VISU Quickstart

This is a quickstart guide to create a minimal and lightweight VISU application for rapid prototyping.

Using this quickstart will provide you with the bare minimum code and scaffolding for a simple VISU application. If you're looking for the full scaffolding for more complex applications where you maintain full control, check out VISU Starter.

The Quickstart will provide the following:

• A minimal application class src/Application.php.
  • draw method with a simple rendering pipeline prebuilt.
  • update method which is called at a fixed interval.
• Simple game loop metrics, showing the current FPS, frame times, and update times.
• Event handling and Input Events.
  • An InputContext with no actions assigned.
• Offscreen rendering to a texture by default.
• Properly resizing render target and HDPI handling.
• ECS (Entity Component System) is available.
• Vector Graphics frame is preinitialized.

Prerequisites

• PHP 8.1 or higher
• PHP-GLFW extension installed
• Composer

Usage

Use Composer to create a new project based on visu-quickstart:

composer create-project phpgl/visu-quickstart -s dev --prefer-dist my-visu-project 

After the installation is complete, you can start the application by running:

cd my-visu-project
php ./bin/start.php
