Compiling Draco library on Windows platform

window Platform compilation draco library

The previous article talked about three.js Use VR effect Front end use three.js load Obj（ 3D model file ）

Also attached linux compile draco The process of . Also provided window Under the platform .exe file

However, a problem encountered recently is , The compiled code is old ,draco Also updating iterations . So I'll make it up today window Platform compilation draco library

Environmental preparation

My computer is not installed python Environmental Science

If you know why, I hope you will give me some advice

For example CMD Enter the corresponding directory in , hold testdata/360.obj Put it in and exe Statistical catalog , perform ：

./draco_encoder.exe -i testdata/360.obj -o testdata/360.obj.drc
