CloudMesh3D

3Dv1app

Overview

Meshes a solved point cloud into a proxy: triangulates through the solve camera's view (Nuke's PointCloudGenerator meshing), keeps the cloud's plate colors as vertex color. One click after a solve gives a ground/set mesh for shadows, projections and layout.

How to

How-to

After a camera solve, wire the solved point cloud into cloud and name the solve camera in camera.
The cloud is triangulated through the camera's view, keeping the plate colours as vertex colour.
max_edge and depth_ratio stop triangles bridging gaps between surfaces; use the mesh for shadows, projections and layout.

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.
cloud	Text		The PointCloud3D node to mesh. Empty = the first tracker cloud in the scene.
camera	Text		The Camera3D to triangulate through - use the solve camera. Empty = the scene's default camera.
max_edge	Float	0.2	Longest triangle edge kept, as a fraction of the image width seen through the camera. Bigger fills larger gaps; 0 turns the filter off.
depth_ratio	Float	1.6	Triangles spanning more than this near-to-far depth ratio are dropped - they bridge a real depth break (a set edge against the sky). 1 or less turns the filter off.
display	Choice	inherit	How the viewport draws this mesh: `inherit` the scene's mode, or shaded, wireframe, points, bounds. `inheritshadedwireframeshaded_wirepointsbboxhidden`
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).
