Expand description

How drawing operations should modify the stencil buffer.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Keep

Drawing operations will not modify the stencil buffer.

§

Zero

Drawing operations will set the corresponding values in the stencil buffer to 0.

§

Replace

Drawing operations will replace the corresponding stencil values with the reference value.

§

Increment

Drawing operations will increment the corresponding stencil values by 1.

§

IncrementWrap

Drawing operations will increment the corresponding stencil values by 1. If a value of 255 is incremented, it will wrap back around to 0.

§

Decrement

Drawing operations will decrement the corresponding stencil values by 1.

§

DecrementWrap

Drawing operations will decrement the corresponding stencil values by 1. If a value of 0 is decremented, it will wrap back around to 255.

§

Invert

Drawing operations will bitwise invert the corresponding stencil values.
