Besides, entering Full Screen Exclusive mode may fail when calling SetFullscreenState() if the display is not connected to the adapter that used for rendering. Also, the HDR10 metadata only works in Full Screen Exclusive mode, or borderless windowed mode with HWND_TOPMOST Z order (I guess is the full screen optimization get enabled), using borderless window with HWND_TOP Z order won't work (but this mode is easier to alt-tab on single monitor set up.). Setting it to a small value will make image darker despite outputting a very bright 1000 nit image. The only data have effects on the image is "Max Mastering Luminance" which can affect the image brightness. But most of the data does not affect the image on my Samsung UA49MU7300JXKZ TV.
I have also played around with HDR10 metadata to see how it affects the image. So the path traced lighting values are fed into ACES HDR tone mapper, transformed into Rec709 color space, and then divided by 80 when using scRGB color space(scRGB requires value of 1 to represent 80 nit). Thinking in this way make me feel more comfortable. A linear combination of RGB values with the color primaries basis vectors can represent a color and intensity. The Red/Green/Blue color primaries of a gamut is 3 basis vectors in the XYZ color space. So, instead of thinking color inside the horseshoe-shaped diagram, it is easier for me to think about the color in 3D XYZ color space. It is because the chromaticity diagram skipped the luminance information. Using a HDR backbuffer will show less clipped colorĪlthough, it makes sense to represent a wide color using negative numbers using barycentric interpolation, I was confused how it to represent the intensity at the same time. Ī debug chromaticity diagram showing Rec2020 color gamut. Because color gamut is usually displayed as CIE xy chromaticity diagram, I used to think of a given RGB value as a color interpolated inside the Red/Green/Blue gamut triangle using the barycentric coordinates. I was confused about using negative values to represent a color (as well as intensity) at first. scRGB use the same color primaries at Rec709, which support wide color using negative values. But it is recommended to use scRGB color space on Windows. Rec2020 color space is the common HDR10 format with PQ EOTF. scRGB color space (DXGI_FORMAT_R16G16B16A16_FLOAT + DXGI_COLOR_SPACE_RGB_FULL_G10_NONE_P709) There are 2 swapchain formats/color spaces can be chosen to output HDR images on HDR capable monitor/TV:ġ.

The updated demo can be downloaded here.Ī photo of my HDR TV to show the difference between SDR and HDR path trace at 1080, and bilinear upscale to 4K.) and added dithering to tone mapped output to reduce color banding (Integer back buffer format only). It also has various small features updated such as adding per monitor high DPI support, path trace resolution scale (e.g. These values compensated for the fact that most projectors cannot output pure black - there's always some light 'leaking' out.Continue with the DXR Path Tracer in the last post, I updated the demo to support HDR display. The end result of gamma greater than 1.00 is to brighten the edge blend area, whereas gamma values less than 1.00 reduce it. These values define the horizontal and vertical gamma correction values, to try to compensate for a projectors gamma factor. These two values (horizontal and vertical) define the edge blend widths. The guide lines show the user where the edge of the image is, and where the edge blending starts and stops. guide lines are only present when the user is in the Adjust Independent mode with 1A set to 'R' edge blending, and 2B set to 'L' edge In most cases, for projector edge blending, the unit is used in Mode, you can have different edge blend settings for 1A, 1B, 2A and 2B When edge blending isĪctive, keying is not possible on that channel. This can be changed from to select any of the 4 edges for edgeīlending (and any of the 16 combinations of edges).
The edge blending additions to the unit's menu are in 'Adjust keyers': Note that edge blending on a window cannot be done at the same time as Note that this document is best viewed on a computer display as it uses Projector setup: Edge blending setup 1.6.pdf The following document has been prepared to help the user with such
