Batch Rendering in LWJGL3 | Coding a 2D Game Engine in Java #11
Join the Discord: / discord
I apologize in advance for this lengthy tutorial, unfortunately there is no easy way to create a batched renderer in 20 mintues, so this one is a bit long :)
In this tutorial, I go over how to create a 2D batched renderer, that is able to render thousands of sprites at 60 FPS. This will increase framerates from 1 FPS, to 60 FPS. What I go over, is how to use the game objects transform to create a set of vertices for every single quad inside the batch renderer, and then upload that vertex buffer to the GPU every frame.
Then, I go over how to create a Renderer class that finds a RenderBatch that has room for a quad, or creates a new RenderBatch if there is none, and then adds the quad to that RenderBatch. The renderer will also sort the batches and render them to the screen.
