Can't tell if there are any other problems with your code, but the missing VAO is probably the main one. I suggest you read the whole text on the site I linked and follow the instructions to render a single triangle. A work around is to draw the triangles with GL_FILL first in background color (in my case, white), and then draw the edges separately. But doing so results in artifacts similar to the z-fighting phenomenon, i.e., some edges seem thinner than others or even vanish, as shown below. can botfly infect humans

WebGL_TRIANGLE_FAN Use this primitive to draw a fan of triangles that share edges and also share a vertex. Each triangle shares the first vertex specified. If the application specifies a sequence of vertices v, OpenGL renders a triangle using v 0, v 1, and v 2; another triangle using v 0, v 2, and v 3; another triangle using v 0, v 3, and v 4; and ... WebThe glDrawArrays function takes as its first argument the OpenGL primitive type we would like to draw. Since I said at the start we wanted to draw a triangle, and I don't like lying to you, we pass in GL_TRIANGLES.
