GL.TRIANGLES

Description

Режим для Begin: визуализация треугольников.

Draws triangles using each set of 3 vertices passed. If you pass 3 vertices, one triangle is drawn, where each vertex becomes one corner of the triangle. If you pass 6 vertices, 2 triangles will be drawn.

To set up the screen for drawing in 2D, use GL.LoadOrtho or GL.LoadPixelMatrix. To set up the screen for drawing in 3D, use GL.LoadIdentity followed by GL.MultMatrix with the desired transformation matrix.

See Also: GL.Begin, GL.End.
