This THREEx helper provide various basic functions for THREE.Geometry.
It is able to scale, translate, center a geometry. Other functions may be
added soon.
The API is chained for convenience.



Scale



To make the geometry twice larger in y

THREEx.KeyboardState.js keep the current state of the keyboard.
It is possible to query it at any time. No need of an event.
This is particularly convenient in loop driven case, like in
3D demos or games.



Usage



Step 1: Create the object



var keyboard    = new THREEx.KeyboardState();



Step 2: Query the keyboard state



This will return true if shift and A are pressed, false otherwise



keyboard.pressed("shift+A")



Step 3: Stop listening to the keyboard



keyboard.destroy()



NOTE: this library may be nice as standaline. independant from three.js
- rename it keyboardForGame

This THREEx helper makes it easy to handle window resize.
It will update renderer and camera when window is resized.



Usage



Step 1: Start updating renderer and camera



var windowResize = THREEx.WindowResize(aRenderer, aCamera)



Step 2: Start updating renderer and camera



windowResize.stop()

Method:  tested each algorithm on 65^3 grid.  Plotted the function

  sin(omega * x) + sin(omega * y) + sin(omega * z)

in the range [-pi/2, pi/2] x [-pi/2, pi/2] x [-pi/2, pi/2]

To control for garbage collection and other unpredictable run time events, each run was repeated 100x to get an averaged measurement.

Also, since v8 has a JIT, we ran each method on a grid initialized with omega = 5 for 100 iterations in an attempt to trigger v8's optimizer.

Measurements were taken on my laptop:

  node.js version: 0.6.14
  Linux Mint 12
  CPU: Intel Core2 Duo P8700 @ 2.53GHz
  RAM: 4 GB

First column is omega, second column is time taken.  All measurements are in milliseconds (ms)

This THREEx helper provide various basic functions for THREE.Geometry.
It is able to scale, translate, center a geometry. Other functions may be
added soon.
The API is chained for convenience.



Scale



To make the geometry twice larger in y

THREEx.KeyboardState.js keep the current state of the keyboard.
It is possible to query it at any time. No need of an event.
This is particularly convenient in loop driven case, like in
3D demos or games.



Usage



Step 1: Create the object



var keyboard    = new THREEx.KeyboardState();



Step 2: Query the keyboard state



This will return true if shift and A are pressed, false otherwise



keyboard.pressed("shift+A")



Step 3: Stop listening to the keyboard



keyboard.destroy()



NOTE: this library may be nice as standaline. independant from three.js
- rename it keyboardForGame

This THREEx helper makes it easy to handle window resize.
It will update renderer and camera when window is resized.



Usage



Step 1: Start updating renderer and camera



var windowResize = THREEx.WindowResize(aRenderer, aCamera)



Step 2: Start updating renderer and camera



windowResize.stop()

This THREEx helper provide various basic functions for THREE.Geometry.
It is able to scale, translate, center a geometry. Other functions may be
added soon.
The API is chained for convenience.



Scale



To make the geometry twice larger in y

Translate



To make the geometry move 100 further in x
             		                            
             		           
                               
                            
                                
               

  var translation = new THREE.Vector3(100,0,0);
  THREEx.GeometryUtils.translate(geometry, translation);

             		                            
             		           
                               
                            
                                
               
Center



To center the geometry on its middle point
             		                            
             		           
                               
                            
                                
               

  THREEx.GeometryUtils.center(geometry);

THREEx.KeyboardState.js keep the current state of the keyboard.
It is possible to query it at any time. No need of an event.
This is particularly convenient in loop driven case, like in
3D demos or games.



Usage



Step 1: Create the object



var keyboard    = new THREEx.KeyboardState();



Step 2: Query the keyboard state



This will return true if shift and A are pressed, false otherwise



keyboard.pressed("shift+A")



Step 3: Stop listening to the keyboard



keyboard.destroy()



NOTE: this library may be nice as standaline. independant from three.js
- rename it keyboardForGame

This THREEx helper makes it easy to handle window resize.
It will update renderer and camera when window is resized.



