ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM +CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT. + +1. DEFINITIONS + +"Contribution" means: + +a) in the case of the initial Contributor, the initial code and +documentation distributed under this Agreement, and + +b) in the case of each subsequent Contributor: + +i) changes to the Program, and + +ii) additions to the Program; + +where such changes and/or additions to the Program originate from and are +distributed by that particular Contributor. A Contribution 'originates' from +a Contributor if it was added to the Program by such Contributor itself or +anyone acting on such Contributor's behalf. Contributions do not include +additions to the Program which: (i) are separate modules of software +distributed in conjunction with the Program under their own license +agreement, and (ii) are not derivative works of the Program. + +"Contributor" means any person or entity that distributes the Program. + +"Licensed Patents" mean patent claims licensable by a Contributor which are +necessarily infringed by the use or sale of its Contribution alone or when +combined with the Program. + +"Program" means the Contributions distributed in accordance with this +Agreement. + +"Recipient" means anyone who receives the Program under this Agreement, +including all Contributors. + +2. GRANT OF RIGHTS + +a) Subject to the terms of this Agreement, each Contributor hereby grants +Recipient a non-exclusive, worldwide, royalty-free copyright license to +reproduce, prepare derivative works of, publicly display, publicly perform, +distribute and sublicense the Contribution of such Contributor, if any, and +such derivative works, in source code and object code form. + +b) Subject to the terms of this Agreement, each Contributor hereby grants +Recipient a non-exclusive, worldwide, royalty-free patent license under +Licensed Patents to make, use, sell, offer to sell, import and otherwise +transfer the Contribution of such Contributor, if any, in source code and +object code form. This patent license shall apply to the combination of the +Contribution and the Program if, at the time the Contribution is added by the +Contributor, such addition of the Contribution causes such combination to be +covered by the Licensed Patents. The patent license shall not apply to any +other combinations which include the Contribution. No hardware per se is +licensed hereunder. + +c) Recipient understands that although each Contributor grants the licenses +to its Contributions set forth herein, no assurances are provided by any +Contributor that the Program does not infringe the patent or other +intellectual property rights of any other entity. Each Contributor disclaims +any liability to Recipient for claims brought by any other entity based on +infringement of intellectual property rights or otherwise. As a condition to +exercising the rights and licenses granted hereunder, each Recipient hereby +assumes sole responsibility to secure any other intellectual property rights +needed, if any. For example, if a third party patent license is required to +allow Recipient to distribute the Program, it is Recipient's responsibility +to acquire that license before distributing the Program. + +d) Each Contributor represents that to its knowledge it has sufficient +copyright rights in its Contribution, if any, to grant the copyright license +set forth in this Agreement. + +3. REQUIREMENTS + +A Contributor may choose to distribute the Program in object code form under +its own license agreement, provided that: + +a) it complies with the terms and conditions of this Agreement; and + +b) its license agreement: + +i) effectively disclaims on behalf of all Contributors all warranties and +conditions, express and implied, including warranties or conditions of title +and non-infringement, and implied warranties or conditions of merchantability +and fitness for a particular purpose; + +ii) effectively excludes on behalf of all Contributors all liability for +damages, including direct, indirect, special, incidental and consequential +damages, such as lost profits; + +iii) states that any provisions which differ from this Agreement are offered +by that Contributor alone and not by any other party; and + +iv) states that source code for the Program is available from such +Contributor, and informs licensees how to obtain it in a reasonable manner on +or through a medium customarily used for software exchange. + +When the Program is made available in source code form: + +a) it must be made available under this Agreement; and + +b) a copy of this Agreement must be included with each copy of the Program. + +Contributors may not remove or