lovr.graphics.isHDR

Edit

Returns whether the super experimental HDR mode is active.

To enable HDR, add t.graphics.hdr to lovr.conf. When enabled, LÖVR will try to create an HDR10 window. If the GPU supports it, then this function will return true and the window texture will be HDR:

• Its format will be rgb10a2 instead of rgba8.
• The display will assume its colors are in the Rec.2020 color space, instead of sRGB.
• The display will assume its colors are encoded with the PQ transfer function, instead of sRGB.

For now, it's up to you to write PQ-encoded Rec.2020 color data from your shader when rendering to the window.

hdr = lovr.graphics.isHDR()

Notes

The following shader helper functions make it easier to convert between sRGB colors and HDR10:

vec3 pqToLinear(vec3 color);
vec3 linearToPQ(vec3 color);
vec3 sRGBToRec2020(vec3 color);
vec3 rec2020ToSRGB(vec3 color);
