javascript - Define transparent material in JSON Model format 3.1 -

-

i ask, how define transparent material in json model format 3.1. have tried following json without success:

 {     "metadata": {             "formatversion" : 3      },     "materials": [{         "dbgcolor" : 15658734,         "dbgindex" : 0,         "dbgname" : "dummy",         "illumination" : 2,         "opticaldensity" : 0.5,         "transparency" : 0.5,         "colorambient" : [ 0.9, 0.1, 0.1 ],         "colordiffuse" : [ 0.1, 0.7, 0.1 ]     }],     "vertices": [0,0,0, 100,0,0, 100,100,0, 0,100,0 ],     "normals": [],     "colors": [1,0,0, 0,1,0 ],     "uvs": [],     "faces": [67, 0,1,2,3,0, 1] }

i have tried play different values illumination, optical density , transparency, no luck.

thanks jan

you need set transparent: true , transparency: 0.5. latter maps opacity.

"materials": [  {     "dbgcolor" : 15658734,     "dbgindex" : 0,     "dbgname" : "dummy",     "transparent" : true,     "transparency" : 0.5,     "colorambient" : [ 0.9, 0.1, 0.1 ],     "colordiffuse" : [ 0.1, 0.7, 0.1 ] }],

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
