SUMMARY

Delete applies TouchDesigner's Delete POP to packed points through its Attribute, Thin, Pattern, Group and Bounding pages, and Operation chooses whether the selection is deleted or kept. Afterward the instance ids are renumbered and the pieces of removed points are dropped, so every downstream operator stays in step with the stream.

Attribute, Pattern, Group and Bounding conditions are built from sequential blocks combined with and, or, xor, nand and nor; for example P(0) > 0 and P(1) < 0 deletes a quarter of the space. Bounding blocks test boxes and spheres placed by a transform, or the surface or outline of geometry on the second input. Plain POPs work as well.

PARAMETERS

PAGEDelete

[+]Operation	Invert	Inverts the selection of elements being deleted.
[+]Entity	Entity	Determines whether points or primitives are deleted.
[+]Line Strip Behavior	Linestripbehavior	Determines what happens to a line strip when some of its points are deleted.
Copy Topology Info Back to CPU	Cpureadback	Enable copying the point count and topology information held on the GPU to the CPU.

PAGEAttribute

Attribute	Attr	Start of Sequential Parameter Blocks for attribute conditions.
[+]Combine	Attr0combine	Specify how to combine the current attribute condition block with the one above.
[+]Attribute	Attr0inattr	Name of attribute for conditions.
[+]Function	Attr0func	Comparison function used to determine which elements are selected based on its attribute value.
Value	Attr0value	The value the attribute is compared against.
Invert	Attr0invert	Invert the selection resulting from the current conditions in the block.

PAGEThin

Enabled	Thinenabled	Enable thinning by index range, index step or random index.
Thin Out Range	Thinoutrange	Enable index-based point filtering.
Thin Range Start	Thinrangestart	Determines the starting index for range-based point filtering.
Thin Range Length	Thinrangelength	Determines the number of points being filtered by index range.
Thin Step	Thinstep	Filters every Nth point.
Thin Random	Thinrandom	Determines the proportion of points randomly filtered.
Thin Random Seed	Thinrandomseed	Sets the random seed for points being randomly filtered.
Invert	Thininvert	Invert the selection resulting from the current conditions in the block.

PAGEPattern

Pattern	Pattern	Start of Sequential Parameter Blocks for index-matching pattern.
[+]Combine	Pattern0combine	Specify how to combine the current pattern block with the one above.
Invert	Pattern0invert	Invert the selection resulting from the current conditions in the block.
[+]Pattern	Pattern0pattern	Index-matching pattern. See Pattern Expansion in wiki.

PAGEGroup

Group	Group	Start of Sequential Parameter Blocks for input groups.
[+]Combine	Group0combine	Specify how to combine the current group block with the one above.
Group	Group0name	The name of the group to use.
Invert	Group0invert	Invert the selection resulting from the current conditions in the block.

PAGEBounding

Display Bounds	Displaybound	Enable drawing the enabled bounding volumes. Surfaces and Outlines use the second-input geometry.
[+]Display Color	Displaycolor	Sets the color of the bounds guide.
[+]Ray Direction	Raydir	Constant direction to cast rays to determine if candidate point is inside or outside.
[+]Hardware Ray Tracing	Hwraytracing	Selects mode for Hardware Ray Tracing if supported. Used by the Volume scatter inside test, Windows only.
Bound	Bound	Start of Sequential Parameter Blocks for bounding volumes.
Enabled	Bound0enabled	Enable this bounding block.
[+]Combine	Bound0combine	Specify how to combine the current bounding volume block with the one above.
Attribute	Bound0inattr	Name of position attribute for bounding volume.
[+]Bounding Type	Bound0type	The type of bounding volume: a box or sphere placed by the transform below, or the surfaces or outlines of the second input.
[+]Translate	Bound0translate	These three fields translate the bound in the three axes.
[+]Rotate	Bound0rotate	The rotation of the bounding volume. Angles are given in degrees.
[+]Scale	Bound0scale	The scale of the bounding volume.
Invert	Bound0invert	Invert the selection resulting from the current conditions in the block.

PAGECommon

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.
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.
