format of the Rust library load locad blender obj file to Rust NDArray.
cargo run test\t10k-images.idx3-ubyte
A png file will be generated for the first image in the file.
Object files define the geometry and other properties for objects in Wavefront's Advanced Visualizer. Object files can also be used to transfer geometric data back and forth between the Advanced Visualizer and other applications.
The following types of data may be included in an .obj file. In this list, the keyword (in parentheses) follows the data type.
Vertex data
- geometric vertices (
v) - texture vertices (
vt) - vertex normals (
vn) - parameter space vertices (
vp)
Free-form curve/surface attributes
- rational or non-rational forms of curve or surface type: basis matrix, Bezier, B-spline, Cardinal, Taylor (cstype)
- degree (
deg) - basis matrix (
bmat) - step size (
step)
- point (
p) - line (
l) - face (
f) - curve (
curv) - 2D curve (
curv2) - surface (

Free-form curve/surface body statements
- parameter values (
parm) - outer trimming loop (
trim) - inner trimming loop (
hole) - special curve (
scrv) - special point (
sp) - end statement (
end)
- connect (
con)
- group name (
g) - smoothing group (
s) - merging group (
mg) - object name (
o)
- bevel interpolation (
bevel) - color interpolation (
c_interp) - dissolve interpolation (
