[1.8] How can i make a sphere?

[Warix]

Hello, I need to make an effect to look like light explosion, I was thinking to make an entity with spehere model, and to render it so it scales its size fast,  so it looks like its exploding.

But I don't know how to make a sphere.

I made a transparent colored sphere for my Magic Beans Mod which as an effect when a certain entity magically appeared. I have described how to render a sphere about halfway down this tutorial page I wrote: http://jabelarminecraft.blogspot.com/p/minecraft-forge-172-quick-tips-gl11-and.html
