Gles30.gldrawarrays Drawing shapes

Gl_points, draw some.

Gl_lines Draw line, 2-point connection

Gl_line_loop let the line loop closed

Gl_line_strip draw lines are not closed

Gl_triangles draw a triangle, three points to draw a

Gl_triangle_strip each vertex and 2 other vertex joins to form a triangle

Gl_triangle_fan draw a triangle fan, you can draw shapes like circles
