Kev lig kev cai, pov rau cov pob txha tawg yog ua los ntawm hnyav, tawv, tsis nqus pa. Qhov no tuaj yeem tsim kev tsis xis nyob thiab teeb meem tawv nqaij rau tus neeg mob thaum lub sijhawm kho, zoo li khaus khaus, ua pob liab liab thiab kab mob ntawm daim tawv nqaij. Kev cai 3D luam tawm ua nrog ua pa, ua qauv voronoi yog qhov peev xwm DIY daws tau. Txoj hauv kev no pom tseeb tsis tau pom zoo los ntawm kws kho mob (tam sim no) thiab yuav tsum tsis txhob siv qhov chaw pom koj tus kws kho mob. Txawm li cas los xij, yog tias koj ib txwm hnav lub dab teg sib cais/lwm yam txhawm rau raug mob koj tuaj yeem tsim koj tus kheej li kev cai ntawm qhov no nrog kev pom zoo los ntawm koj tus kws kho mob lossis kws tshaj lij.

Thaum qhov no yog qhov muaj peev xwm daws tau zoo, ua qauv 3D thiab 3D luam tawm ib qho kev pov tseg los yog brace yog siv sijhawm. Tus qauv 3D luam ntawm lub dab teg pov tseg yuav siv sijhawm kwv yees li 3 teev los luam tawm ntawm lub tshuab luam ntawv 3D, qhov chaw uas plaster yuav siv sijhawm li ib nrab teev kom haum rau tus neeg mob thiab nws raug nqi zoo heev. Txoj kev no yog DIY daws rau kev sim nkaus xwb. Kuv twb tau blogged yav dhau los yuav ua li cas los tsim lub dab teg siv Meshmixer, txoj hauv kev no nyuaj dua tab sis muaj txiaj ntsig zoo dua thiab haum zoo dua. Txhawm rau ua ib qho ntawm no, koj yuav xav tau lub tshuab luam ntawv 3D thiab luam Meshmixer thiab Rhino 3D software, nrog Grasshopper, teeb tsa tus qauv algorithmic tau teeb tsa.

Nov yog daim vis dis aus nrog taug kev ntawm Rhino cov kauj ruam:

Kauj ruam 1: 3D Scanning

Ua ntej tshaj, koj yuav tsum tau tshuaj xyuas qhov zoo ntawm thaj chaw uas koj xav ua tus zawm rau. Kuv pom zoo kom nug 'tus neeg mob' tuav lawv txhais caj npab tawm thiab so lub ntsis ntiv tes rau qee yam kom tsis txhob tuav caj npab los ntawm qhov tsis tuaj yeem tuav. Ntshuam 3D luam theej duab rau hauv Meshmixer, thiab siv Plane Cut function los txiav tawm thaj chaw uas koj tsis xav tau, piv txwv li cov ntiv tes, ntiv tes xoo thiab caj npab. Koj kuj tseem xav ua qee qhov kev ntxuav nrog cov cuab yeej txhuam nyob ntawm qhov zoo ntawm koj lub tshuab luam ntawv 3D.

Kauj ruam 2: Rhino 3D

Tom ntej no, ntshuam koj cov qauv txiav caj dab rau hauv Rhino 3D. Siv cov haujlwm MeshtoNURBS los hloov.stl rau hauv polysurface. Tsim kom muaj ntau qhov dav dav dav dav dav dav dav dav kom haum rau qhov ntev ntawm koj tus qauv ntsuas, zoo li cov duab hauv qab no.

Kauj ruam 3:

Tom ntej no, siv txoj haujlwm IntersectTwoSets thiab qhia ua ntej koj lub dav hlau saum npoo av, thiab tom qab ntawd ua qauv caj npab. Koj yuav tsim ntu 'dav hlau txiav' cov nkhaus zoo li cov duab hauv qab no.

Kauj ruam 4:

Qee zaum cov nkhaus no yuav tawm los me ntsis. Siv cov haujlwm _Rebuild ntawm txoj kab nkhaus los kho qhov no. Tom ntej no, siv Loft muaj nuj nqi los tsim lub ntsej muag tshiab uas siv caj npab nkhaus. Koj yuav tsum xaiv qhov nkhaus thiaj li ua haujlwm tau raug.

Kauj ruam 5:

Tom ntej no, siv qhov ua haujlwm OffsetSurf los tsim cov nplais 2 hli saum toj no cov uas twb muaj lawm. Qhov no yuav ua kom ntseeg tau tias tus zauv yuav zaum zoo rau saum daim tawv nqaij. Koj kuj tseem tuaj yeem txiav txoj hlua khi ib nrab los ntawm kev siv Boolean cais cov cuab yeej. Tua Grasshopper rau qib tom ntej. Koj yuav tsum rub lub Voronoi algorithm no thiab qhib nws hauv Grasshopper.

Txhawm rau cov txheej txheem no ua haujlwm raws li tau npaj tseg, koj tseem yuav xav tau ob qho ntxiv ntxiv Weaverbird thiab Millipede. Koj tuaj yeem tau txais lawv ntawm no:

www.dropbox.com/sh/ym0odgl6l134qcx/AADt9iXbDQQJ1hTfqqF97gfJa?dl=0

www.giuliopiacentino.com/weaverbird/

Txoj cai nyem rau thawj Brep cov lus tawm tswv yim ntawm cov txheej txheem thiab xaiv Teeb ib qho Brep thiab nyem rau ntawm thawj ib nrab ntawm txoj hlua thaum thov.

Kauj Ruam 6:

Qhov no yuav tam sim no daim ntawv qhia voronoi tus qauv rau offset caj npab scan. Koj tuaj yeem hla qhov txheej txheem thiab kho qhov sib txawv, suav nrog lub qhov loj thiab ntau dua.

Kauj ruam 7:

Tom qab koj zoo siab nrog qhov tshwm sim, hais txog ntu kawg ntawm cov txheej txheem, nyem txoj cai thiab xaiv Ci.

Kauj ruam 8:

Rov ua cov txheej txheem ntawm lwm qhov ib nrab ntawm txoj hlua tes. Tam sim no koj muaj voronoi brace! Koj yuav tsum tuaj yeem luam tawm qhov sawv ntsug no yam tsis muaj kev txhawb nqa. Koj tuaj yeem siv hlua thiab hlaws los ua lub pob khawm, lossis 3D qauv ntawm pob khawm ntawm koj tus kheej tsim. Xkelet muaj qee qhov kev tsim qauv zoo rau kev tshoov siab. Txaus siab rau!
