Day 48: Perturbing

From the previous post, I managed translation with two bitmap textures to give the impression of a cloudy environment. Did these look nice? Kinda, but what about SPECTACULAR?

In the next attempt, I used a cloud texture and a noise texture to perturb the cloud's texture coordinates. Essentially one would sample the perturbing texture, multiply it by a scale value and add the current texture translation. The effect is much more interesting than two bitmap cloud textures.

However, why was a large dome of colored sky blocking off the cloud sheet? It may be risky, but I extended the far plane to get some pretty good cloudiness:

After this lovely sidetrack, I should be able to get back to profiling. It'll be a lot more convincing if I don't have my computer plugged in.
