- Subject: -1- GENERAL QUESTIONS
- Date: 06 May 1995 00:00:01 EST
-
- General questions.
-
- ------------------------------
-
- Subject: -2- What is Open Inventor?
- Date: 30 Apr 1994 15:45:00 CDT
-
- Open Inventor is an object-oriented 3D toolkit offering a
- comprehensive solution to interactive graphics programming problems.
- It presents a programming model based on a 3D scene database that
- dramatically simplifies graphics programming. It includes a rich set
- of objects such as cubes, polygons, text, materials, cameras, lights,
- trackballs, handle boxes, 3D viewers, and editors that speed up your
- programming time and extend your 3D programming capabilities.
-
- Open Inventor:
- o is built on top of OpenGL
- o defines a standard file format for 3D data interchange
- o introduces a simple event model for 3D interaction
- o provides animation objects called Engines
- o provides high performance object picking
- o is window system and platform independent
- o supports PostScript printing
- o encourages programmers to create new customized objects
- o is fun to use
-
- ------------------------------
-
- Subject: -3- What is IRIS Inventor?
- Date: 30 Apr 1994 15:45:00 CDT
-
- IRIS Inventor was the first release of Inventor; it is also known as
- Inventor 1.0 (Open Inventor is Inventor 2.0). It is built on top of
- IRIS GL rather than OpenGL, and has fewer features.
-
- ------------------------------
-
- Subject: -4- Is Inventor a format for 3D data?
- Date: 30 Apr 1994 15:45:00 CDT
-
- Inventor defines a powerful, extensible format for 3D objects and
- scenes. The Inventor format is the standard for 3D objects on
- Silicon Graphics machines, and may become the standard for all
- machines.
-
- However, Inventor is more than a 3D object file format; it is a
- complete toolkit for writing interactive, 3D applications.
-
- ------------------------------
-
- Subject: -5- Can I use Inventor to create 3D objects?
- Date: 30 Apr 1994 15:45:00 CDT
-
- Inventor is for programmers writing 3D applications, and does not
- directly provide any way for users to create 3D objects. Several
- Inventor applications have been written that create 3D objects.
- Showcase 3.0, which is bundled with IRIX, is a fairly simple
- example. A much more sophisticated modeller called Ez3d built on
- top of Inventor is available from Radiance Software International.
-
- ------------------------------
-
- Subject: -6- Is Inventor a user interface toolkit?
- Date: 30 Apr 1994 15:45:00 CDT
-
- Yes and no. Inventor contains mostly 3D objects. There is little in
- the way of conventional user interface objects such as buttons,
- dialogs, and menus. However, Inventor includes a full-fledged event
- model, a framework designed for 2D or 3D user interaction, and some
- manipulator objects for 3D user interface building. Note that the
- Inventor Xt Component and Utility Library includes some traditional
- 2D user interface widgets.
-
- ------------------------------
-
- Subject: -7- Is there a performance cost using a software layer on
- top of GL?
- Date: 30 Apr 1994 15:45:00 CDT
-
- Sometimes. Note that few GL programs achieve peak graphics
- performance. This is because most applications have natural
- application overhead, and also because many programmers lack a
- thorough understanding of the details and eccentricities of GL. If
- you are writing a simple display-only, immediate-mode GL program,
- then it will run faster using straight GL, but not much. However, if
- your program has scene traversal, interactivity, picking, bounding
- box calculations, and other object space tasks, then Inventor will
- perform better for you. This is because Inventor is specially tuned
- to make optimal use of GL on each SGI machine. Furthermore, Inventor
- supports render caching which results in peak GL performance in most
- cases.
-
- We have found that in many cases, Inventor programs run FASTER than
- the original GL program, and that the programmer productivity
- increases easily outweigh the overhead of the toolkit.
-
- ------------------------------
-
- Subject: -8- Does Inventor require C++?
- Date: 30 Apr 1994 15:45:00 CDT
-
- No. You can use the C API and never see or use C++. However,
- subclassing to extend the toolkit does require C++.
-
- ------------------------------
-
- Subject: -9- Does Inventor work with the GNU C++ compiler?
- Date: 30 Apr 1994 15:45:00 CDT
-
- No, Inventor requires SGI's C++ compiler. The GNU C++ compiler and
- SGI's C++ compiler produce incompatible code, and Silicon Graphics
- does not ship an Inventor library compatible with GNU C++.
-
- ------------------------------
-
- Subject: -10- Does Inventor have a Fortran or Ada API?
- Date: 09 Jan 1996 00:00:01 PST
-
- No. Silicon Graphics is, however, in the process of creating an Ada95
- binding for Open Inventor.
-
- ------------------------------
-
- Subject: -11- Where can I get detailed, technical information on
- Inventor?
