Hi to all.

I am a newbie to graphics programming and I really need some expert help. I am working under opengl. I wanted to create a 2D cloud simulator. So I used a Perlin noise function to create an initial cloud image. For every pixel there was color I created a particle with the equivalent indexes. I also created a fluid Simulator for solving the necessary equations and calculating the new positions of my cloud particles. The result is the following Image ::

As you can see there are holes between the particles. So I used render-to-texture and blurred the initial image. But I don't really like the result, and I was wondering if there is any other method I could use.

Thanx in advance for any reply.
