Does Cocos2d-x support ETC2 textures? -

-

i'm building game , i'm supporting following texture formats:

  • atc
  • dxt
  • png
  • pvr

i'd add support etc2 (etc1 won't work because of our graphics require alpha channel). cocos2d-x support etc2 textures?

no.

but 2 things.

cocos2d-x doesn't have etc2 defines in cctexture2d.h. need add etc2 defines yourself.

and cocos2d-x uses opengl es 2.0 context, @ least, on android.

https://github.com/cocos2d/cocos2d-x/blob/v4-develop/cocos/platform/android/java/src/org/cocos2dx/lib/cocos2dxglsurfaceview.java#l76

this.seteglcontextclientversion(2);

so using etc2 glcompressedteximage2d needs these extensions.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