- Date: 30 Apr 1994 15:45:00 CDT
-
- The Inventor Mentor, written by Josie Wernecke, is published by
- Addison-Wesley and is available in technical bookstores (ISBN
- 0-201-62495-8).
-

- specifically regarding: fields and isA.
- SoGLRenderAction Render Abort Callback Changes
- The render abort callback of the SoGLRenderAction no longer
- returns a simple Boolean value. Instead, it returns an abort
- code that is one of: CONTINUE, ABORT, PRUNE, or DELAY.
- CONTINUE is the same as returning FALSE in previous releases,
- and ABORT is the same as TRUE.
- New Manipulator for 3D Transformations
- A new manipulator, SoTransformerManip, has been added to the
- set of Inventor manipulators.
- OpenGL Texture Object Extension
- Open Inventor 2.1 makes use of the OpenGL extension for texture
- objects. Consequently, on systems where this OpenGL extension

- image files. The JPEG files are read using the fifth public
- release of the Independent JPEG's group free JPEG software.
- Picking vs. Viewing
- When in picking mode in any of the viewers, you can now
- temporarily switch to viewing mode by pressing the key. Note
- also that the manipulators now use the key as the modifier key,
- instead of the key.
- Disabling the Viewer Cursor
- The application can now set the cursor in the viewer windows
- directly, if it first disables the viewer cursor using
- SoXtViewer::setCursorEnabled().
- Targets for Copy and Paste

-
- Subject: -18- How hard is it to port from IRIS Inventor to Open
- Inventor?
- Date: 30 Apr 1994 15:45:00 CDT
-
- Most Inventor programs will be fairly easy to port. The Inventor 2.0
- release notes contain detailed information on converting your
- application. Most of your porting job will be fixing minor syntax
- changes (e.g. some length() methods were renamed getLength() for
- consistency with the rest of the toolkit) and fixing #include lines
- for files under /usr/include/Inventor that were moved around (e.g.
- all of the Xt components are now under /usr/include/Inventor/Xt).
-
- Inventor programs that contain a lot of IRIS GL code or that made
- extensive use of Inventor subclassing will be more difficult to port,
- since they will have to be ported to OpenGL and since the internal
- structure of Inventor underwent some major changes.
-
- ------------------------------
-
- Subject: -19- How hard is it to port from Open Inventor 2.0.1 to Open
- Inventor 2.1?
- Date: 09 Jan 1996 00:00:01 PST
-
- Open Inventor 2.1 contains significant performance improvements.
- However, Inventor 2.1 is not binary compatible with previous
- releases, and programs will have to be recompiled. Some programs may
- have to be re-coded to take full advantage of the performance
- improvements. Programs that extend the toolkit, as described in The
- Inventor Toolmaker, are more likely to need re-coding because parts
- of the extender API have changed. For details, please read Open
- Inventor 2.1 Porting and Performance Tips insight book.
-
- ------------------------------
-
- Subject: -20- How can I make my Open Inventor application faster?
- Date: 09 Jan 1996 00:00:01 PST
-
- Read chapter 6 of "Open Inventor 2.1 Porting and Performance Tips"
- insight book. It describes a step by step method to find out your
- performance bottleneck and gives you some tips to optimize them.
-
- ------------------------------
-
- Subject: -21- When I compile my Inventor program, I get an error in
- SoDebugError.h.
- Date: 30 Apr 1994 15:45:00 CDT
-
- You, or something you #include, are #include'ing the IRIS GL header
- file (gl/gl.h). It does: "#define WARNING 2", which conflicts with
- the enum value called "WARNING" in SoDebugError. You cannot mix Open
- Inventor with IRIS GL anyway (because you cannot mix OpenGL with IRIS
- GL), so you should fix your program so it doesn't try to #include
- <gl/gl.h> it should use <GL/gl.h> the OpenGL include file.
-
- ------------------------------
-
- Subject: -22- QUESTIONS ABOUT IRIS INVENTOR
- Date: 06 May 1995 00:00:01 EST
-
- Questions about Iris Inventor.
-
- ------------------------------
-
- Subject: -23- What version of IRIS Inventor runs on which version of
- IRIX?
- Date: 30 Apr 1994 15:45:00 CDT
-
- IRIX IRIS Inventor Version
- --------------------------------
- 3.3.* | (Inventor is not available for IRIX 3.*)
- 4.0.* | 1.0.1
- 5.0.1 | (bad release... do not use)
- 5.1.* | 1.1.2
- 5.2.* | Open Inventor 2.0 (1.1.2 on VGX(T)/GT(X)/PI)
-
- ------------------------------
-
- Subject: -24- Will I be automatically upgraded to Open Inventor if I
- have IRIS Inventor?
