RaisedEdges

RaisedEdges is a rendering and design technique used to create the appearance of raised borders along the edges of shapes, panels, or text in digital media. The effect simulates physical depth by applying light, shadow, and beveling to make edges protrude from the surrounding surface.

In practice, RaisedEdges can be produced by a variety of methods, including bevel filters, inner and outer shadow layers, or shader programs that compute edge elevation based on lighting direction and edge geometry. Common parameters include edge thickness, bevel depth, light direction, shadow intensity, and highlight strength.

Applications include user interface design for buttons, cards, and panels, as well as graphic design, posters, and game assets where a tactile, embossed look is desired. It helps to visually separate adjacent regions and communicates interactive elements without relying solely on color or texture.

RaisedEdges is related to emboss, deboss, and stroke effects; the key distinction lies in how light interacts with the edge to create the sense of elevation and surface break.

Considerations include rendering performance in real-time environments and accessibility concerns, since strong raised edges can affect contrast and legibility for some users if not balanced with other cues.
