Colors about vector_math.dart HOT 9 CLOSED

Hi,

I think having an implementation in vector math makes sense.

from vector_math.dart.

Seperate Color class vs Vector4?

Top level methods for conversation to the different formats?

from vector_math.dart.

Separate color class with (static?) methods for converting between different formats.

from vector_math.dart.

Ok, I will look into this in the beginning of the next month.

Hi, any update on color class?

from vector_math.dart.

I stopped because I'm not sure if a seperate color class is usefull.Some users may want a rgb, some a argb color. But both classes would manly be copies of Vector3 oder Vector4. If they are seperate classes interacting with methods that take a Vector4 as an argument may be difficult. I think we should add the color related functions to the Vector4 (and 3?) class instead.
For the list of named colors I opened issue #46 to allow creating read only colors.

Hi,

I think the color support should be implemented as classes with static methods:

class ColorConversion {
static void FromRGBAToHSV(Vector4 v, Vector3 o);
}

from vector_math.dart.

Ping.

from vector_math.dart.

Ass a list what I would implement

• fromRGBA
• Parsing from hex color string with RGBA support
• To hex color string
• RGBA to HSV
• HSV to RGBA
• RGBA to HSL
• HSL to RGBA
• To grayscaled
• Gamma/Linear conversation?
  All methods have a input and a ouput Vector4 as parameter
• alphaBlend(Vector4 a, Vector4 b, Vector4 result)

Anything else? I will look into it later today or tomorrow.
