title: Draw only one indicies from IBO
body: <p>How can I correctly to draw only one point from elemets array? Code below draws part of array from 0 to selected.</p>
  
  <pre><code>class Mesh
  {
  public:
  ...
  vector &lt;GLuint&gt; indices;
  ...
  }
  
  void renderSelected(GLuint selectedNum)
  {
      glBindVertexArray(this-&gt;VAO);
      glDrawElements(GL_POINTS, 
      this-&gt;indices[selectedNum] * sizeof(GLuint), 
      GL_UNSIGNED_INT, 
      0;
      glBindVertexArray(0);
  }
  </code></pre>
  
  <p>Something like that everytime draw only one the same point.</p>
  
  <pre><code>    glDrawElements(GL_POINTS, 
      this-&gt;indices[selectedNum] * sizeof(GLuint), 
      GL_UNSIGNED_INT, 
      &amp;this-&gt;indices[selectedNum];
  </code></pre>
