Render to texture -- where to start?

[AberrantWolf]

I've been looking for a place to inject code that would render a view of the scene to a texture that could be used later (like for security cameras). I see all sorts of places where I could inject rendering calls to the GL backend in order to draw more things or custom models into the scene, but I can't manage to find out where I could set an offscreen render target and render the whole scene from to that target before the player's view gets rendered. (After would also be okay...) Essentially I would need another culling and rendering pass for each custom view.

I'm totally fine for now with the limitation that I would only be able to render from the chunks currently loaded, of course.

 

I would prefer to no have to modify the core source of Minecraft or Forge. I imagine that this functionality would have been exposed by Forge already given that Vivecraft and the Replay Mod would likely be doing something similar. I just can't find the point where I would setup the scene, projection, render target, and then begin the culling/rendering cycle multiple times.

 

Cheers.

The api to handle the rendering is already built, it's amazing, it works across dimensions...you aren't going to get any better than that.

Oof, 1.7, though... Anyway, I'll dig in more in a bit. Thanks!

Thought XCW'd updated that recently. Maybe not.
