init(colorGradientFrom:to:name:textureDimensions:)
Initializes a texture that creates a vertical gradient between two colors.
Declaration
init(colorGradientFrom color1: CGColor, to color2: CGColor, name: String?, textureDimensions: vector_int2)Parameters
- color1:
The color at the top of the gradient.
- color2:
The color at the bottom of the gradient.
- name:
The Name property for the new texture object.
- textureDimensions:
The texel dimensions (width and height) of the texture image.
Return Value
A new color swatch texture object.
Discussion
Model I/O interpolates between the color1 and color2 colors by hue, saturation, and lightness to create a color gradient when generating texture data.
This initializer does not generate texel data; the MDLColorSwatchTexture class automatically generates data and caches it for reuse when you use one of the MDLTexture methods listed in Accessing Texture Data.
