Raw Blame History

X properly swap alpha values when lines need to be rendered backwards
X make cursor() commands public
X ltext and rtext for screen space stuff
X ltext is broken when it goes y < 0 or y > height
X ltext & rtext completely working
X make sure font creator is making fonts properly fixed width
X probably not using java charwidth for the char's width
X probably wasn't using textFont() properly
X now that it's actually a key, should it be a char? (what's keyChar?)
X that way println(c) would work a little better..
X libraryCalls() not properly working for pre, post, or draw()
o image(myg, x, y) doesn't work but image(myg, x, y, w, h) does
o (image kind prolly not set right and so image() gets pissy)
o http://processing.org/discourse/yabb/YaBB.cgi?board=Proce55ing_software_bugs;action=display;num=1091798655
text fixes
X make text rect use rectMode for placement
X if a word (no spaces) is too long to fit, insert a 'space'
X move left/center/right aligning into the font class
X otherwise text with alignment has problems with returns
X could PFont2 be done entirely with reflection?
X that way other font types can properly extend PFont
o font char widths from orator were not fixed width
o may just need to regenerate. if not, widths may be set wrong.
_ depth testing of lines vs text is problematic
_ use depth()/noDepth() to handle depth test
_ y2 position of rectangles not same as y2 position of lines
text issues
_ need to resolve SCREEN_SPACE vs OBJECT_SPACE
_ how does rotated text work?
_ PFont.rotate(180) rotate(PI)
_ does the font or PApplet control the size? (the font, ala java)
_ without setting the font, SCREEN_SPACE comes out weird
_ move SCREEN_SPACE into ScreenFont() class?
_ probably not, casey thinks screen space text is prolly more useful
_ that way can clear up some of the general confusion in the code
text wish list
_ look into fixing the texture mapping to not squash fonts
_ NEW_GRAPHICS totally smashes everything
_ not having kerning really blows
_ could this be pulled from the OpenType font stuff?
_ it could be placed at the end of the file
_ simple way to just use java text in p5 applets?
_ the current text support is just so hokey
_ before graphics engine change, attach jogl stuff
_ need to try jogl to make sure no further changes
_ and the illustrator stuff
_ 404 error because first searches applet directory on zipdecode
_ image(String name) and textFont(String name)
_ do we change to font(arial, 12) ?
_ write PApplet2, a full screen version of PApplet
_ this might be used for presentation mode
_ massive graphics engine changes
_ explicitly state depth()/nodepth()
_ move to new graphics engine
_ test with rgb cube, shut off smoothing
_ make sure line artifacts are because of smoothing
_ implement 2x oversampling for anti-aliasing
_ api for file-based renderers
_ need to work this out since it will affect other api changes
_ size(0, 0) and then ai.size(10000, 20000)
_ size 0 is code for internal to not show any window
_ saveFrame(PRenderer) or saveFrame("name", PRenderer)
_ saveFrame gets called at the beginning of loop()
_ or is just a message to save the next frame (problem for anim)
_ illustrator export / rendering mode
_ also postscript or pdf export?
_ update illustrator code to use core api
_ even if not actually working properly.. just in naming of things
_ sorting of polygons/lines on simple painters algorithm
_ better lighting model to show darkness at various depths
_ maybe just ultra-high res bitmaps from gl
_ version of BApplet that replaces g. with ai. or pdf.
_ figure out how to handle cached images, multiple images
_ MediaTracker blocking is prolly making jar download really slow
_ http://processing.org/discourse/yabb/YaBB.cgi?board=Proce55ing_software_bugs;action=display;num=1089914280;start=0
_ mkoser wish list
_ filled polygons working with smooth()
_ z-clipping
_ light(x, y, z, c1, c2, c3, TYPE)
_ also BLight with same constructor, and on() and off() fxn

b _ Lightest, Subtract, Darkest, Lighten, Darken
b _ flash:
b _ DIFFERENCE: C = abs(A-B);
b _ MULTIPLY: C = (A * B ) / 255
b _ SCREEN: C= 255 - ( (255-A) * (255-B) / 255 )

1 _ better lockout inside beginShape() to keep other things from happening
1 _ is quad strip broken or not behaving as expected?
1 _ may be correct, it worked for nik
1 _ inside draw() mode, delay() does nothing
1 _ delay might be a good way to signal drawing to the screen/updating
1 _ catch security exceptions around applet i/o calls
1 _ not just for saving files, but provide better error msgs when
1 _ attempting to download from another server
1 _ array utilities on Object[] are worthless.. fix it with reflection?
1 _ see if reflection will allow expand for all class types

1 _ text() with alignment doesn't work for multiple lines
1 _ don't change the size of a font when in screen space mode
1 _ patch rotated text (from visualclusto) into bfont
1 _ what sort of api? textSpace(ROTATED) ?
1 _ rotated text has a bug for when it goes offscreen
CORE / New Graphics
What the hell do we do with this code?
1 _ stroke not set on flat_rect
1 _ when drawing fonts w/ sami's code, left edge has problem
1 _ 8-bit (alpha) textures not blending
1 _ near-plane clipping currently disabled for triangles, enabled for lines
1 _ (but culling offscreen triangles works.. but may have been
1 _ commented out by carlos)
1 _ hint(NEW_GRAPHICS) needs to be called before allocate()
1 _ otherwise stencil buffer and 'triangle' object are null on first run
