    <p>I'm using an algorithm to generate quads. These become outlines. The algorithm is:</p> <pre><code> void OGLENGINEFUNCTIONS::GenerateLinePoly(const std::vector&lt;std::vector&lt;GLdouble&gt;&gt; &amp;input, std::vector&lt;GLfloat&gt; &amp;output, int width) { output.clear(); if(input.size() &lt; 2) { return; } int temp; float dirlen; float perplen; POINTFLOAT start; POINTFLOAT end; POINTFLOAT dir; POINTFLOAT ndir; POINTFLOAT perp; POINTFLOAT nperp; POINTFLOAT perpoffset; POINTFLOAT diroffset; POINTFLOAT p0, p1, p2, p3; for(unsigned int i = 0; i &lt; input.size() - 1; ++i) { start.x = static_cast&lt;float&gt;(input[i][0]); start.y = static_cast&lt;float&gt;(input[i][1]); end.x = static_cast&lt;float&gt;(input[i + 1][0]); end.y = static_cast&lt;float&gt;(input[i + 1][1]); dir.x = end.x - start.x; dir.y = end.y - start.y; dirlen = sqrt((dir.x * dir.x) + (dir.y * dir.y)); ndir.x = static_cast&lt;float&gt;(dir.x * 1.0 / dirlen); ndir.y = static_cast&lt;float&gt;(dir.y * 1.0 / dirlen); perp.x = dir.y; perp.y = -dir.x; perplen = sqrt((perp.x * perp.x) + (perp.y * perp.y)); nperp.x = static_cast&lt;float&gt;(perp.x * 1.0 / perplen); nperp.y = static_cast&lt;float&gt;(perp.y * 1.0 / perplen); perpoffset.x = static_cast&lt;float&gt;(nperp.x * width * 0.5); perpoffset.y = static_cast&lt;float&gt;(nperp.y * width * 0.5); diroffset.x = static_cast&lt;float&gt;(ndir.x * 0 * 0.5); diroffset.y = static_cast&lt;float&gt;(ndir.y * 0 * 0.5); // p0 = start + perpoffset - diroffset //p1 = start - perpoffset - diroffset //p2 = end + perpoffset + diroffset // p3 = end - perpoffset + diroffset p0.x = start.x + perpoffset.x - diroffset.x; p0.y = start.y + perpoffset.y - diroffset.y; p1.x = start.x - perpoffset.x - diroffset.x; p1.y = start.y - perpoffset.y - diroffset.y; p2.x = end.x + perpoffset.x + diroffset.x; p2.y = end.y + perpoffset.y + diroffset.y; p3.x = end.x - perpoffset.x + diroffset.x; p3.y = end.y - perpoffset.y + diroffset.y; output.push_back(p2.x); output.push_back(p2.y); output.push_back(p0.x); output.push_back(p0.y); output.push_back(p1.x); output.push_back(p1.y); output.push_back(p3.x); output.push_back(p3.y); } } </code></pre> <p>The problem is that there are then gaps as seen here: <a href="http://img816.imageshack.us/img816/2882/eeekkk.png" rel="nofollow noreferrer">http://img816.imageshack.us/img816/2882/eeekkk.png</a></p> <p>There must be a way to fix this. I see a pattern but I just cant figure it out. There must be a way to fill the missing inbetweens. Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
