Raw data into a buffer

• writeBuffer()
• MAP_WRITE buffer + mapAsync() + copyBufferToBuffer()

Raw data from the network into a buffer

• fetch() + .arrayBuffer() + "Raw data into a buffer"

Raw (uncompressed or block-compressed) data into a texture

• writeTexture()
• "Raw data into a buffer" + copyBufferToTexture()

Raw (uncompressed or block-compressed) data from the network into a texture

• fetch() + .arrayBuffer() + "Raw data into a texture"

Image file into a texture

• TODO: paths through HTMLImageElement directly
• fetch() + .blob() + createImageBitmap() + copyExternalImageToTexture()
• HTMLImageElement + createImageBitmap() + copyExternalImageToTexture()
• HTMLImageElement + .decode() + createImageBitmap() + copyExternalImageToTexture()
• .drawImage() + copyExternalImageToTexture()
• fetch() + ImageDecoder to VideoFrame + copyExternalImageToTexture()

Note that all of these paths use an intermediate image object to represent the decoded image. This may incur extra copies, so the recommended path may change if a new API becomes available.

Video frame into a texture

• HTMLVideoElement + copyExternalImageToTexture()
• HTMLVideoElement + importExternalTexture()
• VideoFrame + copyExternalImageToTexture()
• VideoFrame + importExternalTexture()

Canvas (e.g. 2d canvas) into a texture

• copyExternalImageToTexture()

ImageData into a texture

• .data + writeTexture(), if the exact encoding (format, color space, premultiplication) matches
• manual conversion + writeTexture()
• createImageBitmap() + copyExternalImageToTexture()
• .putImageData() + copyExternalImageToTexture()
