Having Problems With C DirectX Terrain?

Lesson 12. Restless clouds

I try if you need to render terrain with DirectX 20 and apply a heightmap to this tool.I load the heightmap, then copy it to an integer vector and for each vertex position I assign the value of the heightmap to the y position of the vertex, the terrain is also completely destroyed and also distorted. If I remove the y-axis calculations, I design a flat grid and there is no dilemma.

bool cGrid::readRawFile(std::string fileName, int m, n) int // Degree of elevation for each vertex    std::vector in(m*n);    std::ifstream inFile(fileName.c_str(), std::ios_base::binary);    (! in file) provided that the return is false;    inFile.read(        (char*)&in[0], // buffer        to size()); // number of bytes to read from buffer   inFile.close();   // Duplicate the BYTE vector into an int vector    m_heightmap.resize(n*m);    (integer for i = 0; document < in.size(); i++)        m_heightmap[i] matches in[i];    restore the truth;for (size_t i 0; = i

HRESULT cGrid::CreateGrid(float width, stream depth, UINT n, UINT m){    hours HRESULT;    interval vertexCount = m*n;    UINT faceCount is(m - 1)*(n - 1) 2 . 2; // Each quad is made up of two triangles    positioned as half width = 0.5f*width;    go half depth = 0.5 f*depth;    // projects the mesh onto the xz plane    arranged dx = width / (n - 1);    go dz = depth / - (m 1);    float du is 1.0f/(n - 1); // surface coordinates   swimmer's dv u003d 1.0 lb / (m - 1);    m_Mesh.m_Vertices.resize(vertex counter);    // create arbitrary mesh vertices, including most normals and tangent,    // Then you can create a specific cross product bitanget for regular days -_-    when it comes to (UINT i = 0; i < m; ++i anyway).            float z = half depth - i*dz; // Reset For Near Cell        for (UINT r = 0; j < n; ++j)                    float x = -halfWidth + j*dx;            float y = (float)m_heightmap[j + i*m];            m_Mesh.m_Vertices[i*n + j].Position = XMFLOAT3(x, y, z);// m_Mesh.m_Vertices[i*n + j].Normal corresponds to XMFLOAT3(0.0f, 1.0f, 0.0f);// m_Mesh.m_Vertices[i*n + j].TangentU = XMFLOAT3(1.0f, 0.0f, 0.0f);            // Stretch the texture instead of the mesh.            m_Mesh.m_Vertices[i*n + j].TextureCords.x = j*du;            m_Mesh.m_Vertices[i*n + j].TextureCords.y means i*dv;                m_Mesh.m_Indices.resize(faceCount 4 . 3); // 3 indexes for each page    // Repeat each guess and quadruple   index.
