An example of RAII wrapper for WebGPU's wgpu::Buffer
// Using
#include <webgpu/webgpu.hpp>
namespace raii {
class Buffer {
// Whenever a RAII instance is created, we create an underlying resource
Buffer(wgpu::Device device, const wgpu::BufferDescriptor& bufferDesc)
: m_raw(device.createBuffer(bufferDesc))

Snippet for reproducing the Shift+D in a node graph editor in Blender
import bpy
def duplicate_node(n1, node_group=None, duplicate_links=False):
Duplicate a node (without duplicating its links)
@param n1 The node to duplicate
@param node_group (optional) Group in which the node must be duplicated
@param duplicate_links Whether to keep input links or not
@return the new duplicate node

* Create a new Mesh representing a simple pizza (really just a disc with
* a few quads on top of it).
* olive_count is the number of olives topping the pizza
* radius is the radius of the pizza
* base_polys is filled with the range of polygons belonging to the base
* olive_polys is filled with the range of polygons representing the olives
