Point POP
Summary
The Point POP is similar to the Primitive POP but it creates points only and has no inputs. It is suitable for creating single-point POPs that can act like Uniforms in a Math Mix POP or Math Combine POP when combining with other attributes. (Math Mix and Combine let you combine single-point POPs with multi-point POPs.)
It is useful for creating POPs with no P attribute, like for example, one Color attribute. it is useful for creating a simple point list for the Field POP and Force POP (one point per field or force).
Any attributes can be created on the Setup page, then you give each point values on the Points page.
For every point in the point list, it creates a Point Primitive in the primitive list (attach a POP to DAT to confirm, and select the class Primitive). You can create point only with no primitives by turning off Create Point Primitives.

Parameters - Common Page
Bypass
bypass - Pass through the first input to the output unchanged.
Free Extra GPU Memory
freeextragpumem - Free memory that has accumulated when output memory has grown and shrunk.
Delete Input Attributes
delinputattrs - Only output which attributes you specify in this POP - helps isolate attributes into a separate branch.
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.
- Use Parent Panel
useparent- Will use the Reference White that the parent panel has selected. If the top-level panel also has 'Use Parent' selected, then 'UI Reference White' will be used.
- 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.
- UI
ui- Will treat the Parameter Color Space as UI for it's reference white value. This uses the 'UI Reference White Nits' value for it's brightness.
