Im having doubts on how to work with different screen sizes. Im giving the left top corner to (0,0), and for the right bottom corner i give (screen_width, screen_height). In this way i always know the size of the screen, and keep the aspect ratio of the objects i draw. But what happens when it try it on a smaller/higher screen? well, i keep having the aspect ratio, but have a look to this example:
Screen 1 (landscape):
width = 800
height = 400
I draw an object in (780,380), just in the right bottom corner. See screen 2 example:
Screen 2 (landscape)
width = 600
height = 300
They have same aspect ratio, but if in my code i draw something on (780,380), i some screens it would be visible, and in others it wont. Im thinking in converting coordinates, for example (600*780)/800 = 585, so i have the corresponding coordinates for both screens. But i dont know if this keep the acpect ratio, and i should apply it just not to coordinates, also for object dimensions.
Here is how i setup ortho view:
- Code: Select all
public void seUpOrthoProjection(int w, int h)
float c_matrix = new float;
float p_matrix = new float;
Matrix.orthoM(p_matrix, 0, 0, w, h, 0, -1.0f, 1.0f);
Matrix.setLookAtM(c_matrix, 0, 0, 0, 1, 0f, 0f, 0f, 0f, 1.0f, 0.0f);
Maybe this is a stupid question, but i dont know what is the way to work with it.
Thanks in advance!
