Ok so I'm creating a game in Directx and I want to create my terrain using heightmaps... I've managed to create an area using the x and z axis but I can't seem to load the heightmap properly for it to add the values into the y axis. I'm using visual studio.net 2003 c++, I'll show the code that I've got for loading the RAW file in: bool GObject::ReadRAWfile(const char *RAWName) { std::vector<BYTE> in(NumVertices); std::ifstream inFile(RAWName, std::ios_base::binary); if( inFile == 0) return false; inFile.read((char*)&in[0], in.size()); inFile.close(); m_heightmap.resize(NumVertices); for(int i = 0; i < in.size(); i++) m_heightmap = in; return true; } m_heightmap is a std::vector<int> declared in my class function. The program runs but when I debug it it doesn't seem to be loading in the data, as my m_heightmap remains empty after the for loop at the end. I have no idea why it isn't working. Can Someone please help

Just use D3DX to load it up as textures. There is no point anyway in writing code to read a file format.

I would but unfortunately this is for a project and I'm not allowed to use D3DX as it does all of the work for you and the terrain will play a major part in my game.

My terrain system is about 1100 lines of code, of which approximately 10 are dedicated to loading the heightmap from file.

Hardly "all" the work.

I suppose your's is a much more complex terrain system, I just don't understand why mine doesn't load the file
