The ProjectGeom node projects a source geometry onto a target geometry. For each vertex of source geometry it traces two rays (along and opposite to vertex normal) then it moves the vertex to the nearest intersection point.
One of common scenarios is to wrap a lowpoly basemesh around a scan then subdivide it and project resulting model to scan. That is how you can achive great level of details and not spend too much time on wrapping a heavy model.
- Source Geometry
GeometryA geometry to be projected
- Target Geometry
GeometryA geometry to which the source geometry will be projected
- Excluded Vertex Mask
VertexMaskVertex mask defining the areas that should not be projected
- Check Normals
if set, only projects to target polygons which normals look toward tracing ray
- Limit Distance
limits maximal distance of ray-tracing. The distance is specified in Distance parameter
maximal distance of ray-tracing if Limit Distance is checked
