ZBrush is a digital sculpting tool that combines 3D/2.5D modeling, texturing and painting. Using the default 3D viewport drawing system for modeling, texturing, etc. Instead of sprites the engines used simply textured (single-pass texturing, no lighting details) polygonal objects. Currently, surface texturing techniques on silicon photovoltaics are drawing much attention. This is achieved using a combination of hair coloring, haircutting, and hair texturing techniques. Applications include hardening, annealing, tempering, texturing, and polishing (with argon gas present). Surface texturing could be done in multiple ways. He used dark jeweled colors with muted shades accentuated with subtle texturing and indigenous embroidery. This process happens in three steps&colon; segmentation, texturing and flattening. Reflection can be reduced by texturing the surface with 3D pyramids or 2D grooves (gratings). Control and restraint were exercised in the use of surface texturing and relief. Trail preparation employs snow machines which tow snow-compaction, texturing and track-setting devices. Other tools such as mezzotint rockers, roulets and burnishers are used for texturing effects. Another issue with the card's texturing was its use of automated mipmap generation. The texturing process starts with a location in space.
