Texture mapping: part two
Following the positive feedback from my first post, here are two further designs represented using Polynomial Texture Mapping (PTM), including one application of Reflectance Transformation Imaging (RTI). These designs were chosen in order to explore the effects of this image capture and processing technique on shiny surfaces: a ‘gilded’ and embossed envelope showing the Crystal Palace, and knitted silk gloves with ‘floss’ silk tassels.
