    Class KTX2TextureLoader

    A texture loader for KTX2 format files that handles transcoding of compressed texture data.

    KTX2 is a container format for GPU textures that supports various compression formats including Basis Universal (ETC1S and UASTC). This loader can transcode KTX2 textures to device-specific formats based on available GPU extensions.

    The loader supports:

    • ETC1S and UASTC4x4 compressed formats
    • Multiple target formats (ASTC, BC, ETC, PVRTC, etc.)
    • ZSTD supercompression
    • Mipmap generation
    • Both WebGL and WebGPU rendering contexts
    const loader = KTX2TextureLoader.getInstance();
    const textureData = await loader.transcode(ktx2ArrayBuffer);

    Methods

    • Transcodes a KTX2 texture from the provided byte array.

      This method parses the KTX2 container, validates its format constraints, and transcodes the texture data to a format suitable for the current GPU.

      Parameters

      • engine: Engine
      • uint8Array: Uint8Array

        The KTX2 texture data as a Uint8Array

      Returns Promise<
          {
              compressionTextureType: CompressionTextureTypeEnum;
              height: number;
              mipmapData: TextureData[];
              needGammaCorrection: boolean;
              width: number;
          },
      >

      A promise that resolves to the transcoded texture data

      Error if the texture format is not supported (3D textures, array textures, or cube textures)

      const ktx2Data = new Uint8Array(buffer);
      const textureData = await loader.transcode(ktx2Data);
