Hermet Park	090ebfba86	xrenderer/engines: support the canvas viewport function. ... The viewport function defines the rectangular area of the canvas that will be used for drawing operations. It is used to clip the rendering output to the boundaries of the rectangle. Apps can use this function to set the drawing region within the canvas. When the ThorVG canvas is partially inside the screen area such as during scrolling it could help enhance rendering performance. New Experimental API: - Result Canvas::viewport(int32_t x, int32_t y, int32_t w, int32_t h) noexcept; Issue: https://github.com/thorvg/thorvg/issues/2274	2024-06-24 14:20:46 +09:00

Sergii Liebodkin	938b69688d	wg_engine: Added ability to draw multiple solid color filled shapes ... [issues 1479: Shape](https://github.com/thorvg/thorvg/issues/1479) 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); // prepare a shape (Rectangle + Rectangle + Circle + Circle) auto shape1 = tvg::Shape::gen(); shape1->appendRect(0, 0, 200, 200); //x, y, w, h shape1->appendRect(100, 100, 300, 300, 100, 100); //x, y, w, h, rx, ry shape1->appendCircle(400, 400, 100, 100); //cx, cy, radiusW, radiusH shape1->appendCircle(400, 500, 170, 100); //cx, cy, radiusW, radiusH shape1->fill(255, 255, 0); //r, g, b canvas_wg->push(std::move(shape1)); 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();	2023-12-26 17:51:17 +09:00
SergeyLebedkin	35b03c826e	wg_engine: introduce a webgpu canvas(engine) ... WebGPU is a Render Hardware Interface built on top of the various APIs provided by the driver/OS depending on your platform. WebGPU exposes an API for performing operations, such as rendering and computation, on a Graphics Processing Unit. WebGPU official documentation: https://www.w3.org/TR/webgpu/ The new engine type introduced: tvg::CanvasEngine::Wg The new canvas type introduced: tvg::WgCanvas Example: $meson setup build -Dengines=wg_beta ` // 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); // ... // terminate engine and window tvg::Initializer::term(tvg::CanvasEngine::Wg); ` Still this feature is under the beta Issue: https://github.com/thorvg/thorvg/issues/1479	2023-12-26 17:49:16 +09:00
