+ ضوء ينبعث في اتجاه محدد. سيتصرف هذا الضوء كما لو كان بعيدًا لانهائيًا وأن الأشعة المنبعثة منه كلها + متوازية. الاستخدام الشائع لهذا هو محاكاة ضوء النهار ؛ الشمس + بعيد بما يكفي بحيث يمكن اعتبار موقعه لانهائيًا ، و + جميع أشعة الضوء القادمة منه متوازية.

+ + يمكن لهذا الضوء إلقاء الظلال - انظر صفحة [page:DirectionalLightShadow] + للتفاصيل. +

+ +

ملاحظة حول الموقف والهدف والدوران

+

+ نقطة شائعة من الالتباس بالنسبة للأضواء الاتجاهية هي أن تحديد + لا يؤثر التدوير. هذا لأن DirectionalLight في three.js هو + ما يعادل ما يسمى بـ "Target Direct Light" في غيره + التطبيقات.

+ + هذا يعني أن اتجاهه يتم حسابه كمؤشر من ضوء + [page:Object3D.position position] إلى [page:.target target] الموقف + (على عكس "Free Direct Light" التي لديها فقط دوران + مكون).

+ + السبب في ذلك هو السماح للضوء بإلقاء الظلال - ال + [page:.shadow shadow] تحتاج الكاميرا إلى موقف لحساب الظلال + من.

+ + انظر خاصية [page:.target target] أدناه للحصول على تفاصيل حول تحديث + الهدف. +

+ +

مثال للكود

+ + + // ضوء اتجاهي أبيض بشدة نصفية يشرق من الأعلى. + const directionalLight = new THREE.DirectionalLight( 0xffffff, 0.5 ); + scene.add( directionalLight ); + + +

+ يتيح التحديثات التلقائية لظل الضوء. الافتراضي هو `true`. إذا كنت + لا تتطلب إضاءة / ظلال ديناميكية ، يمكنك تعيين هذا على `false`. +

+ +

[property:Camera camera]

+

+ رؤية الضوء للعالم. يتم استخدام هذا لإنشاء خريطة عمق لـ + المشهد ؛ الأشياء خلف الأشياء الأخرى من منظور الضوء ستكون + في الظل. +

+ +

[property:Float bias]

+

+ انحياز خريطة الظل ، كم يجب إضافة أو طرح من العمق المعاد تدويره + عند تحديد ما إذا كانت سطحًا في الظل.
+ الافتراضي هو 0. قد تساعد التعديلات الصغيرة جدًا هنا (بترتيب 0.0001) + تقليل التحف في الظلال +

+ +

[property:Integer blurSamples]

+

عدد العينات المستخدمة عند طمس خريطة ظل VSM.

+ +

[property:WebGLRenderTarget map]

+

+ خريطة العمق التي تم إنشاؤها باستخدام الكاميرا الداخلية ؛ موقع خارج + عمق بكسل في الظل. يتم حسابه داخليًا أثناء التقديم. +

+ +

[property:WebGLRenderTarget mapPass]

+

+ خريطة التوزيع التي تم إنشاؤها باستخدام الكاميرا الداخلية ؛ يتم حساب احتجاب + بناءً على توزيع الأعماق. يتم حسابه داخليًا أثناء + التقديم. +

+ +

[property:Vector2 mapSize]

+

+ [Page:Vector2] يحدد عرض وارتفاع خريطة الظل.

+ + تعطي قيم أعلى جودة أفضل للظلال بتكلفة وقت الحساب. + يجب أن تكون قيم قوى 2 ، حتى + [page:WebGLRenderer.capabilities].maxTextureSize لجهاز معين, + على الرغم من أنه لا يجب أن يكون نفسه (ولذلك ، على سبيل المثال ، + (512، 1024) صالح). الافتراضي هو * (512، 512) *. +

+ نموذج لمساحة الكاميرا الظلية ، لحساب الموقع والعمق في خريطة الظل. + تخزين في [page:Matrix4 Matrix4]. يتم حساب هذا داخليًا أثناء + التقديم. +

+ +

[property:Boolean needsUpdate]

+

+ عند تعيينه على `true` ، سيتم تحديث خرائط الظل في الاتصال التالي `render`. + الافتراضي هو `false`. إذا قمت بتعيين [page:.autoUpdate] على `false` ، فأنت + سوف تحتاج إلى تعيين هذه الخاصية على `true` ثم إجراء مكالمة تقديم لـ + تحديث ظل الضوء. +

+ +

[property:Float normalBias]

