Obj model loading error
« on: March 04, 2013, 06:31:30 pm »
Hi,

 I have downloaded obj file from this site http://people.sc.fsu.edu/~jburkardt/data/obj/obj.html and tried to use it in my application ( JPCT-AE) got following error

03-04 22:58:47.749: E/AndroidRuntime(22464): java.lang.RuntimeException: [ 1362418127753 ] - ERROR: java.lang.RuntimeException: [ 1362418127740 ] - ERROR: Unsupported Texture width: 929

Like the docs state, texture width and height has to be a power of 2. 929 isn't a power of 2.

But docs says Texture size has to be a power of 2. Any texture using another width and/or height will automatically be scaled to a width of 256 pixels. jPCT will print out a warning in this case.

No, that's what the docs of the desktop version state....because that's what the desktop version does. The Android version raises an error and so say the docs.

Hi,

 How do i find out texture height and width is power of 2? If it is not, is possible to convert texture width and height?

Thanks & Regards,
Prakash V

Power of 2...4,8,16,32,64,128,256,512,1024...it shouldn't be too hard to find out if width and height are any or those. If they aren't, take your prefered image editing tools and rescale them.
