WebIn OpenGL ES 1.x, you can use several methods: glDrawArrays glDrawElements: TRIANGLES or TRIANGLES_STRIP (denormalized triangles) VBO glDrawTexfOES (you need to verify that you have this extension) glDrawTexfOES is the faster method to draw efficiently quads but it is not available on old phones. VBO is efficient for static quads. Web4 de mai. de 2013 · Hi I have a header file like that. I’m willing to create a grid. By using OpenGl and C++. The problem is in there cpp file.
