The error screen uses an orthographic projection when rendered in a
window, so the text is always the same size instead of scaling with the
window size.
Also you can close it with escape.
Pass stores draw commands rather than sending them to Vulkan
immediately.
The main motivation is to allow more flexibility in the Lua API. Passes
are now regular objects, aren't invalidated whenever submit is called,
and can cache their draws across multiple frames. Draws can also be
internally culled, sorted, and batched.
Some API methods (tallies) are missing, and there are still some bugs to
fix, notably with background color.
- Add Buffer:newReadback
- Add Buffer:getData
- Buffer:getPointer works with permanent buffers
- Buffer:setData works with permanent buffers
- Buffer:clear works with permanent buffers
- Add Texture:newReadback
- Add Texture:getPixels
- Add Texture:setPixels
- Add Texture:clear
- Add Texture:generateMipmaps
- Buffer readbacks can now return tables in addition to Blobs using Readback:getData
Tally is coming back soon with an improved API, it's temporarily removed
since it made the transfer rework a bit easier.
Note that synchronous readbacks (Buffer:getData, Texture:getPixels)
internally call lovr.graphics.submit, so they invalidate existing Pass
objects. This will be improved soon.
It doesn't work as intended (due to glslang issues?). The current way
to write a shader that uses multiple attachments is to declare multiple
output variables, which is a little better because you can name them
however you want and customize the type.
It would be nice to be able to support a "void" entrypoint for multiple
attachments so you don't need to awkwardly return the first target's
color, but I can't find a way around this right now.
Also made a nifty helper function to move resources to the build folder,
in an effort to avoid writing duplicate versions of these functions for
each platform.
Although the name is unfortunate, this allows access to lovr.headset
when no window is opened or when the graphics module is disabled. This
requires the XR_MND_headless extension to be supported by the runtime.
There used to be oculus and pico but pico doesn't work anymore.
Eventually things will converge on the standard loader and we won't
need different loaders, but manifests may require flavors.
