Hi, This is part of my vector class:

CVector(float newX=0.0f, float newY=0.0f, float newZ=0.0f)
	{ x=newX;	y=newY;		z=newZ; }
	CVector(const CVector &rhs)
	{ x=rhs.x;	y=rhs.y;	z=rhs.z; }
	~CVector() {}

this is how I define a vertex position:

CVector position;

and this is how I use it:

		glVertexPointer(3, GL_FLOAT, sizeof(vertex_t), position);

however I cannot use this CVector here:

error C2664: ''glVertexPointer'' : cannot convert parameter 4 from ''CVector'' to ''const GLvoid *''

I understand... but how can I make something like this work? Thanks

Well, as the name implies, glVertexPointer() expects a pointer to a vertex array. So you should do something like this:


CVector *positions = new CVector[...]

glVertexPointer(3, GL_FLOAT, sizeof(vertex_t), positions);

Or use a fixed size array instead.
