The Persistence of Vision Ray-Tracer creates three-dimensional, photo-realistic images using a rendering technique called ray-tracing. It reads in a text file containing information describing the objects and lighting in a scene and generates an image of that scene from the view point of a camera also described in the text file.
The Persistence of Vision Ray-Tracer(tm) was developed from DKBTrace 2.12 (written by David K. Buck and Aaron A. Collins) by a bunch of people (called the POV-Team?) in their spare time. The headquarters of the POV-Team is on the internet (see "Where to Find POV-Ray Files" for more details).
The POV-Ray package includes detailed instructions on using the ray-tracer and creating scenes. Many stunning scenes are included with POV-Ray so you can start creating images immediately when you get the package. These scenes can be modified so you do not have to start from scratch.
In addition to the pre-defined scenes, a large library of pre-defined shapes and materials is provided. You can include these shapes and materials in your own scenes by just including the library file name at the top of your scene file, and by using the shape or material name in your scene.
Ray-tracing is not a fast process by any means, but it produces very high quality images with realistic reflections, shading, perspective and other effects.
Ray-tracing is a rendering technique that calculates an image of a scene by simulating the way rays of light travel in the real world. However it does its job backwards. In the real world, rays of light are emitted from a light source and illuminate objects. The light reflects off of the objects or passes through transparent objects. This reflected light hits our eyes or perhaps a camera lens. Because the vast majority of rays never hit an observer, it would take forever to trace a scene.
Ray-tracing programs like POV-Ray start with their simulated camera and trace rays backwards out into the scene. The user specifies the location of the camera, light sources, and objects as well as the surface texture properties of objects, their interiors (if transparent) and any atmospheric media such as fog, haze, or fire.
For every pixel in the final image one or more viewing rays are shot from the camera, into the scene to see if it intersects with any of the objects in the scene. These "viewing rays" originate from the viewer, represented by the camera, and pass through the viewing window (representing the final image).
Every time an object is hit, the color of the surface at that point is calculated. For this purpose rays are sent backwards to each light source to determine the amount of light coming from the source. These "shadow rays" are tested to tell whether the surface point lies in shadow or not. If the surface is reflective or transparent new rays are set up and traced in order to determine the contribution of the reflected and refracted light to the final surface color.
Special features like inter-diffuse reflection (radiosity), atmospheric effects and area lights make it necessary to shoot a lot of additional rays into the scene for every pixel.
Main features:
- Easy to use scene description language.
- Large library of stunning example scene files.
- Standard include files that pre-define many shapes, colors and textures.
- Very high quality output image files (up to 48-bit color).
- 16 and 24 bit color display on many computer platforms using appropriate hardware.
- Create landscapes using smoothed height fields.
- Many camera types, including perspective, orthographic, fisheye, etc.
- Spotlights, cylindrical lights and area lights for sophisticated lighting.
- Photons for realistic, reflected and refracted, caustics. Photons also interact with media.
- Phong and specular highlighting for more realistic-looking surfaces.
- Inter-diffuse reflection (radiosity) for more realistic lighting.
- Atmospheric effects like atmosphere, ground-fog and rainbow.
- Particle media to model effects like clouds, dust, fire and steam.
- Several image file output formats including Targa, BMP (Windows only), PNG and PPM.
- Basic shape primitives such as ... spheres, boxes, quadrics, cylinders, cones, triangle and planes.
- Advanced shape primitives such as ... Tori (donuts), bezier patches, height fields (mountains), blobs, quartics, smooth triangles, text, superquadrics, surfaces of revolution, prisms, polygons, lathes, fractals, isosurfaces and the parametric object.
- Shapes can easily be combined to create new complex shapes using Constructive Solid Geometry (CSG). POV-Ray supports unions, merges, intersections and differences.
- Objects are assigned materials called textures (a texture describes the coloring and surface properties of a shape) and interior properties such as index of refraction and particle media (formerly known as "halos").
- Built-in color and normal patterns: Agate, Bozo, Bumps, Checker, Crackle, Dents, Granite, Gradient, Hexagon, Leopard, Mandel, Marble, Onion, Quilted, Ripples, Spotted, Spiral, Radial, Waves, Wood, Wrinkles and image file mapping. Or build your own pattern using functions.
- Users can create their own textures or use pre-defined textures such as ... Brass, Chrome, Copper, Gold, Silver, Stone, Wood.
- Combine textures using layering of semi-transparent textures or tiles of textures or material map files.
- Display preview of image while rendering (not available on all platforms).
- Halt and save a render part way through, and continue rendering the halted partial render later.

LMarbles is an Atomix clone with a slight change in concept. Instead of assembling molecules you create figures out of marbles. Nevertheless, the basic game play is the same: If a marble starts to move it will not stop until it hits a wall or another marble.

To make it more interesting there are obstacles like one-way streets, crumbling walls and portals.

As Marbles is meant as a puzzle game you play against a move limit and not a time limit. This way you have as much time as you need to think.

PHPrbl is a quick and easy tool that keeps clients using open proxies away from your site in order to reduce referrer spam.
Ever had those annoying referrer spammers ruin your websites statistics? If you run a big website, or a weblog, you must be getting fed up with this blasted referrer spam.
Youre not alone, I have this problem as well and got fed up with the whole thing. After weeks of playing with the idea of blocking referrer spammers using rewrite rules, I got fed up wit the high amount of energy it would demand of me just to block IP addresses that seemed to be open proxies anyway.
Enhancements:
- Streamlined the code based on input given by Steven Lynn. Fewer queries are now used to do the same thing. Thanks!
- New feature: keywords checking; referrers are now matched to keywords given by the site admin. If a match occurs, the client will be blocked. (For myself this feature has already proven to be very, very effective)
- First start of an admin area for PHPrbl, for now, only the ability to add and removed keywords is present. Whitelisting and local IP blocklist management will be added soon.

Papagayo is a lip-sync program to synchronize animation with audio.

Papagayo is a lip-syncing program designed to help you line up phonemes (mouth shapes) with the actual recorded sound of actors speaking.

Papagayo makes it easy to lip sync animated characters by making the process very simple - just type in the words being spoken (or copy/paste them from the animations script), then drag the words on top of the sounds waveform until they line up with the proper sounds.

Papagayo is designed to be used with Moho, a 2D cartoon animation program, but since its open source, it can be modified for use with other animation applications.
