In order to build you need third party libraries. Before you start please read this: [LearnWebGPU](https://eliemichel.github.io/LearnWebGPU/getting-started/hello-webgpu.html )
Usage example:
// init glfw
glfwInit();
// create a windowed mode window and its opengl context
glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
GLFWwindow* window = glfwCreateWindow(800, 800, "WebGPU base app", nullptr, nullptr);
// get window size
int width{}, height{};
glfwGetWindowSize(window, &width, &height);
// init engine webgpu
tvg::Initializer::init(tvg::CanvasEngine::Wg, 0);
// create wg canvas
auto canvasWg = tvg::WgCanvas::gen();
canvas_wg->target(glfwGetWin32Window(window), width, height);
//Test for Stroke Dash for Arc, Circle, Rect
auto shape = tvg::Shape::gen();
shape->appendArc(70, 600, 160, 10, 30, true);
shape->appendCircle(70, 700, 20, 60);
shape->appendRect(130, 710, 100, 40);
shape->strokeFill(255, 0, 0);
shape->strokeWidth(5);
shape->strokeJoin(tvg::StrokeJoin::Round);
shape->strokeCap(tvg::StrokeCap::Round);
if (canvas_wg->push(std::move(shape)) != tvg::Result::Success) return;
while (!glfwWindowShouldClose(window)) {
// webgpu
canvas_wg->draw();
canvas_wg->sync();
// pull events
glfwPollEvents();
}
// terminate engine and window
tvg::Initializer::term(tvg::CanvasEngine::Wg);
glfwDestroyWindow(window);
glfwTerminate();
