threeform

Threeform may refer to several different concepts or brands across disciplines. In mathematics and differential geometry, a three-form (or 3-form) is a differential form of degree three. On an oriented n-dimensional manifold, a three-form is an alternating multilinear object that can be integrated over three-dimensional submanifolds. Three-forms are part of the exterior algebra, and operations such as the wedge product and exterior derivative relate three-forms to other differential forms. They appear in various theories, including volume calculations, flux integrals in physics, and in the description of calibrated geometries.

In Hindu philosophy and theology, discussions about “three forms” appear in reference to triune representations of the divine, notably the Trimurti consisting of Brahma, Vishnu, and Shiva. This triadic conception embodies creation, preservation, and destruction as cosmic functions; while often described as a single triune form, the terminology varies by tradition and text.

In architecture and design, Threeform is a brand name used for a line of architectural glass and resin products. The company is known for creating translucent panels and artwork that combine glass and resin to form modular, light-transmitting surfaces for interior and exterior installations. Materials and finishes are marketed as sustainable and design-oriented, and the products are used by architects, designers, and artists.
