Release 60: Shark Attack
« on: Sep 23rd, 2003, 1:14am » |

release 60 is in the process of being uploaded and posted. it's a biggun.
....
IMPORTANT NOTE! ACHTUNG!
YOUR OLD CODE WILL PROBABLY BE BROKEN WITH THIS RELEASE.
read the section on api changes very carefully, because a few
functions have been renamed, and the behavior of background() has
changed completely. almost all programs will have to be updated.
but the happy part is that there are many many new features, and this
change to the behavior of background() means lots of positive things.
we decided to make as many of these naming changes as possible all at
once, so that you only have to really mess with your code a single
time. as casey put it, it's better to remove the band-aid quickly.
if you're confused, all the examples have been updated for this
release to use the new function names and background methods. a quick
glance through them should help clear things up.
[ api changes -- read carefully, avoid headaches ]
- noBackground() no longer exists, so remove it from your code.
- background() actually clears the screen immediately, rather than
simply setting a color. this means that you should use background()
a the beginning of loop(), if you want your applications to behave
similar to the way they used to.
- hint(SMOOTH_IMAGES) no longer exists, and is simply the default.
just remove it from your code. if you get an error saying:
"No field named "SMOOTH_IMAGES" was found in type "Temporary_NNNN_NNNN".
you should remove the line "hint(SMOOTH_IMAGES);" from your program.
SMOOTH_IMAGES is no longer needed and has been removed.
- fill() no longer colors images. if you want to color images, use
tint(), which is just like its cousins fill and stroke. like its
cousins, there's also noTint(), his (her?) contrarian twin.
- getPixel() -> get() and setPixel() -> set()
- get() and set() work directly on BImage objects.
- get(int x, int y, int width, int height) copies a section of pixels
and puts them in a BImage. (based on code from toxi)
- screenGrab() -> saveFrame()
saveFrame() will save a sequence of numbered tiff images
saveFrame("blah.tif") will save the current frame as blah.tif
saveFrame("blah-####.tif") will save a sequence of images
as blah-0000.tif, blah-0001.tif, etc.
saveFrame("blah.tga") will save the current frame as targa.
saveFrame("blah-####.tga") is up to you to figure out.
- strokeWidth() -> strokeWeight()
- bezier(a, b, c, d, t) -> bezierPoint(a, b, c, d, t);
curve(a, b, c, d, t) -> curvePoint(a, b, c, d, t);
- vertexTexture(u, v) has been rolled into vertex(), so:
vertex(x, y); vertexTexture(u, v); -> vertex(x, y, u, v);
vertex(x, y, z); vertexTexture(u, v); -> vertex(x, y, z, u, v);
- vertexNormal() -> normal()
- font.stringWidth(String s) -> font.width(String s)
font.charWidth(char c) -> font.width(char c)
- removed control key 'F' for 'reference', gave it to 'find'.
also set cmd-shift-f as 'find in reference'.

[ additions ]
- good god, an implementation of find & replace, which means we've
caught up to 1984.
- BImage.save(String filename) has been implemented. the filename
should be something and a .tif or .tga at the end to determine how
the file should be saved.
- background(BImage image); has been implemented, so your background
can automatically be replaced with an image. note that the image
must be the same size as your drawing area.
- BImage.copy() returns a copy of an image. better yet,
BImage.copy(int width, int height) returns a copy of an image, but
resized to that specific size. (code contributed by toxi)
- online() returns a true or false for whether an applet is online or
not. (or really, whether it's running in a proper applet viewer)
- status(String text) shows a string in a browser's status bar, or
sends it to the console in an application. (this replaces
Applet.showStatus if you're familiar with that)
- bezierTangent() now implemented, but curveTangent() is unfinished.
- param(String p) reads params from your html code for your applet.
- text(float something, float x, float y) and
text(int something, float x, float y) have been implemented.
just because their syntax is otherwise cumbersome.
- textMode(ALIGN_LEFT), textMode(ALIGN_CENTER), textMode(ALIGN_RIGHT)
are implemented, and do what you might expect them to.
- clean and pretty two dimensional circles and ellipses have been
implemented. this will speed and beautify your 2D elliptical needs.
- added several error messages to provide more useful feedback about
misuse of font api functions or common problems.
- added an error message (instead of failing silently) for when
noCursor() is attempted in an exported applet.
- BImage.blendMode() has been added, thanks to toxi. details and
examples are forthcoming.
- it is now possible to draw inside of setup().
- you are no longer restricted to using numbers (rather than
variables) for size() and background().
- BGraphics now subclasses BImage. if you don't know what that means,
don't worry about it. just trust me.

[ known problems, pardon our dust ]
- macosx doesn't provide an option to 'cancel' when it so politely asks
if you want to "save changes before quitting". this is because of
weirdness in apple's java that we're trying to straighten out.
- lines with stroke weights that aren't 1 are probably broken.
- single pixel lines still have some problems with drawing over things.
- the size of exported applets has jumped in this release. this will
get smaller again in a future release. we're in the middle of
transitioning between two different sets of rendering/graphics code.
- clipping planes are not yet implemented. meaning that objects may
sometimes fly into the camera and turn upside down or do other tricks.

http://proce55ing.net/discourse/yabb/board_Proce55ing_software__bugs_action_display_num_1052313604_start_0.html
http://proce55ing.net/discourse/yabb/board_Proce55ing_software__bugs_action_display_num_1042699742.html
- concave polygons still don't work, meaning that lots of irregular
polygons won't draw properly.
http://proce55ing.net/discourse/yabb/board_Proce55ing_software__bugs_action_display_num_1062469819_start_0.html
- jikes is ~9 megabytes in size, which is a bit obnoxious. it doesn't
hurt anything but we plan to put it on a diet for a future release.
http://proce55ing.net/discourse/yabb/board_Proce55ing_software__bugs_action_display_num_1062581723.html
- curveTangent() is not yet implemented. contributions welcome.
- strokeMiter() and strokeJoin() exist but are not implemented.
- textures warp in strange ways due to perspective problems.
http://proce55ing.net/discourse/yabb/board_Proce55ing_software__bugs_action_display_num_1050650262.html
- smooth() is not completely implemented. there will be quirks in how
it draws (like a weird flat line at the end of a shape, or areas
that are less than smooth).
- on windows, processing can't be run from a folder that has non-ascii
characters in its name.
http://proce55ing.net/discourse/yabb/board_Proce55ing_software__bugs_action_display_num_1062794781.html
- video examples sometimes crash the whole environment on windows
- net needs work, it's currently sending unicode, instead of ascii or
UTF-8, data. this can cause problems with other programs.
