Add HDR Support for a richer color experience!

This is a very low priority since most people are not playing on HDR monitors with 10-bit color everywhere, but Minecraft has poor HDR support, and I have no in-game option to allow for 10-bit color since 8-bit color requires only 24 bits.

The option is easily enabled by setting the third parameter of

glTexImage2D

,

internalFormat

to either

GL_RGB32F

or

GL_RGBA32F

to create a 32-bit framebuffer, and it could be a configurable option that only requires creating a new framebuffer to use. It would require allowing support for HDR resourcepacks as well, such as using .hdr format, and properly implementing HDR texture atlas support which can also allow SDR texture mixing by using a texture atlas LUT which contains the image offset, and a single bit for whether the texture is SDR or HDR.

Without proper HDR support, the game is visually identical to using old 6-bit color graphics (with dithering artifacts) on an 8-bit SDR monitor, and you end up seeing grey instead of black, dark whites, and various color artifacts. This applies to fullscreen and windowed mode.

    As HDR monitors become more and more common place, it will be extremely important for Minecraft to natively support HDR. The ability to disable color clamping during the rendering process would open up a world of visual improvements. Things like sunlight being significantly brighter than torch light. Night vision being able to make all light brighter, and not just making dark the same as normal light. HDR textures so that lamp blocks can have significantly brighter pixels. All this can be done by just changing various internal formats.

    Please Mojang, we need this!

    The moving color gradients that are visible during sunrise and sunset would be much smoother with HDR (I think...).

    In Windows 10 Insider Preview Build 21337+, Auto HDR was brought over from Xbox, and works in Minecraft

    HDR support in minecraft would be INCREDIBLE

    I mean, win 10 edition already supports ray tracing (Java does too if you use optifine + shaders, but integrated support would be such a power move), so if we also add HDR support, then experience of minecraft would be hundreds of times better. I also wonder, if an HDR support update was a thing, then would it be accompanied with some really colorful features, like peafowls, opal stones, revamped parrots, chameleons, etc.?

    In my opinion, even standalone HDR update is going to be one of the best updates!

    I get the impression 'autohdr' is going to be the 'microsoft answer' to this one, sadly.

    You say it's easy to set the third parameter of

    glTexImage2D

    It's a shame there isn't a mod to showcase this as an example.

    HDR displays are becoming increasingly common and more and more people have to deal with a version of Minecraft that looks much more dull than other apps and causes the entire display to dim after closing whenever you play in fullscreen, requiring you to disable and re-enable HDR.

    How is this still not a thing? Almost every big game now supports HDR. This is basic stuff.
