BatchedInstanceBuffer

bevy::render::batching::no_gpu_preprocessing

Struct BatchedInstanceBuffer 

Source 
pub struct BatchedInstanceBuffer<BD>(pub GpuArrayBuffer<BD>)
where
    BD: GpuArrayBufferable + Sync + Send + 'static;
Expand description

The GPU buffers holding the data needed to render batches.

For example, in the 3D PBR pipeline this holds MeshUniforms, which are the BD type parameter in that mode.

Implementations§

Source§

impl<BD> BatchedInstanceBuffer<BD>
where BD: GpuArrayBufferable + Sync + Send + 'static,

Source

pub fn new(limits: &Limits) -> BatchedInstanceBuffer<BD>

Creates a new buffer.

Source

pub fn instance_data_binding(&self) -> Option<BindingResource<'_>>

Returns the binding of the buffer that contains the per-instance data.

If we’re in the GPU instance buffer building mode, this buffer needs to be filled in via a compute shader.
