Does version OpenGL 3+ only uses “GL_TRIANGLES” ?
That’s what I read, but in the documentation for OpenGL 3.3, http://www.opengl.org/sdk/docs/man3/, “glDrawArrays()” takes the following parameters:
GL_POINTS,
GL_LINE_STRIP,
GL_LINE_LOOP,
GL_LINES,
GL_LINE_STRIP_ADJACENCY,
GL_LINES_ADJACENCY,
GL_TRIANGLE_STRIP,
GL_TRIANGLE_FAN,
GL_TRIANGLES,
GL_TRIANGLE_STRIP_ADJACENCY,
GL_TRIANGLES_ADJACENCY
You mean “instead of also offering GL_QUADS and GL_POLYGON”?
Yes indeed. Quads and Polygons have been removed altogether. Most polygons needed to be tesselated into triangles anyway, since OpenGL can deal with convex polygons only (convex also imples planar!). Similar holds for quads.
Lines and points remain to be supported of course.
