#1 Openspace3D » Google Play's target API level requirement » 17-Jul-2019 22:07:52

From https://developer.android.com/distribut … t-sdk.html :
When you upload an APK, it needs to meet Google Play’s target API level requirements. Starting August 1, 2019, Google Play requires that new apps target at least Android 9.0 (API level 28), and that app updates target Android 9.0 from November 1, 2019. Until these dates, new apps and app updates must target at least Android 8.0 (API level 26).

I have created an APK for arm64 with Openspace3D 1.80 and after the upload Google Play says my app targets API level 26. Can I target level 28? Maybe with a future update of the Android plugin?

Other problem with my AR app is the size of the APK using the Default option. It seems to contain the 32 and 64 bits versions, so the size is greater than 100 MB and Google Play does not accept the APK. I have to create both versions separately (arm32 and arm64). That is the solution?

I have created an app of Augmented Reality for the TENTE Expo 2017:

TENTE is a discontinued spanish construction game similar to Lego but incompatible (not a clone). In the 80's it was more popular than Lego in Spain, but the factory broke in the 90's because of the crisis and bad decisions. Another company bought the game, but a decade without new models has passed. TENTE was also distributed in France, Italy, Germany, Mexico, Brazil, USA (Hasbro) and Japan (Nomura Toys).

Since 2012 a group of fans organize an annual exhibition in Spain with original and custom models, and posters. For many of these expos I have created an augmented reality app for Android. Previously using Unity + Vuforia, but after Vuforia changed its license, I looked for alternatives and found OpenSpace3D. big_smile For this app, I have modified the ARCards demo. The 3D models, most of them animated, were designed by fans using 3D bricks instead of the real ones (we have adapted to TENTE the LDraw software originally made for Lego). Many of the posters at the expo have a model whose photo is the marker required by the app, including the main poster.

Thanks to arkeon for answering my questions during the development of this app. wink

OK. Another question about the screenshots. The orientation of my android app is landscape and all the captured images are also landscape. But people could take a shot in portrait and then they'll see the image is rotated (landscape instead of portrait). I suppose the solution is to use the Orientation sensor plugit whose Z value is (-45, 45) in landscape, (-135, -45) in portrait and so on. But I don't know what element to change with that info ¿the active camera?

#5 Re: Openspace3D » Date format of Screenshot PlugIT » 14-May-2017 11:47:35

The last solution works, but I don't want two pictures. I'm back to my original question, when the ".png.jpg" trick creates a jpg with 75% quality. I don't know what function is the responsible, but maybe it has the quality as parameter and it's called with the 75 value or the default value is 75. In that case I would want to change it to 90 or 95 (good quality for jpg and smaller size than png).

#6 Re: Openspace3D » Date format of Screenshot PlugIT » 13-May-2017 22:09:22

I'm trying first in Windows but I've also tried with Android. Using _BTSAVEbitmap gives also a png.

The code after all these changes, in case I've made some mistake:

fun cbTakeShot(inst, from, action, param, rep, p) =
  let V3DgetSessionView c3dXsession -> viewstr in
  let p -> [filePrefix only3d] in
  let (localtime time) -> [seconds minutes hours day month year wd yd] in
  let strcatn filePrefix::(itoa year)::(if month<10 then "0" else "")::(itoa month)::(if day<10 then "0" else "")::(itoa day)::"_"::(if hours<10 then "0" else "")::(itoa hours)::(if minutes<10 then "0" else "")::(itoa minutes)::(if seconds<10 then "0" else "")::(itoa seconds)::(if only3d then ".png" else ".jpg")::nil -> file in
  (
    if (only3d) then 
    (
	  if (SO3BufferWriteContent viewstr.V3D_buffer (_getmodifypack file)) == nil then nil else
      (
        let _LDalphaBitmap _channel (_checkpack file) -> abmp in
        let _GETalphaBitmaps abmp -> [bmp alpha] in
        (
          _BTSAVEbitmap bmp (_getmodifypack (strcat file ".jpg")); // jpg 95%
        
          //delete png file
          _deletepack (_checkpack file);
          
          //free loaded bmp
          _DSalphaBitmap abmp;
        );
        SendPluginEvent inst "Saved" file nil;
      );      0;
    )
    else
    (
      let _GETscreenSize -> [sw sh] in
      let _FILLbitmap _CRbitmap _channel sw sh 0x0 -> bmp in
      let _CAPTUREscreen bmp 0 0 sw sh 0 -> bmp in
      (
        _SAVEjpeg bmp _getmodifypack file 75;
        _DSbitmap bmp;
        SendPluginEvent inst "Saved" file nil;
      );
      0;
    );
  ); 
  0;;

#7 Re: Openspace3D » Date format of Screenshot PlugIT » 13-May-2017 20:22:26

I've replaced the original code

if (SO3BufferWriteContent viewstr.V3D_buffer (_getmodifypack file)) == nil then nil else
        SendPluginEvent inst "Saved" file nil;

with yours but it doesn't work. When the extension code is the original

if only3d then ".png" else ".jpg"

the result is a png. And with the trick ".png.jpg" a jpg 75% quality is created. It's the same as before. sad

#8 Re: Openspace3D » Date format of Screenshot PlugIT » 13-May-2017 17:51:47

Well, the problem of the android viewers with the pngs was due to the path of the file prefix: "%pictures%/screenshots/myprefix". Just reducing to one folder "%pictures%/myprefix" solves the problem. Anyway I would prefer jpgs with higher quality instead of pngs because of the smaller size.

