c++ - 在GLFW窗口中启用多重采样不会提高抗锯齿的质量

我已经在GLfW窗口中启用了多重采样，但是输出看起来很奇怪，而不是改善了对象的别名。

当我将Samples设置为0时，这就是结果。


当我将样本设置为8时，这就是结果。


增加样本后，输出将变得更易混淆。

这是代码。

const unsigned int SCR_WIDTH = 800;
const unsigned int SCR_HEIGHT = 600;

void framebuffer_size_callback(GLFWwindow* window, int width, int height);
void processInput(GLFWwindow *window);

float Trianglevertices[] = {
    -0.5f, -0.5f, 0.0f,
    0.5f, -0.5f, 0.0f,
    0.0f,  0.5f, 0.0f
};

int main(int argc, char *argv[])
{
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);
    glfwWindowHint(GLFW_SAMPLES, 8 );  // defined samples for  GLFW Window

    GLFWwindow* window = glfwCreateWindow(SCR_WIDTH , SCR_HEIGHT, "Renderer", nullptr, nullptr);   // Create the render window
    if (window == NULL)
    {
        glfwTerminate();
        return -1;
    }

    glfwMakeContextCurrent(window);
    GLenum GlewInitResult;
    glewExperimental = GL_TRUE;
    GlewInitResult = glewInit();
    if ( GLEW_OK != GlewInitResult)   // Check if glew is initialized properly
    {
        glfwTerminate();
        return -1;
    }

    glEnable(GL_MULTISAMPLE);  // Enabled Multisample
    glEnable(GL_DEPTH_TEST);
    glEnable(GL_BLEND);
    glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
    glBlendEquation(GL_FUNC_ADD);
    LoadShader("C:\\vertex.txt", "C:\\Fragment.txt");
    unsigned int VBOdel, VAOdel;
    glGenVertexArrays(1, &VAOdel);
    glGenBuffers(1, &VBOdel);
    glBindVertexArray(VAOdel);
    glBindBuffer(GL_ARRAY_BUFFER, VBOdel);
    glBufferData(GL_ARRAY_BUFFER, sizeof(Trianglevertices), &Trianglevertices, GL_STATIC_DRAW);
    glEnableVertexAttribArray(0);
    glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 3 * sizeof(GLfloat), (void*)0);
    glBindBuffer(GL_ARRAY_BUFFER, 0);
    glBindVertexArray(0);
    GetShader("TestShader").Use();
    while (!glfwWindowShouldClose(window))
    {
        // input
        // -----
        processInput(window);

        // glfw: swap buffers and poll IO events (keys pressed/released, mouse moved etc.)
        // -------------------------------------------------------------------------------
        glClearColor(0.0, 0.0, 0.0, 1.0);
        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
        ////////////////////////////////////////////////////////////////
        glBindVertexArray(VAOdel);
        glDrawArrays( GL_TRIANGLES, 0, 3);
        glBindVertexArray(0);
        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    // glfw: terminate, clearing all previously allocated GLFW resources.
    // ------------------------------------------------------------------
    glfwTerminate();
    return 0;
}

void framebuffer_size_callback(GLFWwindow* window, int width, int height)
{
    glViewport(0, 0, width, height );
}

void processInput(GLFWwindow *window)
{
    if (glfwGetKey( window, GLFW_KEY_ESCAPE) == GLFW_PRESS)
    {
        QMessageBox  MsgBox;
        MsgBox.setText("EScape Key Pressed");
        glfwSetWindowShouldClose(window, true);
    }
}

最佳答案

经过一番摆弄之后，我终于发现，如果我将“首选图形”处理器更改为“高性能Nvidia处理器”，则在NVidia控制面板中可以管理3D设置，因此可以进行多重采样。

最初将其设置为“自动选择”，并且该应用程序使用的是Integrated Graphics处理器。
