3D Web cov qauv ntaub ntawv nrog API-javascript: Esri Advances
Thaum peb pom ArcGIS Smart Campus functionality, nrog rau kev paub tab xws li cov paths ntawm ib tug duab hauv qib peb ntawm Professional Services lub tsev thiab ib qho hauv Q Auditorium, vim yog ob qho tib si ntawm cov neeg ua haujlwm hauv cov dej num thiab cov ntaub ntawv BIM, Kev koom ua ke ntawm Geo-engineering ntws mus rau hauv ib qho kev pom tsis pom zoo yog ze heev.
Thiab txawm hais tias muaj cov haujlwm tseem ceeb uas ploj lawm los tswj tus tswv cov ntaub ntawv kev tswj hwm (MDM) hom txheej txheem rau qhov taw tes ntawm qhov tseeb ntawm lub teeb pom kev muaj tseeb ntawm GIS, cov ncauj lus kom ntxaws muaj tseeb BIM thiab thov kev tshwm sim hauv lub neej tiag tiag uas khiav ntawm lub pointer no. Peb kuj paub tias tag nrho cov haujlwm no tau khiav ntawm cov web browsers, muaj qee tus Nab hab sej rau kev ua tab sis txhua yam saum toj no nrog cov lus ua lub teeb zoo li javascript.
Yuav ua li cas inevitably reminds peb, hais tias geomatics thiab engineers yuav tau mus ib kauj ruam ntxiv mus to taub qauv, thiab programming codes.
Nws tseem yog qhov tseem ceeb kom nco ntsoov cov kev hloov pauv hloov los ntawm cov duab huab cua ib puag ncig mus rau qhov sib me me ntawm browser snippets. Muaj tseeb tiag tus kws tshawb fawb computer uas tau kos duab nrog GIS server, Gis Cav lossis Gis cov khoom lag luam tawm thaum nws pom yuav ua li cas Leaflet ua haujlwm hauv chav kawm MappingGis; Kuv yuav tsis xav tsis thoob yog tias nws tau mus dhia hla lub qhov ntxa rau nws thawj ntawm kev cob qhia.
Nyob twj ywm tom ntej ArcGis Indoors version, tsab xov xwm no nthuav tawm ua ke ntawm Lau ua kev txaus siab - ib tug ntxhais ntxim hlub uas sib koom tes nrog lub vev xaib no - thiab cov ntsiab lus teb views ntawm tus editor ntawm Geofumadas.com, ntawm webinar tsis ntev los no “Ib qho kev taw qhia rau 3D hauv Web nrog ArcGIS API rau Javascript ".
Cov chaw ua yeeb yam ntawm lub vev xaib thaum xub pib pom zoo nrog qhov zoo ntawm qhov kev kawm txog kev siv 3D hauv ArcGIS daim ntaub ntawv, thiab yuav ua li cas nws tsim kho nws tus kheej hauv cov chaw ntawm: Scene viewer, Story Maps, lossis Web App Builder nyob ntawm lub hom phiaj kawm.
Nws yog ib qho tseem ceeb tias cov ntsiab lus tseem ceeb ntsig txog 3D ntsiab lus tau raug txhais los ntawm theem pib, tshwj xeeb tshaj yog vim hais tias dhau qhov ntawm cov ntsuas ntau, nws nrhiav qauv txheej txheem. Tsis tas li ntawd lub ntsej muag uas tseem tseem ceeb nyob rau hauv cov nqe lus ntawm theem pib cov qauv yuav tsum tau khiav cov txheej txheem txuas nrog cov hom ntaub ntawv no uas txawv ntawm 2D, xws li daim npav zoo daim npav, OpenGL txhawb muaj nyob hauv browser w / WebGL.
Yog tsis yog, qhia rau lawv cov phooj ywg XAIV, nyob rau hauv kev zoo kawg ntawm kev tswj cov cuab yeej cuab tam hauv GIS technologies, uas muaj nws cov teeb meem ua ntej OpenGL versions ntawm Nvidia graphics phaib ntawm lub tsev kawm ntawv uas nws tsim tau. Tau nce ceev zuj zus los ntawm kev tawm tsam ntawm Bogota cov tub ntxhais kawm uas ua rau nws nyuaj rau kev ntsuam xyuas txaus ua ntej hnub.
Tsis tas li ntawd, lawv tau nthuav tawm qhov kev tso tawm los txhawb nqa cov cuab yeej ntawm cov khoom siv txawb xws li xov tooj ntawm tes lossis cov ntsiav tshuaj.
