# setDepthTestBounds(_:) Configures the range for depth bounds testing. ``` func setDepthTestBounds(_ bounds: ClosedRange) ``` ## Parameters `bounds` A closed range the renderer applies to depth bounds testing. The renderer discards fragments with a stored depth that is outside `bounds`. ## Discussion The render command encoder disables depth bounds testing by default. The render command encoder also disables depth bounds testing when the `bounds` property equals `0.0...1.0`. `bounds.lowerBound` needs to be greater than or equal to `0.0`. `bounds.upperBound` needs to be less than or equal to `1.0`. --- Copyright © 2026 Apple Inc.
