== Introduction ==
The Canvas 3D JS Libary (C3DL) is a javascript Javascript library that will make it easier to write 3D applications using canvas 3dWebGL. It will provide provides a set of math, scene, and 3d object classes to make the canvas more accessible for developers that want to develop 3D content in browser.

== Downloads ==
NOTE: these downloads are mostly meant for in-house testing and not really polished. It may also only work on a specific platform only. please read the note regarding the download.
<BR>
For the library, samples, and tutorials, go to [http://cs.senecacwww.onc3dl.caorg/~leung/canvas3d/canvas3d-0c3DL.2.0.xpi Andrew's patchorg] - this change to the canvas 3D extension allows the "simple" examples from Vlad's page to work with ati cards. This is intended for Windows only. Model viewer examples do not work yet.

== Math Operations Documentation ==
=== Vector Class ===A Vector basically describes a direction in the form of X, Y, and Z coordinates of a 3D worldDocumentation can be found on our website: [http://www.c3dl.org/index. Basic 3D math cannot exist without the utilization of spatial coordinates which the Vector Class encapsulatesphp/documentation/ c3DL.org]. The Vector Class will have the following members within it:

== Camera ==* 3D Photo Album - Download images and create a 3D photo album similar to [http://www.mypictures3d.com/images/screenshots/art_gallery/art4.jpg this].
=== Pan Camera Class ===* INCOMPLETEMatrix - Query search engines for sites, chat logs, blogs, etc. and display all the text in a matrix-like fashion.
=== Fixed Camera Class ===* Really fancy animation of a bar graph, with columns growing and arrow moving. Will be an instant hit with business people. Usable as easy as [http://code.google.com/apis/chart/ google's toy]* INCOMPLETE[[Image:higherhigher.jpg]]
=== Chase Camera Class ===* INCOMPLETEGeneric model viewer application, with back/forward/index + zoom/rotate buttons that would download and display models from the web. Would have to be able to convert 3dsmax models in JS. So a museum or such could just slap the app on the page and give it an array of URLs for the stuff to show.
=== Free Camera Class ===The Free Camera Class is a camera that can be translated and oriented* Pong. It cannot Should be attached to an item, ratherfairly easy, it can be moved separately by the user. The camera also supports velocities (without friction) that are applied we just need to code the object based on timecollision detection. The Free Camera Class has the following Members:
* Getters** getPosition() multi- '''Returns a Vector Object that represents the position player network air hockey. Supports up to 8 players. Create an arena based on number of the Camera'''** getUp() - '''Returns players . Each wall has a Vector Object that represents the orientation of Up'''** getDir() - '''Returns hole and a Vector Object paddle that players can move left and right. A ball is the direction the camera is facing'''** getLeft() - '''Returns randomly sent flying and each time it goes through a Vector Object that represents hole, the orientation of Left'''** getLinearVel() - '''Returns player loses a Vector that is the velocity point. Lose 10 points and that the camera player is traveling at'''** getAngularVel() - '''Returns a Vector that contains the rotation velocity around the local (x, y, z) axis of the camera'''eliminated.

This function updates the position and rotation based on the set velocities''' == World Objects ==<br /> === Shape Class ====== Primitive Class ====== Model Class === == TO DO ==* get a website (in progress)* find out about exposing of open gl 1.1 calls*:* Should the OpenGL 1.1 calls Effects can be exposed used to change what material the Canvas3D web2.0 architecture. Mainly, for those functions that make 3D math easy (ie. gluLookAtpieces and board use such as metal, glMatrixModewood, etc).<br />  == Ideas List == Here are the wishlist of things we want :* Picking can be used to be able allow a simple interface to do with move the librarypieces.... If you want something add it to the list * 3D Asteroids - Good use of Collision detection, animation, particles, camera work, both mouse Either clicking on two tiles can move a piece or clicking on a piece and keyboard controls. * Solar System Explorer - Pull then a tile can move the positions of our planets from some sort of webservice and display them, allowing users to see their relative alignmentpiece* Simulation of 3D path finding * 3D graphs- Display social networks and their relationships<br />:* Further research is needed to determine the best server- Get earthquake Richter-scale values from a service and show graphs on a mapside language to use to share board state between players.<br />- Display 3D graphs beside one another, gas prices along stock market values:* Animation can be achieved simply by setting velocities of pieces.<br />
