Smooth lines in OpenGL <p>I'm trying to a draw a more-or-less smooth multi-segment line in OpenGL. However I find that if the line is over a thickness about 3 then the joins between the segments are not seamless. They sometimes have gaps between them. Is there a good way of making these joins smooth and gapless? I'm lo... | <p>The most consistent and portable way to draw think lines using OpenGL is to use camera aligned (otherwise know as billboarded) polygons. Different implementations of the OpenGL API handle the end points of the lines differently and <code>GL_LINE_SMOOTH</code> produces drastically different results depending on the ... |
What is the method for optimizing individual functions in a file in GCC 4.1.1? <p>Various C / C++ compilers have <code>#pragma</code>s to control optimization.</p>
<p>For example:</p>
<p><strong>CodeWarrior</strong></p>
<pre><code>#pragma optimization_level 0
void func_no_opt()
{
// Some Work - not optimized
}
... | <p>Looks like the <code>__attribute__((optimize(...)))</code> is the only means to control optimization per-function basis in GCC. Thus with GCC 4.1.1 splitting out a separate library of functions to be optimized is indeed your only option.</p>
