Title: Color Function and Apply Color
Post by: rcallicotte on July 26, 2007, 01:13:04 PM
Does Color Function (when used) override Apply Color?  If not, what is the result of using both in tandem?

Other question is similar to the above two - Does the control for Apply Color affect the Color Function and, if so, how?

Y'know I've been wondering the exact same thing for a while now. To my knowledge it seems to do a 50/50 split of the two boxes.

Cool.  Thanks for the answer.  I hope it's okay if we get an official answer from Planetside, since I believe the same as you do, ProjectX.  The only problem is I can't see that it does anything.

If you have a black and white fractal as an input for colour function, it shades that colour from dark to light.
If you use a coloured fractal, its colour is mixed with the applied colour.

Thanks Volker.  Is the mixture between applied color and color function based upon the slide?

The slider is just changing the applied colour. I could be wrong, but this is what I presume ,-)

In fact, else I do not have a clue about that slide. At first I thought that at would only change brightness, but saturation is influenced, too.

The colour is multiplied by the colour function. For example, if your colour is white, the result is simply the colour function itself. If the colour is a grey, the result will be a darker version of the colour function. If you use something more colourful, that colour will tint the colour function.

Matt, does this then mean that white is represented as all 1s so therefore the color is multiplied by these 1s and stays the same?

That's correct.
