Question

I’ve drawn multiple 3d cubes objects using following function:

gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, vertexCount);

Now, I have to draw gridline too on it.So can you please tell me how to draw these gridlines(boxes) on it using opengl.

Thanks.

Answer 1

If I understand you correctly you want to draw lines?
If so, all you have to do is create vertices as usual and draw them using GL10.GL_LINES instead of GL10.GL_TRIANGLES (or triangle_strip).
You can change the width of the lines by calling glLineWidth()
