-pdp_opengl (3dp): opengl extensions for pdp
-warning: this is still experimental and incomplete
-
-this library extends pdp with texture and render context packets, 
-to use some of the power of current video hardware.
-
-it is very much like gem (sort of a redesign, filled with my own
-idiosyncrasies). gem, like it is now, is not very suited for interaction 
-with pdp image processing because of its hardcoded window centric rendering, 
-so i thought i'd write some gem like stuff on top of pdp myself. (3dp right
-now only supports window centric rendering itself, but adding pbuffer
-or pixmap rendering is easy enough, though it requires a rather new glx
-library)
-
-so, 3dp is an experimental gem clone with tight pdp integration. unless 
-you like experiments, use gem, since it is better supported, has more 
-features and runs on linux, windows and mac osx.
-
-requires glx (opengl on x window).
-
-building:
-
-edit Makefile.config to reflect your system and run make. the library is
-pdp_opengl.pd_linux
-
-some of the examples use the abstractions in opengl/abstractions. best to
-add this to your pd path.
-
-
-there are some fatal X bugs floating around, so be careful with resizing
-windows and closing patches. there are a lot of other, non-fatal bugs
-or badly implemented features. if you have remarks, just let me know.
-
-
-i'll move to autoconf once i no longer consider it experimental. 
-
-
-TIPS & TRICKS
-
-
-* the 3dp_windowcontext creates a window to draw in. the window packet
-will be be output to the left outlet when a bang is received. control
-flow for context is right to left, this means if a 3dp object has 2
-context outlets, the rightmost will be propagated before the leftmost.
-there is no fanout. all operations are accumulative, including the
-geometric transformations. if you need to branch use a 3dp_push object.
-
-
-* geometric transformations can be done using the 3dp_view object.
-the first argument is the kind of transformation: scale, scalex,
-scaley, scalez, rotx, roty, rotz, rota, transx, transy, transz,
-transxyz.
-
-repectively this scales the object, the x, y, z axis, rotates 
-around the x, y, z axis, rotates around an arbitrary axis, translates
-in the x, y, z directions and translates along a vector. the initial
-parameters can be specified as creation arguments, i.e.:
-
-[3dp_view rota 1 1 1 90] rotates by 90 degrees around axis (1,1,1).
-
-
-* some simple objects can be drawn using the pdp_draw object. the
-first argument is the object: square, cube, sphere, torus, cone,
-teapot, dodeca, icosa, octa, tetra. prepending the names with a w
-draws the wireframe version. (i.e. wcube is a wireframe cube). the
-first inlet of the object is a texture inlet. not all objects support
-this, but cube, square and sphere do. other inlets set some parameters
-like size, nb of segments for sphere, etc.. they can be specified
-by creation arguments too.
-
-
-* saving a (matrix) state can be accomplished by the 3dp_push object.
-the default matrix is the modelview matrix. it works as follows: both
-the right and the left outlet propagate the same matrix state as the
-input. so in short you can use 3dp_push to split your rendering tree
-into parallel branches. the matrix types that can be pushed are:
-modelview, texture, color, projection.
-
-* setting a current matrix can be done using the 3dp_mode object.
-i.e. [3dp_mode texture] will map all geometric transforms to the
-texture matrix, for texture coordinate animation. the left outlet
-restores the current matrix back to the modelview matrix.
-
-* it is possible to send a render context trough a drawing/view
-transforming object multiple times. the easy way is to use 3dp_for,
-but other ways are legal too. this can be done to draw different
-versions of the same object. have a look at example01 how this can
-be done.
-
-it is also possible to send multiple render contexts trought the same 
-rendering tree (i.e. multiple windows). if you use different viewing 
-transformations on the top of the rendering chain, you can view a scene 
-trough different angles.
-
-
-* light sources can be introduces using 3dp_light. they can be moved
-with oridinary 3dp_view objects.
-
-
-* 3dp_color changes the current color. right outlet is new color,
-left outlet is the previous color.
-
-* 3dp_toggle toggles a boolean opengl switch. enabled now are:
-depth_test, blend_add, blend_mix. more to come later.
-
-
-
-* couping 3dp and pdp can be done using 3dp_snap and pdp_convert.
-the correct way to do it is to put 3dp_snap in a rendering
-chain and give it arguments like this:
-
-[3dp_snap image/*/* 320 240]
-
-if you specify the subtype to be image/multi/*, the packet
-will not be colour space converted: it will stay rgb.
-if you want to make a snapshot to store as a high quality
-png image, snap to bitmap/rgb/* and store it in pdp_reg to save.
