Control (UI) Default Value Function
depthrelativeshadingrate 1 By default, shading rates are isotropic, and the shading
rate in depth is the same as the shading rate
perpendicular to the camera or incoming ray. The
shading rate in this case is set using the ShadingRate
attribute. If a depthrelativeshadingrate is specified, the
ShadingRate is independently multiplied by the
depthRelativeShading rate, with the product determining
the shading rate used in the volumetric.

depthinterpolation smooth Controls the interpolation of color on voxels in the plane
parallel to the camera. When set to smooth the result is
akin to performing a piecewise trapezoidal integration of
the volume elements along the depth of the volume.
When set to constant the result is a piecewise
rectangular integration.
deptherror 0.00392 Controls visible point list compression.
refinementstrategies None Sets the refinement strategy used in conjunction with
relativeshadingrate and depthrelativeshadingrate. The
goal of a refinement strategy is to increase the shading
rate in specific areas.
grouping
membership N/A Controls group membership of subsequent primitives. A
single primitive can be a member of many groups, and
membership is used to control trace relationships
between objects. Ray-tracing shaders on one object can
limit their ray intersections to members of specific groups
by using the optional subset parameter of the tracing
operators.
