}

How the sampler should behave when it needs to access a pixel that is out of range of the texture.

Variants

Repeat

Repeat the texture. In other words, the pixel at coordinate x + 1.0 is the same as the one at coordinate x.

MirroredRepeat

Repeat the texture but mirror it at every repetition. In other words, the pixel at coordinate x + 1.0 is the same as the one at coordinate 1.0 - x.

ClampToEdge

The coordinates are clamped to the valid range. Coordinates below 0.0 have the same value as coordinate 0.0. Coordinates over 1.0 have the same value as coordinate 1.0.

ClampToBorder

Any pixel out of range is colored using the colour selected with the border_color on the SamplerBuilder.

When this mode is chosen, the numeric type of the image view’s format must match the border color. When using a floating-point border color, the sampler can only be used with floating-point or depth image views. When using an integer border color, the sampler can only be used with integer or stencil image views. In addition to this, you can’t use an opaque black border color with an image view that uses component swizzling.

MirrorClampToEdge

Similar to MirroredRepeat, except that coordinates are clamped to the range [-1.0, 1.0].

The sampler_mirror_clamp_to_edge feature or the khr_sampler_mirror_clamp_to_edge extension must be enabled on the device.
