android - OpenGL ES Degenerate Triangles With TRIANGLE_FAN? -


in opengl es, possible use degenerate triangles (triangles 0 area) separate triangle_fan objects in vertex array? or possible triangle_strip?

if answer no, best way batch multiple triangle_fan vertex array draw calls one?

you correct, answer no, since triangle fan triangles share same vertex.

if want batch multiple triangle fans better use vertex buffer objects or vbo's gl_triangles mode instead. there small index buffer overhead, provide better flexibility.
