GL_QUADS渲染我不希望它如何

Question

我正在使用LWJGL / Open GL来绘制立方体。问题是它不能以正确的顺序绘制面，并且它不会将立方体渲染到正确的位置！这是Block.java：

            package src;

import static org.lwjgl.opengl.GL11.GL_QUADS;
import static org.lwjgl.opengl.GL11.glBegin;
import static org.lwjgl.opengl.GL11.glColor3f;
import static org.lwjgl.opengl.GL11.glTranslatef;
import static org.lwjgl.opengl.GL11.glVertex3f;

import static org.lwjgl.opengl.GL11.*;

public class Block {
    private float x;
    private float y;
    private float z;
    private Chunk chunk;

public Block(float arg1, float arg2, float arg3, Chunk arg4) {
    x = arg1;
    y = arg2;
    z = arg3;
    chunk = arg4;
}

public void renderBlock() {

    // glTranslatef(0, 0, 0);
    // Texture tx =
    chunk.getWorld().getGame().getTexture(0).bind();
    glBegin(GL_QUADS);
    {
        // Top Face
        glTexCoord2f(0, 0);
        glVertex3f(x - 1, y + 1, z - 1);
        glTexCoord2f(0, 1);
        glVertex3f(x, y + 1, z - 1);
        glTexCoord2f(1, 1);
        glVertex3f(x, y + 1, z);
        glTexCoord2f(1, 0);
        glVertex3f(x - 1, y + 1, z);

        // Bottom Face
        glTexCoord2f(0, 0);
        glVertex3f(x - 1, y, z - 1);
        glTexCoord2f(0, 1);
        glVertex3f(x, y, z - 1);
        glTexCoord2f(1, 1);
        glVertex3f(x, y, z);
        glTexCoord2f(1, 0);
        glVertex3f(x - 1, y, z);

        // Front Face
        glTexCoord2f(0, 0);
        glVertex3f(x, y + 1, z - 1);
        glTexCoord2f(0, 1);
        glVertex3f(x, y, z - 1);
        glTexCoord2f(1, 1);
        glVertex3f(x, y, z);
        glTexCoord2f(1, 0);
        glVertex3f(x, y + 1, z);

        // Back Face
        glTexCoord2f(0, 0);
        glVertex3f(x - 1, y + 1, z - 1);
        glTexCoord2f(0, 1);
        glVertex3f(x - 1, y, z - 1);
        glTexCoord2f(1, 1);
        glVertex3f(x - 1, y, z);
        glTexCoord2f(1, 0);
        glVertex3f(x - 1, y + 1, z);

        // BackFace
        glTexCoord2f(0, 0);
        glVertex3f(x - 1, y + 1, z - 1);
        glTexCoord2f(0, 1);
        glVertex3f(x, y + 1, z - 1);
        glTexCoord2f(1, 1);
        glVertex3f(x, y, z - 1);
        glTexCoord2f(1, 0);
        glVertex3f(x - 1, y, z - 1);

        // FrontFace
        glTexCoord2f(0, 0);
        glVertex3f(x - 1, y + 1, z);
        glTexCoord2f(1, 0);
        glVertex3f(x, y + 1, z);
        glTexCoord2f(1, 1);
        glVertex3f(x, y, z);
        glTexCoord2f(0, 1);
        glVertex3f(x - 1, y, z);

    }
    glEnd();

}

public float getX() {
    return x;
}

public float getY() {
    return y;
}

public float getZ() {
    return z;
}
}

这是Render.java：

    package src;

import static org.lwjgl.opengl.GL11.GL_COLOR_BUFFER_BIT;
import static org.lwjgl.opengl.GL11.GL_DEPTH_TEST;
import static org.lwjgl.opengl.GL11.glClear;
import static org.lwjgl.opengl.GL11.glEnable;
import static org.lwjgl.opengl.GL11.glEnd;
import static org.lwjgl.opengl.GL11.glLoadIdentity;
import static org.lwjgl.opengl.GL11.glPopMatrix;
import static org.lwjgl.opengl.GL11.glPushMatrix;

import java.util.logging.Level;
import java.util.logging.Logger;

import org.lwjgl.LWJGLException;
import org.lwjgl.input.Mouse;
import org.lwjgl.opengl.Display;
import org.lwjgl.opengl.DisplayMode;

public class Render {

Game game;

public Render(Game arggame) {
    game = arggame;
}

public void initDisplay() {
    try {
        Display.setDisplayMode(new DisplayMode(1280, 720));
        Display.create();
    } catch (LWJGLException ex) {
        Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
    }
}

public void renderLoop() {
    glClear(GL_COLOR_BUFFER_BIT);
    glLoadIdentity();

    game.cam.useView();

    glPushMatrix();
    {

        renderBlocks(game.world);

        glEnd();
    }
    glPopMatrix();
    Display.update();

}

public void renderBlocks(World arg1world) {
    for (int i = 0; i < 125; i++) {
        if (arg1world.chunkIndex[i] != null) {
            for (int j = 0; j < 32768; j++) {
                if (arg1world.chunkIndex[i].blockIndex[j] != null) {
                    arg1world.chunkIndex[i].blockIndex[j].renderBlock();
                }
            }
        }
    }
}
}

块似乎比应该更低2个块，我认为它可以通过编辑glVertex3f来修复，但是为什么它不能正确渲染，因为它正在使用位置变量。 glTranslate只是让一切变得更糟（做一些指数转移）。
