3. _D_a_t_a_b_a_s_e__L_o_a_d_e_r_s
OpenGL Performer provides an extensive set of dynamic shared
objects for loading databases of different file formats.
OpenGL Performer applications can do run-time look-ups for
finding DSOs for a file of a particular format based on the
suffix of the file name. The DSOs for these loaders are
provided as part of the OpenGL Performer execution
environment.
Loaders are provided for several Silicon Graphics data
formats (_b_i_n, _c_s_b, _g_f_o, _i_m, _i_v, _p_f_b, _p_f_s, _p_h_d, _p_t_u, _s_g_o,
etc.) as well as many popular formats including Autodesk's
_d_x_f and _3_d_s, Coryphaeus' _d_w_b, Medit's _m_e_d_i_t, MultiGen-
Paradigm, Inc's _f_l_t, Wavefront's _o_b_j, and many others.
3.1 _l_i_b_p_f_d_b__D_a_t_a_b_a_s_e__L_o_a_d_e_r_s
_l_i_b_p_f_d_b is a collection of independent libraries (one for
each supported file format, in each of O32, N32, and N64)
that read or write a particular scene description file
format. These loaders are implemented using the IRIX
Dynamic Shared Object facility and are demand loaded as
needed. The file loader DSO provided with the OpenGL
Performer execution environment include:
