often a vertex is used by models, for example a cube has vertexes (8), and you could move it around with vectors

vertexes often have more infos than just x,y,z, for example a color, or texture coordinates, or even a normal-vector "on it", for lighting-calculations



we wanna play, not watch the pictures

ohh. and vectors are mathematical defined things

vertexes are just things, programmers have defined themselfes

though they mean mathmatically different things u normally use the same class for them in 3d grafixs, i normally call everything in me program VECTORS even though some are vertices if u wanna be a bit more correct u could go

struct VECTOR{
float x,y,z;

VECTOR (float xx, float yy, float zz) { x=xx; y=yy; z=zz; }
VECTOR operator+(VECTOR &pVec) { return VECTOR(x + pVec.x, y + pVec.y, z + pVec.z);}

};

typedef VECTOR VERTEX;

VERTEX point(0,0,0);
VECTOR velocity(0,10,10);

VERTEX newposition = point+velocity;
