How to draw two or more triangles in OpenGL? - Stack Overflow
2020年12月21日 · That's 1 triangle. Adding more triangles, i.e. 3 sets of 3 vertices, to this array is all you need to do, along with extending the g_color_buffer_data array and changing verticeCount accordingly. So this:
opengl - GL_TRIANGLE FAN Explanation - Stack Overflow
You can use a triangle strip, but you need to strategically duplicate vertices at the end of the strip to move to the next strip. The duplicated vertices create empty triangles, which OpenGL ignores. However, using straight-up triangles is certainly more straightforward.
In what order should I send my vertices to OpenGL for culling
@genpfault So as long as I'm sending vertices of triangles in counter-clockwise order (or in clockwise order in DirectX), one triangle at a time, it doesn't matter which vertex I start with. This triangle will be a front facing one and as such it will be rendered in the specific frame. Got it. Thank you. By the way, this is a great answer. –
opengl - Cube using single GL_TRIANGLE_STRIP - Stack Overflow
Draw a triangle edge along each face between the two black corners. That way, the diagonals form a tetrahedron inside the cube. For the [0,1]³ cube, a possible sequence of coordinates would be the following:
c++ - OpenGL drawing Triangles only white - Stack Overflow
I don't see how your triangle could be white if you output vec4(0.5, 0.3, 0.1, 1.0) in your shader. Change stuff in your fragment shader and vertex shader and see what effect it has, something may have gone wrong when creating your shader program.

2019年11月27日 · Using Triangle Strip we will be able to get the following output, using those given vertices. Triangle Fan. Where a Triangle Fan is also a set of connected triangles, though all these triangles have a common vertex, which is the central vertex. In OpenGL the central vertex is the first given vertex, in the Triangle Fan. Example of Triangle Fan
