Only in Wrap4D
The node projects screen points onto a mesh surface through a camera. It can be used to project tracked markers from Track back into 3D space to be used in wrapping.
Since ScreenPoints store points in a normalized (-1 to 1) format, the node requires to specify a resolution to perform projection. In fact, the node only needs uses the resolution to compute the aspect ratio.
ProjectScreenPoints node has a visual editor with two viewports. The left viewport displays the result of the projection of the screen points onto the mesh. The right viewport displays the same result through the camera view.

- Use Camera Resolution:
is set, the camera resolution will be
- Camera Resolution:
image width and height to perform projection. In case of tracking points in Track, it should be the same resolution that was used for tracking. In fact, the width and height are only used to compute the aspect ratio
- Show Point labels:
if set, points names will be visible in the editor
- Fail On Mistrace:
if set, the node returns an error if any of the points can’t be projected onto the mesh
