Hello.
Is it possible to use STL vector in glDrawArrays?
For example (which does not work):
vector<GLfloat> verts;
verts.push_back(0.0f); verts.push_back(0.0f); verts.push_back(0.0f);
verts.push_back(10.0f); verts.push_back(0.0f); verts.push_back(0.0f);
verts.push_back(0.0f); verts.push_back(10.0f); verts.push_back(0.0f);
void draw_scene()
{
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glEnableClientState(GL_VERTEX_ARRAY);
glVertexPointer(3, GL_FLOAT, 0, verts);
glDrawArrays(GL_TRIANGLES, 0, 3);
glDisableClientState(GL_VERTEX_ARRAY);
glFlush();
}
Instead of (which does work):
GLfloat verts_a[] =
{
0.0f, 0.0f, 0.0f,
10.0f, 0.0f, 0.0f,
0.0f, 10.0f, 0.0f
};
void draw_scene()
{
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glEnableClientState(GL_VERTEX_ARRAY);
glVertexPointer(3, GL_FLOAT, 0, verts_a);
glDrawArrays(GL_TRIANGLES, 0, 3);
glDisableClientState(GL_VERTEX_ARRAY);
glFlush();
}
Probably an old question, but I did not find much about it, hence this post. If it is not possible, then okay. If it is, then I am obviously doing something wrong. Could anyone suggest something please?
Thanks.
