A point or finite symmetry is a coherent single shape or object that is dimen-sionless because it is defined by its center. One-dimensional symmetries extend in a single direction only. Examples of these are decorative friezes or bands. There are a total of seven one-dimensional symmetry types.

Symmetry and regularity abound in architectural models, often as a result of economical, manufacturing, functional, or aesthetic con-siderations. We show how recent work on symmetry detection and structure discovery can be utilized to analyze architectural designs and real-world artifacts digitized using 3D scanning technology. This allows reverse ...
The analysis of digital 3D models using the methodology described above provides us with a compact representation of the symmetries and repetitive structures of a shape. We first show some examples and then discuss how this information can be utilized to provide effective tools for shape exploration and manipulation in the context of architectural ...
We discussed how symmetry and structure discovery algorithms can be exploited for shape analysis and synthesis in the context of architectural design. These tools provide a first step towards a more comprehensive framework for procedural modeling based on reverse-enginerring of shape design rules. The analysis of symme-try and repetitive structures...
We thank our collaborators Leonidas Guibas, Helmut Pottmann, and Johannes Wallner for important contributions to this work. Figure 4: Large-scale symmetries detected in a digital model of the Sydney opera. The extracted symmetries include reflections, as well as general similarities that involve uniform scaling, rotation, and translation. Figure 5:...
Translation symmetry moves a shape a constant distance in a line. Reflection symmetry flips a shape across a line and the line can be vertical or horizont al. Glide symmetry involves a translation and reflection.
Jan 1, 2008 · In this work, we detect the intrinsic reflective symmetry in triangle meshes where we have to find the intrinsically symmetric point for each point of the shape.
Oct 2, 2015 · Repetition of geometric shapes, lines, and reflections can be found in and used as symmetrical elements in architectural design. Geometry Search Journal Target: Identifies geometric shapes/figures, lines, and transformations in architecture. Criteria: Draws, labels, and describes properties/attributes of polygons, parallel and
Jan 1, 2018 · Geometry intervenes in the creative and conceptual process in three forms: as a. language, as a representation or as structure. Symmetry, in the words of Hermann Weyl, both in the broadest...

What is asymmetrical balance in design?
Balance in design refers to the equilibrium or equality of visual attraction (Figure 6). Symmetrical balance is achieved when one side of the design is a mirror image of the other side. There is a distinct dividing line between the two sides. Equal lines, forms, textures or colors are on each side of a symmetrical design.
