Protected gl

gl: WebGL2RenderingContext

Protected ready

ready: Promise<void>

Protected format

format: CompressedTextureStorageFormat | TextureFormat

How supplied texture data is interpreted.

For non-compressed textures, this means included channels and channel formats. See TextureFormat.

For compressed textures, this is the actual storage format. See CompressedTextureStorageFormat

Protected isCompressed

isCompressed: boolean = false

Protected isPreallocated

isPreallocated: boolean = true

Protected minLod

minLod: number

Protected maxLod

maxLod: number

Readonly width

width: number

Texture width in pixels.

Readonly height

height: number

Texture height in pixels.

Methods

Protected uploadLevelSync

  • uploadLevelSync(target: TextureCubeFace | TextureBindingPoint, level: number, width: number, height: number, type: BufferDataType | TextureDataType, srcData: ArrayBufferView): void

generateMipmaps

getTexture

getTextureSync

bindSync

  • bindSync(): boolean

  • If ready, binds the texture to the relevant binding point.

    Returns boolean

    true if the texture has been successfully bound, false otherwise.

delete

uploadPixels

  • Uploads an array of pixels to the GPU.

    example

    Uploading a 2x2px red/black checkerboard texture and a 1x1px dark red mipmap.

    import { Texture, BufferDataType } from '@gdgt/webgl';


    const myTexture = new Texture( {
        width: 2,
        height: 2,
        levels: 2,
    } );

    await myTexture.uploadPixels(
        {
            0: new Uint8Array([
                255, 0, 0, 255, 0, 0, 0, 255, 0, 0, 0, 255, 255, 0, 0, 255,
            ]),
            1: new Uint8Array([128, 0, 0, 255]),
        },
        BufferDataType.unsignedByte,
    );

    Parameters

    Returns Promise<void>
