Código de colores OpenGl (Open Graphics Library) es una especificación estándar que define una API multilenguaje y multiplataforma sirve para escribir aplicaciones que producen gráficos 2D y 3D También es utilizada en la creación de videojuegos, compite con Direct3D.
Colores OpenGl Graficos 2D y 3D
Para color de fondo: |
| gl.glClearColor (flotante rojo, flotante verde, flotante azul, flotante alfa) |
| glClearColor (0.0,0.0,1.0,0.0); // azul oscuro |
| Para color de relleno |
glColor4f(1.0f, 0.0f, 0.0f, 0.0f);//red |
| glColor4f(1.0f, 1.0f, 1.0f, 0.0f);//white |
| glColor4f(1.0f, 1.0f, 0.0f, 0.0f);//yellow |
| glColor4f(1.0f, 0.0f, 1.0f, 0.0f);//purple |
| glColor4f(0.0f, 1.0f, 1.0f, 1.0f);//light blue |
| glColor4f(1.0f, 0.5f, 0.0f, 0.0f);//orange/brown |
| glColor3f(0.0f, 1.0f, 0.0f);//Green |
| glColor3f(0.0f, 0.0f, 1.0f);//Blue |
| glColor3f(0.5f, 1.0f, 1.0f);//cyan |

Ejemplo de un cubo 3D Código de colores OpenGl
glBegin(GL_POLYGON);
glColor3f( 1.0, 0.0, 0.0 ); glVertex3f( 0.5, -0.5, -0.5 ); // P1 es rojo
glColor3f( 0.0, 1.0, 0.0 ); glVertex3f( 0.5, 0.5, -0.5 ); // P2 es verde
glColor3f( 0.0, 0.0, 1.0 ); glVertex3f( -0.5, 0.5, -0.5 ); // P3 es azul
glColor3f( 1.0, 0.0, 1.0 ); glVertex3f( -0.5, -0.5, -0.5 ); // P4 es morado
glEnd();
