A. RTI images are created from information derived from multiple digital photographs of a subject shot from a stationary camera position.
In each photograph, light is projected from a different known, or knowable, direction. This process produces a series of images of the same subject with varying highlights and shadows. Lighting information from the images is mathematically synthesized to generate a mathematical model of the surface, enabling a user to re-light the RTI image interactively and examine its surface on a screen.
Each RTI resembles a single, two-dimensional 2D photographic image. This changing interplay of light and shadow in the image discloses fine details of the subject's 3D surface form.
A Cultural anthropology term paper paper describing these first tools and methods, named Polynomial Texture Mapping PTMwas published in Since then, RTI research, application development, and evaluation in practical-use environments remains very active.
Many new RTI tools, methods, and uses have emerged. Go to our Downloads area to access the most recent versions of the software and user guides. Participate in the CHIForums to learn about new projects and new research.
How does it work? Mathematically, the direction that is perpendicular to the surface at any given location is represented by a vector direction called a normal Figure 1. Technically it is a vector that is perpendicular to the tangent plane at any point on the surface, as real surfaces are in 3D and this graphic is only 2-dimensional.
Figure 1 Light bounces off of surfaces such that the incident angle of the light and the reflected angle of the light are equal angles to the surface normal.
Since the camera is in a fixed position, and we know where the light is coming from in each image, and because we sample from a variety of light positions, RTI software can calculate the surface normal per pixel in the image. Figure 2 The mathematical description of the normal is saved per pixel, along with the RGB red-green-blue color information of a regular photograph.
This ability to record efficiently the color and true 3D shape information is the source of RTI's documentary power.
Figure 3 shows the reflection information captured in the RTI. Figure 3 Examples There are three video examples embedded below, each showing a different example of how RTI can be applied in the study of cultural heritage objects.
