[1.15.1] Where can I learn how to apply OpenGL for Minecraft?


Recommended Posts

Minecrafts got like everything abstracted away in multiple ways. Looking at vanilla’s code is the best way to understand stuff.


The basics of rendering are

- get the render buffer you want

- add data to that buffer


Your data then gets drawn by minecraft AT A LATER DATE. So you cannot interact with open GL directly as by the time your data is rendered, the open GL state will have been changed by other stuff.


You render data to a render type buffer by adding vertices to the buffer. You do this by calling methods on the buffer like “pos”, “color”, “tex” and then finish it off for each vertex with “endVertex()”. These methods are chainable so you can do “buffer.pos(x, y, z).color(r, g, b, a).tex(u, v).endVertex();”
