Struct bevy::render::render_resource::DynamicStorageBuffer
[−]pub struct DynamicStorageBuffer<T> where
T: ShaderType, { /* private fields */ }
Expand description
Stores data to be transferred to the GPU and made accessible to shaders as a dynamic storage buffer.
Dynamic storage buffers can be made available to shaders in some combination of read/write mode, and can store large amounts
of data. Note however that WebGL2 does not support storage buffers, so consider alternative options in this case. Dynamic
storage buffers support multiple separate bindings at dynamic byte offsets and so have a
push
method.
The contained data is stored in system RAM. write_buffer
queues copying of the data from system RAM to VRAM. The data within a storage buffer binding must conform to
std430 alignment/padding requirements. DynamicStorageBuffer
takes care of serialising the inner type to conform to
these requirements. Each item push
ed into this structure
will additionally be aligned to meet dynamic offset alignment requirements.
Other options for storing GPU-accessible data are:
