Question

我正在使用lvjgl和lvjgui开发程序。尝试显示2D纹理时没有问题，但是当我尝试显示3D立方体时，不会显示所有纹理。这是渲染代码：

@Override
public void render(Context context) {
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
   // glClearColor(0.0f, 0.0f, 0.0f, 0.5f);
    glBegin(GL_QUADS);
    glColor3f(0f, 0f, 1f);
    glVertex3f(0.5f, 0.5f, 0.5f);
    glVertex3f(-0.5f, 0.5f, 0.5f);
    glVertex3f(-0.5f, -0.5f, 0.5f);
    glVertex3f(0.5f, -0.5f, 0.5f);

    glColor3f(1, 0, 1);
    glVertex3f(0.5f, -0.5f, 0.5f);
    glVertex3f(-0.5f, -0.5f,0.5f);
    glVertex3f(-0.5f, -0.5f, -0.5f);
    glVertex3f(0.5f, -0.5f, -0.5f);

    glColor3f(0, 1, 1);
    glVertex3f(0.5f, -0.5f, -0.5f);
    glVertex3f(0.5f, -0.5f, 0.5f);
    glVertex3f(0.5f, 0.5f, 0.5f);
    glVertex3f(0.5f, 0.5f, -0.5f);


    glColor3f(1, 0, 0);
    glVertex3f(0.5f, 0.5f, -0.5f);
    glVertex3f(0.5f, -0.5f, -0.5f);
    glVertex3f(-0.5f, -0.5f, -0.5f);
    glVertex3f(-0.5f, 0.5f, -0.5f);

    glColor3f(1, 1, 0);
    glVertex3f(-0.5f, 0.5f, -0.5f);
    glVertex3f(0.5f, 0.5f, -0.5f);
    glVertex3f(0.5f, 0.5f, 0.5f);
    glVertex3f(-0.5f, 0.5f, 0.5f);

    glColor3f(0, 1, 0);
    glVertex3f(-0.5f, 0.5f, 0.5f);
    glVertex3f(-0.5f, -0.5f, 0.5f);
    glVertex3f(-0.5f, -0.5f, -0.5f);
    glVertex3f(-0.5f, 0.5f, -0.5f);

    glEnd();
    if(rotate)
        glRotatef(0.01f,0.0f,0.5f,0.0f);

}

渲染之前，将执行以下操作：

public RenderingCallback() {
    glMatrixMode(GL_MODELVIEW);
    glLoadIdentity();
    glClearColor(0.0f, 0.0f, 0.0f, 0.5f);
    glClearDepth(0.5f);
    glDepthFunc(GL_LEQUAL);
    glEnable(GL_DEPTH_TEST);
    glShadeModel(GL_SMOOTH);
    glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST);
    glRotatef(20f,0.5f,0.0f,0.0f);
}

多维数据集本身如下所示： Cube

还有video

如您所见，蓝色根本不显示，并且某些纹理相互重叠。如果卸下其中一面，则会出现蓝色的一面。我怎么解决这个问题？我在做什么错了？

Answer 1

您缺少深度缓冲区。在LWJGL初始化中，在调用glfwCreateWindow之前，请提供深度缓冲区的大小：

glfwWindowHint(GLFW_DEPTH_BITS, 16);

您还应该将深度清除为1.0而不是0.5：

glClearDepth(1.0f);

Answer 2

Tnx全部寻求帮助，@ ybungalobill提供解决方案。我添加

glEnable(GL_DEPTH_TEST);

在render(Context context)中无效且问题已解决

简单的多维数据集纹理不显示
