Nutcracker: Bug fix, enhancements for Spiral Class, Part #1

[smeighan]

Well, i have done a major rewrite of the spirals effect class (More than 50% of code was rewritten).
The summary of changes
1) rotation (BUG), this was not working as i originally envisioned it. This now tells how many times a spiral rotates from the top of the tree to the bottom. Works now and you get a bonus, if you se this value to zero, you will have vertical bars
2) color palette (ENHANCEMENT). Spirals now have up to 6 colors in its palette
3) Rainbow Hue (ENHANCEMENT). If you answer Yes to this then your first two colors will be used to create a rainbow hue between the two (This is the way spirals has always worked)
If you answer N, then your color palette will be used. If you have 3 spirals, the first 3 colors from your palette are used. If you choose 8 spirals, the 6 colors from your palette are used for the first 6 and then the first two are reused.
4) Speed (ENHANCEMENT). Now you can speed up and slow down your spirals
5) Fade 3D (ENHANCEMENT). This follows the way the bar effect works. If You answer yes , each spiral will fade away in intensity. This gives a 3D effect to the spiral. If you answer no, you will get solid color spirals (This is the way spirals has worked in the past).


This effect now has the most prompts of any effect class.  The effect prompts we will talk about are highlighted below:

First lets look at the Rainbow Hue prompt

rainbow_hue = 'Y'. Here we use your color1(RED) and color2(BLUE) and shift through the Hue spectrum between the two


rainbow_hue='N' (This causes us to use your color palette)



Now lets look at the number of rotations. This was broken, but it works now
number rotations = 0.0. This will give you vertical bars


number rotations = 0.1


number rotations = 0.5


number rotations = 1.0


Next lets look at the new option for speed




speed = 0.1





speed = 0.5





speed =1.0





speed =2.0







too many images, so will post second half