alter any copyright notices contained within +the Program. + +Each Contributor must identify itself as the originator of its Contribution, +if any, in a manner that reasonably allows subsequent Recipients to identify +the originator of the Contribution. + +4. COMMERCIAL DISTRIBUTION + +Commercial distributors of software may accept certain responsibilities with +respect to end users, business partners and the like. While this license is +intended to facilitate the commercial use of the Program, the Contributor who +includes the Program in a commercial product offering should do so in a +manner which does not create potential liability for other Contributors. +Therefore, if a Contributor includes the Program in a commercial product +offering, such Contributor ("Commercial Contributor") hereby agrees to defend +and indemnify every other Contributor ("Indemnified Contributor") against any +losses, damages and costs (collectively "Losses") arising from claims, +lawsuits and other legal actions brought by a third party against the +Indemnified Contributor to the extent caused by the acts or omissions of such +Commercial Contributor in connection with its distribution of the Program in +a commercial product offering. The obligations in this section do not apply +to any claims or Losses relating to any actual or alleged intellectual +property infringement. In order to qualify, an Indemnified Contributor must: +a) promptly notify the Commercial Contributor in writing of such claim, and +b) allow the Commercial Contributor tocontrol, and cooperate with the +Commercial Contributor in, the defense and any related settlement +negotiations. The Indemnified Contributor may participate in any such claim +at its own expense. + +For example, a Contributor might include the Program in a commercial product +offering, Product X. That Contributor is then a Commercial Contributor. If +that Commercial Contributor then makes performance claims, or offers +warranties related to Product X, those performance claims and warranties are +such Commercial Contributor's responsibility alone. Under this section, the +Commercial Contributor would have to defend claims against the other +Contributors related to those performance claims and warranties, and if a +court requires any other Contributor to pay any damages as a result, the +Commercial Contributor must pay those damages. + +5. NO WARRANTY + +EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON +AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER +EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR +CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A +PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the +appropriateness of using and distributing the Program and assumes all risks +associated with its exercise of rights under this Agreement , including but +not limited to the risks and costs of program errors, compliance with +applicable laws, damage to or loss of data, programs or equipment, and +unavailability or interruption of operations. + +6. DISCLAIMER OF LIABILITY + +EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY +CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, +SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION +LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN +CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) +ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE +EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY +OF SUCH DAMAGES. + +7. GENERAL + +If any provision of this Agreement is invalid or unenforceable under +applicable law, it shall not affect the validity or enforceability of the +remainder of the terms of this Agreement, and without further action by the +parties hereto, such provision shall be reformed to the minimum extent +necessary to make such provision valid and enforceable. + +If Recipient institutes patent litigation against any entity (including a +cross-claim or counterclaim in a lawsuit) alleging that the Program itself +(excluding combinations of the Program with other software or hardware) +infringes such Recipient's patent(s), then such Recipient's rights granted +under Section 2(b) shall terminate as of the date such litigation is filed. + +All Recipient's rights under this Agreement shall terminate if it fails to +comply with any of the material terms or conditions of this Agreement and +does not cure such failure in a reasonable period of time after becoming +aware of such noncompliance. If all Recipient's rights under this Agreement +terminate, Recipient agrees to cease use and distribution of the Program as +soon as reasonably practicable. However, Recipient's obligations under this +Agreement and any licenses