Iphone 在二维图像cocos3d上绘制网格

嗨，朋友们，我想在2d图像上绘制网格，如下图所示，下面我已经给出了代码，但应用程序正在崩溃，并且没有显示错误消息…因此很难识别问题

    float arr_location[] = {0.0,0.0,0.0,  0.0,1.0, 0.0,  1.0,1.0,0.0, 1.0,0.0,0.0};

CC3VertexLocations* Vlocation = 
    [[CC3VertexLocations vertexArrayWithName:@"demoLocation"] retain];
Vlocation.drawingMode = GL_TRIANGLES;//
Vlocation.vertexCount = 3;
Vlocation.vertices = arr_location;

    float arr_normal[] = {0.0,0.0,-1.0};
CC3VertexNormals* normal = [[CC3VertexNormals vertexArrayWithName:@"demoNormal"] retain];
normal.vertexCount = 1;
normal.vertices = arr_normal;

    float arr_indice[] = {0,1,2};
CC3VertexIndices* demoIndices = [CC3VertexIndices vertexArrayWithName: @"demoIndicies"];
demoIndices.drawingMode = GL_TRIANGLES;
demoIndices.vertexCount = 3;
demoIndices.vertices = arr_indice;

CC3VertexArrayMesh* demoMeshModel = 
     [[CC3VertexArrayMesh meshWithName:@"demoMeshModel"] retain];
demoMeshModel.vertexLocations = Vlocation;
demoMeshModel.vertexNormals = normal;
demoMeshModel.vertexIndices = demoIndices;

CC3PlaneNode *meshNode = [[CC3PlaneNode alloc] init];
meshNode.mesh = demoMeshModel;
meshNode.material = [CC3Material shiny];
meshNode.texture = [CC3Texture textureFromFile: @"2.jpg"];

[self addChild: meshNode];

我认为cocos2d不可能做到这一点，它看起来像3D实际上，你可以用OpenGL ES做到这一点，虽然我不确定具体如何，但还没有在如此低的级别上工作，但是如果你可以使用，那么使用

CC3PlaneNode

并将图片设置为纹理就相当容易了。我建议您阅读并再次询问是否还有其他问题
