-
- Welcome to the OpenGL Performer execution-only environment
- (eoe).
-
- Note: These release notes apply to the OpenGL Performer 2.5
- for IRIX product and its 100% binary-compatible
- minor-release successors (versions 2.5.1, 2.5.2,
- etc). OpenGL Performer 2.5 for Linux release notes
- are available on the Linux product CD, and are
- installed to /_u_s_r/_d_o_c/_p_e_r_f_o_r_m_e_r-_2._5.
-
- OpenGL Performer is a powerful and comprehensive programming
- interface for developers creating real-time visual
- simulation and other performance-oriented 3D graphics
- applications. It simplifies development of complex
- applications used for visual simulation, simulation-based
- design, virtual reality, interactive entertainment,
- broadcast video, architectural walk-through, and computer
- aided design.
-
- OpenGL Performer 2.5 is built atop the industry standard
- OpenGL graphics library, includes both ANSI C and C++
- bindings, and is available for both the IRIX operating
- system and GNU/Linux. It forms the foundation of a powerful
- suite of tools and features for creating real-time visual
- simulation applications on IRIX & Linux systems. OpenGL
- Performer 2.5 supports all Silicon Graphics running IRIX 6.5
- or later, as well as IA32-based systems with Linux.
-
- OpenGL Performer is an integral part of the InfiniteReality,
- VPRO, Impact, and O2 visual simulation solutions and in
- particular, provides interfaces to the advanced features of
- InfiniteReality class graphics. OpenGL Performer is
- compatible with all SGI graphics platforms running IRIX or
- Linux, and attains maximum performance on each. OpenGL
- Performer is the flexible, intuitive, toolkit-based solution
- for developers who want to optimize performance on Silicon
- Graphics systems.
-
- The OpenGL Performer execution environment contains the
- dynamic shared objects (DSOs) for runtime linking for
- applications based on OpenGL Performer. The binary-
- compatible maintenance releases of previous versions of IRIS
- Performer (2.4.4, 2.2.15, 2.1.5 and 2.0.7) are included as
- well. The OpenGL Performer DSOs are identified by DSO
- version so that execution environments from previous OpenGL
- Performer releases can co-exist simultaneously on the same
- system. This allows you to run a Performer application that
- was dynamically linked with any release. The run-time IRIX
- linker, rld, will automatically select the proper DSO to run

- any given Performer application. Similar arrangement is
- made on Linux systems as well.
-
- OpenGL Performer 2.5 contains many new features for
- supporting Image-Based Rendering, Real-Time Shadows, Light
- Shafts, Dynamic Shader Effects, and other advanced graphics
- features, as well as many important architectural and
- performance enhancements.
-
- To get further acquainted with the new features of OpenGL
- Performer 2.5 we recommend that you read the main OpenGL
- Performer man page ("man performer") and that you install
- and check out the following demonstrations _p_e_r_f_l_y, the basic
- OpenGL Performer viewer, _c_l_i_p_f_l_y, _a_s_d_f_l_y, _f_o_g_f_l_y, _r_o_t_o_r_w_a_s_h
- and many new sample programs (See Chapter 2 of these release
- notes for installation information).
-
- OpenGL Performer consists of our main library, _l_i_b_p_f, three
- associated utility libraries, _l_i_b_p_f_d_u, _l_i_b_p_f_u_i, and
- _l_i_b_p_f_u_t_i_l, and libraries for loading databases of different
- file formats that are part of the _l_i_b_p_f_d_b collection.
