android - ETC1 texture support on Samsung Galaxy ACE GT-S5830 -


I have this Samsung Galaxy ACE GT-S 5830 Android phone, which is an Adreno-200 GPU.

I think it is possible to support Etc. (Ericsson Compression Format). But feel like it could not load them.

However the gl.glGetString (GL10.GL_EXTENSIONS) function is GL_OES_compressed_ETC1_RGB8_texture extension.

but android.opengl.ETC1Util.isETC1Supported () false returns ??? it's so weird.

I have converted my files into .pkm format. In this way I am loading the texture, but I see that the white screen that shows the texture does not load. : is the inputstream = _context.getAssets (). Open ("etc / hands_tex.pkm"); Gl.glActiveTexture (GL10.GL_TEXTURE0); // Gl.glBindTexture (GL10.GL_TEXTURE_2D, glTtextureId) for texture loading texture unit; {ETC1Ttexture etc1tex = ETC1Util.createTestructure (try); Bytebuff BB = etc 1X.tex.getData (); Gl.glCompressedTexImage2D (GL10.GL_TEXTURE_2D, level, ETC1.ETC1_RGB8_OES, etc1tex.getWidth (), etc1tex.getHeight (), 0, bb.capacity (), bb); } Hold (IOException e) {e.printStackTrace (); }

However the works up to ETC1Util.createTexture () creates the texture object in calls and memory.

I have never used Java GL but I have written native OpenGL code for Android which is ETC 1 uses compression so I hope I can help. ETC1 is a common texture format for Android and expansion shows that your device supports it. :)

Something is unknown here that you should try and be resolved

your texture is loading and the display code may be faulty, not ETC1 Part.. You should probably try to swap ETC 1 and use it to display non-compressed secure formats such as 32 bits correctly.

Then use a simple 32x32 ETC1 texture to try to influence the size of the non-square NPOT. > gl.glCompressedTexImage2D (GL10.GL_TEXTURE_2D, Level, ETC1.ETC1_RGB8_OES, 32, 32, 0, 512, bb: glCompressedTexImage2D Use coded values);

Make sure the BB is valid, the return code from glCompressedTexImage2D is also very useful, as the course is NULL valid parameter.

If you have already tried to do this then sorry. Hope is some use of it, Andy

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
