maxAnisotropy

Get Signature

get maxAnisotropy(): number

Defined in: src/gfx/graphics/webGpu/core/texture/Texture.ts:749

Maximum anisotropy clamp used by the sampler.

Returns

number

Set Signature

set maxAnisotropy(value): void

Defined in: src/gfx/graphics/webGpu/core/texture/Texture.ts:753

Specifies the maximum anisotropy value clamp used by the sampler. Anisotropic filtering is enabled when GPUSamplerDescriptor#maxAnisotropy is > 1 and the implementation supports it. Anisotropic filtering improves the image quality of textures sampled at oblique viewing angles. Higher GPUSamplerDescriptor#maxAnisotropy values indicate the maximum ratio of anisotropy supported when filtering.

Most implementations support GPUSamplerDescriptor#maxAnisotropy values in range between 1 and 16, inclusive. The used value of GPUSamplerDescriptor#maxAnisotropy will be clamped to the maximum value that the platform supports. The precise filtering behavior is implementation-dependent.

Parameters

value

void

Methods

_ensureBound()

_ensureBound(ctx?): Context3D

Defined in: src/gfx/graphics/webGpu/core/texture/Texture.ts:28

Ensure this texture is bound to a Context3D and return it. Resolution order: explicit arg, prior bindCtx(), then the single-engine default (same contract as Engine3D._defaultContext() for no-arg material constructors). Throws only when the choice is ambiguous — no engine yet, or several engines alive without an explicit ctx.
