MapRenderingManager.readDepth() method​

Read depth at a specific point synchronously.

Performance considerations: - This is synchronous and will cause a GPU sync point, which may impact performance - For high-frequency use cases, prefer getDepthTexture() and shader-based solutions

Signature:

readDepth(ndc: THREE.Vector2 | THREE.Vector3): number | null;

Parameters​

Parameter

Type

Description

ndc

THREE.Vector2 | THREE.Vector3

Normalized device coordinates (x, y in range [-1, 1])

Returns:



number \| null

Depth value (in range \[0, 1\]) or null if reading failed