+

+ يحدد كمية الموضع المستخدم للاستعلام عن خريطة الظل معوضًا عن + الكائن الطبيعي. الافتراضي هو 0. يمكن استخدام زيادة هذه القيمة لـ + تقليل حب الشباب في الظلال خاصة في المشاهد الكبيرة التي يضيء فيها الضوء + الهندسة بزاوية ضحلة. التكلفة هي أن الظلال قد تبدو + مشوه. +

+ +

[property:Float radius]

+ + بشكل عام يجب أن يكون ذلك كافيًا، ولكن هناك أوقات يمكن أن تكون فيها + مفيدًا لديك محملات منفصلة - على سبيل المثال إذا كنت ترغب في عرض + شرائط تحميل منفصلة للأشياء والقوام. +

+ +

مثال للكود

+ +

+ يوضح هذا المثال كيفية استخدام LoadingManager لتتبع التقدم + [page:OBJLoader]. +

+ + + const manager = new THREE.LoadingManager(); + manager.onStart = function ( url, itemsLoaded, itemsTotal ) { + console.log( 'Started loading file: ' + url + '.\nLoaded ' + itemsLoaded + ' of ' + itemsTotal + ' files.' ); + }; + + manager.onLoad = function ( ) { + console.log( 'Loading complete!'); + }; + + manager.onProgress = function ( url, itemsLoaded, itemsTotal ) { + console.log( 'Loading file: ' + url + '.\nLoaded ' + itemsLoaded + ' of ' + itemsTotal + ' files.' ); + }; + + manager.onError = function ( url ) { + console.log( 'There was an error loading ' + url ); + }; + + const loader = new THREE.OBJLoader( manager ); + loader.load( 'file.obj', function ( object ) { + // + } ); + + +

+ بالإضافة إلى مراقبة التقدم، يمكن استخدام LoadingManager ل + تجاوز عناوين URL للموارد أثناء التحميل. قد يكون ذلك مفيدًا للأصول + القادمة من أحداث السحب والإفلات، WebSockets، WebRTC، أو غيرها من واجهات برمجة التطبيقات. A + مثال يظهر كيفية تحميل نموذج في الذاكرة باستخدام عناوين URL لـ Blob أدناه. +

+ + + // Blob or File objects created when dragging files into the webpage. + const blobs = {'fish.gltf': blob1, 'diffuse.png': blob2, 'normal.png': blob3}; + + const manager = new THREE.LoadingManager(); + + // Initialize loading manager with URL callback. + const objectURLs = []; + manager.setURLModifier( ( url ) => { + + url = URL.createObjectURL( blobs[ url ] ); + objectURLs.push( url ); + return url; + + } ); + + // Load as usual, then revoke the blob URLs. + const loader = new THREE.GLTFLoader( manager ); + loader.load( 'fish.gltf', (gltf) => { + + scene.add( gltf.scene ); + objectURLs.forEach( ( url ) => URL.revokeObjectURL( url ) ); + + }); + + +

    +
  • + طلاء شفاف: بعض المواد - مثل طلاءات السيارات والألياف الكربونية و + الأسطح الرطبة - تتطلب طبقة شفافة عاكسة فوق طبقة أخرى + قد تكون غير منتظمة أو خشنة. يقرب الطلاء الشفاف هذا التأثير، + دون الحاجة إلى سطح شفاف منفصل. +
    • +
  • + الشفافية المستندة إلى الفيزياء: إحدى قيود + [page:Material.opacity .opacity] هو أن المواد شديدة الشفافية + أقل انعكاسية. يوفر [page:.transmission] المستند إلى الفيزياء + خيارًا أكثر واقعية للأسطح الشفافة الرقيقة مثل الزجاج. +

شيدرات الرأس وشيدرات الجزء (Vertex shaders and fragment shaders)

+ +
+

يمكنك تحديد نوعين مختلفين من الشيدرات لكل مادة:

+
    +
  • + يعمل شيدر الرأس أولاً؛ يتلقى `attributes`، يحسب / + يعدل موضع كل رأس فردي، ويمرر + بيانات إضافية (`varying`s) إلى شيدر الجزء. +
    • +
  • + يعمل شيدر الجزء (أو البكسل) ثانيًا؛ يضبط لون + كل "جزء" فردي (بكسل) يتم عرضه على الشاشة. +
    • +
+