- Date: 30 Apr 1994 15:45:00 CDT
-
- Customers with software maintenance contracts that have purchased the
- Inventor 1.0 developer's option will receive the Inventor 2.0
- developer's option when they receive IRIX 5.2.
-
- ------------------------------
-
- Subject: -25- Will my IRIS Inventor programs stop working if I install
- Open Inventor?
- Date: 06 May 1995 00:00:01 EST
-
- No. The Inventor 2.0 run-time system (inventor_eoe) contains a
- complete set of compatibility libraries that will allow existing
- IRIS Inventor applications to continue to work.
-
- ------------------------------
-
- Subject: -26- Can I develop Open and IRIS Inventor programs on the
- same system?
- Date: 06 May 1995 00:00:01 EST
-
- Yes, as long as your system supports OpenGL (Indy, Indigo, Indigo2,
- Crimson, and RealityEngine support OpenGL at this time). First,
- install the 2.0 version of both inventor_dev and inventor_eoe.
- REALLY IMPORTANT: When installing Inventor 2.0, previous Inventor
- versions will AUTOMATICALLY be removed.
-
- To re-install 1.1.2, you will need to use the 1.1.2 CD* to install
- 1.1.2 into a different location (so as not to ruin 2.0). Please note
- that you will have to change the Makefiles of programs that will
- compile and link with 1.1.2 (-I and -l need to point to your safe
- locations of Inventor 1.1.2). To install Inventor 1.1.2 under a
- different root directory than /, so that Inventor 2.0 may be
- installed under /:
-
- # Install 1.1.2 compatibility library from Inventor 2.0 images
- inst -f inventor_eoe (get inventor_eoe.sw.1_1)
- # Create a directory to hold Inventor 1.1.2
- mkdir /usr/myroot
- # Fool inst into thinking you have prerequisites installed
- mkdir -p /usr/myroot/var/inst
- cp /var/inst/{c,dev,c_dev,gl_dev,motif_eoe,inventor_eoe} /usr/myroot/var/inst
- # Install Inventor 1.1.2 under your root directory
- inst -r /usr/myroot -f inventor_dev
-
- To make Inventor 1.1.2 sample programs in this new directory:
-
- ln -s /usr/lib/libInventor.so.1 /usr/myroot/usr/lib/libInventor.so
- cd /usr/myroot/usr/share/src/Inventor/examples/PG1
- # Add to the Makefile, after the line: include /usr/include/make/commondefs
- LC++INCS = -I/usr/myroot/usr/include
- LCINCS = -I/usr/myroot/usr/include
- LLDOPTS = -L/usr/myroot/usr/lib
-
- To re-install Inventor 1.0.1, install the subsystem
- "irix4_inventor_dev", found on the Inventor 2.0 or Inventor 1.1.2
- CDs. This will install the 1.0.1 headers and libraries under
- /usr/irix4. You must change your makefiles to use include and link
- to this new location.
-
- ------------------------------
-
- Subject: -27- Prerequisite error installing Inventor 1.1.2
- Date: 06 May 1995 00:00:01 EST
-
- Many customers are running into an inst installation prerequisite
- error when they try to load inventor_dev 1.1.2 onto their IRIX 5.2
- system. This error is due to a name change in c and dev subsystems
- between IRIX 5.1 and 5.2. The new name is c_dev. The fix is to load
- the *new* inventor_dev 1.1.2 (part # 812-0136-005) made for IRIX 5.2
- that came with the Open Inventor 2.0 Development Package. This
- version is smart enough to do the right thing. Unfortunately, both
- the *old* and *new* inventor_dev 1.1.2 are barely distinguishable
- only by their part number and content. The new inventor_dev 1.1.2 has
- a Copyright of 1992-94 and does not contain inventor_eoe 1.1.2.
-

-
- Subject: -28- Why do I get errors compiling the Inventor sample
- programs?
- Date: 06 May 1995 00:00:01 EST
-
- Inventor 1.0.1 requires C++ version 2.*. If you have C++ version 3.*
- installed on your system, you must specify the -v2 flag to compile
- Inventor programs. If you are using the Makefiles distributed with
- Inventor, you should change the line that looks like:
-
- LC++OPTS = +p -Wf,-XNp10000
-
- to:
-
- LC++OPTS = -v2 +p -Wf,-XNp10000
-
- Inventor 1.1.2 and Inventor 2.0 work with C++ 3.*; you must remove
- the -v2 flag from your Makefiles when you upgrade to those versions
- of Inventor.
-
- If you receive this error when compiling:
-
- "/usr/include/X11/X.h", line 44: error:
- Cursor declared as unsigned short [16] and XID
-
- You should rearrange the order in which you #include your files so
- that the Xt files are included before any file that references the
- IRIS GL include file. For example, be sure to #include
- <Inventor/SoXt.h> before <Inventor/nodes/SoTexture2.h>.
