OpenGL没有正确地模拟模型

Question

我的LWJGL程序存在问题，我尝试纹理的模型看起来很糟糕。我使用光滑加载纹理。

我正在使用的东西： https://www.dropbox.com/sh/3fi9wlq9tt5cey0/AAD7JDh6-KQHLGyHZqjstG6Da?dl=0

有我的渲染代码：

public void render(int id){
    glPushMatrix(); 
    ShaderLoader.start();

    int vertexBuffer = vboVertexBuffers.get(id);
    int textureBuffer = vboTextureBuffers.get(id);
    int textureId = textureIds.get(id);
    int normalBuffer = vboNormalBuffers.get(id);
    int facesAmount = vboFaces.get(id);

    glBindTexture(GL_TEXTURE_2D, textureId);

    glEnableClientState(GL_VERTEX_ARRAY);
    glEnableClientState(GL_TEXTURE_COORD_ARRAY);
    glEnableClientState(GL_NORMAL_ARRAY);

    glBindBuffer(GL_ARRAY_BUFFER, vertexBuffer);
    glVertexPointer(3, GL_FLOAT, 0, 0L);
    glBindBuffer(GL_ARRAY_BUFFER, 0);

    glBindBuffer(GL_ARRAY_BUFFER, textureBuffer);
    glTexCoordPointer(2, GL_FLOAT, 0, 0L);
    glBindBuffer(GL_ARRAY_BUFFER, 0);

    glBindBuffer(GL_ARRAY_BUFFER, normalBuffer);
    glNormalPointer(GL_FLOAT, 0, 0L);
    glBindBuffer(GL_ARRAY_BUFFER, 0);

    glMaterialf(GL_FRONT, GL_SHININESS, 128.f);
    glMaterial(GL_FRONT, GL_DIFFUSE, UtilFloatBuffer.asFloatBuffer(new float[]{0.6f, 0.2f, 0.0f, 0}));

    glDrawArrays(GL_TRIANGLES, 0, facesAmount);

    glBindBuffer(GL_ARRAY_BUFFER, 0);
    glDisableClientState(GL_VERTEX_ARRAY);
    glDisableClientState(GL_TEXTURE_COORD_ARRAY);
    glDisableClientState(GL_NORMAL_ARRAY);

    glBindTexture(GL_TEXTURE_2D, 0);

    ShaderLoader.stop();
    glPopMatrix();
}

并且有部分代码用于加载从Blender导出的模型（带法线等）

try
        {
            while((line = reader.readLine()) != null){
                //parsing
                if(line.startsWith("v ")){
                    float x = Float.valueOf(line.split(" ")[1]);
                    float y = Float.valueOf(line.split(" ")[2]);
                    float z = Float.valueOf(line.split(" ")[3]);
                    m.vertices.add(new Vector3f(x,y,z));
                }
                else if(line.startsWith("vt ")){
                    float x = Float.valueOf(line.split(" ")[1]);
                    float y = Float.valueOf(line.split(" ")[2]);
                    m.textureCoords.add(new Vector2f(x,y));
                }
                else if(line.startsWith("vn ")){
                    float x = Float.valueOf(line.split(" ")[1]);
                    float y = Float.valueOf(line.split(" ")[2]);
                    float z = Float.valueOf(line.split(" ")[3]);
                    m.normals.add(new Vector3f(x,y,z));
                }
                else if(line.startsWith("f ")){
                    Vector3f vertexIndices = new Vector3f(
                            Float.valueOf(line.split(" ")[1].split("/")[0]),
                            Float.valueOf(line.split(" ")[2].split("/")[0]),
                            Float.valueOf(line.split(" ")[3].split("/")[0])
                            );
                    Vector3f textureIndices = new Vector3f(
                            Float.valueOf(line.split(" ")[1].split("/")[1]),
                            Float.valueOf(line.split(" ")[2].split("/")[1]),
                            Float.valueOf(line.split(" ")[3].split("/")[1])
                            );
                    Vector3f normalIndices = new Vector3f(
                            Float.valueOf(line.split(" ")[1].split("/")[2]),
                            Float.valueOf(line.split(" ")[2].split("/")[2]),
                            Float.valueOf(line.split(" ")[3].split("/")[2]));
                    m.faces.add(new Face(vertexIndices, textureIndices, normalIndices));
                }
