android - How to use OpenGL by using OpenCV Camera -


i'm using org.opencv.android.javacameraview opencv4android preview camera view , use opencv process pic.
want use opengl draw on view.
no idea so.
can directly draw on mat opengl or must draw opengl images on javacameraview?

the layout looks this:

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:opencv="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_camera" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="0dp" android:paddingbottom="@dimen/activity_vertical_margin" android:paddingleft="@dimen/activity_horizontal_margin" android:paddingright="@dimen/activity_horizontal_margin" android:paddingtop="@dimen/activity_vertical_margin" tools:context="com.croxx.op3d.cameraactivity">  <org.opencv.android.javacameraview     android:id="@+id/camera_view"     android:layout_width="match_parent"     android:layout_height="match_parent"     opencv:camera_id="any"     opencv:show_fps="true"     />

and activity implements camerabridgeviewbase.cvcameraviewlistener2 :

public class cameraactivity extends appcompatactivity implements camerabridgeviewbase.cvcameraviewlistener2 { ... ... }

and using camerabridgeviewbase :

private camerabridgeviewbase mcvcamera;

and using these codes in oncreate :

mcvcamera = (camerabridgeviewbase) findviewbyid(r.id.camera_view);  mcvcamera.setcvcameraviewlistener(this);

iOS: Performance of reloading UIImage(name:...) -

i have tableview , each row has icon. 90% of rows have same icon. in cellforrowatindexpath method load image assets folder this: var cellimage = uiimage(named: "myimage") does pose performance problem? os somehow smart enough it's same image each time? better if loaded image once , saved in class variable , assigned each time? uiimage 's named: api does kind of caching. if @ uiimage's documentation , states: use init(named:in:compatiblewith:) method (or init(named:) method) create image image asset or image file located in app’s main bundle (or other known bundle). because these methods cache image data automatically, recommended images use frequently.
