minLOD

The lowest mipmap level of detail for the texture.

Declaration

var minLOD: Float { get }

Discussion

The property represents the lower limit of the level-of-detail (LOD) range that texture operations access for the texture. When the GPU calculates a mipmap level, it applies the value of this property as the final step, after clamping the sampler LOD and applying the texture view level range offsets.

Each of the following texture operations has a requirement for the minLOD value.

Operation	Requirement
Read	`floor(minLOD)` ≤ mip level
Gather	`floor(minLOD)` ≤ `levelRange.location`
Sample	`minLOD` ≤ `levelRange.location` + `levelRange.length`

Each operation returns an out-of-bounds value if a parameter doesn’t meet a requirement.
