15.2 Kuumba SCP

Mune mamwe mamiriro ezvinhu zvingave zvakakosha kushandura pfungwa yezvakabva, sezvo kusarudza kwehurongwa hwezvinhu zvitsva zvinokweverwa kunogona kutungamirirwa kubva kuSCP itsva. Mukuwedzera, tinogona kuchengetedza hurongwa hwehutano hweMunhu weChristian Coordinate Systems nekupa zita kuti rishandise zvakare sezvakakodzera, sezvatichaona muchitsauko chino.
Kugadzira SCP nyowani isu tinogona kushandisa imwe yeakasiyana sarudzo iyo yemukati menyu yeSCP icon pachayo. Isu tinogona zvakare kudaidza iyo "SCP" murairo unozoratidza sarudzo dzakafanana pahwindo. Isu tinewo chikamu cheribhoni chinonzi "Coordinates", asi chikamu ichi chinongowanikwa mu "Basic 3D Elements" uye "3D Modelling" nzvimbo dzekushanda, sezvaratidzwa pamusoro apa.
Iwe unogona kushandisa chero nzira dzinotungamira kune sarudzo dzeSCP kuraira zvisina kujeka, chero dzichienderana nezvose zviri mukati menyu, ribhoni kana rairo muhwindo. Chero zvazvingava, pakati pezvisarudzo zvinoshandiswa kugadzira UCS itsva, iyo yakapfava, hongu, ndiyo inonzi "Origin", iyo inongokumbira kurongeka kuchava mavambo matsva, kunyange zvazvo hutungamiri hwe X uye Y haishanduki. Zvinofanira kuwedzerwa kuti chiito chimwechete ichi, kushandura nzvimbo yepakutanga uye kugadzira UCS, inogonawo kuwanikwa nekungofambisa icon ne cursor uye kuenda nayo kune imwe nzvimbo itsva, kunyange zvazvo nzira iyi iine dzimwe sarudzo dzatichadzidza. gare gare.

Sezvo zvinonzwisisika, kana zvisikwa zvitsva zvakasimbiswa, uye kubva mazviri, hutungamiri X uye Y yezvimwe zvinhu zvose zvinodudzirwa zvakare. Kuti tidzokere ku Universal Coordinate System (SCU), tinogona kushandisa bhatani rinobatana redhibhoni kana mamiriro emamiriro ezvinhu, pakati pezvimwe zvingasarudzwa.

Kana iyo SCP yatakagadzira ichiratidza mutsva mutsva ichashandiswa nguva dzose, zvino inofanira kunyorwa. Nzira yakakurumidza kuita izvi ndeyokushandisa mamiriro ekutenderera. Iko SCP idzva ikozvino ichaonekwa pane iyo menyu, kunyange zvazvo tinewo muchengeti we SCP uyo achatibvumira kuti tifambe pakati pavo.

Zviripachena, "Origin" handiyo yega murairo wekugadzira SCP. Isu tine mirairo yakasiyana siyana kuitira kuti SCP yedu igone kuchinjirwa kune zvakasiyana zvinodiwa zvekugadzira. Semuenzaniso, sarudzo ye "3 points" inotibvumira kuratidza nzvimbo itsva yekwakabva, asiwo nzira iyo X uye Y ichave yakanaka, saka kutaridzika kwendege yeCartesian kunogona kuchinja.

Isu tinogona zvakare kugadzira UCS inokodzera chimwe chezvinhu zvakadhirowa pachiratidziri. Sarudzo, hongu, inonzi "Chinhu", kunyangwe muchokwadi iyi sarudzo ichanyanya kukosha kwatiri kana tikashanda pazvinhu zve3D.

Dzimwe sarudzo dzekugadzira Personal Coordinate Systems, dzakadai se "Face" kana "Vector Z" dzine chokuita nekudhirowa mu 3D uye dzinobatwa muChikamu cheChisere, kunyanya muchitsauko 34, icho chichatipawo mukana wekudzoka. kubhokisi rehurukuro rataurwa pamusoro apa.
Mumuenzaniso weiyo sketch, zvakatinakira isu kuti tigadzire Yemunhu Coordinate System inogadzirisa kumutsara unoganhura mugwagwa, izvo zvinozotitendera kuve neUCS yakabatana nechinhu chitsva chinodhirowewa. Sezvatatoona, tinogona kushandisa sarudzo "3 points" kana "Object". Zviripachena, izvi zvinoita kuti zvive nyore kudhirowa dhizaini, sezvo zvisingakodzeri kutarisira kurerekera kwemitsara, sezvakaitika kune Universal Coordinate System. Pamusoro pezvo, hazvina kukosha kuti utarise dhirowa "yakarereka" chero, sezvo isu tichigona kutenderedza dhirowa kusvika UCS yave orthogonal kuchiratidziro. Ndizvo zvinoitirwa murairo we "Plant".

Sezvo muverengi achigona kuwedzera, zvinenge zvakakwana kugadzirisa SCU ndokuzoita semiti yekuona kudzorera mufananidzo kunzvimbo yayo yepakutanga.

With vaishandisa zvokushandisa pakuvaka nyore zvinhu, zviri akabatanidza kuti bhuku uye chinhu Tracking, pamwe kugona maturusi Zoom, achitarisira maonero uye nokudzora pachedu Coordonatele, tinogona kutaura kuti tine zvose zvinhu zvinodiwa kukwevera zviri nyore muAustocad, kunyanya munzvimbo ye 2 miviri. Constant tsika, vakawanda ruzivo unyanzvi mufanidzo nharaunda umo uchida kushanda (injiniya kana mapurani, somuenzaniso), kuchaita kuti tive waivako chaizvo zvibereko mubasa redu nyanzvi mumunda. Zvisinei, kunyange zvazvo isu kare tapedza kudzidza ruzivo hunodiwa kuumba mifananidzo pamwe chirongwa ichi, tichiri zvose chokuita fora, kureva, pamwe chete zvayo kunatsiridza. Musoro watinotarisana nawo muchikamu chinotevera.
