== 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.
== Links ==[http://littlesvrAs of c3dl 2.0, our library uses WebGL. Any WebGL enabled browser will be able to view our content. To get a WebGL enabled browser see Tutorial 1 from our website and you do not need any addons.ca/canvas3d/blog/ Our blog]
== Prototype ==For all older versions of c3dl, you will need the canvas 3D addon available here:[httpYou can get the extension from https://img126addons.imageshackmozilla.usorg/en-US/firefox/img126addon/30327171 (use suckmenot@mailinator.com/layoutqe4bugmenot for authentication).jpg Canvas 3D API - Class Design]
== Examples ==* INCOMPLETENOTE: It is HIGHLY recommended that you do not use the older version of our library but to use version 2.0 or higher.

== Math Operations ==
==Documentation = Vector Class ===A Vector basically describes a direction in the form of X, Y, and Z coordinates of a 3D world. Basic 3D math cannot exist without the utilization of spatial coordinates which the Vector Class encapsulates. The Vector Class will have the following members within it:
* Getters** getX() - '''Retrieves the X value'''** getY() - '''Retrieves the Y value'''** getZ() - '''Retrieves the Z value'''Documentation can be found on our website: [http://www.c3dl.org/index.php/documentation/ c3DL.org].
* Setters
** set(newX, newY, newZ) - '''This sets new (x, y, z) values to the Vector'''
** setX(newX) - '''Takes a number value as the new value for X'''
** setY(newY) - '''Takes a number value as the new value for Y'''
** setZ(newZ) - '''Takes a number value as the new value for Z'''
** setFromVector(vec) - '''Takes a Vector object as the new value for this Vector'''
* Calculations** normalize() - '''Unit Normalization'''** dot() - '''Calculates the Dot Product. Returns a number'''** length() - '''Returns the Length of Vector from (0, 0, 0)'''** lengthSq() - '''Returns the Squared value of Length'''** cross(vec) - '''Takes a Vector object and computes the Cross Product between the two values. Returns a Vector object that is the cross of the two'''** add(vec) - '''Takes a Vector object and adds its values to its own'''** subtract(vec) - '''Takes a Vector object and subtracts its values from its own'''** multiply(scalar) - '''Takes a number value and multiplies (x, y, z) by it'''** divide(scalar) - '''Takes a number value and divides (x, y, z) by it'''** isEqual(vec) - '''Takes a Vector object and compares it to its (x, y, z) values. Returns true if they match'''** multiplyByQuat(quat) - '''Takes a Quaternion and multiplies its orientation by (x, y, z). It returns a new Vector orientation'''== Ideas List ==
Here are the wishlist of things we want to be able to do with the library.... If you want something add it to the list.
=== Matrix Class ===A Matrix Class is necessary to provide Matrix operations such as rotation* 3D Asteroids - Good use of Collision detection, animation, translationparticles, camera work, both mouse and scaling to any point in the 3D world. It is composed of a 4x4 matrix of floating point values that can be applied to any Matrix operation. This matrix is stored in '''Row-Major''' format, meaning its first 4 values are in the first rowkeyboard controls. The Matrix Class has the following members:
* Getters** getMatrix() Solar System Explorer - '''Returns an array Pull the positions of 16 numbersour planets from some sort of webservice and display them, allowing users to see their relative alignment. Each value represents a location of the matrix starting at the top left corner (Row-Major)'''
* Setters** setMatrix(newMatArray) - '''Takes an Array Simulation of 16 numbers that represent the matrix in Row-Major format'''3D path finding

Returns NULL if it fails, else it returns an inverse matrix'''** determinant() - '''Returns a number that is the Matrices determinant'''** adjoint() - '''Returns the Hermitian transpose (Adjoint) of this matrix'''** multiplyByScalar(scalar) - '''Multiplies the values of the matrix by a number'''their relationships<br />:** divideByScalar(scalar) Get earthquake Richter- '''Divides the scale values of the matrix by from a number'''** multiplyByMatrix(mat) - '''Multiplies two matrices together. It returns service and show graphs on a new matrix'''map<br />:** multiplyByVector(vec) - '''Mutiplies the orientation of the matrix by the vector. This function returns the newly oriented Vector'''** addMatrix(mat) - '''Adds the Display 3D graphs beside one another, gas prices along stock market values of two matrices together. It returns a new matrix'''<br />:** subtractMatrix(mat) - '''Subtracts the values of the two matrices. It return a new matrix'''3D flowcharts<br />

=== Quaternion Class ===A Quaternion is a 4* 3D Canvas Racing Demo -Dimensional representation of an orientationlike [http://www. It consists of a unittapper-length axis and an angle around that axisware. It can function much like an orientation matrix net/canvas3d/ this] but without the disadvantage of Gimble Lock. The Quaternion better, to show that it's both easier to use, more functionality is stored as an array of 4 numbersavailable, represented in the order of and runs much faster (w, x, y, zhopefully). The Quaternion Class has the following members:

=== Free Camera Class ===The Free Camera Class is a camera * Generic model viewer application, with back/forward/index + zoom/rotate buttons that can be translated would download and orienteddisplay models from the web. It cannot Would have to be attached able to convert 3dsmax models in JS. So a museum or such could just slap the app on the page and give it an item, rather, it can be moved separately by array of URLs for the user. The camera also supports velocities (without friction) that are applied stuff to the object based on timeshow. The Free Camera Class has the following Members:

Either clicking on two tiles can move a piece or clicking on a piece and then a number that tile can move the camera will rotate around its Left vector'''piece.<br />:** update(timeElapsed) Further research is needed to determine the best server- '''Takes a number that represents the amount of milliseconds that passed since the last call side language to use to updateshare board state between players. This function updates the position and rotation based on the set <br />:* Animation can be achieved simply by setting velocities'''of pieces.<br />
