Three.js: उदाहरण: webgl_shaders_ocean के साथ समस्या

मैंने अभी उदाहरण dev DeFan पर FF 52.4 और FF 58.0 के साथ चलाया है, ऐसा नहीं हुआ।

ज्यामिति पीआर में बहुत ज्यादा नहीं बदली, टुकड़े टुकड़े में सिर्फ getShadowMask() कॉल करने के लिए आवश्यक हिस्सा शामिल हैं।

क्या त्रुटि संदेश लॉग करता है जो 0:102(109) ?

दुर्भाग्य से नहीं। लाइन 27 के बाद कटे हुए टुकड़े टुकड़े हो गए।

अगर मैं टुकड़े shader में टुकड़े shader ( THREE.Water ) को हटा देता हूं और getShadowMask() कॉल करता हूं, तो त्रुटि गायब हो जाती है।

दुर्भाग्य से नहीं। लॉग टुकड़ा टुकड़ा 27 लाइन The के बाद बंद हो जाता है

सवाल के लिए माफी, लेकिन वहाँ एक _ [...] _ shader लॉग के अंत में जहां यह कट जाता है?

@moraxy उस सलाह के लिए धन्यवाद! जब मैं _ [...] _ पर क्लिक करता हूं, तो मैं पूरा कार्यक्रम देख सकता हूं।
यहाँ पूरा टुकड़ा shader है:

एकमात्र नमूना जो एक गैर-स्थिर अभिव्यक्ति के साथ अनुक्रमित हो जाता है, वह लाइन 668 में directionalShadowMap लगता है? पता नहीं क्यों यह 0:102(109) को संदर्भित करता है।

668: shadow *= bool( directionalLight.shadow ) ? getShadow( directionalShadowMap[ i ], directionalLight.shadowMapSize, directionalLight.shadowBias, directionalLight.shadowRadius, vDirectionalShadowCoord[ i ] ) : 1.0;

अन्य छाया मानचित्र उदाहरण काम करते हैं। यह THREE.Water विशिष्ट टुकड़ा shader के साथ कुछ करना है ...

एक ही निष्कर्ष। यह पंक्ति 2 पर एक एन एक्सटेंशन के लिए एक चेतावनी भी रिपोर्ट करता है जो दिखाई नहीं देता है, इसलिए यह एक अलग कोड का उल्लेख हो सकता है कि लॉग क्या है?

इसी तरह से https://github.com/mrdoob/three.js/issues/6115 में भी मुद्दा

जैसा कि @moraxy ने कहा है और इस मुद्दे का सुझाव है, यह छाया से जोड़ा जा सकता है क्योंकि गैर-कॉन्स्टेबल अभिव्यक्ति के साथ एकमात्र नमूना सरणी है: क्या होगा यदि आप उदाहरण में water.receiveShadow = true निकालते हैं?

मुझे लगता है कि इस बीच मैं किसी भी विचार है कि shader खुदाई कर रहा हूँ ...

क्या होगा अगर आप पानी हटा दें। उदाहरण में सच = श्रेयशो = सच?

वह समस्या का समाधान करता है।

@ मुगें87 स्पेल एडिटर उदाहरण में छाया आपके

हां, webgl_geometry_spline_editor काम करता है।

क्यों इन दोनों उदाहरणों में समान shadowmask_pars_fragment चंक आउटपुट दो भिन्न getShadowMask कार्य करता है? पानी छायादार में यह गैर-स्थिरांक के साथ लूप के लिए है, जो नमूना संपादक सरणियों के शैडोमीटर कार्यक्रम में, यह नहीं करता है:

लूप अनियंत्रित? एक लूप या निर्देश या कुछ होना चाहिए ताकि वह प्रति लूप को सक्षम / अक्षम कर सके

क्या रेंडरर अंतर्निहित सामग्री (इसको शैडो और लैम्बर्ट सामग्रियों में उपयोग किया जाता है) के साथ आंतरिक रूप से अनियंत्रित रूप से लूप को प्राप्त करता है और ShaderMaterial के साथ नहीं?

यह सही है, https://github.com/mrdoob/three.js/blob/dev/src/renderers/webgl/WebGLProgram.js#L509 -L514 देखें

हम इससे कैसे निपटेंगे?

अच्छा प्रश्न। मुझे याद है कि एक उपयोगकर्ता का एक फीचर अनुरोध था जिसने एक उदाहरण के लिए पूछा था कि पता चलता है, कस्टम shader सामग्री पर प्रकाश + छाया कैसे लागू करें (दुर्भाग्य से, मैं अभी समस्या नहीं ढूंढ सकता हूं)। लेकिन हम इसे लागू करते समय एक ही त्रुटि में भाग लेंगे।

मुझे यकीन नहीं है कि इस समस्या को कैसे हल किया जाए। चलिए इंतजार करते हैं कि @mrdoob और @WestLangley किस मुद्दे का मूल्यांकन करते हैं।

https://github.com/mrdoob/three.js/issues/12114

एक उपयोगकर्ता के रूप में यह एक बड़ा सवाल है, क्योंकि GPGPU मामलों में हम ShaderMaterial के साथ भारी for लूप का उपयोग कर सकते हैं, जबकि दूसरी ओर हमें इस तरह के चंक का उपयोग करने में सक्षम होना चाहिए यदि हम विशेष सामग्री डिज़ाइन करना चाहते हैं ShaderMaterial के साथ।

इस स्थिति को बनाए रखने और हटाने दोनों ही मुद्दों का कारण बनते हैं। @moraxy ने एक ध्वज का उपयोग करने का

यह भी मुझे लगता है कि सभी SO प्रश्न और मुद्दों के साथ चल रहा है, मैं shaders को अनुकूलित करने की सामान्य समस्या है ... मैं onBeforeCompile प्यार करता हूँ, लेकिन एक ShadowMaterial पर इसका उपयोग करके पानी के shader बनाना ... यह मुश्किल लग सकता है ... और अन्य संबंधित प्रश्नों को हल नहीं करेगा।

मैं आपको इसे हल करने देता हूं: निर्दोष:

मुझे लगता है कि हम एक जोड़ने की कोशिश कर सकते unrollLoops करने के लिए संपत्ति ShaderMaterial ?

if ( material.isShaderMaterial === undefined || material.unrollLoops === true ) {

बढ़िया है!

@Astrak

इस shader इंस्पेक्टर क्या आप के स्क्रीनशॉट पोस्ट किया है?

@ पेलहेड वह इंस्पेक्टर है , जो क्रोम और फायरफॉक्स के एक्सटेंशन के रूप में उपलब्ध है।