+ هناك ثلاثة أنواع من المتغيرات في الشيدرات: الموحدات، والسمات، و + varyings: +

+
    +
  • + `Uniforms` هي متغيرات لها نفس القيمة لجميع الرؤوس - + الإضاءة، والضباب، وخرائط الظل هي أمثلة على البيانات التي ستكون + مخزنة في الموحدات. يمكن الوصول إلى الموحدات من قبل كل من شيدر الرأس + وشيدر الجزء. +
    • +
  • + `Attributes` هي متغيرات مرتبطة بكل رأس - على سبيل المثال، + موضع الرأس، والوجه الطبيعي، ولون الرأس هي جميعها أمثلة على + البيانات التي ستكون مخزنة في السمات. يمكن `فقط` الوصول إلى السمات + داخل شيدر الرأس. +
    • +
  • + `Varyings` هي متغيرات تُمَرَّر من شيدر الرأس إلى + شيدر الجزء. لكل جزء، ستتم تقديم قيمة كل varying بشكل سلس من قِبَال رؤوس مجاورة. +
    • +
+

+ يجب ملاحظة أن `within` الشيدر نفسه، تعمل الموحدات والسمات مثل + المستمرات؛ يمكنك فقط تعديل قِبَالها بتمرير قِبَال مختلفة + إلى المخازن من كود JavaScript الخاص بك. +

+
+ +

السمات والموحدات المدمجة (Built-in attributes and uniforms)

+ +
+

+ يوفر [page:WebGLRenderer] العديد من السمات والموحدات إلى + الشيدرات افتراضيًا؛ يتم إلحاق تعريفات هذه المتغيرات بكود + `fragmentShader` و `vertexShader` الخاص بك من قبل [page:WebGLProgram] عندما + يتم تجميع الشيدر؛ ليس عليك إعلانها بنفسك. انظر + [page:WebGLProgram] للحصول على تفاصيل هذه المتغيرات. +

+

+ بعض هذه الموحدات أو السمات (على سبيل المثال تلك المتعلقة بالإضاءة، + الضباب، إلخ) تتطلب تعيين خصائص على المادة لكي + [page:WebGLRenderer] لنسخ القيم المناسبة إلى GPU - تأكد من تعيين هذه العلامات إذا كنت ترغب في استخدام هذه الميزات في شيدرك الخاص. +

+

+ إذا كنت لا ترغب في أن يضيف [page:WebGLProgram] أي شيء إلى كود شيدرك + ، يمكنك استخدام [page:RawShaderMaterial] بدلاً من هذه الفئة. +

+
+ +

السمات والموحدات المخصصة (Custom attributes and uniforms)

+ +
+

+ يجب إعلان كل من السمات والموحدات المخصصة في كود GLSL shader + (داخل `vertexShader` و / أو `fragmentShader`). يجب تعريف الموحدات المخصصة + في `both` خاصية `uniforms` لـ + `ShaderMaterial`، في حين يجب تعريف أي سمات مخصصة عبر + [page:BufferAttribute] instances. يجب ملاحظة أن `varying`s يجب فقط أن + يتم إعلانها داخل كود الشيدر (وليس داخل المادة). +

+

+ لإعلان سمة مخصصة، يرجى الإشارة إلى + [page:BufferGeometry] للحصول على نظرة عامة، و + [page:BufferAttribute] للحصول على نظرة مفصلة على API `BufferAttribute`. +

+

+ عند إنشاء سماتك، يجب أن يكون كل مجموعة مُطَبَّقَة التي تقوم بإنشائها لحفظ بيانات سمتك مضروبًا في حجم نوع بياناتك. على سبيل المثال، إذا كانت سمتك من نوع [page:Vector3 THREE.Vector3] ، وكان لديك 3000 رأس في [page:BufferGeometry] ، فيجب إنشاء قيمة مجموعتك المُطَبَّقَة بطول 3000 * 3 ، أو 9000 (قيمة واحدة + لكل مُكَوِّن). يظهر جدول حجم كل نوع من أنواع البيانات أدناه للإشارة: +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+ Attribute sizes +
GLSL typeJavaScript typeSize
float[page:Number]1
vec2[page:Vector2 THREE.Vector2]2
vec3[page:Vector3 THREE.Vector3]3
vec3[page:Color THREE.Color]3
vec4[page:Vector4 THREE.Vector4]4
+ +

+ يجب ملاحظة أن مخازن السمات `ليست` تتحدث تلقائيًا عندما تتغير قيمها. لتحديث السمات المخصصة، قم بتعيين علامة `needsUpdate` + إلى true على [page:BufferAttribute] للهندسة (انظر + [page:BufferGeometry] لمزيد من التفاصيل). +

+ +

+ لإعلان [page:Uniform] مخصص، استخدم خاصية `uniforms`: + +uniforms: { + time: { value: 1.0 }, + resolution: { value: new THREE.Vector2() } +} + +

