Twisted nematic LCs

Twisted Nematic (TN) LCs

by Dummy Admin

For nearly a hundred years after Friedrich Reinitzer observed cholesteryl benzoate changing into its liquid crystal state in 1888, nine years before the invention of the CRT, liquid crystals remained little more than a …

Super Twisted Nematic LC

Super Twisted Nematic (STN/DSTN) LCs

by Dummy Admin

The development of the twisted nematic liquid crystal (TNLC), with its 90° twist, made the production of commercially viable LCDs possible. Though relatively cheap to make and requiring very little power (hence their use …

Shadow Mask

by Dummy Admin

Before the stream of electrons produced by the CRT’s cathode reach the phosphor coated faceplate, it encounters the shadow mask, a sheet of metal etched with a pattern of holes. The mask is positioned …

flat shading


by Dummy Admin

Objects in 3D scenes are most commonly created by fitting together a large number of polygons (usually triangles), edge to edge, creating a “wire-frame” which approximates the object’s surface. By drawing only those triangles …

saddle-saddle yoke

Saddle-Saddle Yoke

by Dummy Admin

The most common form of deflection yoke used in early colour monitors is known as a saddle-toroidal yoke. Its name comes from the shapes of the vertical and horizontal deflection electro-magnets’ windings. The winding …

Ray Tracing

by Dummy Admin

Effective as they can be at producing recognisable 3D scenes, Gouraud and Phong shading will never produce anything that could be described as photo-realistic. To achieve this, it’s necessary to use rendering techniques that …

by Dummy Admin

Ray tracing mimics the reflection and refraction of light rays in a 3D scene to produce image detail surpassing anything possible using Phong shading. Effective as it is, though, ray tracing by itself will …

Point Sampling

by Dummy Admin

MIP-maps are used to store several different copies of a texture, at different scales, for use in 3D scene rendering. One of the accompanying illustrations shows four versions of a texture applied to flat …
