I am currently playing about with lesson 08 here
http://insanitydesign.com/wp/projects/nehe-android-ports/
I would like to change the background colour from black to white. In order to do this at the start of onDrawFrame() I have called
gl.glClearColor(1.0f, 0.0f, 0.0f, 0.0f);
This does indeed set a white background screen, but also results in nothing else showing up on the screen! Clearly this is therefore an incorrect method, but why, and how do I fix it?!
Many thanks in advance.
Edit (5 days later): Does nobody know at all?!!
The white screen is because you have set the alpha value to 0.0f.
The parameter signature is:-
gl.glClearColor(float red, float green, float blue, float alpha)
where floats are any value between 0.0 to 1.0.
More the float value of alpha more opaque the screen is.
