Struct InstanceBuffer 

pub struct InstanceBuffer { /* private fields */ }

GPU buffer for storing instance data.

Implementations

impl InstanceBuffer

pub fn new( ctx: &WgpuContext, instances: &[InstanceData], label: Option<&str>, ) -> Self

Create a new instance buffer from a slice of instance data.

pub fn with_capacity( ctx: &WgpuContext, capacity: u32, label: Option<&str>, ) -> Self

Create an empty instance buffer with the given capacity.

pub fn update( &mut self, ctx: &WgpuContext, instances: &[InstanceData], ) -> Result<(), String>

Update the instance buffer with new data. If the new data is larger than capacity, returns an error.

pub fn buffer(&self) -> &Buffer

Get the raw wgpu buffer.

pub fn count(&self) -> u32

Get the number of instances.

pub fn capacity(&self) -> u32

Get the buffer capacity.

pub fn slice(&self) -> BufferSlice<'_>

Create a buffer slice for the entire buffer.
