Vertex

Vertex consists of x, y, z and w whereas w is optional.
Example xyzw: v 0.1 1.2 2.3 3.4
Example xyz: v 0.1 1.2 2.3

Fields of Vertex

x: f64y: f64z: f64w: Option<f64>

VertexNormal

VertexNormal consists of x, yand z. The normal will usually but is not required to be a unit vector.
Example: vn 0.1 1.2 2.3

Fields of VertexNormal

x: f64y: f64z: f64

VertexTexture

VertexTexture consists of u, v and w whereas u and w are optional.
Example uvw: vt 0.1 1.2 2.3
Example uv: vt 0.1 1.2
Example u: vt 0.1

Fields of VertexTexture

u: f64v: Option<f64>w: Option<f64>

VertexParameter

VertexParameter consists of u, v and w whereas v and w are optional.
u is a 1D control point in the parameter space of a curve. u + v is a 2D control point in the parameter space of a surface.
Control poins for non rational trimming curves require u + v.
Control points for rational trimming curves require u + v + w.
w defaults to 1.0 if not set.
Example uvw: vp 0.1 1.2 2.3
Example uv: vp 0.1 1.2
Example u: vp 0.1

Fields of VertexParameter

u: f64v: Option<f64>w: Option<f64>

Point

The point entity contains a list of points in space.
Example (3 points): p 0 1 2
Example (1 point): p 0

Fields of Point

vertices: Vec<i64>

Line

Line consists of an arbitrary number (whereas n >= 2) of vertices that describe the path.

Fields of Line

vertices: Vec<i64>

Face

Face consists of an arbitrary number (whereas n >= 3) of complex vertices that describe the polygon.
Example (vertex): f 0 3 6
Example (vertex+normal+texture): f 0/1/2 3/4/5 6/7/8
Example (vertex+normal): f 0/1 3/4 6/7
Example (vertex+texture): f 0//2 3//5 6//8

Fields of Face

vertices: Vec<FaceVertex>
