Snowflakes has never worked they way i imagined it when i wrote it 6 months ago.

so, i rewrote it to get it closer to what i wanted and to fix some errors it was having.

Bug fix: no longer causes errors when generating effect

Enhancement:

1) Faster to generate

2) he number of frames of animation is equal to (sequence duration)/fame_timing

so if you have 50ms frame timng and a 11 sec duration sequence you will have 220 frames of animation.

3) 7 New prompts

color1 (was start_color)

color2 (was end_color)

speed (i think values around ..3 to .8 are prob better)

background_color (if and rgb value is ever zero, substitute with this value)

snowflake_type (0-6. discussed below)

colour_model (1,2. discussed below)

number_snowflakes (How many snowflakes are originally drawn).

So , let's discuss these.

First i changed the start_color, end_color to now be called color1, color2,. These colors are used differently than before.

There are two color models:

color_model #1:

color1 is the center dot of your snowflake. color2 is the color that wraps around the center.

here is an example

color model #2:

we start with color1 and then end with color2. if you have 10 snowflakes, the 1st snowflake will be color1, the 10th snowflake color2. the other 8 will be spread across the hue spectrum between the two colors.

here is an example using everything the same as above, but selecting color_model = 2:

A~SNOWFLAKE_DEMO2.gif

There are 6 types of snowflakes, this is set with snowflake_type:

type 1: a single pixel. this probably can look just like light snow

type 2: a single pixel surrounded by 4 additional pixels.

type 3: a 3 pixel vertical or 3 pixel horizontal snowflake. they are randomly picle vert or horiz.

type 4: a single pixel surrounded by 8 additional pixels.

type 5: a single pixel surrounded by 20 additional pixels.

type 6: a single pixel surrounded by 44 additional pixels.

types 2,4,5,6 create large and larger snowflakes, you need a big enough target model for the larger numbers.

Type 0: is a special case that will randomly select all of the above.

So here is an example of snowflake_type 5

New option background color, now works as expected. It will set your background color whenever it finds an rgb value of zero.
