Description
Table structure representing a mesh vertex used by various functions, such as IMesh:BuildFromTriangles and Entity:PhysicsFromMesh and returned by functions such as util.GetModelMeshes and PhysObj:GetMesh.
Parameters
normal [Vector]
The triangles normal required to calculate lighting(optional).
tangent [Vector]
The triangles tangent. Not used by the VertexLitGeneric shader.
binormal [Vector]
The triangles binormal. Not used by the VertexLitGeneric shader.
pos [Vector]
The vertex position.
u [number]
The u texture scale.
v [number]
The v texture scale.
userdata [table]
