Question

我使用顶点数组对象在我的框架中绘制网格。这很好，并且在我的计算机和大多数其他计算机上没有错误，但在某些计算机上（使用OGL 3.2）会出现此错误：

看起来很模糊。我甚至尝试了gDEBugger，但我也找不到任何相关的东西。

我使用Java和lwjgl。

以下是负责创建VAO图纸的代码：

/**
 * Store the mesh's data on the GPU
 */
public void setup() {
    setup = true;
    vaoID = glGenVertexArrays();
    glBindVertexArray(vaoID);

    vboID = glGenBuffers();
    glBindBuffer(GL_ARRAY_BUFFER, vboID);
    /* Create a floatbuffer containing the vertex positions */
    FloatBuffer buffer = BufferUtils.createFloatBuffer(vertices.size()*3).put(vecListToArray3(vertices));
    buffer.flip();
    glBufferData(GL_ARRAY_BUFFER, buffer, GL_STATIC_DRAW);
    /* Set attribute list 0 */
    GL20.glVertexAttribPointer(0, 3, GL_FLOAT, false, 0, 0);

    if (!colors.isEmpty()) {
        colorVboID = glGenBuffers();
        glBindBuffer(GL_ARRAY_BUFFER, colorVboID);
        /* Create a floatbuffer containing the vertex colors */
        buffer = BufferUtils.createFloatBuffer(colors.size()*4).put(vecListToArray4(colors));
        buffer.flip();
        glBufferData(GL_ARRAY_BUFFER, buffer, GL_STATIC_DRAW);
        /* Set attribute list 1 */
        GL20.glVertexAttribPointer(1, 4, GL_FLOAT, false, 0, 0);
    }

    if (!texCoords.isEmpty()) {
        texVboID = glGenBuffers();
        glBindBuffer(GL_ARRAY_BUFFER, texVboID);
        /* Create a floatbuffer containing the texture coords */
        buffer = BufferUtils.createFloatBuffer(texCoords.size()*4).put(vecListToArray4(texCoords));
        buffer.flip();
        glBufferData(GL_ARRAY_BUFFER, buffer, GL_STATIC_DRAW);
        /* Set attribute list 2 */
        GL20.glVertexAttribPointer(2, 4, GL_FLOAT, false, 0, 0);
    }

    if (!normals.isEmpty()) {
        normalVboID = glGenBuffers();
        glBindBuffer(GL_ARRAY_BUFFER, normalVboID);
        /* Create a floatbuffer containing the normals */
        buffer = BufferUtils.createFloatBuffer(normals.size()*4).put(vecListToArray3(normals));
        buffer.flip();
        glBufferData(GL_ARRAY_BUFFER, buffer, GL_STATIC_DRAW);
        /* Set attribute list 2 */
        GL20.glVertexAttribPointer(3, 3, GL_FLOAT, false, 0, 0);
    }

    glBindBuffer(GL_ARRAY_BUFFER, 0);
    glBindVertexArray(0);
}

/**
 * Render the mesh
 * @return 
 */
public Matrix4f draw() {
    if (!setup) {
        Log.fatalError("Mesh not initialized! Call setup before drawing!");
    }
    Matrix4f mvp = Start.container.world.setShaderValues(Graphics.shader);
    glBindVertexArray(vaoID);
    GL20.glEnableVertexAttribArray(0);
    GL20.glEnableVertexAttribArray(1);

    if (!texCoords.isEmpty()) {
        GL20.glEnableVertexAttribArray(2);
    }
    if (!normals.isEmpty()) {
        GL20.glEnableVertexAttribArray(3);
    }

    glDrawArrays(GL_TRIANGLES, 0, vertices.size());
    if (!normals.isEmpty()) {
        GL20.glDisableVertexAttribArray(3);
    }
    if (!texCoords.isEmpty()) {
        GL20.glDisableVertexAttribArray(2);
    }
    GL20.glDisableVertexAttribArray(1);
    GL20.glDisableVertexAttribArray(0);
    glBindVertexArray(0);

    return mvp;
}

为什么这只会导致OGL 3.2出现问题？
