Raw Blame History

0075
X textureMode(NORMAL_SPACE) screws up the image() command
X image() appears to require IMAGE_SPACE to function properly.
X added focusGained() and focusLost()
X lots of changes to internal naming of vars
X beginShape() defaults to beginShape(POLYGON)
_ needs to be noted for the reference
X screenX(x, y) and screenY(x, y) added for noDepth()
X add TRIANGLE_FAN
X eyeX, eyeY etc have been renamed cameraX/Y/Z, and cameraNear/Far
X modify targa and tiff writing routines to break into header writing
X writeTIFF, writeHeaderTIFF, writeTGA, writeHeaderTGA
X MAJOR CHANGE: RGBA becomes ARGB for accuracy
opengl
X why is the thing hanging until 'stop' is hit?
X what happens when stop is hit that sets it free?
X (at what point does it start working properly?)
X cache needs to also make things a power of 2
X if images are already a power of 2, then needn't re-alloc
X cacheIndex needs to be set to -1 when the image is modified
X or maybe have a modified() function?
X debug why certain spots are having errors (see 'problem here' notes)
X INVALID_OPERATION after drawing lines for cube
X fix noLoop bug
X remove errors when drawing textures
X reverse y coordinates
_ beginFrame() around setup()
_ draw mode stuff happens inside setup..
_ or maybe need to get better at size() inside of draw() ?
_ make this consistent with the regular PApplet
_ otherwise things are going to be weird/difficult for debugging
_ fix non-bound textures from mangling everything else
_ fix enable/disable textures for some objects
_ fix endian ordering issues so that things work properly
_ figure out min/max texture sizes when binding to avoid problems
_ minimum texture size may be 64x64
_ might need to enforce it as a minimum
_ remove need to use depth() at the beginning
_ and cameraMode(PERSPECTIVE) on each frame
_ why is the first one failing?
_ get loop, noLoop, redraw, and framerate all working
_ needs custom animator thread..
_ make play button un-highlight with opengl
_ also make window move messages work properly
_ very necessary, since opens window at 100x100
_ can ALPHA fonts work using the other replace modes?
_ resolve ARGB versus RGBA versus just A issues for fonts
_ make sure that current scenario works identically on mac
_ if so, just switch the image code to expect alpha in the high bits
_ fonts probably need to be RGBA, not ALPHA style images
_ there's nothing really ALPHA about them?
_ implement fullscreen().. this takes over the screen as best it can
_ really more like present mode..
_ that if applet is 500x500, centers on a 800x600 window
_ though how do you get the screen size?
_ screen.width and screen.height?
_ image(String name) and textFont(String name)
_ do we change to font(arial, 12) ?
scripting
_ on exceptions, use die to just kill the applet
_ make the file i/o stuff work more cleanly
_ if people want to use their own file i/o they can do that too
_ how to make a long setup() sleep so that things don't lock way up
_ this could also be contributing to the hanging bug
_ make properly exit after things are finished
_ static applets need to be able to resize themselves on 'play'
_ figure out what to do with static apps exported as application
_ needs to just hang there
_ scripts (w/ no graphics) will need to call exit() explicitly
_ actually.. just override the default draw() to say exit()
_ may need a fileOutput() and fileInput() function
_ to take care of exception handling
_ or maybe scripts are just handled with a different method? (yech)
_ or maybe setup() can actually throw and Exception?
_ but that's inserted by the parser, and hidden from the user?
_ implement size(0, 0) -> just doesn't bother doing a frame.show();
_ too abstract, just have draw() call exit by default
_ so if nothing inside draw, just quits
opengl documentation
_ lights cannot be enabled/disabled throughout
_ lighting will be based on what's left at endFrame()
_ images should be a power of 2, or call modified()
_ need to make sure that components can be resized properly via size()
_ or that it properly responds to a setBounds() call
_ also when drawing an image, sense whether drawn rotated
_ if just rotate/translate, then can use SCREEN_SPACE for fonts
_ bring screen space and font size settings back in to PGraphics
_ causing too much trouble to be stuck down in PFont
_ don't allocate zbuffer & stencil until depth() is called
_ 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
_ before graphics engine change, attach jogl stuff
_ need to try jogl to make sure no further changes
_ and the illustrator stuff
postscript
_ how to hook into curve rendering so that curve segments are drawn
_ maybe lines are rendered and sorted,
_ but they point to an original version of the curve geometry
_ that can be re-rendered
_ also integrate catmull-rom -> bezier inverse matrices
_ even with the general catmull-rom, to render via ai beziers
libraries
_ libraries could handle a series of events..
