title: Changing text size of 3d plot, R
body: <p>I have a problem changing the text size of a 3d plot I generated with the package rgl. Everything works fine, but I can't effectively change the cex and size properties of an 3d object when rendering it in shiny, with the renderWebGL</p>
  
  <pre><code>library(rgl)
  
  plot3d(x, y, z, xlab ="x", ylab ="y", zlab ="z")
  texts3d(x, y, z, rownames(data))
  </code></pre>
  
  <p>Any help is highly appreciated! Best Regards.</p>
