Hány csúcspontot fog tartalmazni az alábbi vbo?

unsigned

int vbo;

glGenBuffers(1,

&vbo); 

glBindBuffer(GL_ARRAY_BUFFER,

vbo);

double vertices[]

= {1,2,3,4,5,6,7,8};

glBufferData(GL_ARRAY_BUFFER, sizeof(vertices), vertices, GL_STATIC_DRAW);   

glEnableVertexAttribArray(0);  // AttribArray 0

glVertexAttribPointer(0, 1,

GL_FLOAT, GL_FALSE, 0, NULL);
