== 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.

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.

* Getters** getMatrix() - '''Returns an array Simulation of 16 numbers. Each value represents a location of the matrix starting at the top left corner (Row-Major)'''3D path finding
* Setters3D graphs:*Display social networks and their relationships<br />:* setMatrix(newMatArray) Get earthquake Richter- '''Takes an Array of 16 numbers that represent the matrix in Row-Major format'''scale values from a service and show graphs on a map<br />:* Display 3D graphs beside one another, gas prices along stock market values<br />:* 3D flowcharts<br />
* Calculations** identity() 3D Traceroute - '''Sets the matrix up to be an identity matrix'''** transpose() - ''' Transposes the matrix to be in Column-Major format, and vice versa'''** inverse() - '''Calculates the Inverse graphical view of the matrix. Returns NULL if it fails, else it returns an inverse matrix'''** determinant() - ''IP'Returns a number that is s path across the Matrices determinant'''** adjoint() - '''Returns the Hermitian transpose (Adjoint) of this matrix'''** multiplyByScalar(scalar) - '''Multiplies the values of the matrix by a number'''** divideByScalar(scalar) - '''Divides the values of the matrix by a number'''** multiplyByMatrix(mat) - '''Multiplies two matrices togetherinternet. It returns a new matrix'''** multiplyByVector(vec) - '''Mutiplies the orientation of the matrix by the vectorMore details [http://www. This function returns the newly oriented Vector'''** addMatrix(mat) - '''Adds the values of two matrices togetherc3dl. It returns a new matrix'''** subtractMatrix(mat) - '''Subtracts the values of the two matricesorg/index. It return a new matrix''' === Quaternion Class ===A Quaternion is a 4php/uncategorized/canvas3d-Dimensional representation of an orientation. It consists of a unittraceroute-length axis and an angle around that axis. It can function much like an orientation matrix but without the disadvantage of Gimble Lock. The Quaternion is stored as an array of 4 numbers, represented idea/ in the order of (w, x, y, z). The Quaternion Class has the following members: * Getters** getW() - '''Returns the numerical W component of the Quaternion'''** getX() - '''Returns the numerical X component of the Quaternion'''** getY() - '''Returns the numerical Y component of the Quaternion'''** getZ() - '''Returns the numerical Z component of the Quaternion'''** getMatrix() - '''Returns a Matrix object that reflects the orientation of the quaternion'''** getAxisAngle(axis, angle) - '''Takes in two values, a Vector object and a Number. Converts the orientation of the quaternion into an axis Vector and an angle around it'''this blog post]
* Setters** setFromQuat(quat) 3D Canvas Racing Demo - like [http://www.tapper- '''Sets ware.net/canvas3d/ this Quaternion with the same value as the one being passed in] but better, to show that it'''** setFromMatrixs both easier to use, more functionality is available, and runs much faster (mathopefully) - '''Creates a Quaternion orientation from the orientation of the Matrix object that is passed in'''
* Calculations** length() Molecule Viewer - '''Returns the length of the Quaternion'''** lengthSq() - '''Returns a number that represents the square of this Quaternion's length'''** addQuat(quat) - '''Takes a Quaternion object that will be added Rotate 3D molecules. Similar to [http://www.worldofmolecules.com/3D/bcarotene_3d.htm this Quaternion's internal (w, x, y, z) values'''** subtractQuat(quat) - '''Takes a Quaternion object where its values will be subtracted from this Quaternion's (w, x, y, z) values'''** multiplQuat(scalar) - '''Takes a number and multiplies its values by the Quaternion's (w, x, y, z) values'''** conjugate() - '''Returns a Quaternion that is this Quaternion's conjugate'''** dot(quat) - '''Takes a Quaternion and returns the Dot Product of the two'''** normalize() - '''Normalizes the quaternion'''** inverse() - '''Returns the inverse of this Quaternion''']
* Getters** getPosition() - '''Returns a Vector Object that represents the position Really fancy animation of the Camera'''** getUp() - '''Returns a Vector Object that represents the orientation of Up''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]** getDir() - '''Returns a Vector Object that is the direction the camera is facing'''** getLeft() - '''Returns a Vector Object that represents the orientation of Left'''** getLinearVel() - '''Returns a Vector that is the velocity that the camera is traveling at'''** getAngularVel() - '''Returns a Vector that contains the rotation velocity around the local (x, y, z) axis of the camera'''[[Image:higherhigher.jpg]]
* Setters** setPosition(vec) - '''Takes a Vector Generic model viewer application, with back/forward/index + zoom/rotate buttons that sets would download and display models from the camera's position'''** setLookAtPoint(vec) - '''Takes web. Would have to be able to convert 3dsmax models in JS. So a Vector that represents museum or such could just slap the point app on the camera will look at'''** setUpVector(vec) - '''Takes a vector that orients page and give it an array of URLs for the camera Up'''** setLinearVel(vec) - ''' Takes a vector that is the camera's linear velocity'''** setAngularVec(vec) - '''Takes a vector that represents the camera's rotational velocity around local (x, y, z) axis'''stuff to show.
* Other Functions** rotateOnAxis(axisPong. Should be fairly easy, angle) - '''Takes a vector and a number that represents a relative rotation we just need to code the camera's orientation'''** yaw(angle) - '''Takes a number that the camera will rotate around its Up vector'''** roll(angle) - '''Takes a number that the camera will rotate around its direction vector'''** pitch(angle) - '''Takes a number that the camera will rotate around its Left vector'''** update(timeElapsed) - '''Takes a number that represents the amount of milliseconds that passed since the last call to updatecollision detection. This function updates the position and rotation based on the set velocities'''
* 3D Canvas Racing Demo - like [http2 Player Online Chess:* Orbit camera can be used to orbit around the board.<br />:* Effects can be used to change what material the pieces and board use such as metal, wood, etc.<br /www>:* Picking can be used to allow a simple interface to move the pieces.tapper-wareEither clicking on two tiles can move a piece or clicking on a piece and then a tile can move the piece.net<br /canvas3d/ this] but better, >:* Further research is needed to show that it's both easier determine the best server-side language to use, more funcionality is available, and runs much faster (hopefully)to share board state between players.<br />:* Animation can be achieved simply by setting velocities of pieces.<br />
