无法使 opengl 纹理正常工作

我正在尝试用vbos绘制一个简单的立方体。但是当我运行我的程序时，我没有得到预期的结果。而有纹理时，我的立方体是完全不透明的，我的纹理只有一种颜色......

你可以在下面看到我的代码：

使用 SFML 加载纹理：

void Grass::load() {
sf::Image texture;
if (!texture.loadFromFile(path_m))
std::cerr << "Error while loading texture : " << path_m << std::endl;
else {
glGenTextures(1, &id_m);
glBindTexture(GL_TEXTURE_2D, id_m);
{
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, texture.getSize().x,
texture.getSize().y, 0, GL_RGBA, GL_UNSIGNED_BYTE,
texture.getPixelsPtr());
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
}
glBindTexture(GL_TEXTURE_2D, 0);
}
}

立方体顶点的生成：

void Chunck::generate() {
{
std::vector vec = { -1.0, -1.0, -1.0, 1.0, -1.0, -1.0, 1.0, 1.0, -1.0, // Face 1
-1.0, -1.0, -1.0, -1.0, 1.0, -1.0, 1.0, 1.0, -1.0,     // Face 1
1.0, -1.0, 1.0, 1.0, -1.0, -1.0, 1.0, 1.0, -1.0,       // Face 2
1.0, -1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, -1.0,         // Face 2
-1.0, -1.0, 1.0, 1.0, -1.0, 1.0, 1.0, -1.0, -1.0,      // Face 3
-1.0, -1.0, 1.0, -1.0, -1.0, -1.0, 1.0, -1.0, -1.0,    // Face 3
-1.0, -1.0, 1.0, 1.0, -1.0, 1.0, 1.0, 1.0, 1.0,        // Face 4
-1.0, -1.0, 1.0, -1.0, 1.0, 1.0, 1.0, 1.0, 1.0,        // Face 4
-1.0, -1.0, -1.0, -1.0, -1.0, 1.0, -1.0, 1.0, 1.0,     // Face 5
-1.0, -1.0, -1.0, -1.0, 1.0, -1.0, -1.0, 1.0, 1.0,     // Face 5
-1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, -1.0,         // Face 6
-1.0, 1.0, 1.0, -1.0, 1.0, -1.0, 1.0, 1.0, -1.0 };     // Face 6
vertices_m.insert(vertices_m.begin(), vec.begin(), vec.end());
}
{
std::vector vec = {0, 0,   1, 0,   1, 1,     // Face 1
0, 0,   0, 1,   1, 1,     // Face 1
0, 0,   1, 0,   1, 1,     // Face 2
0, 0,   0, 1,   1, 1,     // Face 2
0, 0,   1, 0,   1, 1,     // Face 3
0, 0,   0, 1,   1, 1,     // Face 3
0, 0,   1, 0,   1, 1,     // Face 4
0, 0,   0, 1,   1, 1,     // Face 4
0, 0,   1, 0,   1, 1,     // Face 5
0, 0,   0, 1,   1, 1,     // Face 5
0, 0,   1, 0,   1, 1,     // Face 6
0, 0,   0, 1,   1, 1};    // Face 6
texture_m.insert(texture_m.begin(), vec.begin(), vec.end());
}
}

立方体绘图：

void Chunck::draw() const {
glBindBuffer(GL_ARRAY_BUFFER, vboID_m);

glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 0, BUFFER_OFFSET(0));
glEnableVertexAttribArray(0);
glVertexAttribPointer(2, 2, GL_FLOAT, GL_FALSE, 0, BUFFER_OFFSET(vertices_m.size() * sizeof(double)));
glEnableVertexAttribArray(2);
glBindTexture(GL_TEXTURE_2D, grassTexture_m.getID());
glDrawArrays(GL_TRIANGLES, 0, vertices_m.size());
glBindTexture(GL_TEXTURE_2D, 0);
glDisableVertexAttribArray(2);
glDisableVertexAttribArray(0);

glBindBuffer(GL_ARRAY_BUFFER, 0);
}

将立方体加载到 VBO 中：

void Chunck::load() {
grassTexture_m.load();
if (glIsBuffer(vboID_m) == GL_TRUE)
glDeleteBuffers(1, &vboID_m);
glGenBuffers(1, &vboID_m);
glBindBuffer(GL_ARRAY_BUFFER, vboID_m);
{
glBufferData(GL_ARRAY_BUFFER, (vertices_m.size() + texture_m.size()) * sizeof(float), 0,
GL_STATIC_DRAW);
glBufferSubData(GL_ARRAY_BUFFER, 0, vertices_m.size() * sizeof(float), vertices_m.data());
glBufferSubData(GL_ARRAY_BUFFER, vertices_m.size() * sizeof(float),
texture_m.size() * sizeof(float), texture_m.data());
}
glBindBuffer(GL_ARRAY_BUFFER, 0);
}
