📄️ Bitmap Image
A bitmap image is a image format whereby each pixel is one of two values: black or white.
📄️ Cloth
The product of weaving as well as other textile processes such as knitting or crochet.
📄️ Dataflow
A dataflow is created when drafts and operations are connected together by selecting the outlet of a draft and connecting it to an inlet of an operation.
📄️ Direct Tie Loom / Dobby
A horizontal loom where each warp is threaded through a heddle, and each heddle belongs to one of a given set of frames. When a frame is raised, so too are the heddles and warps within those frames.
📄️ Draft
A draft is an abstract representation of a cloth. For example, the two images below show the correspondence between a simulated cloth and the draft that would be used to create the cloth.
📄️ Drafting Style
Different approaches to drafting are used to plan cloth on different looms. In this context, we refer to these approaches as "Drafting Styles" and offer support for two different kinds of drafting styles which we call drawdown-first or threading-first approaches.
📄️ Drawdown
We use the term drawdown to describe the part of the draft that represents the structure of the resulting cloth.
📄️ End
Refers to a single warp within the collection of warps
📄️ Harness Loom
A horizontal loom on which each warp yarn is threaded through a heddle, and each heddle is attached to one of a given set of "harnesses" "frames" or "shafts". When a harness is raised, so too are the heddles and warps within those frames. Harness looms can come with sets of two to 32 harnesses.
📄️ Inlet
Coming soon.
📄️ Jacquard Loom
A horizontal loom where each warp is threaded through a heddle, and each heddle can be individually controlled, often through a computer interface.
📄️ Layer Notation
Layer notation emerged in conversation with Kathryn Walters, who wanted AdaCAD to help her manage complex structures that could arbitrarily map warp and weft systems to different layers, layer orders, or even different numbers of layers (e.g. a structure that goes from 2 to 4 to 3 layers for instance.) Beyond her immediate needs, we found it to be a useful system for describing the relationship between different cloth layers.
📄️ Loom
A device used to scaffold the weaving process. Looms can take various shapes and forms. They tend to share the ability to hold a set of parallel yarns (e.g. the warp) in tension between two beams.
📄️ Material
AdaCAD uses colors to represent and at times, simulate, the color of materials to be used when weaving the cloth.
📄️ Operation
Operations are little computational machines that take drafts as inputs, do something to them, and then spit them out as new and different, drafts. An operation consists of several parts: inlet(s), parameters, and a resulting draft with an outlet.
📄️ Outlet
Coming soon.
📄️ Parameter
Function parameters are used to declare the input values for AdaCAD operations.
📄️ Parametric Design
AdaCAD takes a 'parametric design' approach to creating woven structures and drafts.
📄️ Pick
Refers to a single weft insertion.
📄️ Structure
Coming soon.
📄️ System
In this context, we use the term system to describe groupings of warps (e.g. warp systems) or wefts (e.g. weft systems) that will form specific design relationships. For example, it is common to think of multi-layer weaves as working by interlacing certain wefts upon certain warp systems and then lifting those systems out of the way to create "layered" structures. In another case, you might think of a double sided twill operating of two weft systems, one that will weave on the weft-facing side of the warp and the other on the warp-facing side.
📄️ Warp Lowered
Another way to refer to white cells in a drawdown. We use this terminology represent locations where the warp is raised and white cells as “warps lowered”.
📄️ Warp Raised
Another way to refer to black cells in a drawdown. We use this term to highlight the relationship between cells in a drawdown and actions on a loom. Specifically, it tells us that a black cell is a location where the warp end is raised. This is in contrast to white cells, which describe locations where the “warp is lowered”.
📄️ Warp
The collection of parallel yarns held in tension across the loom. Cloth is made by working weft yarns into the warp.
📄️ Weft
The weft or "filling" yarn describes the yarn worked into warp. It is typically inserted perpendicularly to the warp and interlaced over and under the warp.