-to convert an image back to a texture, use
-
-[pdp_convert texture/*/*]
-
-if you snap to a texture (which is the default)
-the dimensions don't need to be specified. a texture will be
-allocated that can contain the entire screen. this is because
-texture coordinates are relative and data is always interpolated.
-
-snapping only works correctly when the window is not covered
-by other windows.
-
-
-* textures can have any dimensions, but only those which have
-dimensions that are integral powers of two will be tiled correctly. 
-i.e. by using pdp_mode to change to texture mode and doing some
-coordinate transforms using pdp_view (see example06: this
-uses a tilable animated cellular automata texture)
-
-
-* multipass rendering is supported trough the objects
-3dp_subcontext, "3dp_draw clear" and "3dp_view reset". the idea
-is as follows: before rendering the final scene, you use
-(a part of) the drawing buffer to render some things and store
-them in a texture to be used in your final drawing pass. have
-a look at examples 11, 12 and 13. in theory you could build a
-"texture processing" framework on top of 3dp, by using the window
-buffer as an accumulator and using textures as auxilary registers,
-and drawing your final texture result using i.e. 
-3dp_display_texture. while this can be much faster than ordinary
-pdp image processing, it also requires you to do more bookkeping
-yourself, since you can only use a "serial" approach because
-you can't modify textures directly, only trough the use of the
-render buffer.
-
-
-* 3dp has it's own thread, which is enabled by default. you
-can enable/disable this by sending a "3dthread 0/1" message
-to pdp_control. in most cases there's no reason to disable
-the thread processing, except when you are doing a lot of
-pdp<->3dp conversions. in that case the delay introduced by
-the thread processing might become problematic. (the same
-goes for pdp btw. feedback and threads don't mix too well).
-it's a tradeoff. thread processing gives priority to the audio,
-so you can obtain low latency, and you don't have to care
-about locking up pd by doing too much processing. (instead
-frames will be dropped). the drawback is of course that video 
-timing becomes unpredictable because it is governed by the system
-scheduler. so sometimes it can be useful to disable threads
-and increase the audio latency, so you can have snappy audio
-and video at the same time. getting this to work well usually
-requires some experimenting.

-some political ranting: gem vs. pdp/3dp
-
-first a disclaimer. i'm not into dissing people. i respect and appreciate
-all the work that has gone into gem, but at the same time i'm not too happy
-with what gem has become. not so much the functionality, but the way it is
-built. the original design as a 3d processing extension is not flexible enough
-to incorporate what's in there now and what could be added in the future..
-
-instead of complaining about it, i decided to be pragmatic and write something 
-from scratch. i think, sometimes this has to be done. for me writing pdp/3dp 
-has been an extremely interesting learning experience. i think i understand 
-the trade-offs better now, and maybe these remarks can be useful.
-
-opengl is not a pure dataflow language. it operates on a global machine
-state next to the obvious drawing buffer that is passed around. 
-representing opengl code with a graphic tree view has some advantages, 
-though it has a different "feel" than normal pd patches. the fact that
-opengl transforms object coordinates to screen coordinates, and not vice
-versa, gives graphicly represented opengl code an "upside down" feel.
-
-one of the things i don't like about gem is that it has both the opengl 
-"upside down drawing and coordinate transformation tree" and the pix 
-"data flow image processing tree" in the same network, which i find 
-counterintuitive. it is too monolytic to be truly flexible. in pdp/3dp
-i try to separate the two explicitly: dataflow where possible (image
-processing), and serial context based processing where needed (opengl).
-
-another disadvantage of gem is its window centric context. by building
-3dp around explicit context passing, with explicit context creation objects,
-i try to avoid this. an advantage of this is the possibility to send
-multiple contexts trough a rendering tree, i.e. to have 2 different views
-of the same scene.
-
-pdp has implicit fanout for all packets. i think that is its great
-strength. it enables you to use any kind of media packet like you would
-use floats. it is very intuitive. however, 3d rendering does not fit
-this shoe. at least not when you just wrap opengl in the most straightforward
-way. 3dp is a test case for pdp's "accumulation packets", which is a formal
-abstraction of a context. pdp processors are noting more than serial programs
-working on a context, so in fact it's nothing special. in fact, i'm still
-in doubt if it is useful besides being able to support opengl..
