use VBO to define color & vertex variable in GPU

[saman_artorious]

I added this to the initialization part:

verticesSize = sizeof(vertices);
colorsSize   = sizeof(colors);
 
glGenBuffers(2, vbods);                       
 
glBindBuffer(GL_ARRAY_BUFFER, vbods[VERTEX]); 
 
glBufferData(GL_ARRAY_BUFFER,
             sizeof(vertices)+sizeof(colors),
             vertices, GL_STATIC_DRAW );
 
glBufferSubData(GL_ARRAY_BUFFER, sizeof(vertices), sizeof(colors), colors);
 
glEnableClientState(GL_VERTEX_ARRAY); 
glEnableClientState(GL_COLOR_ARRAY);

and this to the render part:

glBindBuffer(GL_ARRAY_BUFFER, vbods[VERTEX]);
glVertexPointer(2, QVector3D, 0, 0);   
glColorPointer(3, GL_FLOAT, 0, (GLvoid *) (ANGLE_COUNT * RANGE_COUNT * 6));

though, I get errors in the functions glBufferData, It cannot cast it from QVector3D to GLvoid*, do you have any idea?

vertices is defined as

QVector<QVector3D>

vertices.constData
solved the problem
