Property Detail
|
readnonatomicassign |
Number of vertices in the Augmented Faces mesh.
The vertexCount will not change. Currently, there are 468 vertices, although this might change in the future.
|
readnonatomicassign |
A float buffer of 3D vertex locations in (x, y, z) packing.
These vertices are relative to the center transform of the face. Units are in meters.
|
readnonatomicassign |
A float buffer of UV texture coordinates in (u, v) packing.
There is a pair of texture coordinates for each vertex. The textureCoordinates will not change.
|
readnonatomicassign |
A buffer of 3D normals in (x, y, z) packing.
Each (x, y, z) is a unit vector of the normal to the surface at each vertex. There is exactly one normal vector for each vertex. These normals are relative to center transform of the face.
|
readnonatomicassign |
Number of triangles in the face mesh.
This is equivalent to the number of elements in triangleIndices divided by 3. The count will not change.
|
readnonatomicassign |
A buffer of triangles' indices in consecutive (i0, i1, i2) triplets.
Every three consecutive values are indices that represent a triangle. The front face of each triangle is defined by the face where the vertices are in counter clockwise winding order.
The triangleIndices will not change.
