GiD_Project view <option> ?<value>?
To handle view parameters
<option> could be
clip_planes_x|clip_planes_y|clip_planes_z|clip_planes_margin|rotation_vector|rotation_factor|rotation_matrix|rotation_center|perspective_distance|perspective_ortho_near|perspective_ortho_far|perspective_factor|perspective_view|view_mode|render_mode|ligthlight_vector
if <value> is provided then the value is set, else the current values are get
...
GiD_Project view render_mode ?value?
Current render mode (integer)
GiD_Project view ligthlight_vector ?{x y z}?w?}
Light direction .
If w is missing the is defaulted to 0.0 and the ligth will be directionalin screen space (not in world space): x = horizontal, y = vertical, z = towards the user
The light is directional, not punctual, and the modulus doesn't matter (it is not necessary to be an unitary vector)
If {x y z} argument is missing it returns the current light direction
