Yakagadziriswa: lerp

Linear Interpolation, inonyanya kuzivikanwa seLerp, inzira inoshandiswa kuverenga poindi iri pakati pemamwe mapoinzi maviri pamutsetse kana curve. Iyi tekinoroji inoshandiswa zvakanyanya munzvimbo dzakasiyana senge magirafu emakomputa uye kuvandudzwa kwemutambo. Muchikamu chino, tichanyura mukati mekuti Lerp chii uye kuti tingaite sei muJava.

Lerp izwi remasvomhu rinomirira kududzira mutsetse. Iyo inzira yekugadzira kukosha kubva kune mbiri dzinozivikanwa kukosha, yakapihwa chikamu chepakati pakati pezviviri. Izvi zvinogona kunzwika zvakaoma, asi ichokwadi pfungwa iri nyore. Linear kududzira kunowanzo shandiswa mumakomputa magirafu kufungidzira data uko pasina ruzivo rwakakwana, uye mukuvandudza kwemutambo, kugadzira yakapfava animation uye shanduko.

public class Lerp {
  public static float lerp(float point1, float point2, float fraction) {
    return (1 - fraction) * point1 + fraction * point2;
  }
}

Kunzwisisa Basa reLerp

Kuti unzwisise zviri nani Lerp inoshanda, basa iri rinotora maparameter matatu: point1 uye point2, inomiririra mbiri mbiri dzinozivikanwa dzatakambotaura, uye chikamu, chinomiririra nhambwe yepakati pakati pemapoinzi maviri. Mhedzisiro ipfungwa nyowani inorara pachikamu chemutsara chinobatanidza mapoinzi maviri, zvichienderana nenhambwe yepakati.

Basa racho riri nyore uye rinoshanda sezvinotevera:
1. Inotanga kuverenga chinhambwe kubva papoint1 kusvika painoperera (kana point1 ichitorwa sepanotangira), sekunge chikamu chinomiririra chikamu chechikamu chemutsara wese.
2. Inobva yaverenga chinhambwe kubva panotangira kusvika painodiwa.
3. Pakupedzisira, inowedzera aya madaro maviri pamwechete kuti awane mhedzisiro yekupedzisira.

Ngationgororei izvi nemuenzaniso:

public class Main {
  public static void main(String[] args) {
    float point1 = 1.0f;
    float point2 = 2.0f;
    float fraction = 0.5f;
    float result = Lerp.lerp(point1, point2, fraction);
    System.out.println("The interpolated point is: " + result);
  }
}

Java Libraries for Interpolation

Nepo Java isina raibhurari yakavakirwa-mukati yekududzira, kune akati wandei echitatu-bato maraibhurari anopa rutsigiro rwakakwana rwemhando dzakasiyana dzekupirikira, kusanganisira mutsara kududzira. Iyo Apache Commons Math raibhurari imwe yakadaro raibhurari inopa huwandu hwakawanda hwemabasa emasvomhu, kusanganisira akati wandei akasiyana nzira dzekududzira.

Imwe sarudzo yakakurumbira ndeye Jzy3d raibhurari ye 3D mifananidzo, iyo inopa maturusi emutsara uye asina-mutsara kududzira pakati pezvimwe zvinhu.

mhedziso

Linear kududzira (Lerp) chishandiso chine simba muminda yakawanda inosanganisira animation uye kuvandudzwa kwemitambo, mifananidzo yemakomputa, fizikisi, uye nhamba, kungotaura zvishoma. Takaongorora pfungwa yayo yekutanga, kuti inoshanda sei, uye kuti ingaitwe sei muJava. Uku kungokwenya pamusoro, sezvo Lerp inogona zvakare kukwidziridzwa ku2D uye 3D, izvo zvinoita kuti ive yakanyanya simba chishandiso. Rangarira, kudzidzira ndiyo kiyi yekuziva chero pfungwa, saka ramba uchikodha uye kuyedza!
