In this directory you can find some examples of how to use the paradigm rendering library. The list in this readme will give you a pseudo-increasing difficulty of the examples, meaning earlier list entries should be easier to understand than later ones. They can often also be built upon concepts from earlier examples.

This is the simplest example, showing how to create a window and render a single screen. It is a good starting point for understanding the basic concepts of initializing the library and rendering a screen. It can also serve as a good smoke test to make sure your environment is set up correctly. If all goes well, you should see a screen with a single color (magenta) when running this example.

In this example, we render a single triangle to the screen. We handwave the library's initialization and focus entirely on the triangle being rendered. If you skip the HelloScreen example, you might be missing some context on how the library is initialized.

The end result of running this example should be a single triangle, where each point is a different color (red, green, and blue).

Showcases how to load the most minimal set of resources you need to render a textured triangle. It loads a material file, and a geometry file, which references shaders, textures, and a sampler.

Small sample showing how to instantiate a specific renderable multiple times with different instance data (such as position, rotation, scale, color, etc). It should spawn around 300'000 icospheres, each with a different color and position, and move them around every frame until they despawn in around 14-34 seconds after the start.

A little while off another group of 100 icospheres are continiously spawned every frame with a lifetime of 2 seconds.

Some general tips for instancing: Prefer doing bulk updates of instance data rather than setting each instance individually. You can inspect the core::ecs::systems::render how more complex instance updates are done (that is where the model matrix is updated every frame).
