3D fonts are a type of typography that gives the illusion of depth and dimension to text, making it appear as if it is popping out from the surface. These fonts are designed using various techniques, such as shadowing, shading, or extruding, to create a three-dimensional effect. They are often used in graphic design, advertising, and digital media to add visual interest and enhance the overall impact of a design. With the rise of virtual and augmented reality technologies, 3D fonts are becoming increasingly popular for immersive experiences, providing a unique and engaging way to present text content in these environments.
