createBuffer method

StorageBuffer createBuffer(
  1. BufferDescriptor descriptor, {
  2. ByteData? contents,
})
inherited

A buffer of BufferDescriptor.lengthInBytes bytes, for the usages it names, holding contents (zeros by default).

The general form of uploadGeometry: one allocation a compute pass writes, an indirect draw reads its counts from, and a draw binds as vertices (StorageBuffer.asVertices) or indices (StorageBuffer.asIndices). DeviceFeature.buffers; a BufferUsage.storage buffer needs compute or renderStageStorage, and a BufferUsage.indirect one indirectDraw or indirectDispatch. Released through releaseStorageBuffer.

The one way to make a storage buffer, since 1.0. createStorageBuffer was a second call for a subset of this one: what it made is BufferUsage.standardStorage with the bytes as contents, plus BufferUsage.hostReadable for hostReadable: true and BufferUsage.index for bindableAsIndices: true (H11: a compute pass writes a draw's order and the draw reads it, nothing crossing back).

Implementation

StorageBuffer createBuffer(
  BufferDescriptor descriptor, {
  ByteData? contents,
}) => throw refuse(DeviceFeature.buffers);
