Overview

A solved camera track's 3D point cloud: each tracked feature drawn as a flat dot of constant pixel size, colored by the plate. Scene+ creates one; snap cards and geometry to it, or mesh it with CloudMesh3D.

How to

How-to

Scene+ from a solved CameraTracker creates one; each tracked feature is a marker in 3D.
Snap cards and geometry to the markers.

Inputs

in	the image this node works on

Outputs

Output	Type
out	Scene

Parameters

Parameter	Type	Default	What it does
tx	Float	0.0	Translate X — position along the world X axis, metres.
ty	Float	0.0	Translate Y — position along the world Y axis (up), metres.
tz	Float	0.0	Translate Z — position along the world Z axis, metres. The camera looks down −Z.
rx	Float	0.0	Rotate around X, degrees.
ry	Float	0.0	Rotate around Y (turntable), degrees.
rz	Float	0.0	Rotate around Z (roll), degrees.
sx	Float	1.0	Scale along X. 1 = unchanged.
sy	Float	1.0	Scale along Y.
sz	Float	1.0	Scale along Z.
points	Text		The points, as a text list of x y z triples (one point a line), or the file they are read from.
size	Float	4.0	The effect's size/radius in pixels.
color	Color	[0.35, 0.85, 0.9, 1.0]	The colour.
colors	Text		The points' colours, as a text list of r g b triples in the same order (empty = the display colour).
disabled	Bool	false	Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back.
label	Text		A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache.
hide_input	Bool	false	Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap).