Usage



Step 1: Start updating renderer and camera



var windowResize = THREEx.WindowResize(aRenderer, aCamera)



Step 2: Start updating renderer and camera



windowResize.stop()

/*
 * Signed integer types, yay team! A reminder on how two's complement actually
 * works. The first bit is the signed bit, i.e. tells us whether or not the
 * number should be positive or negative. If the two's complement value is
 * positive, then we're done, as it's equivalent to the unsigned representation.
 *
 * Now if the number is positive, you're pretty much done, you can just leverage
 * the unsigned translations and return those. Unfortunately, negative numbers
 * aren't quite that straightforward.
 *
 * At first glance, one might be inclined to use the traditional formula to
 * translate binary numbers between the positive and negative values in two's
 * complement. (Though it doesn't quite work for the most negative value)
 * Mainly:
 *  - invert all the bits
 *  - add one to the result
 *
 * Of course, this doesn't quite work in Javascript. Take for example the value
 * of -128. This could be represented in 16 bits (big-endian) as 0xff80. But of
 * course, Javascript will do the following:
 *
 * > ~0xff80
 * -65409
 *
 * Whoh there, Javascript, that's not quite right. But wait, according to
 * Javascript that's perfectly correct. When Javascript ends up seeing the
 * constant 0xff80, it has no notion that it is actually a signed number. It
 * assumes that we've input the unsigned value 0xff80. Thus, when it does the
 * binary negation, it casts it into a signed value, (positive 0xff80). Then
 * when you perform binary negation on that, it turns it into a negative number.
 *
 * Instead, we're going to have to use the following general formula, that works
 * in a rather Javascript friendly way. I'm glad we don't support this kind of
 * weird numbering scheme in the kernel.
 *
 * (BIT-MAX - (unsigned)val + 1) * -1
 *
 * The astute observer, may think that this doesn't make sense for 8-bit numbers
 * (really it isn't necessary for them). However, when you get 16-bit numbers,
 * you do. Let's go back to our prior example and see how this will look:
 *
 * (0xffff - 0xff80 + 1) * -1
 * (0x007f + 1) * -1
 * (0x0080) * -1

 *
 * What's happening above is really: 0xe0 & 0xff = 0xe0. However, the results of
 * this aren't treated as a signed number. Ultimately a bad thing.
 *
 * What we're going to want to do is basically create the unsigned equivalent of
 * our representation and pass that off to the wuint* functions. To do that
 * we're going to do the following:
 *
 *  - if the value is positive
 *      we can pass it directly off to the equivalent wuint
 *  - if the value is negative
 *      we do the following computation:
 *         mb + val + 1, where
 *         mb   is the maximum unsigned value in that byte size
 *         val  is the Javascript negative integer
 *
 *
 * As a concrete value, take -128. In signed 16 bits this would be 0xff80. If
 * you do out the computations:

Method:  tested each algorithm on 65^3 grid.  Plotted the function

  sin(omega * x) + sin(omega * y) + sin(omega * z)

in the range [-pi/2, pi/2] x [-pi/2, pi/2] x [-pi/2, pi/2]

To control for garbage collection and other unpredictable run time events, each run was repeated 100x to get an averaged measurement.

Also, since v8 has a JIT, we ran each method on a grid initialized with omega = 5 for 100 iterations in an attempt to trigger v8's optimizer.

Measurements were taken on my laptop:

  node.js version: 0.6.14
  Linux Mint 12
  CPU: Intel Core2 Duo P8700 @ 2.53GHz
  RAM: 4 GB

First column is omega, second column is time taken.  All measurements are in milliseconds (ms)

This THREEx helper provide various basic functions for THREE.Geometry.
It is able to scale, translate, center a geometry. Other functions may be
added soon.
The API is chained for convenience.



Scale



To make the geometry twice larger in y

Translate



To make the geometry move 100 further in x
             		                            
             		           
                               
                            
                                
               

  var translation = new THREE.Vector3(100,0,0);
  THREEx.GeometryUtils.translate(geometry, translation);

             		                            
             		           
                               
                            
                                
               
Center

THREEx.KeyboardState.js keep the current state of the keyboard.
It is possible to query it at any time. No need of an event.
This is particularly convenient in loop driven case, like in
3D demos or games.



Usage



Step 1: Create the object



var keyboard    = new THREEx.KeyboardState();



Step 2: Query the keyboard state



This will return true if shift and A are pressed, false otherwise



keyboard.pressed("shift+A")



Step 3: Stop listening to the keyboard



keyboard.destroy()



NOTE: this library may be nice as standaline. independant from three.js
- rename it keyboardForGame

This THREEx helper makes it easy to handle window resize.
It will update renderer and camera when window is resized.



Usage



Step 1: Start updating renderer and camera



var windowResize = THREEx.WindowResize(aRenderer, aCamera)



Step 2: Start updating renderer and camera



windowResize.stop()

This THREEx helper provide various basic functions for THREE.Geometry.
It is able to scale, translate, center a geometry. Other functions may be
added soon.
The API is chained for convenience.



