Draw a triangle opengl
WebThis is a simple array of integers that encode each triangle (a,b,c,a,b,d would encode two triangles abc and abd). 这是一个简单的整数数组，用于编码每个三角形（a，b，c，a，b，d将编码两个三角形abc和abd）。 All works just fine, but I would like to render my primitives using triangle fans instead of triangles.

WebA triangle strip in OpenGL is a more efficient way to draw triangles with fewer vertices. After the first triangle is drawn, each subsequent vertex generates another triangle next to the first triangle: every 3 adjacent … WebThis is something you can’t change, it’s built in your graphics card. So (-1,-1) is the bottom left corner of your screen. (1,-1) is the bottom right, and (0,1) is the middle top. So this triangle should take most of the screen. Drawing …
WebIt instructs OpenGL to draw triangles. glColor3f tells OpenGL which color to use. A color is defined as a pair of three floating points representing red,green and blue.