Nyob rau hauv qhov kev nthuav qhia ua ob peb yam piv txwv los yog demonstrations, to taub yuav ua li cas lub API rau JavaScript zog thiab yuav ua li cas cov ntaub ntawv yog sib thooj, tsim kom muaj modeling 3D, pib nrog lub load ntawm khaubncaws sab nraud povtseg los yog cov ntaub ntawv los WebScene thiab tom qab ntawd nws modeling / rendering 3D nyob rau hauv Screeneview,
Kev koom ua haujlwm
Tus qauv kos yog hom 4.x thiab yog tsim los ntawm cov khoom siv pom thiab cov khoom siv dav dav, ntxiv rau kev lees txais ntau txheej txheej ntawm cov ntaub ntawv los ntawm cov ntaub ntawv sib txawv. Cov qauv kos duab no ua tau zoo tshaj 3.x vim tias pom 3D pom tsuas yog muaj rau qib no. Cov cuab yeej Webscene thiab SceneView tau siv los tswj 3D cov ntaub ntawv thiab tau ua tiav cov lej API, ntxiv rau seb cov qauv 3D yuav raug yoog raws li cov ntaub ntawv muaj nyob hauv cov ntawv thov yav dhau los li cas.
Nrog cov piv txwv, lawv tau qhia qhov pom kev sib txawv ntawm 2D thiab 3D cov ntaub ntawv thiab yuav ua li cas los ntawm 2D WebScene daim ntawv qhia pom mus rau 3D SceneView, los ntawm javascript codes. Kev ntxias ntawm lub koob yees duab tau yooj yim, ntxiv qee qhov tshwj xeeb cov lus txib txoj kev xav hloov cov kev taw qhia. Kev ntsuam xyuas tau ua raws li cov cwj pwm hauv qab no:
- nqe, uas tso cai rau txoj kev sib hloov ntawm lub koob yees duab ntawm daim duab ntshoo.
- musTo: yog siv los tsim ib qho saib raws li koj xav pom hauv 3D, ntxiv rau koj tuaj yeem tsim cov animations nrog qhov cuab yeej no, xws li tso qee cov degrees nqe lus hais txog kom rov ua dua ib qho animation.
- ToMap: yuav siv qhov chaw saib xyuas thiab muab tso rau hauv 2D daim ntawv qhia
- phij cuam: tso cai rau koj los qhia qhov taw tes ntawm 2D daim ntawv qhia thiab tso nws rau tom 3D saib
- hitTest: yog siv los txiav txim rau tus yam ntxwv hais tias lub ntsiab lus meej muaj nyob rau hauv qhov kev pom
Lawv kuj txhais tau hais tias qhov kev siv ntawm ib daim ntawv qhia 3D muaj tib cov cuab yeej los tsim ib tug 2d, xws li siv basemaps, khaubncaws sab nraud povtseg los yog khaubncaws sab nraud povtseg uas yog kuj txaus siab tias rau 2D (WMS, vectors los yog CSV).
Txawm li cas los xij, nws yuav tsum raug coj mus rau hauv tus account tias 2D txheej tsis muaj cov ntaub ntawv ntawm "Z" (qhov siab), qhov no yog vim li cas rau cov qauv ntaub ntawv nws yog tsim nyog muaj cov txheej txuam nrog 3D li point huab, Meshlayerslos yog nce siab. Nyob rau hauv lub API koj yuav sab laj rau cov 3D khaubncaws sab nraud povtseg xws li nce kev cov ntsiab lus tsis pub dhau lub xub ntiag, nyob rau hauv cov duab (1) Ameslikas cai teb, thiab cov duab (2) raws li nws hloov los ntawm lus nug lossis kev sab laj.
Lawv tau pom ntau qhov piv txwv ntawm qhov cov ntaub ntawv sawv cev, piv txwv li, cov ntaub ntawv dab tsi txhawb los ntawm SceneLayers (cov ntsiab lus), thiab cov khoom 3D (Cov Khoom 3D).
Rau cov nroog loj, cov sawv cev ntawm 3D cov khoom siv yog cov cuab yeej muaj zog, vim nws muaj peev xwm pom, tsis tsuas yog thaj chaw ntawm qhov khoom, tab sis nws qhov ntim, kev sib raug zoo nrog ib puag ncig, ntxiv rau cov yam ntxwv muaj zog ntawm txhua tus tuaj yeem muab ntxiv. cov khoom. Cov duab hauv qab no qhia tau hais tias lawv yuav xaiv xaiv lub tsev li cas hauv New York City, thiab tag nrho nws cov cwj pwm tuaj yeem pom. Zoo li no, ntau cov lus nug tuaj yeem npaj tau raws li cov kev teeb tsa, xws li: qhov twg qee cov kev teeb tsa uas muaj qhov siab siab tshwj xeeb lossis cov lus txhais ntawm cov kev taug zoo tshaj yog nyob
Txhawb nqa ntawm cov khaubncaws sab nraud povtseg IntegratedMeshLayer, uas yog ib ntu ntawm cov ntaub ntawv los ntawm cov sensors zoo li drones. Lawv tsis qhia cov lus qhia los ntawm txhua tus qauv ua cov duab qub, tab sis nws yog ib pawg ntawm cov ntaub ntawv nrog 3D cwj pwm.
