Enum RenderOp 

pub enum RenderOp {
    EnterClip {
        instance_index: u32,
        parent_ref: u8,
        new_ref: u8,
    },
    DrawBatch(DrawBatch),
    ExitClip {
        instance_index: u32,
        ref_value: u8,
    },
}

One entry in a per-phase DFS render stream.

The overlay stream is a sequence of these ops that the renderer executes in order, binding different pipelines for stencil writes vs. clipped color draws.

Variants

EnterClip

Write stencil INCR for a clip region entry. Render instance_index’s mesh with pipeline_stencil_incr, stencil reference = parent_ref. After this op, pixels under the mesh have stencil value new_ref.

Fields

instance_index: u32

parent_ref: u8

new_ref: u8

DrawBatch(DrawBatch)

Draw a batch of instances. batch.stencil_ref == 0 → use normal overlay pipeline. batch.stencil_ref > 0 → use clipped overlay pipeline with that reference. Instance indices live in [batch.start .. batch.start + batch.count) of the stream’s instance array.

ExitClip

Write stencil DECR to close a clip region. Render instance_index’s mesh with pipeline_stencil_decr, stencil reference = ref_value.

Fields

instance_index: u32

ref_value: u8
