    What is the efficient way to map four images to one plane?

    version: opengl es 3.0

    I have four cameras, and need to map the four images from cameras with textures to the area like this image.jpg,so what is the most efficient way to this purpose?

    Render 8 triangles (2 for each trapezoid).

    But you don't state how they are to be mapped. With the fixed-function pipeline, you're limited to a projective mapping. If you want a bilinear mapping, you'll need to use a fragment shader.

    This looks a lot like this.
