问题是我无法弄清楚如何正确绘制两个对象,因为我没有绘制另一个对象.

这是主要代码:

GLuint VertexArrayID;
glGenVertexArrays(1, &VertexArrayID);
glBindVertexArray(VertexArrayID);
GLuint VertexArrayID2;
glGenVertexArrays(1, &VertexArrayID2);
glBindVertexArray(VertexArrayID2);

GLuint programID = LoadShaders( "SimpleVertexShader.vertexshader", "SimpleFragmentShader.fragmentshader" );

GLuint MatrixID = glGetUniformLocation(programID, "MVP");
GLuint MatrixID2 = glGetUniformLocation(programID, "MVP2");

glm::mat4 Projection = glm::perspective(45.0f, 5.0f / 4.0f, 0.1f, 100.0f);
glm::mat4 View       = glm::lookAt(
    glm::vec3(4*2,3*2,8*2),
    glm::vec3(0,0,0),
    glm::vec3(0,1,0)
);
glm::mat4 Model      = glm::translate(glm::mat4(1.0f), glm::vec3(0.0f, 0.0f, 0.0f));
glm::mat4 MVP        = Projection * View * Model;

glUniformMatrix4fv(MatrixID, 1, GL_FALSE, &MVP[0][0]);

glm::mat4 Model2      = glm::translate(glm::mat4(1.0f), glm::vec3(-5.0f, 0.0f, 0.0f));
glm::mat4 MVP2        = Projection * View * Model2; …
