Opaquetransparent

Opaquetransparent is a term used to describe surfaces that combine opaque and transparent regions or states within a single object. It denotes variable light transmission across a surface, producing areas of clarity and obscurity or a surface that can switch between opaque and transparent modes.

The concept covers physical materials with spatially varying opacity, such as patterned or frosted glass with clear patches, and layered composites where translucent layers sit beside opaque ones. It also includes digital or smart materials that change opacity dynamically, as well as images or interfaces that use alpha channels to blend visibility.

Applications span architecture, product design, displays, and media to control light, privacy, or aesthetics. Examples include laminated glass with internal patterns, electrochromic or photochromic smart glass, frosted screens with transparent windows, and user interfaces that reveal content through selective transparency.

Design considerations focus on optical contrast, legibility, color rendering, and accessibility, since variable opacity can affect perception. Durability, weather resistance, and safety matter for architectural uses.

The term is not widely standardized but conveys a spectrum between full opacity and full transparency, encompassing both fixed patterns and switchable states.
