Only in Wrap4D
The node projects screen points onto a mesh surface through a camera. It can be used to project tracked markers from R3DS 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 Width
image width to perform projection. In case of tracking points in R3DS Track, it should be the same width that was used for tracking. In fact, the width and height are only used to compute the aspect ratio
- Camera Height
image height to perform projection
- 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