-
-so, the idea was to improve upon gem a bit, from different angles. i did
-not succeed in my primary goal: making 3dp more intuitive than gem. it seems
-this is only possible if you limit some of the flexibility. just wrapping
-opengl keeps a lot of flexibility, but get's infected with the opengl
-paradigm. by separating pdp (image processing) and 3dp (drawing and geometry
-processing) as much as possible i think i've solved some intuition problems, 
-but 3dp itself is still basicly gem, with imho a better overall design,
-but due to its more low level approach, maybe harder to understand. it seems
-to me that knowing how opengl works is rather necessary to use 3dp. the same
-is true for gem.
-
-one last philo remark: to me it seems the biggest drawback of gem's design is
-the processor centric aproach: the only objects are processors, the data is 
-implicit and seemingly global. in pdp/3dp processors and objects are 2 separate
-entities. i tried to unify them in one object model, but to me it seems the two
-should really be treated as different complementary entities, to stay close to 
-the dataflow paradigm which makes pd such an intuitive tool.

-todo:
-
-* fix flow control for texture conversion
-* fix display event routing for multiple windows
-* finish mesh object
-
-
-general:
-
-* prevent display list recursion: add some state data to the context packet to solve this.
-
-redesign:
-* unify pbuf & window contexts (postponed pbufs because of subcontexts)
-* cube mapping
-* bubble object (model + wave equation)
-* finish 3dp light
-
-performance:
-* why is texture upload so slow? and is there a way to work around it?
-* (why) is context switching slow? and how to introduce the render context differently. (direct to window?)

-
-DESIGN NOTES
-
-3dp is basicly my idea of gem on top of pdp. it is a simple layer around opengl.
-3dp_* render and transform objects accept a reference to a rendering context and pass this along.
-
-3dp_* objects DO NOT SUPPORT FANOUT. they do support fanin. multiple contexts can be sent to an object, which 
-will result in drawing in (or other manipulations of) the respective contexts.
-
-texture packets can be used to pass bitmap data around. 3dp_tdraw accepts a texture on its
-second inlet. 3dp_snap dumps the current state of the buffer into a texture packet.
-
-object classes:
-
--drawing objects
-
-[3dp_draw cube] [3dp_draw sphere] ..
-
--manipulation objects
-
-[3dp_view rot2d]
-
--opengl stack objects
-
-[3dp_push color view texture]
-
-3dp vs pdp design:
-
-a context packet is an accumulation packet, and the order of operations on it (serial) is important. it has 
-elements from a readonly packet (only one instance is passed around) and from a rw packet (it is legal to change it's
-state and pass it on).
-
-opengl in dataflow formulation seems to be read bottom to top. i first thought
-this was a big drawback of gem, but now that i finally understand how opengl works i think it is
-ok. it suddenly dawned on me, usually the number of eyes is much smaller than the number of objects
-in a scene, so it is much more straghtforward to start at the eye instead of the objects. since a
-simple serial stack mechanism can be used.
-
-so opengl is really serial, while pd "looks" parallel, but is serial too. i still think this
-is a good thing, since it keeps things simple, but for some reason the "upside down & serial"
-thing about opengl in pd is rather strange..
-
-once you get used to it, and think about rendering a set as a tree rooted at the "context source"
-like is done in gem,it seems to work out..
-
-i think i'm going to stick to the depth first backtracking a tree serial rendering 
-way of looking at it. since i don't see a way of making this more intuitive without complicating
-it too much. so no legal fanout of a context packet.
-
-------------------
-
-accumulation packets (buckets) & backtracking
-
-buckets add support for "context based" single threaded programs. it
-basicly allows you to construct data processors represented as a control
-flow tree. i.e. function calls can be represented by branches in a tree,
-with each branch rooted at an object's outlet, executed from right to
-left. a "context packet" (or accumulation packet or bucket) is passed
-along and acted upon.
-
-* fanout is illegal for bucket processors (at least, if they are non
-cummutative, as is usually the case). this is not explicitly prohibited,
-since it is hard to check in pd and it allows some hacks. the reason for
-this is obvious: if you do not know which branch of a tree is executed
-first, results are undefined.
-
-* a new communication protocol needs to be introduced, incompatible
-with the existing 3 phase protocol:
-
-(1) register_ro
-(2) register_rw
-(3) process
-
-the new dpd (bucket / accumulation packet) protocol is 2 phase:
-(1) inspect
-(2) accumulate
-
-(1) is only present to give priority to bucket inspectors over
-accumulators (processors)
-
-an accumulation packet will be owned by its creator all the time.
-accumulation processors do not increase the reference count. only ro
-inspectors will.
-
-note: it is legal for a packet to have a broken register_rw (missing 
-copy constructor, i.e. if a copy is too expensive or impossible. this
-must be set in the pdp packet header flags by the packet constructor)
