3D Graphics with OpenGL - The Basic Theory
WebglTranslatef (-1.5f, 0.0f, -6.0f); // Move left and into the screen View Transform The default camera position is: gluLookAt (0.0, 0.0, 0.0, 0.0, 0.0, -100.0, 0.0, 1.0, 0.0) That is, EYE= (0,0,0) at the origin, AT= (0,0,-100) pointing at negative-z axis (into the screen), and UP= (0,1,0) corresponds to y-axis. WebIn OpenGL this matches glVertex3f(x,y,z); on other graphics APIs the same functionality is emulated. This function can only be called between GL.Begin and GL.End functions. … share watch face
