Vertex Lighting

Lighting methods typically come in three different flavours: flat polygon lighting, vertex lighting, and pixel lighting.

Vertex lighting uses the vertexes of a 3D shape as the targets for lighting. The engine determines how many polygon planes touch a given vertex, takes the mean of their collective orientations, and calculate how much light to apply to that polygon based on a calculation between the amount of light reaching the vertex, and that mean. It creates a slow gradient across each polygon as each vertex has a different light value, and generates a different mean value.

A major disadvantage of vertex lighting, is it is incapable of producing shadows, or working out which polygons should not be lit, even if they have a vertex that is.

Hemisphere Lighting With Radiosity Maps
Rendering of lighting in outdoor scenes is a paramount concern. To truly be realistic, the light levels constantly vary, and the sun (or suns) are not usually even the primary lightsource! All that adds up to is a computational disaster, unless some way is found to render lightsoure data quickly, and easilly....

High Dynamic Range Photography, and Use in Eye Emulation
H.D.R., or high dynamic range photography is a relatively new technique used by photographers to take high-quality full lighting range photos that are near-indistinguishable from paintings, for their ability to correctly replicate the lighting of a given scene, exactly how the human eye would see it.

Wearable Display Jackets
The concept of clothing that integrates lighting displays is one that has only recently been realised, yet it hasd been in cyberpunk a long, long time. The original 'electropigment' dating back to Snow Crash itself.



This tome is, as the4 title suggests, more of an overview for the subject than a detailed how-to. It covers everything from the very basics of computerised model animation, right through rigging and boning, on to timing and lighting ? but it does so without going into painstaking detail on any one topic.

Room Lighting as Network Access
A new method of creating wireless networks without interfering with sensitive equipment, including medical equipment, is to make use of the rapid on/off capabilities of LEDs in normal modern LED lightbulbs. 800mb/s is the current limit, and that is only in the prototype.

A team working at Brown University, believe they have made a breakthrough in robotic vision systems: A robot that follows a person from room to room to room, tracking them regardless of lighting conditions, crowds milling between the user and the robot, temporary obstructions or anything.

Optical Tracking of Zebrafish Neural Impulses
Zebrafish are handy little critters, as far as neuroscience goes. These tiny, mostly transparent little fish have brains that whilst greatly simplified, have a structure remarkably similar in basic form, to our own. Add in that aforementioned near-transparency, and it becomes possible under the correct lighting conditions, to literally see right into their brains, to the point where you can practically watch as a thought takes place.
