SUMMARY

Geometry is the POPX Geometry COMP: it renders the pieces of a POPX chain, or any plain POP, and passes the stream through unchanged. One block per instance slot, kept in sync with the chain, assigns that slot's material and its Aura flags for rendering, camera visibility, shadows and reflections, and a Material operator can be set for the whole geometry.

Texture maps come from the POPX Material: the one set in Material, or the POPX Material upstream. In the Aura Render Engine, points render as spheres sized by Point Radius, lines as tubes sized by Line Width, and POPX fields as an iso surface or a volume.

PARAMETERS

PAGEGeometry

Material	Material	The material of the geometry: a POPX Material for Aura or a TouchDesigner MAT for the regular render. In POPX mode each instance slot uses its own Material on the POPX Instances page instead.
Render in Aura	Renderinaura	Enable rendering in Aura.
Visible to Camera	Visibletocamera	Enable visibility to the camera in Aura.
Cast Shadows	Castshadows	Enable shadow casting in Aura.
Visible to Reflections	Visiblerefl	Enable visibility in reflections in Aura.
Point Radius	Pointradius	Sets the radius of point primitives rendered as spheres. Multiplied by a PointScale point attribute when present.
Line Width	Linewidth	Sets the width of lines and line strips rendered as tubes. Multiplied by a LineWidth point attribute when present.
[+]Render As	Fieldrender	Determines how a field is rendered: as the surface where the Field Attribute crosses the Iso Value, or as a volume.
[+]Surface Type	Fieldsource	Determines how the Field Attribute is read for the surface: as a signed distance, or as a density the surface wraps.
Field Attribute	Fieldattr	Sets the field attribute that is rendered. Until one is picked, Dist is used for a Distance surface and Weight otherwise.
Iso Value	Isovalue	Sets the value of the Field Attribute where the surface lies. For a distance, 0 is the shape itself and higher values grow it.
Use Sparse	Fieldsparse	Renders the sparse grid of the source POPX Flow instead of its Output Field, at the simulation's own voxel size.
POPX Instances	Instances	Start of Sequential Parameter Blocks for instance materials. Automatically detects the number of instances from the input geometry.
Material	Instances0material	This instance slot's material: a POPX Material for Aura or a TouchDesigner MAT for the regular render.
Render in Aura	Instances0renderinaura	Enable rendering in Aura for this instance block.
Visible to Camera	Instances0visibletocamera	Enable visibility to the camera in Aura for this instance block.
Cast Shadows	Instances0castshadows	Enable shadow casting in Aura for this instance block.
Visible to Reflections	Instances0visiblerefl	Enable visibility in reflections in Aura for this instance block.

PAGECommon

Free Extra GPU Memory	Freeextragpumem	Free memory that has accumulated when output memory has grown and shrunk.
Render Primitives	Renderprimitives	Whether to render the full POPX geometry. When off, only point instances are drawn.
Convert to Point Primitives	Converttoptprim	Enable converting points to point primitives when Render Primitives is off.
SRT / RST	Srtrst	Sets the transform order, SRT or RST, used when the points are rendered as TouchDesigner instances.
