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>
