Tell me the details: Freeform optics involve optical designs with at least one freeform surface which, according to the ISO standard 17450-1:2011, has no translational or rotational symmetry about axes normal to the mean plane. Nonimaging and illumination optics have leveraged freeform surfaces since at least the 1990s [1]. Integration of freeform optics and surfaces into imaging systems remains as a major challenge. However, the new degrees of freedom introduced by freeform optics designs are the driver to overcoming these challenges. These additional degrees of freedom enable many potential advantages, including system miniaturization, reduced component count and even entirely new optical functionality that will have a profound effect on the optics industry.

In Nordic larp, the term is usually taken to mean the freeform traditions of Sweden and Denmark, centred on the Fastaval convention. Such freeforms are often larp-like in the sense that players may move and gesticulate in-character, but are played with only 3-8 players who remain in the same room. Freeforms tend to be strongly narrative, with a GM taking the players from scene to scene. They are usually based on a repeatble, written, scenario.
Plenty of angry debates have been held on the topic of whether freeforms are larps or not. The stereotypical freeform can be distinguished from the stereotypical larp by the presence of an active narrator in the former and the latter having costumed players spread over a larger area with scenography adapted to the fiction. However, due to experimentation in both larp and freeform communities, these borders are often blurry.
In Illustrator, a freeform gradient is used to create a graduated blend of color stops within a shape in an ordered or random sequence such that the blending appears smooth and natural. A freeform gradient can be applied in two modes:
Purpose-built logic for operational planning enables large-scale, freeform, and ad-hoc modeling for operational planners. Financial planners can leverage models with built-in financial intelligence to gain greater insights for more efficient budgeting and forecasting
Most tissue engineering (TE) strategies for creating functional replacement tissues or organs rely on the application of temporary three-dimensional scaffolds to guide the proliferation and spread of seeded cells in vitro and in vivo. The characteristics of TE scaffolds are major concerns in the quest to fabricate ideal scaffolds. This paper identifies essential structural characteristics and the pre-requisites for fabrication techniques that can yield scaffolds that are capable of directing healthy and homogeneous tissue development. Emphasis is given to solid freeform (SFF), also known as rapid prototyping, technologies which are fast becoming the techniques of choice for scaffold fabrication with the potential to overcome the limitations of conventional manual-based fabrication techniques. SFF-fabricated scaffolds have been found to be able to address most, if not all the macro- and micro-architectural requirements for TE applications. This paper reviews the application/potential application of state-of-the-art SFF fabrication techniques in creating TE scaffolds. The advantages and limitations of the SFF techniques are compared. Related research carried out worldwide by different institutions, including the authors' research are discussed.
You can use AI Builder document processing to create freeform document processing models that use machine learning technology to identify and extract key-value pairs and table data from unstructured or freeform documents, such as contracts and correspondence. 2ff7e9595c
