GLSL令人困惑，“形状未正确渲染”，“找不到uni吗？”

Question

我正在尝试传递一组顶点及其对应的颜色以进行GL镶嵌混合。我的代码很丑陋，可能有很多错误，但是主要问题是我无法将顶点和颜色数组传递给GLSL。我想知道一种在没有GLSL的情况下做到这一点的方法。谢谢。

我已经尝试不推荐使用非GLSL GL函数，并且没有充分利用我的着色器文件。它似乎不想渲染形状。

main.cpp void'display（）'：

    void display(void)
    {
        //glfwMakeContextCurrent(wavebricks_window);    glLoadIdentity();
        //glTranslatef(1.5f, 0.0f, -7.0f);
        for (int it =0; it<instruments.size();it++){

            alGetSourcef(instruments[it].soundsource, AL_SEC_OFFSET, &tracking);
            instruments[it].currentStep=tracking*(60/tempo);
            instruments[it].currentStep=tracking;

我希望在屏幕上看到可变形状的形状以及它们计算出的顶点和颜色。相反，我什么也没看到。实际上，我正在尝试对三角形进行细分，甚至不知道如何设置3D着色器坐标。请帮忙。
