3D立方体尝试出现奇怪的线条

Question

首先是

我对OpenGL和游戏开发都很陌生。也许我会错过一些重要的代码或在我的代码中做了一些可怕的事情。请随时在评论中询问更多信息。

问题

我试图用单线画出一个3D立方体。它按预期工作，但出现奇怪的行 奇怪的行从 0,0,1 移动到 1,1,0

我用不同的（纯色）颜色着色我的线条。 怪异的行有一个渐变。

好的，某些代码的时间

由于这是很多代码，我会尝试发布最小值。正如我之前所说，随时可以要求更多。

绘制我的多维数据集的方法

private void drawBlock(Position pos) {
    int x = pos.x, y = pos.y, z = pos.z;

    GL11.glBegin(GL11.GL_LINE_STRIP);

    GL11.glColor4f(1, 1, 1, 1);
    // 0,0,0 -> 5,0,0
    GL11.glVertex3i(x, y, z);
    GL11.glVertex3i(x + blockSize, y, z);

    // 0,0,0 -> 0,5,0
    GL11.glVertex3i(x, y, z);
    GL11.glVertex3i(x, y + blockSize, z);

    // 0,0,0 -> 0,0,5
    GL11.glVertex3i(x, y, z);
    GL11.glVertex3i(x, y, z + blockSize);


    GL11.glColor4f(0.1f, 0.5f, 0.5f, 1);
    // 5,0,5 -> 0,0,5
    GL11.glVertex3i(x + blockSize, y, z + blockSize);
    GL11.glVertex3i(x, y, z + blockSize);

    // 5,0,5 -> 5,5,5
    GL11.glVertex3i(x + blockSize, y, z + blockSize);
    GL11.glVertex3i(x + blockSize, y + blockSize, z + blockSize);

    // 5,0,5 -> 5,0,0
    GL11.glVertex3i(x + blockSize, y, z + blockSize);
    GL11.glVertex3i(x + blockSize, y, z);


    GL11.glColor4f(0.9f, 0.25f, 0.25f, 1);
    // 0,5,5 -> 0,0,5
    GL11.glVertex3i(x, y + blockSize, z + blockSize);
    GL11.glVertex3i(x, y, z + blockSize);

    // 0,5,5 -> 5,5,5
    GL11.glVertex3i(x, y + blockSize, z + blockSize);
    GL11.glVertex3i(x + blockSize, y + blockSize, z + blockSize);

    // 0,5,5 -> 0,5,0
    GL11.glVertex3i(x, y + blockSize, z + blockSize);
    GL11.glVertex3i(x, y + blockSize, z);

    GL11.glColor4f(1, 0.75f, 0, 1);
    // 5,5,0 -> 5,0,0
    GL11.glVertex3i(x + blockSize, y + blockSize, z);
    GL11.glVertex3i(x + blockSize, y, z);

    // 5,5,0 -> 0,5,0
    GL11.glVertex3i(x + blockSize, y + blockSize, z);
    GL11.glVertex3i(x, y + blockSize, z);

    // 5,5,0 -> 5,5,5
    GL11.glVertex3i(x + blockSize, y + blockSize, z);
    GL11.glVertex3i(x + blockSize, y + blockSize, z + blockSize);

    GL11.glEnd();
}

OpenGL初始化

public void init3D() {
    GL11.glMatrixMode(GL11.GL_PROJECTION);
    GL11.glLoadIdentity();

    GLU.gluPerspective((float) 100, width / height, 0.001f, 1000);
    GL11.glMatrixMode(GL11.GL_MODELVIEW);

    GL11.glEnable(GL11.GL_TEXTURE_2D);
    GL11.glShadeModel(GL11.GL_SMOOTH);
    GL11.glClearColor(0.0f, 0.0f, 0.0f, 0.5f);
    GL11.glClearDepth(1.0f);
}

Answer 1

你应该使用GL11.glBegin(GL11.GL_LINES);而不是线条，

line_strip是连接线的序列，其中序列P1，P2，P3，P4给出线P1-P2，P2-P3，P3-P4等，而GL_LINES仅给出P1-P2和P3-P4
