| |
- | * Returns the Perlin noise value at specified coordinates. Perlin noise is a random sequence
| |
- | * generator producing a more natural ordered, harmonic succession of numbers compared to the
| |
- | * standard random() function. It was invented by Ken Perlin in the 1980s and been used since
| |
- | * in graphical applications to produce procedural textures, natural motion, shapes, terrains etc.
| |
- | * The main difference to the random() function is that Perlin noise is defined in an infinite
| |
- | * n-dimensional space where each pair of coordinates corresponds to a fixed semi-random value
| |
- | * (fixed only for the lifespan of the program). The resulting value will always be between 0.0
| |
- | * and 1.0. Processing can compute 1D, 2D and 3D noise, depending on the number of coordinates
| |
- | * given. The noise value can be animated by moving through the noise space as demonstrated in
| |
- | * the example above. The 2nd and 3rd dimension can also be interpreted as time.
| |
- | * The actual noise is structured similar to an audio signal, in respect to the function's use
| |
- | * of frequencies. Similar to the concept of harmonics in physics, perlin noise is computed over
| |
- | * several octaves which are added together for the final result.
| |
- | * Another way to adjust the character of the resulting sequence is the scale of the input
| |
- | * coordinates. As the function works within an infinite space the value of the coordinates
| |
- | * doesn't matter as such, only the distance between successive coordinates does (eg. when using
| |
- | * noise() within a loop). As a general rule the smaller the difference between coordinates, the
| |
- | * smoother the resulting noise sequence will be. Steps of 0.005-0.03 work best for most applications,
| |
- | * but this will differ depending on use.

- | * The functions are useful if you want to more control over camera movement, however for most users, the <b>camera()</b>
| |
- | * function will be sufficient.<br /><br />The camera functions will replace any transformations (such as <b>rotate()</b>
| |
- | * or <b>translate()</b>) that occur before them in <b>draw()</b>, but they will not automatically replace the camera
| |
- | * transform itself. For this reason, camera functions should be placed at the beginning of <b>draw()</b> (so that
| |
- | * transformations happen afterwards), and the <b>camera()</b> function can be used after <b>beginCamera()</b> if
| |
- | * you want to reset the camera before applying transformations.<br /><br />This function sets the matrix mode to the
| |
- | * camera matrix so calls such as <b>translate()</b>, <b>rotate()</b>, applyMatrix() and resetMatrix() affect the camera.
| |
- | * <b>beginCamera()</b> should always be used with a following <b>endCamera()</b> and pairs of <b>beginCamera()</b> and
| |
- | * <b>endCamera()</b> cannot be nested.

| |
- | * implemented in a consistent manner across renderers. Many options will often graduate to standard features
| |
- | * instead of hints over time.
| |
- | * hint(ENABLE_OPENGL_4X_SMOOTH) - Enable 4x anti-aliasing for OpenGL. This can help force anti-aliasing if
| |
- | * it has not been enabled by the user. On some graphics cards, this can also be set by the graphics driver's
| |
- | * control panel, however not all cards make this available. This hint must be called immediately after the
| |
- | * size() command because it resets the renderer, obliterating any settings and anything drawn (and like size(),
| |
- | * re-running the code that came before it again).
| |
- | * hint(DISABLE_OPENGL_2X_SMOOTH) - In Processing 1.0, Processing always enables 2x smoothing when the OpenGL
| |
- | * renderer is used. This hint disables the default 2x smoothing and returns the smoothing behavior found in
| |
- | * earlier releases, where smooth() and noSmooth() could be used to enable and disable smoothing, though the
| |
- | * quality was inferior.
| |
- | * hint(ENABLE_NATIVE_FONTS) - Use the native version fonts when they are installed, rather than the bitmapped
| |
- | * version from a .vlw file. This is useful with the JAVA2D renderer setting, as it will improve font rendering
| |
- | * speed. This is not enabled by default, because it can be misleading while testing because the type will look
| |
- | * great on your machine (because you have the font installed) but lousy on others' machines if the identical
| |
- | * font is unavailable. This option can only be set per-sketch, and must be called before any use of textFont().
| |
- | * hint(DISABLE_DEPTH_TEST) - Disable the zbuffer, allowing you to draw on top of everything at will. When depth
| |
- | * testing is disabled, items will be drawn to the screen sequentially, like a painting. This hint is most often
| |
- | * used to draw in 3D, then draw in 2D on top of it (for instance, to draw GUI controls in 2D on top of a 3D
| |
- | * interface). Starting in release 0149, this will also clear the depth buffer. Restore the default with
| |
- | * hint(ENABLE_DEPTH_TEST), but note that with the depth buffer cleared, any 3D drawing that happens later in
| |
- | * draw() will ignore existing shapes on the screen.
| |
- | * hint(ENABLE_DEPTH_SORT) - Enable primitive z-sorting of triangles and lines in P3D and OPENGL. This can slow
| |
- | * performance considerably, and the algorithm is not yet perfect. Restore the default with hint(DISABLE_DEPTH_SORT).
| |
- | * hint(DISABLE_OPENGL_ERROR_REPORT) - Speeds up the OPENGL renderer setting by not checking for errors while
| |
- | * running. Undo with hint(ENABLE_OPENGL_ERROR_REPORT).
| |
- | * As of release 0149, unhint() has been removed in favor of adding additional ENABLE/DISABLE constants to reset
| |
- | * the default behavior. This prevents the double negatives, and also reinforces which hints can be enabled or disabled.

- | * The tint() function sets the fill value for displaying images. Images can be tinted to
| |
- | * specified colors or made transparent by setting the alpha.
| |
- | * <br><br>To make an image transparent, but not change it's color,
| |
- | * use white as the tint color and specify an alpha value. For instance,
| |
- | * tint(255, 128) will make an image 50% transparent (unless
| |
- | * <b>colorMode()</b> has been used).
| |
- | *
| |
- | * <br><br>When using hexadecimal notation to specify a color, use "#" or
| |
- | * "0x" before the values (e.g. #CCFFAA, 0xFFCCFFAA). The # syntax uses six
| |
- | * digits to specify a color (the way colors are specified in HTML and CSS).
| |
- | * When using the hexadecimal notation starting with "0x", the hexadecimal
| |
- | * value must be specified with eight characters; the first two characters
| |
- | * define the alpha component and the remainder the red, green, and blue
| |
- | * components.
| |
- | * <br><br>The value for the parameter "gray" must be less than or equal
| |
- | * to the current maximum value as specified by <b>colorMode()</b>.
| |
- | * The default maximum value is 255.