_ i.e. a 'completion' event, or 'new data' event
_ these could be registered on obejcts in a general way
random tasks
_ someone to figure out a good model for adaptive sizing of circles
_ also goes for arcs, though will be weighted based on arc size
_ figure out why tiff images won't open with after effects
_ open with photoshop, resave, see which tags change
_ particularly of those that are included in the original image
_ perhaps something gets corrected?
_ arc with stroke only draws the arc shape itself
_ may need a 'wedge' function to draw a stroke around the whole thing
_ how to handle full screen (opengl especially) or no screen (for scripts)
_ image loading bug is huge
_ pmouseX is broken again
_ maintain things a bit different
_ email the beta@ list to see how people are using pmouseX
_ need timer in as part of the api
_ or at least include an example that uses it
_ depth testing of lines vs text is problematic
_ probably need to patch in an older version of the line code
_ use depth()/noDepth() to handle depth test
_ y2 position of rectangles not same as y2 position of lines
_ happens when the rectangle is flipped on the x or y axis
_ probably a hack that draws the "last" point differently
_ fishwick bug with text() and shapes
_ ellipses no longer completed when g.dimensions = 2 or 3,
_ or not even drawn.. what a mess.
_ only allocate stencil and zbuffer on first call to depth()
_ this will require changes to PTriangle and PLine inside their loops
_ break apart functions into local (placement) and override (blitting)
_ just have a "thin_flat_line" option in opengl code
_ image("blah.jpg");
_ loadImage() is broken on some machines
_ hacked for a fix in 72, but need to better coordinate with openStream()
_ uv coords > 1 shouldn't clamp, they should just repeat ala opengl
_ actually i think opengl has a setting for it
_ renderers can plug in:
_ at direct api level
_ taking over all color() functions and vertex collection
_ at endShape() level
_ where vertices are collected by core and blit on endShape()
_ (takes polygons and lines)
_ at post tesselation level
_ takes only line segments and triangles to blit (dxf writer)
_ vertices max out at 512.. make it grow
_ go through and figure out what stuff to make public
_ screenX/Y aren't properly working for 2D points against a 3D matrix
_ (ryan alexander rounding bug)
_ Just to clarify, it works completely correctly with rounding
_ screenX/Y and also using the 3 arg version of translate -
_ ie translate(hw,hh,0) instead of just translate(hw,hh).
text issues
_ text() with \n is semi-broken
_ font encoding issues
_ java seems to force straight windows encoding.. (problem for pi fonts)
_ opentype/cff fonts don't work with live loading from the app
_ many (all?) opentype fonts won't show up or aren't supported
_ this may be only cff fonts that have trouble
_ when encoding with something besides the standard encoding, problematic
_ so sonata otf and sonata don't seem to have any chars at all
_ getAllFonts() not quite working for many fonts
_ i.e. Orator Std on windows.. macosx seems to be ok
_ is getFamilyNames() any different/better?
_ when did this break? 1.4.1? 1.4.x vs 1.3?
_ may be that cff fonts won't work?
_ textMode ALIGN_CENTER _LEFT _RIGHT -> CENTER, LEFT, RIGHT ?
_ need to resolve SCREEN_SPACE vs OBJECT_SPACE
_ can this be auto-detected with noDepth()?
_ how does rotated text work?
_ PFont.rotate(180) rotate(PI)
_ or can this be detected from the matrix?
_ 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
_ check into symbol font encoding with create font
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
_ named colors.. have a method for a full color lookup table
_ addcolor("blah blah blah", colornum);
_ fill("blah blah blah");
_ maybe this is bad practice--too slow, should use variables
_ 404 error because first searches applet directory on zipdecode
_ write PApplet2, a full screen version of PApplet
_ this might be used for presentation mode
_ 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

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 _ hint(NEW_GRAPHICS) needs to be called before allocate()
1 _ otherwise stencil buffer and 'triangle' object are null on first run