Scale



To make the geometry twice larger in y

Translate



To make the geometry move 100 further in x
             		                            
             		           
                               
                            
                                
               

  var translation = new THREE.Vector3(100,0,0);
  THREEx.GeometryUtils.translate(geometry, translation);

THREEx.KeyboardState.js keep the current state of the keyboard.
It is possible to query it at any time. No need of an event.
This is particularly convenient in loop driven case, like in
3D demos or games.



Usage



Step 1: Create the object



var keyboard    = new THREEx.KeyboardState();



Step 2: Query the keyboard state



This will return true if shift and A are pressed, false otherwise



keyboard.pressed("shift+A")



Step 3: Stop listening to the keyboard



keyboard.destroy()



NOTE: this library may be nice as standaline. independant from three.js
- rename it keyboardForGame

This THREEx helper makes it easy to handle window resize.
It will update renderer and camera when window is resized.



Usage



Step 1: Start updating renderer and camera



var windowResize = THREEx.WindowResize(aRenderer, aCamera)



Step 2: Start updating renderer and camera



windowResize.stop()

This THREEx helper provide various basic functions for THREE.Geometry.
It is able to scale, translate, center a geometry. Other functions may be
added soon.
The API is chained for convenience.



Scale



To make the geometry twice larger in y

Translate



To make the geometry move 100 further in x
             		                            
             		           
                               
                            
                                
               

  var translation = new THREE.Vector3(100,0,0);
  THREEx.GeometryUtils.translate(geometry, translation);

             		                            
             		           
                               
                            
                                
               
Center



To center the geometry on its middle point
             		                            
             		           
                               
                            
                                
               

  THREEx.GeometryUtils.center(geometry);

THREEx.KeyboardState.js keep the current state of the keyboard.
It is possible to query it at any time. No need of an event.
This is particularly convenient in loop driven case, like in
3D demos or games.



Usage



Step 1: Create the object



var keyboard    = new THREEx.KeyboardState();



Step 2: Query the keyboard state



This will return true if shift and A are pressed, false otherwise



keyboard.pressed("shift+A")



Step 3: Stop listening to the keyboard



keyboard.destroy()



NOTE: this library may be nice as standaline. independant from three.js
- rename it keyboardForGame

This THREEx helper makes it easy to handle window resize.
It will update renderer and camera when window is resized.



Usage



Step 1: Start updating renderer and camera



var windowResize = THREEx.WindowResize(aRenderer, aCamera)



Step 2: Start updating renderer and camera



windowResize.stop()

This THREEx helper provide various basic functions for THREE.Geometry.
It is able to scale, translate, center a geometry. Other functions may be
added soon.
The API is chained for convenience.



Scale



To make the geometry twice larger in y

Translate



To make the geometry move 100 further in x

THREEx.KeyboardState.js keep the current state of the keyboard.
It is possible to query it at any time. No need of an event.
This is particularly convenient in loop driven case, like in
3D demos or games.



Usage



Step 1: Create the object



var keyboard    = new THREEx.KeyboardState();



Step 2: Query the keyboard state



This will return true if shift and A are pressed, false otherwise



keyboard.pressed("shift+A")



Step 3: Stop listening to the keyboard



keyboard.destroy()



NOTE: this library may be nice as standaline. independant from three.js
- rename it keyboardForGame

This THREEx helper makes it easy to handle window resize.
It will update renderer and camera when window is resized.



Usage



Step 1: Start updating renderer and camera



var windowResize = THREEx.WindowResize(aRenderer, aCamera)



Step 2: Start updating renderer and camera



windowResize.stop()

This THREEx helper provide various basic functions for THREE.Geometry.
It is able to scale, translate, center a geometry. Other functions may be
added soon.
The API is chained for convenience.



Scale



To make the geometry twice larger in y

Translate



To make the geometry move 100 further in x
             		                            
             		           
                               
                            
                                
               

  var translation = new THREE.Vector3(100,0,0);
  THREEx.GeometryUtils.translate(geometry, translation);

THREEx.KeyboardState.js keep the current state of the keyboard.
It is possible to query it at any time. No need of an event.
This is particularly convenient in loop driven case, like in
3D demos or games.



Usage



Step 1: Create the object



var keyboard    = new THREEx.KeyboardState();



Step 2: Query the keyboard state



This will return true if shift and A are pressed, false otherwise



keyboard.pressed("shift+A")



Step 3: Stop listening to the keyboard



keyboard.destroy()



NOTE: this library may be nice as standaline. independant from three.js
- rename it keyboardForGame

This THREEx helper makes it easy to handle window resize.
It will update renderer and camera when window is resized.



Usage



Step 1: Start updating renderer and camera



var windowResize = THREEx.WindowResize(aRenderer, aCamera)



Step 2: Start updating renderer and camera



windowResize.stop()