Raws li cov ntsiab lus huab, koj tuaj yeem ua si nrog qhov luaj li cas ntawm cov ntsiab lus kom muaj kev pom kev zoo ntawm cov ntaub ntawv, vim txhua txheej ntawm cov ntsiab lus muaj peev xwm muaj billions ntawm cov lus qhia, tab sis lawv tsis sawv cev raws li 3D khoom nws tus kheej.
Lawv tau teev kev siv cov cim qhia hauv 3D cov ntaub ntawv, uas tau nthuav tawm hauv cov duab tiaj / tiaj, thiab ntim ntim symbology txuam nrog cov khoom tsim hauv 3D. Cov no tuaj yeem ua raws hom tshwj xeeb raws li hom khoom. Lawv pom tias kev siv lub npe hu ua Extrudes rau “xim” tus qauv raws li nws lub peev xwm,
Cov hom cob qhia uas yuav siv tau yog: yooj yim, qhov twg tag nrho cov khoom muaj ib lub cim, lub cimValueRenderer qhov twg koj tuaj yeem categorize cov khoom, raws li tus attribute, thiab Qeb Kawm Txuj Ci Tawm qhov twg ntawm txhua yam khoom raug pom zoo nrog rau ib chav kawm: hauv qhov no lawv tau qhia tias lub tsev ntev npaum li cas thiaj li nkag mus rau hauv lub npav khiav pej xeem.
Cov neeg qhia, tau pom zoo nyob rau hauv lub sij hawm luv luv Tsa Webinar, tag nrho cov txiaj ntsim ntawm kev siv ArcGIS API rau Javascript, suav nrog:
- 3D widgets: nrog kev sib tham ua qauv qhia lawv pom qhov kev ncua deb ntawm cov khoom, ob qho tib si thiab kab ntsig.
- Kev tsim kho ntawm kev siv: los ntawm qhov chaw thiab 3D khoom.
- SceneView scene hom: txhais cov ntsiab lus thiab cov ntsiab lus ntawm 3D pom thiab tuaj yeem xa mus rau Portal rau ArcGIS.
Geodesic kev ntsuam xyuas: tsis tsuas yog tsom rau cov qauv ntawm qhov chaw, tab sis kuj tso cai rau ntsuas qhov ncua deb ntawm lub ntiaj teb.- Tsev daim ntaub ntawv, modeling 3D raws li cov kev muaj tiag hais qhov chaw, cov kab los yog npuas hu qhov twg tej nta qhia, xws li cov cim npe uas nyob rau ntawm platforms xws li Google lub ntiaj teb, nyob rau hauv cov ntaub ntawv no 3D
- Declutter: siv rau purify los yog lim ntawv los yog yam ntxwv uas yuav tsum tau pom nyob rau hauv daim ntawv qhia 3D, yog li tsis txhob ib tug ntau ntawm cov ntawv qhia tias tsis pub kom visualization, thiab ua rau suab nrov thaum nrhiav ib yam dab tsi meej.
Tom qab cov demonstrations ntawm txhua tus yam ntxwv incorporated rau hauv ArcGIS API rau Javascript, tsom cov ntawv tshiab tuaj yeem hais hauv 4.10 version tshiab. Qhov twg koj yuav muaj peev xwm:
- Tsim lub Scene txheej
- Daim ntawv widget: uas yuav kis tau cov ntaub ntawv uas tau tsim los dhau los rau 3D khoom
- Muab cov ntaub ntawv ntau los tso rau hauv: tsis tsuas yog sib thooj rau ib lub nroog, tab sis hauv teb chaws (lub teb chaws).
