我的纹理渲染有什么问题?

我正在尝试在opengl / processing3中渲染floortiles。

这是我的代码:

 
PImage floorImage;

void setup() {
  size(1200, 600, P3D);
  smooth(8);
  floorImage = loadImage("floor3.png");
}

void draw() {

  background(0);
  ambientLight(255,255,255);
  camera(0.0,100.0,-300.0,mouseX-width/2.0,-(mouseY-height/2.0),0.0,0.0,-1.0,0.0);

  for(int x=-20;x<20;x++)
  {
    for(int z=-20;z<20;z++)
    {
      pushMatrix();
      translate(x*32.0,0.0,z*32.0);
      beginShape();
      textureMode(NORMAL);
      texture(floorImage);
      vertex(-32.0,0.0,-32.0,0.0,0.0);
      vertex(32.0,0.0,-32.0,1.0,0.0);
      vertex(32.0,0.0,32.0,1.0,1.0);
      vertex(-32.0,0.0,32.0,0.0,1.0);
      endShape(CLOSE);      
      popMatrix();
    }
  }
}

这是纹理: tile texture

然而,最终结果看起来很糟糕!

results with artefacts

为什么?

看起来你有四个尺寸= 64,但你在x和z方向上移动了32个。我想你在这里有交叉点。尝试替换为:

#include <string>
