GL_LINE_STRIP - Using Textures ? iOS GLKit

Question

Is it possible in OpenGL ES 2.0 to use GL_LINE_STRIP to draw a shape and then apply a texture to that shape ?

E.g if I draw a triangle can I then apply a triangle texture ?

Answer 1

GL_LINE_STRIP draws only lines. If you want polygons filled in (whether with color, lighting, or texturing), you need one of the solid polygon modes: GL_TRIANGLES, GL_TRIANGLE_STRIP, or GL_TRIANGLE_FAN.

If you want to both fill and stroke your polygons, you'll need two draw calls, one with each mode. And if you're using depth testing, you'll probably want to look into glPolygonOffset to avoid z-fighting.
