Re: [ANN] 1st public release of thi.ng geometry toolkit (CLJ CLJS)
Thank you all for the kind words - I'm very chuffed and excited to develop this further! Sorry also for sluggish response - it's been a super busy week. Some combined responses below... @Malcolm - Since much of my work deals with creating visualizations of all sorts (not just data viz in the traditional sense), my mission for this project is very much about making these things easier the process of data/design exploration more fluid. Projects like Processing d3 are a great stepping stone in that direction as well and provide a much more direct route from pure data to graphic representation, but for me the main shortcoming of all those frameworks is their focus on pure drawing functionality, whereas geom is all about providing the underlying geometric models. Eg. Processing/Quil/OpenGL/WebGL etc. make it very easy to *draw* a line or other shape, but they have absolutely no concept of it and don't provide any functionality in order to meaningfully work with say a bunch of lines as entities, e.g. to find intersections, calculate a curve from them, turn it into a polygon, sort shapes by area or extrude them into a 3d object etc. I've been going on about this lack of models for a decade whilst using Processing and it too was the initial impetus for starting toxiclibs, the previous iteration of this new geom toolkit. I think, especially when dealing with data visualization, the presence of geometric models/entities representing the to-be-visualized data is of core essence and I don't know of any other Clojure lib dealing with this (to this extend) so far. Having data sets transformed/mapped into abstract geometric models, it's then easy to create visualizations in all sorts of formats, but one can't do this if only working with an output-specific graphics lib (e.g. SVG centric). Also, one of the next releases under the thi.ng umbrella will be a RDF and SPARQL-like toolkit, which will provide a more direct (and missing) link to use this geom package for data viz purposes. I've already used both (+luxor) in combo to create some 3d visualizations of open data sets about London boroughs for the ODI Summit last October. For that project we had approx. 1600 CSV files of published borough spending data, ambulance crime stats and GPS shapes from the UK Statistics office. These were all combined into an RDF dataset, from which I created a 60sec animated 3d heatmap of the boroughs, rendered in full HD with Luxrender on AWS with 350 CPUs. At my workshop at Resonate in Belgrade (in 2 weeks time) we will explore this kind of approach further. Next time you're at MastotonC, you should ask around if someone @ ODI can show you the video. An image of it is here[1]. @Kuba - I'm afraid toxiclibs is pretty much a closed chapter by now and it's been over 2 years since I worked on my last Java project. I've been meaning to cut one more release (0021), which I've been sitting on and using for various workshops, but getting this out is always a (too) daunting process (also thanks to Processing 2.0) and honestly is very low priority over the next 4 months... The source is up on bitbucket[2] though, but I can't release this until I've checked updated all 100+ examples and added docs for the last additions. @Lee - Thank you too! The GP part of my DevArt project[3] is (as I said in the video) more metaphorical. The way I see it is that visitors in the gallery will fulfill the fitness function and vote on designs created by the people using the online design tool. Every day the visitors will choose one of the created objects to be 3d printed in the gallery and hence indirectly (and over time) inform design decisions made by the designers (who want their creation to be fabricated). These designers are, in a way, the population of the GP and continuously autonomously evolve the genome of the generative design process encoded by the tool. The design options will be fairly limited and only involve subdivision, extrusion replication steps. These steps are encoded in an AST for each object, for which I still have to create an easy-to-use visual programming env, in the browser. To allow for cross-breeding re-use, people will be able to cut paste short DNA sequences from other existing objects. Each such re-use will be logged and forms a graph of co-authorships.

Re: [ANN] 1st public release of thi.ng geometry toolkit (CLJ CLJS)
Two other things: 1) The link to the snap of the ODI video I mentioned earlier should be: http://twitter.com/reasonsto/status/439416380761591809 2) @Kuba - In terms of working on a large codebase in Clojure: As a long term Eclipse user for my previous Java work, I still occasionally miss its amazing refactoring tools, but Emacs with a bunch of add-ons (helm, org-mode, projectile especially iedit-mode(!!!)) brings me 90+% there too (by now). I also can't emphasize enough, how much adopting org-mode a literate programming format for my recent projects has increased my productivity and generally reduced the cognitive load of navigating organizing a large project. So in general (and taking into account all the other positive things Clojure enables me to do), I'm very happy with my current process so far... On the more problematic side: One of the most hairy obstructing things though, has been Clojure's insistence of non-circular dependencies between namespaces and I've yet to come up with a solution to truly make this work as elegant as I think it could/should be. I do understand the reasons reasoning behind that limitation, but the truth is, there're a number of use cases where there simply is no clean way to avoid a circular nature and in total I've probably lost a few weeks just trying to find a workaround for this project alone. In the specific case of this project and to avoid having to pack everything into a huge monolithic namespace, I ended up defining all non-core `defrecords` in a dedicated ns (thi.ng.geom.types) which is then `(:required)` by the different entity namespaces and their implementations provided via `extend-type` only (instead of being able to use the faster runtime path and include protocol impls as part of `defrecord`). The other issue with this approach is that a user of the library needs to include namespaces which he might not even directly use, for example: If I wanted to compute the area of the bounding rect of a triangle, I should just be able to write: (require '[thi.ng.geom.core :as g] '[thi.ng.geom.triangle :as t]) (- (t/equilateral2 [0 0] [100 0]) (g/bounds) (g/area)) However, this will fail with: IllegalArgumentException No implementation of method: :area of protocol:#'thi.ng.geom.core/PArea found for class: thi.ng.geom.types.Rect clojure.core/-cache-protocol-fn The reason for this is that the triangle ns can't refer to the rect ns (which provides the implementation of `area` for rects) and vice versa. Hence the user will have to also manually require the rect ns (even though it's not directly used) in order to make this work: (require '[thi.ng.geom.core :as g] '[thi.ng.geom.triangle :as t] '[thi.ng.geom.rect]) (- (t/equilateral2 [0 0] [100 0]) (g/bounds) (g/area)) ;; = 8660.254037844386 There're a many, many such inter-dependencies in this project and IMHO all of them are valid and not necessarily bad design: E.g. A circle or rect could be sampled/interpreted as polygon, but I also want to compute the bounding circle/rect of a polygon. Similarly, triangles are polygons too, but polygons can be tessellated into triangles. All of these have edges/lines, but lines have bounding rects/circles too etc. Since all of these types and operations are working via protocols, I could see no better way than what I've currently done. If anyone has some clever idea to improve on this (and is CLJS compatible), I'm all ear!

Re: [ANN] 1st public release of thi.ng geometry toolkit (CLJ CLJS)
Hey, Karsten great stuff and congrats! I haven't been following toxic closely for quite some time, sadly but does that mean it's been discontinued completely and you are working in clojure full time? :) What's your impression on working with big code base as above library in clojure vs java? Does clojure scales well? I'm particularly interested in functional vs OO approach and If any performance critical stuff was done in java? If you could share some thoughts would be great.

Karsten, This is amazing. Watching you work with your geom library in this fantastic video has really inspired me :- http://www.youtube.com/watch?v=tKIVJ2TaS2kfeature=youtu.bet=20m9s I've been looking for some geom library to build animated data visualizations, so I'm looking forward to exploring this more. Thanks for making this available to everyone - it's obviously been a huge amount of work.
