Enum web_glitz::image::sampler::Wrap

pub enum Wrap {
    ClampToEdge,
    Repeat,
    MirroredRepeat,
}

Enumerates the methods available to a Sampler for texture coordinate wrapping.

Texture coordinate wrapping concerns texture coordinate values outside of the range 0.0..=1.0. The extremes of this range correspond to the edges of the texture. A texture coordinate value outside of this range therefore has to be mapped to a coordinate value on this range.

Separate wrapping methods can be used for each texture space coordinate component (typically referred to as the S, T, R coordinates or "width", "height", "depth" respectively), see SamplerDescriptor and ShadowSamplerDescriptor.

Variants

ClampToEdge

If the coordinate value is smaller than 0.0, then 0.0 is used as the coordinate value; if the coordinate value is greater than 1.0, then 1.0 is used as the coordinate value.

For example, -3.15 maps to 0.0 and 2.85 maps to 1.0.

Repeat

The integer part of the coordinate value is ignored.

For example, 3.15 maps to 0.15.

MirroredRepeat

Similar to [Repeat], however, if the integer part is odd, then the decimal part is subtracted from 1.

For example, 2.15 maps to 0.15 and 3.15 maps to 0.85.