+ +

+ يوصى بتحديث قيم [page:Uniform] المخصصة اعتمادًا على + [page:Object3D object] و [page:Camera camera] في + [page:Object3D.onBeforeRender] لأن [page:Material] يمكن أن يتم مشاركته + بين [page:Mesh meshes]، يتم تحديث [page:Matrix4 matrixWorld] لـ [page:Scene] و + [page:Camera] في [page:WebGLRenderer.render]، وبعض + المؤثرات تعرض [page:Scene scene] باستخدام خاصة بهم [page:Camera cameras]. +

+ + يسمح هذا لـ[page:Vector3] يمثل نقطة في الفضاء ثلاثي الأبعاد بالخضوع + التحولات مثل الترجمة والدوران والقص والتحجيم والانعكاس و + الإسقاط المتعامد أو المنظور وهكذا ، عن طريق ضربه بـ + المصفوفة. يُعرف هذا باسم `تطبيق` المصفوفة على المتجه.

+ + كل [page:Object3D] لديه ثلاث Matrix4s مرتبطة: +

+
    +
  • + [page:Object3D.matrix]: يخزن هذا التحول المحلي للكائن. + هذا هو تحول الكائن نسبةً إلى والده. +
    • +
  • + [page:Object3D.matrixWorld]: التحول العالمي أو العالمي لـ + الكائن. إذا لم يكن للكائن والد ، فإن هذا مطابق للتحول المحلي + المخزن في [page:Object3D.matrix matrix]. +
    • +
  • + [page:Object3D.modelViewMatrix]: يمثل هذا تحول الكائن + نسبةً إلى نظام إحداثيات الكاميرا. مصفوفة modelViewMatrix للكائن هي + matrixWorld للكائن مضروبًا بـ + matrixWorldInverse للكاميرا. +
    • +
+ + [page:Camera Cameras] لديها ثلاث Matrix4s إضافية: +
    +
  • + [page:Camera.matrixWorldInverse]: مصفوفة العرض - عكس + Camera's [page:Object3D.matrixWorld matrixWorld]. +
    • +
  • + [page:Camera.projectionMatrix]: يمثل المعلومات حول كيفية + إسقاط المشهد على مسافة قص. +
    • +
  • + [page:Camera.projectionMatrixInverse]: عكس projectionMatrix. +
    • +
+ + ملاحظة: [page:Object3D.normalMatrix] ليست Matrix4 ، ولكنها [page:Matrix3]. + +

ملاحظة حول ترتيب الصف الرئيسي والعمود الرئيسي

+

+ يأخذ الباني وطريقة [page:set]() المعاملات في + [link:https://en.wikipedia.org/wiki/Row-_and_column-major_order#Column-major_order row-major] + ترتيب ، في حين يتم تخزينها داخليًا في مصفوفة [page:.elements elements] بترتيب العمود الرئيسي.

+ + هذا يعني أن الاتصال + + const m = new THREE.Matrix4(); + m.set( 11، 12، 13، 14، + 21، 22، 23، 24, + 31، 32، 33، 34، + 41، 42، 43، 44 ); + + ستؤدي إلى مصفوفة [page:.elements elements] التي تحتوي على: + + m.elements = [ 11, 21, 31, 41, + 12, 22, 32, 42, + 13, 23, 33, 43, + 14, 24, 34, 44 ]; + + وداخليًا يتم إجراء جميع الحسابات باستخدام ترتيب العمود الرئيسي. + ومع ذلك ، نظرًا لأن الترتيب الفعلي لا يحدث فرقًا رياضيًا و + معظم الناس معتادون على التفكير في المصفوفات بترتيب الصف الرئيسي ، + توثق three.js المصفوفات بترتيب الصف الرئيسي. فقط تذكر أنه إذا كنت + قراءة شفرة المصدر ، ستضطر إلى أخذ + [link:https://en.wikipedia.org/wiki/Transpose transpose] من أية مصفوفات + الموضح هنا لجعل المحاسبات منطقية. +

استخراج الموضع والدوران والمقياس

+

+ هناك العديد من الخيارات المتاحة لاستخراج الموضع والدوران و + المقياس من Matrix4. +

+
    +
  • + [page:Vector3.setFromMatrixPosition]: يمكن استخدامه لاستخراج + مكون الترجمة. +
    • +
  • + [page:Vector3.setFromMatrixScale]: يمكن استخدامه لاستخراج المقياس + مكون. +
    • +
  • + [page:Quaternion.setFromRotationMatrix] ، + [page:Euler.setFromRotationMatrix] أو [page:.extractRotation extractRotation] + يمكن استخدامه لاستخراج مكون الدوران من مصفوفة نقية (غير متساوية القياس). +
