Struct PositionStreamChannels 

pub struct PositionStreamChannels {
    pub position: Option<ChannelEncoding>,
    pub joints: bool,
}

The channels of the position vertex stream: a position and, for a skinned mesh, the joint indices and weights that deform it.

Joints and weights share this stream rather than getting one of their own, so a skinned mesh’s per-vertex data stays one buffer and one stride. The joint pair is addressed by vertex index rather than by attribute, so nothing else about a draw changes when the stream carries it.

The order is the attribute order: position, joint indices, joint weights.

Fields

position: Option<ChannelEncoding>

How the position itself is encoded, or None for a variant that reads no position at all — its geometry is a single point at the instance origin, which is what a point or impostor draw wants.

joints: bool

Whether the stream carries joint indices and weights.
