    Access violation in C++

    I have been trying to resolve the access violation in the program for bounding volume hierarchy. Which takes an 3-D object "statue.ply" and creates a bounding volume hierarchy through which a ray tracer is used. I get an access violation error while running it. I have used SDL and lib3d packages.
    I'm using visual studio 2010 on windows 7

    >Error: Unhandled exception at 0x00fa2e80 in bvh.exe: 0xC0000005: Access violation reading location 0x00000004.

    Call Stack :> `bvh.exe!Triangle::Triangle(const Vertex * vertexA, const Vertex * vertexB, const Vertex * vertexC, unsigned int r, unsigned int g, unsigned int b, bool twosided, bool triNormalProvided, Float3 triNormal)` Line 393 + 0x150 bytes C++

    here is the link to my code [c++] BVH_SAH - Pastebin.com
    can anyone help with it.

    Thank you

    You haven't posted your code. Also, you claim this is C++, so why did you post in the C section?

    Outside of your DOS world, your header file is meaningless.

    Apparently not?


    Quzah.
    Hope is the first step on the road to disappointment.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
