Summary[edit]
The Facet POP does operations to make points ve shared between multiple primitives, or create new points so that the points are not shared.
Unique Points will create new points so that each vertex of each primitive does not shared a point with any other vertex. (exception: on closed line strips the first vertex and the last vertex refer to the same point, by definition)
Consolidate Points will potentially reduce the number of points by combining points that are within a specified distance tolerance into one point. Then multiple vertices may refer to each point, i.e. "share" a point.
Cusp Polygon will look at all edges between polygons, and if the adjacent two faces to an edge are not aligned within a specified angle tolerance, it will make the edge point unique.
You may follow the Facet POP with a Normal POP which computes the point or vertex normals, giving the surfaces a faceted loop or not.

Parameter Color Space
parmcolorspace - ⊞ - Controls how all color parameters on this node are interpreted. The color values as treated as being in the selected color space, and are converted to the Working Color Space before they are used as part of the node's operation. Note that this does not change the color space of the node itself, as that is always in the Working Color Space.
- sRGB
srgb- sRGB color space, with sRGB transfer function. Considered an SDR color space with respect to Reference White.
- sRGB - Linear
srgblinear- sRGB color space, with linear transfer function. Considered an SDR color space with respect to Reference White.
- Rec.601 (NTSC)
rec601ntsc- Rec.601 with NTSC primaries color space, with Rec.601 transfer function. Considered an SDR color space with respect to Reference White.
- Rec.709
rec709- Rec.709 color space, with Rec.709 (same as Rec.2020) transfer function. Considered an SDR color space with respect to Reference White.
- Rec.2020
rec2020- Rec.2020 color space, with Rec.2020 (same as Rec.709) transfer function. Considered an HDR color space with respect to Reference White.
- DCI-P3
dcip3- DCI-P3 color space, with D65 white point and 2.6 gamma transfer function. Considered an HDR color space with respect to Reference White.
- DCI-P3 (D60)
dcip3d60- DCI-P3 "D60 sim" color space, with D60 white point, and 2.6 gamma transfer function. Considered an HDR color space with respect to Reference White.
- Display-P3 (D65)
displayp3d65- Display-P3 color space, with D65 white point, and sRGB gamma transfer function. Considered an HDR color space with respect to Reference White.
- ACES2065-1
aces2065-1- ACES 2065-1 (also known as ACES AP0) color space, with a linear gamma transfer function. Considered an HDR color space with respect to Reference White.
- ACEScg
acescg- ACEScg (also known as ACES AP1) color space, with a linear gamma transfer function. Considered an HDR color space with respect to Reference White.
- Passthrough
passthrough- When selected, the color values will be used as-is in the operation, without any modification or attempt to convert them into the Working Color Space.
Parameter Reference White
parmreferencewhite - ⊞ - When converting a parameter color value to the Working Color Space, this controls how it should be treated with respect to Reference White. If the Working Color Space is the same Reference White, then no adjustment is done. If they are different, then the Reference White level (brightness) of this color will be adjusted to the range expected by the Working Color Space. For example if the project is set to have a SDR Reference White of 120 nits, and the HDR Reference White is 80 nits, then a color of (1, 1, 1), which is 120 nits in the SDR color space, will be converted to be (1.5, 1.5, 1.5), which is 120 nits still in the HDR Working Color Space.
- Default For Color Space
default- Will use either the SDR or the HDR Reference White, based on the color space selected.
- Standard (SDR)
sdr- Will treat the Parameter Color Space as SDR for it's reference white value.
- High (HDR)
hdr- Will treat the Parameter Color Space as HDR for it's reference white value.