- Taw tes huab lim
Kev koom tes ntawm no webinar rau geoengineering
Hauv ntej, qhov kev kawm yog qhov siv tau heev; nco ntsoov tias lub ncauj ke rau Digital Twins thiab Smart Nroog xav tau qhov ntawd, dhau ntawm kev xav txog kev tswj ntaub ntawv, uas nws cov qauv tau dhau los zoo, kev koom ua ke nrog kev ua haujlwm qauv ua haujlwm yuav raug daws. Kev ua lag luam yog dav, cog lus thiab mus rau hnub tim nws twb muaj ntau cov kev daws teeb meem rau cov neeg siv kawg; txawm hais tias rau cov ntawm peb cov uas siv thev naus laus zis los ua cov cuab yeej tsis tuaj yeem, txoj kev tseem nyuaj. Qhov no cuam tshuam, sib hloov ua lwm qhov ntev xws li lub sijhawm, tus nqi thiab lub neej ntawm cov txheej txheem; tsis nyob rau theem ntawm cov ntaub ntawv thiab thev naus laus zis, uas, raws li peb xav, yog qhov teeb meem pom tseeb, tab sis theej nyob rau hauv kev hloov kho tsis tshua mob rau tus neeg siv lub neej tiag tiag ua ntej sib cuam tshuam hauv cov lag luam sib txuas uas dhau los ntawm cov ntaub ntawv xov xwm. Los ntawm ESRI sab, cov ntaub ntawv tsim kho yog qhov nyuaj me ntsis, vim tias txawm koj tuaj yeem sib sau ua ke BIM cov ntaub ntawv ua rau saum Revit, nws tseem pom zoo li ob lub ntiaj teb cais uas yuav tsum muaj kev hloov pauv nyuaj. Cov haujlwm tshiab yuav muaj tseeb tuaj yeem siv rau BIM qauv, tab sis muaj cov ntaub ntawv ntau tshaj ntawm CAD cov ntaub ntawv uas coj nws mus rau Sab Nraud Qhov Kev Ua Haujlwm Sab Nraud, nrog rau cov chaw polygonized, qhov nce thiab cov txheej txheem ib txwm muaj tseem kim.
Txawm li cas los xij, yog tias Esri tsim nyog tau txais txiaj ntsig, nws yog qhov kev nce qib uas nws ua rau qhov zoo nkauj thiab pom tau yooj yim. Kuv tuaj yeem xav txog qhov kev poob siab ntawm Mr. Jack, nrog nws cov optics ntawm "cia ua kom yooj yim" cov thawj coj kab ntsug ntawm AutoDesk, nyob rau hauv lig tab sis kev sib yuav ua tiav qhov twg "yuav luag ib daim ntawv thov ArcGIS Pro” yuav tsum nrhiav tau nyob rau hauv cov nplooj ntawv raws li ib tug haum nrog ob peb daim uas taw tes rau tib yam tab sis muaj teeb meem kom yooj yim lub ntsiab ntawm cov txiaj ntsig nrhiav los ntawm topography, Industrial Engineering, Civil Engineering thiab Architecture. Thiab nws yog qhov sib txawv ntawm qhov yooj yim ntawm daim duab kos duab uas GIS raug kev txom nyem, tseem yuav tsum tau ua neej nyob los ntawm cov pa CAD, vim tias tus cwj pwm tsis nco qab tias txoj kev npaj tsuas yog nruab nrab, tab sis qhov tseem ceeb yog muab lub tsev rau kev ua haujlwm. .
Zoo coj modeling GIS, khaub-ncaws nyias, rau abstraction ntawm kev muaj tiag yuav pab tau rau CAD / BIM hybrid, uas rau ib tug thaum yuav tau nyob vim hais tias cov me nyuam los tu ntawm BIM nyob rau hauv ntau lub teb chaws mus rau ntev, tshwj xeeb tshaj yog los ntawm cov kev cai ineptitude laus-fashioned ua hauj lwm dhau los ntawm thawj ob tsab ntawv ntawm AECO lub zeem muag.
Cov haiv neeg no yuav muaj kev lom zem nyob rau hauv lub xyoo tom ntej, nyob rau hauv ib txoj kev zoo sib xws los coj mus rau tus nruam nquag qhov sib lawv liag CAD-GIS-BIM-DigitalTwin-SmartCity; raws li kev tshwm sim ntawm kev ua haujlwm ntawm Sab Siemens / Bentley hauv kev nrhiav tau ntawm kev daws teeb meem xws li CityPlanner thiab kev tso tawm ntawm qhib qhov chaw ntawm Javascript.
Txog tam sim no, cia peb muab Esri credit rau qhov kev sib zog ua ke ntawd nrog AutoDesk, dhau ntawm cov ntaub ntawv / thev naus laus zis sib xyaw, hauv cov txheej txheem / ua yeeb yam ua ke. Thaum kawg, nws yog qhov nce rau cov neeg siv khoom, uas tau tawm los lav tias cov kauj ruam yuav kawm kom nkag siab txog cov qauv thiab kev cai; kom pib tsawg kawg ArcGIS Pro cov chav kawm thiab ntu Javascript.
