LWJGL GLSL制服块不起作用

Question

我已经查看了许多教程和示例程序，但我仍然无法弄清楚我的统一块有什么问题。我试图使用viewMatrix渲染一些模型，当它在一个统一块之外时工作正常，但是将统一变量移动到一个块中会导致立方体完全透明。 （尽管如此，它似乎仍然会影响深度测试。）

作为概述，我现在创建一个UBO，将UBO绑定到预先选择的绑定点，然后对统一块执行相同操作。

以下是相关代码：

初​​始化：

Loader loader = new Loader();
Camera camera = new Camera();
MasterRenderer renderer = new MasterRenderer(loader);
renderer.prepareCameraUBO(camera, loader);

相关加载程序代码：

public int createUBO(int floatCount) {
    //Generate UBO
    System.out.println("Generating UBO.");
    int ubo = GL15.glGenBuffers();

    //Resize it and then unbind it
    GL15.glBindBuffer(GL31.GL_UNIFORM_BUFFER, ubo);
    GL15.glBufferData(ubo, floatCount * 4, GL15.GL_DYNAMIC_DRAW);
    GL15.glBindBuffer(GL31.GL_UNIFORM_BUFFER, 0);       
    return ubo;
}

public void bindUBOToPoint(int uboID, int bindingPoint) {
    GL15.glBindBuffer(GL31.GL_UNIFORM_BUFFER, uboID);
    GL30.glBindBufferBase(GL31.GL_UNIFORM_BUFFER, bindingPoint, uboID);
    GL15.glBindBuffer(GL31.GL_UNIFORM_BUFFER, 0);
}

public void updateUBOData(int ubo, int offset, float[] data) {
    GL15.glBindBuffer(GL31.GL_UNIFORM_BUFFER, ubo);
    GL15.glBufferSubData(GL31.GL_UNIFORM_BUFFER, offset, storeDataInBuffer(data));
    GL15.glBindBuffer(GL31.GL_UNIFORM_BUFFER, 0);
}

相关摄像头代码：

public void move(Player player, Loader loader) {
    //We follow the player around and calculate the view matrix
    updateViewMatrixUBO(loader);
}

public void updateViewMatrixUBO(Loader loader) {
    loader.updateUBOData(uboID, 0, VC.convertMatrixToFloatArray(viewMatrix));
}

相关的MasterRenderer代码：

public MasterRenderer(Loader loader) {
    enableCulling();
    createProjectionMatrix();

    entityShader = new EntityShader();
    terrainShader = new TerrainShader();

    entityRenderer = new EntityRenderer(entityShader, projectionMatrix, loader);
    terrainRenderer = new TerrainRenderer(terrainShader, projectionMatrix);
}

public void prepareCameraUBO(Camera camera, Loader loader) {
    //Create a UBO for the camera matrices.     
    int bindingPoint = 0;
    int cameraUBO = loader.createUBO(16);

    loader.bindUBOToPoint(cameraUBO, bindingPoint);

    camera.setUBOID(cameraUBO);

    entityShader.bindUniformBlockToPoint(cameraUBO, bindingPoint, "Camera");
    terrainShader.bindUniformBlockToPoint(cameraUBO, bindingPoint, "Camera");
}

相关着色器程序（Java）代码：

public void bindUniformBlockToPoint(int bindingPoint, String blockName) {
    GL20.glUseProgram(programID);
    GL31.glUniformBlockBinding(programID, GL31.glGetUniformBlockIndex(programID, blockName), bindingPoint);
    GL20.glUseProgram(0);
}

相关着色器（GLSL）代码：

layout (std140, row_major) uniform Camera {
    mat4 viewMatrix;
};
