hi there
I am trying to write a program to process camera preview data on-the-
fly, and display the results as (semitransparent) overlays.
I found one example that is particularly useful:
http://nhenze.net/?p=172
the source code is at http://nhenze.net/uploads/OpenGL_Cam_1_2.zip
In this sample, two Views are used, one SurfaceView for camera preview
(CamLayer.java), one GLSurfaceView for showing the processed image
(GLLayer.java). Unfortunately, the sample code maps the image to a
rotating cube, while in my case, I just need to match the view with
the camera preview in the background.
I am new to OpenGL. I am wondering if there is a simple way to display
a 2D texture on a GLSurfaceView that matches the preview SurfaceView?
Appreciated if there are any suggestions.
