By identifying the aesthetics of the design structure of collage artwork, including its visual values, based on spaces, colors, and various textures, as well as materials as formative media, and the associated structural foundations and relationships that govern the relationship between the surfaces of the artwork and the materials added in the collage technique. Meanwhile, numerous relationships are realized between the structural foundation of the flat and three-dimensional artwork and the technical dimensions of the integrated collage processes. With the development of three-dimensional design techniques, collage has acquired new compositional dimensions that contribute to enhancing the depth of the composition and highlighting the interactions between layers and materials. This research aims to uncover the compositional dimensions of collage in three-dimensional designs by analyzing the relationships between visual elements and evaluating the impact of factors and material interactions on the overall structure of the artwork. Collage in 3D design is not just a process of combining visual elements, but rather a powerful means of highlighting spatial formations and activating the sense of volume and depth. Its role in this context can illustrate several aspects, including: enhancing spatial depth and different layers, interweaving between materials and highlighting masses and formations, whether independent or interconnected within a comprehensive composition, and interacting with lighting and materials, which enriches the visual perception of mass and space, in addition to the dynamic depth of the structure and the visual rhythm of movement within space.
