opengl - How to create viewer for JT 3D file format -

-

i want create viewer can view/render jt file format. know there 1 viewer available jt2go want create 1 own, jt2go not open source.

my requirement not high , don't require features jt2go has, want render 3d file, no layering or selecting of individual components required. plane viewer.

start getting spec at:

http://www.plm.automation.siemens.com/en_us/images/jt_v95_file_format_reference_rev-a_tcm1023-111987.pdf

and write library read file. spec looks big straight forward implement. think should possible access elements of file without keeping whole datastructure in memory.

when programming viewer part, don't use opengl directly, use scene graph library. (openscenegraph first 1 pops mind)

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
