Mavara Matope Akaitwa Sei
Ichi chinyorwa ndicho chikamu chechipiri munyaya yedu pamusoro pekubuda . Chikamu chokutanga chinosanganisira kusika urongwa hweUV ye 3D model. Iye zvino tava kutarisa mavara mapping.
Saka Saka Mapepa Anoita Sei?
Mepu yekunyora ibhizimisi remafananidzo maviri rinogona kushandiswa kumusoro kwe 3D model kuti awedzere ruvara, mavara, kana zvimwe zvakasarudzwa pamusoro pepamusoro seguruva, reflectivity, kana pachena. Mavara emagetsi anosimbiswa kuti aenzane zvakananga nehutano hweUV hwemufananidzo waMwari usina kubvongodzwa uye unofungidzirwa kubva pamifananidzo chaiyo-yeupenyu, kana kuti akaiswa mufananidzo wekushanda kwakafanana na Photoshop kana Corel Painter.
Mavara emagetsi anowanzopwa zvakananga pamusoro pekuenzaniswa kwemufananidzo weUV, iyo inogona kutengeswa sekwereti bitmap mufananidzo kubva kune chero 3D software software . Matongi artists anowanzoshanda mumatare akacheka, nehutano hweUV pane imwe nhepfenyuro-yakasviba iyo mufananidzo achashandisa semuongorori wekuisa nzvimbo yakananga.
Ruvara (kana Kupararira) Mepu
Sezvo zita racho raizoreva, kushandiswa kwakajeka kwemapupa ekunyora ndiko kuwedzera ruvara kana kumira kumusoro kwemuenzaniso . Izvi zvinogona kunge zvakajeka sekushandisa huni hwehuni hunoenda kune tafura pamusoro, kana kuti yakaoma semapu emavara emutambo wose wemutambo (kusanganisira zvombo uye zvinhu).
Kunyange zvakadaro, izwi remapuraneti mapepa , sezvo rinowanzoshandiswa ishoma yemasomarasi-pamusoro pemapupu anotamba basa guru mumakombiyuta mafirimu kunze kwemavara uye maratidziro. Muchigadzirwa chekugadzirwa kwemashizha, unhu kana kuti mapepa emagara ezvakatipoteredza inowanzova imwe yemapu matatu ayo achashandiswa kunenge imwe yega yega 3D model.
Mamwe mairi maviri "anokosha" mapepa mapepa anonyatsoratidza mamapu uye bump, displacement, kana mapeji akajeka.
Specular Maps
Specular maps (inozivikanwawo semapupa emagetsi). Mepu inonyatsotsanangurira inotaurira software iyo zvikamu zvemuenzaniso zvinofanira kuve zvakajeka kana kujeka, uyewo ukuru hwegwinya. Zvinyorwa zvinyorwa zvinotumidzwa kuti iyo inopenya, yakafanana nesimbi, ceramics, uye mamwe mapurasitiki anoratidza simba rakasimba rinonyanya kujekesa (kuratidzwa kwakananga kubva kune chiedza chakasimba). Kana usina chokwadi pamusoro pezvinhu zvinonyanya kufungidzirwa, tsvaga mutsvuku wekuyerera pamucheka we mugayi wako wekase. Chimwe chimiro chinowanzoonekwa chekufungidzira kwakajeka ndechechidiki chechichena mumeso eumwe, pamusoro pemudzidzi.
Mepu inonyatsoratidzika inowanzoita chimiro chegiryscale uye inonyanya kukosha kune nzvimbo dzisina kufanana zvakajeka. Imotokari yakadzivirirwa, somuenzaniso, inoda mepu inonyatsorongeka kuitira kuti zviputi, maziso, uye kusakwana zvipfeke muzvombo zvingagutsikana. Saizvozvowo, mutambo unoitwa nezvinhu zvakasiyana-siyana unoda mapepa anonyatsotarisa kuti ataure matanho akasiyana-siyana ekupenya pakati peganda reunhu, simba resimbi buckle, uye zvokupfeka.
Bump, Displacement, kana Mapoka Anowanikwa
Zvimwe zvakaoma kupfuura zvimwe zvemuenzaniso miviri yapfuura, mapoka emamapu ndiwo rudzi rwemapupa emagetsi anogona kubatsira kupa zvinonyatsooneka zvinokonzera matambudziko kana kuora pamusoro pemuenzaniso.
Chimbofunga rusvingo rwezvidhinha: Chifananidzo chesvingo rwezvidhina chinogona kuiswa pamapuraneti ane pombi uye yakadanwa kupera, asi mikana haingazoiti seyakanyatsogutsikana mune shanduro yekupedzisira. Izvi ndechokuti ndege yakadzika haifaniri kugadziriswa pakuchenesa nenzira imwechete yegadziro rezvidhinha, pamwe nekuputika kwayo uye kubata.
Kuti uwedzere mafungiro ezvokwadi, bump kana mapeji chaiwo aigona kuwedzerwa kuti awedzere kunyatsogadzirisa zvakare, yakawanda pamusoro penzvimbo yezvidhinha, uye kuwedzera kufungidzira kuti kuputika pakati pezvidhinha kuri kunyatsokwira munzvimbo. Zvechokwadi, zvingave zvichikwanisika kuti zvive nemigumisiro yakafanana nekuenzanisa chimwe nechimwe chezvidhinha nemaoko, asi ndege yakarongeka yakarongeka inonyanya kuenzanisa. Hazvibviri kudarika kukosha kwemapupa akajairika mumasikati emakambani emitambo-mitambo yakange isingagoni kutarisa nzira yavanoita nhasi pasina makarasi akajeka.
Bump, kutendeuka, uye makarasi akajeka ari kukurukurirana ivo voga uye inonyanya kukosha pakuzadzikisa mufananidzo-muzvinyorwa.
Iva wakatarisira nyaya inodzifukidza iyo zvakadzika.
Mamwe Mepu Mhando Yokuziva
Kunze kweizvi mapoka matatu mapepa, pane imwe kana maviri iwe wauchaona kakawanda:
- Reflection Map: Anoudza software iyo zvikamu zve 3D model zvinofanira kuratidza. Kana iyo yose yemufananidzo yepamusoro ichiratidzira, kana kana chiyero chekufungidzira chiri chimiro chinyorwa chekuratidzira chinowanzosiyiwa. Kufungisisa kwemashoko kune mifananidzo yakajeka, uye yakasviba inoratidza 0% reflectivity uye white white inoratidza 100% kufungidzira pamusoro.
- Kusanyatsonzwisisa Mepu: Zvakanyatsofanana nemepu yekuratidzira, kunze kwekuti inoudza software iyo zvikamu zvemuenzaniso zvinofanira kuva pachena. Kushandiswa kwakawanda kwemepu yepachena kwaizova nzvimbo yaizove yakanyanya kuoma, kana kuti yakawandisa yakawanda inodhura kudzokorora, seketani yekuvhara fence. Kushandisa kujekesa, panzvimbo yekuenzanisira hutano humwe kunogona kunge hunovimbisa chero bedzi mufananidzo wacho usingatauri pedyo nechepamberi, uye unoshandisa zvishoma ma polygoni.
Takatarisa kuumba nekugadzira kunze kweVs uye takaenda kumarudzi akasiyana emapupa epamusoro anogona kushandiswa ku 3D model. Iwe uri nani munzira yako yekukwira yako 3D model!
