Two grease pencils Historical diplomatic usage The grease pencil , a wax writing tool also known as a wax pencil , china marker , or chinagraph pencil (especially in the United Kingdom ), is a writing implement made of hardened colored wax and is useful for marking on hard, glossy non-porous surfaces.
The original version of the software was called Pencil, created by Patrick Corrieri and Pascal Naidon in 2005, [4] but was abandoned and discontinued in 2009. The abandonment of the project led to the creation of numerous forks, several of which were eventually merged into that of Matthew Chang, resulting in the project now known as Pencil2D.
A pencil of planes, is the set of planes through a given straight line in three-space, called the axis of the pencil. The pencil is sometimes referred to as a axial-pencil [7] or fan of planes or a sheaf of planes. [8] For example, the meridians of the globe are defined by the pencil of planes on the axis of Earth's rotation.
A pencil is a particular kind of linear system of divisors on , namely a one-parameter family, parametrised by the projective line. This means that in the case of a complex algebraic variety V {\displaystyle V} , a Lefschetz pencil is something like a fibration over the Riemann sphere ; but with two qualifications about singularity.
A pencil-beam radar A moving or sweeping pencil-beam radar. In optics, a pencil or pencil of rays, also known as a pencil beam or narrow beam, is a geometric construct (pencil of half-lines) used to describe a beam or portion of a beam of electromagnetic radiation or charged particles, typically in the form of a cone or cylinder.
In geometry, straightedge-and-compass construction – also known as ruler-and-compass construction, Euclidean construction, or classical construction – is the construction of lengths, angles, and other geometric figures using only an idealized ruler and a pair of compasses.
