Hello All,
My game runs fairly well on my phone, but i want to increase the
performance by using opengl.
However currently i use the Canvas.
I am a beginner in opengl.
I have to port all my drawing code to opengl. However can somebody
give me directions.
For example how do i do the following in opengl:
c.save();
c.scale(0.3f+scale, 0.3f+scale, width/2, height/2);
c.drawBitmap(
bMsg.bitmap,
width/2 - bMsg.bitmap.getWidth()/2,
dy+height/2 - bMsg.bitmap.getHeight()/2,
MESSAGE_PAINT
);
c.restore();
And why cant i just use Canvas as an abstraction layer (facade) for
opengl.
An implementation of canvas could call the correct opengl methods in
order to render.
Why do i have to port all my code. I thought the canvas was a good
abstraction interface to a drawing surface,
why do i have to bother with opengl?
It looks like this is possible, when is see the following contructor:
"public Canvas (GL gl)"
Also the this seems usefull.
SURFACE_TYPE_GPU Surface type: creates a surface suited to be used
with the GPU
So what should i do?
Re implementing the GamePainter completely and call opengl functions
directly?
Or is there some kind of abstraction mechanism, so that i can use
OpenGL with just a few lines of code?