granted by Recipient relating to the Program shall +continue and survive. + +Everyone is permitted to copy and distribute copies of this Agreement, but in +order to avoid inconsistency the Agreement is copyrighted and may only be +modified in the following manner. The Agreement Steward reserves the right to +publish new versions (including revisions) of this Agreement from time to +time. No one other than the Agreement Steward has the right to modify this +Agreement. The Eclipse Foundation is the initial Agreement Steward. The +Eclipse Foundation may assign the responsibility to serve as the Agreement +Steward to a suitable separate entity. Each new version of the Agreement will +be given a distinguishing version number. The Program (including +Contributions) may always be distributed subject to the version of the +Agreement under which it was received. In addition, after a new version of +the Agreement is published, Contributor may elect to distribute the Program +(including its Contributions) under the new version. Except as expressly +stated in Sections 2(a) and 2(b) above, Recipient receives no rights or +licenses to the intellectual property of any Contributor under this +Agreement, whether expressly, by implication, estoppel or otherwise. All +rights in the Program not expressly granted under this Agreement are +reserved. + +This Agreement is governed by the laws of the State of Washington and the +intellectual property laws of the United States of America. No party to this +Agreement will bring a legal action under this Agreement more than one year +after the cause of action arose. Each party waives its rights to a jury trial +in any resulting litigation. diff --git a/penrose-tile/README.md b/penrose-tile/README.md new file mode 100644 index 0000000..dbfc981 --- /dev/null +++ b/penrose-tile/README.md @@ -0,0 +1,18 @@ +# penrose-tile + +A Quil sketch designed to ... well, that part is up to you. + +## Usage + +LightTable - open `core.clj` and press `Ctrl+Shift+Enter` to evaluate the file. + +Emacs - run cider, open `core.clj` and press `C-c C-k` to evaluate the file. + +REPL - run `(require 'penrose-tile.core)`. + +## License + +Copyright © 2016 FIXME + +Distributed under the Eclipse Public License either version 1.0 or (at +your option) any later version. diff --git a/penrose-tile/project.clj b/penrose-tile/project.clj new file mode 100644 index 0000000..2d17e93 --- /dev/null +++ b/penrose-tile/project.clj @@ -0,0 +1,7 @@ +(defproject penrose-tile "0.1.0-SNAPSHOT" + :description "FIXME: write description" + :url "http://example.com/FIXME" + :license {:name "Eclipse Public License" + :url "http://www.eclipse.org/legal/epl-v10.html"} + :dependencies [[org.clojure/clojure "1.10.1"] + [quil "3.1.0"]]) diff --git a/penrose-tile/src/penrose_tile/core.clj b/penrose-tile/src/penrose_tile/core.clj new file mode 100644 index 0000000..2f63e08 --- /dev/null +++ b/penrose-tile/src/penrose_tile/core.clj @@ -0,0 +1,73 @@ +(ns penrose-tile.core + (:require [quil.core :as q] + [quil.middleware :as m])) + +(def axiom "F") +(def rule "F+F-F") +(def start-length 190) +(def theta (q/radians 120)) +(def production (atom (str axiom))) +(def draw-length (atom start-length)) +(def generations (atom 0)) +(def steps (atom 0)) + + +(defn update-step + [] + (if (> @steps (count @production)) + (reset! steps (count @production))) + (swap! steps (partial + 5))) + +(defn iter + [] + (swap! draw-length (partial * 0.6)) + (swap! generations inc) + (swap! production #(clojure.string/replace % "F" rule))) + +(defn simulate + [gen] + (while (< @generations gen) + (iter))) + +(defn parse-string + "Draw the entire LSystem by parsing production" + [] + (update-step) + (q/translate (/ (q/width) 2) (/ (q/height) 2)) + (doseq [step (vec @production)] + (cond + (= step \F) ((q/rect 0 0 (- @draw-length) (- @draw-length)) + (q/translate 0 (- @draw-length))) + (= step \+) (q/rotate @theta) + (= step \-) (q/rotate (- @theta)) + (= step \[) (q/push-matrix) + (= step \]) (q/pop-matrix)))) + + +(defn draw-state [] + ; Set circle color. + (q/background 255) + (q/stroke 0) + (q/rect (/ (q/width) 2) (/ (q/height) 2) 50 50) + (parse-string) + ) + +(defn setup [] + (q/frame-rate 30) + (q/color-mode :hsb) + (simulate 6)) + +(q/defsketch penrose-tile + :title "You spin my circle right round" + :size [500 500] + ; setup function called only once, during sketch initialization. + :setup setup + ; update-state is called on each iteration before draw-state. + :update identity + :draw draw-state + :features [:keep-on-top] + ; This sketch uses functional-mode middleware. + ; Check quil wiki for more info about middlewares and particularly + ; fun-mode. + ;:middleware [m/fun-mode]) + )
