Changes

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.

=== Scene Class =Related Resources ==* IN PROGRESS[http://www.khronos.org/webgl/ Khronos WebGL]

== 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:

* Calculations** normalize() - '''Unit Normalization'''** dot() - '''Calculates Here are the Dot Product. Returns a number'''** length() - '''Returns the Length wishlist of Vector from (0, 0, 0)'''** lengthSq() - '''Returns things we want to be able to do with the Squared value of Length'''** cross(vec) - '''Takes a Vector object and computes the Cross Product between the two valueslibrary.... Returns a Vector object that is the cross of the two'''** If you want something 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)the list. It returns a new Vector orientation'''

=== Matrix Class ===A Matrix Class is necessary to provide Matrix operations such as rotation, translation, and scaling to any point in * Solar System Explorer - Pull the 3D world. It is composed positions of a 4x4 matrix our planets from some sort of floating point values that can be applied webservice and display them, allowing users to any Matrix operationsee their relative alignment. This matrix is stored in '''Row-Major''' format, meaning its first 4 values are in the first row. The Matrix Class has the following members:

* 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

* Setters** setMatrix(newMatArray) - '''Takes an Array of 16 numbers that represent the matrix in Row-Major format'''3D graphs:* Calculations** identity() - '''Sets the matrix up to be an identity matrix'''** transpose() - ''' Transposes the matrix to be in Column-Major format, Display social networks and vice versa'''their relationships<br />:** inverse() - '''Calculates the Inverse of the matrix. 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) Get earthquake Richter- '''Multiplies the scale values of the matrix by from a number'''** divideByScalar(scalar) - '''Divides the values of the matrix by a number'''** multiplyByMatrix(mat) - '''Multiplies two matrices together. It returns service and show graphs on a new matrix'''** multiplyByVector(vec) - '''Mutiplies the orientation of the matrix by the vector. This function returns the newly oriented Vector'''map<br />** addMatrix(mat) - '''Adds the values of two matrices together. It returns a new matrix'''** subtractMatrix(mat) - '''Subtracts the values of the two matrices. It return a new matrix'''  === Quaternion Class ===A Quaternion is a 4-Dimensional representation of an orientation. It consists of a unit-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 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(axisDisplay 3D graphs beside one another, angle) - '''Takes in two gas prices along stock market values, a Vector object and a Number. Converts the orientation of the quaternion into an axis Vector and an angle around it''' * Setters** setFromQuat(quat) - '''Sets this Quaternion with the same value as the one being passed in'''<br />:** setFromMatrix(mat) - '''Creates a Quaternion orientation from the orientation of the Matrix object that is passed in'''3D flowcharts<br />

It cannot be attached allow users to an item, rather, it can be moved separately by navigate through the userenvironment or design a room in a house. The camera also supports velocities (without friction) that are applied to the object based on time. The Free Camera Class has the following Members:

* Other Functions** rotateOnAxis(axisReally fancy animation of a bar graph, angle) - '''Takes a vector with columns growing and a number that represents a relative rotation to the cameraarrow moving. Will be an instant hit with business people. Usable as easy as [http://code.google.com/apis/chart/ google's orientation'''** yaw(angle) - '''Takes a number that the camera will rotate around its Up vector'''toy]** 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 update[[Image:higherhigher. This function updates the position and rotation based on the set velocities'''jpg]]

== TO DO ==* get a website (in progress)* find out about exposing multi-player network air hockey. Supports up to 8 players. Create an arena based on number of open gl 1players .1 calls** Should the OpenGL 1 Each wall has a hole and a paddle that players can move left and right.1 calls be exposed to A ball is randomly sent flying and each time it goes through a hole, the Canvas3D web2player loses a point.0 architecture. Mainly, for those functions Lose 10 points and that make 3D math easy (ieplayer is eliminated. gluLookAt, glMatrixMode, etc) Last person alive wins.

== 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 * 3D Asteroids - Good use of Collision detection, animation, particles, camera work, both mouse and keyboard controls. * Solar System Explorer - Pull the positions of our planets from some sort of webservice and display them, allowing users to see their relative alignment. * Simulation of 3D path finding * 3D graphs * Display social networks and their relationships * Get earthquake Richter-scale values from a service and show graphs on a map * Display 3D graphs beside one another, gas prices along stock market values[[Category:Open Source Communities]]