#9 Re: Openspace3D » Date format of Screenshot PlugIT » 13-May-2017 17:36:08

Good to know the function alternative, iri.

I've found that the files saved as ".png.jpg" are jpgs with 75% quality, not pngs. yikes I've read in this forum that png was used because 3D is RGBA, I think, but it seems that the program uses the format indicated in the extension. Any possibility to change  by code the quality used to save jpgs?

#10 Re: Openspace3D » Date format of Screenshot PlugIT » 13-May-2017 10:49:14

My app have to be finished in less than two weeks so I have modified the code of the Screenshot PlugIT. In cscreenshot.pkg I've replaced the line:

let strcatn filePrefix::(strtrim strreplace (strreplace (ctime time) " " "_") ":" "-")::(if only3d then ".png" else ".jpg")::nil -> file in

by these ones:

let (localtime time) -> [seconds minutes hours day month year wd yd] in
let strcatn filePrefix::(itoa year)::(if month<10 then "0" else "")::(itoa month)::(if day<10 then "0" else "")::(itoa day)::"_"::(if hours<10 then "0" else "")::(itoa hours)::(if minutes<10 then "0" else "")::(itoa minutes)::(if seconds<10 then "0" else "")::(itoa seconds)::(if only3d then ".png.jpg" else ".jpg")::nil -> file in

It's my first time with Scol code, so surely there is a better code to do the same. I have also changed the extension string ".png" to ".png.jpg" because many Android galleries don't detect PNGs but they are capable of showing them with the jpg extension (I don't know the reason, but it works).

The file name of the image saved with the Screenshot PlugIT is "mon_may_01_15-55-10_2017" when the date is "Monday May 1, 2017 15:55:10". I would prefer "20170401_155510", shorter and better for sorting. Can I use another date format?

#12 Re: Openspace3D » Problem trying to execute examples in Raspberry Pi 3 Model B » 15-Apr-2017 22:33:42

Sorry, I didn't notice your last post until now. Meanwhile I split the model in parts and a new problem appeared: the model showed no colour, although it has coloured faces (no problem in Windows or Android). The solution was to use a texture. hmm It runs smoothly in the RPi3 with all the parts adding a total of 58k vertices.

For your test, this is an old version of the mesh with near 89k vertices: https://www.dropbox.com/s/vblm8bb6dbeul … o.zip?dl=1

It is a mesh from a LDraw model, after removing many of the internal faces. The fact of being virtual bricks results on unoptimized meshes.

#13 Re: Openspace3D » Problem trying to execute examples in Raspberry Pi 3 Model B » 9-Apr-2017 16:50:08

I can try to separate my model in several models and show them with the same marker. Or decreasing the number of vertices is the only option?

I'm not sure how to check it. The 3D model is an OBJ exported from Blender with the default parameters. It only has face colours.

The original ar-cards demo works with 256 MB. smile Also my modification but only the models from the demo, so now the problem seems to be the 65536 vertices limit. The log shows no warning about that and it's near identical to the ar-cards log. The first difference is:

Mesh: Loading /usr/share/PROGRAM-NAME/partition/assets/models/converted/MY-MODEL/meshes/castillomota_castillo_cartillo_mota-tan2.mesh.

Once running there are several lines like this:

Page[3]  pre: 40, aft: 40, error = 1,051564

And I think the next line appears when the marker of my model is detected, but the program doesn't show my mesh:

Material scheme converted from Default to ShaderGeneratorDefaultScheme on material : ASSET/TransShadow with group : 0.main82.trex

I replaced the trex with my mesh, so some names maintain the "trex". My mesh doesn't have textures, only colours.

For comparison, when the Andy marker is detected and Andy appears:

Material scheme converted from Default to ShaderGeneratorDefaultScheme on material : ASSET/TransShadow with group : 0.main12.andy

After replacing those files, ar-piano works in the raspberry. smile But not my modification of arcards. After the initial logo, the screen is white. It works in Windows. In my modification I've removed all the blocks except trex, pterodactylus, andy and drawfish, and replaced the mesh of trex with an OBJ with 100k faces and 65k vertices. So maybe this mesh is excesive or I should increase the memory of the RP3 dedicated to GPU.

Although now I'm not near the raspberry, I'm sure that the camera option is enabled but the others are disabled (I2C, spi). I'll enable them and use a screen. I suppose my system has the last version (updated a couple of days ago), but I'll check it.
