How to fill out using polynomial texture maps

How to fill out using polynomial texture maps:

1. Begin by understanding what polynomial texture maps (PTMs) are. PTMs are a computational imaging technique used to capture and manipulate the surface appearance of an object. They are typically used in cultural heritage preservation, archaeology, and forensics.
2. Capture a series of digital photographs of the object from different lighting angles. It is crucial to have a controlled setup, where the object remains stationary, and the lighting remains consistent.
3. Next, process the captured images using specialized software. One popular software for PTM processing is called PTMFitter. This software uses the images to generate a PTM file, which contains the visual information needed to interactively relight the object.
4. Open the PTM file in a PTM viewer/editor. Some widely used PTM viewers/editors include RTIBuilder, PTGui, and Polynomial Texture Tools (PTT). These tools provide a user-friendly interface to manipulate the lighting condition and interactively relight the object.
5. Experiment with different lighting conditions in the PTM viewer/editor to highlight specific details or enhance the object's appearance. You can change the direction, intensity, and color of the virtual light sources to create desired effects.
6. Once you are satisfied with the final result, export the PTM file in a suitable format for your intended use. Common formats include PTM-XML, PTM-binary, and PTM-JPEG.

Who needs using polynomial texture maps:

1. Cultural Heritage Professionals: PTMs are widely used in the preservation and analysis of cultural heritage objects like ancient artifacts, paintings, and sculptures. They can reveal hidden details, enhance faded colors, and provide a non-invasive method for examining delicate surfaces.
2. Archaeologists: PTMs can help archaeologists study inscriptions, markings, and textures on artifacts, pottery, or stone surfaces. By manipulating the lighting conditions, PTMs can bring out hidden or faded information that might not be visible in conventional photography.
3. Forensic Experts: PTMs are valuable in forensic investigations where accurate documentation and analysis of evidence are crucial. They can aid in the examination of fingerprints, document forgeries, or other microscopic details that might be obscured in regular photographs.
4. Computer Graphics and Animation Professionals: PTMs are also used in the field of computer graphics to create realistic 3D models with accurate surface details and realistic lighting effects. They can be used in the production of visual effects for movies, video games, or virtual reality experiences.
5. Researchers in Materials Science: PTMs can be used to analyze and characterize different material properties, such as surface roughness or glossiness. This information can be useful in various fields like material science, engineering, or product design.

In conclusion, polynomial texture maps provide a powerful tool for capturing and manipulating the surface appearance of objects. Their applications range from cultural heritage preservation to forensics, archaeology, computer graphics, and materials science.
