README.TXT File README file for Real 3D V2 for Windows - Demo version Release 2.4 (C) Copyright Realsoft Finland, 1994 This document contains release notes for the Real 3D V2 for Windows Demo version release 2.4. About This Demo version ----------------------- This Demo version is for demonstration purposes only. It may not be used for commercial purposes. Rendering to a file and object data saving have been disabled in this demo version. It is though possible to render to a View window and load in the example projects and objects provided with this demo package. This version of Real 3D can not be run under the Windows NT operating system. Example projects included in the package ---------------------------------------- The projects directory contains example animations which can be previewed just by clicking the 'Preview' button. The default resolution for most animations is 320x200 and rendering time was measured by using DEC/ALPHA AXP150 PC with 32 megs of ram. - Abys: This animation demonstrates how to create waving sea by applying morphing to a bump map texture and a water creature by applying morphing to a B-Spline shape representing the creature. Note that the creature has 'Not-reflected' attribute set in order to speed up rendering. This attribute causes the transparent water creature not be reflected from other objects (from sea in this case). Average rendering time 1 min/frame. - Firew1.prj: This demonstrates how to use CREATION and RPL method to create particles with random velocity. RPL method contains simple formula which modifies the velocity of sample objects for creation method while the whole system is moved along a path. One directed force field is used to apply gravity over created particles. - Firew2.prj, firew3.prj, ...: These projects are different variatons from the firew1.prj. The basic idea is the same but formulas are different. - Ballbear: This is not an animation, so don't try to 'preview' it. The scene consists of three ballbrearings created by using Real 3D Boolean Operations and sphere, cylinder, hyperboloid primitives. Rectangles were used for cutting material away from ballbrearings in order to reveal their inner structures. - Bbanim: This animation demonstrates how to create a complete ballbearing by using Boolean operations. Rendering time when using 'Lampless' ray-tracing mode 30 sec/frame. - Collide: Demonstrates the collision detection feature. A glass cube spins about an axis due to collisions between the axis and the hole of the cube. The total rendering time per frame consists of the actual rendering time (1 min/frame) + the time required for detecting collisions (8 sec/frame). - Cycle3: Simple inverse kinematics example. Hands and legs of the girl were animated by using inversed kinematics while camera flies around the girl. Average rendering time 1 min/frame. - Dice: Collision detection example. Dice were created by using boolean operations. Rendering time when using shadowless ray tracing about 1 min and 15 sec/frame. - Dynamite: This is a particle system example where creation methods create particles with random velocity and a directed force field is used for simulating gravity. Average rendering time 10 sec/frame. - Engine: A car engine created by using Boolean Operations and quadrics such as cylinders, spheres, hyperboloids and cones. Rendering time 30 sec/frame. - Fly: Butterfly and flower. The wings have been animated by using morphing and the entire butter-fly follows a spline path. The flower has been animated by using morphing. Rendering time about 10 sec/frame when using shadowless ray traycing mode. - Girl: This is not an animation. Click the button '5 3 1 MENU' in order to render all windows. The purpose of this example is to demonstrate 'smoothness' of Real 3D B-Splines as well as modelling capabilities. Rendering time less than 30 sec per window. - Glass: This is not an animation but demonstrates the quality of Real 3D glass objects. - Glass2: Animation where glass spoon follows a path like a snake and a glass vase is morphed. Average rendering time 14 min/frame - Glass3: Another glass example. This is actually pretty nice with 24 bit. - Matmorph: This animation demonstrates how to create a water turbulence by moving a waving bump map along a B-Spline object. Rendering time 25 sec/frame - Morphing: Animation where two spheres are morphed to form a head of a human being. The texture is bound to the parameter space of the B-Spline by using 'B-Spline' mapping. When the head is stretched, the texture is stretched as well. Rendering time 1 min/frame. - Alley: Bowling alley simulation described in the manual. Rendering time 1 min/frame. - Pixtool: 3D fonts created from particles by using pixel-tool. At the end of the animation, the logo is exploded by using radial force method. The scene consists of 1700 spheres. Rendering time 15 sec/frame. - Power: This demonstrates Fonts created by using the True-type outline font generator. Rendering time 45 sec/frame. - Shark: This demonstrates how to create wriggling snakes, swimming fishes, etc. by subdividing B-Spline objects to subgroups and animating them using the direction method. Rendering time 10 sec/frame. - Stairs2: Simulation where three bowling pins falls down the stairs. Rendering time 2 min/frame. - Turbul: Particle system example which consists of one creation method and one force field. Rendering time 30 sec/frame. - Walker: Walking girl. This girl was animated by using the SWEEP method and hierarchical construction. One sweep method rotates the shin-bone about the knee and another sweep method rotates the entire leg about the hip-bone. Rendering time 30 sec/frame. Installing Real 3D V2 for Windows --------------------------------- Real 3D needs services provided by Microsoft Win32s. Therefore you must first install Win32s if not already installed or if your installed version is not the latest (version 1.1). In order to install Win32s, you need Microsoft Windows for Workgroups or Microsoft Windows 3.1 running in enhanced mode with paging enabled. If you install Win32s on Windows 3.1, it is necessary to run the MS-DOS Share utility before starting Windows. Add SHARE.EXE to your AUTOEXEC.BAT file. SHARE.EXE is not required if you are using Windows for Workgroups. It is recommended that your CONFIG.SYS file set number of files to at least 30. Set files=30 in CONFIG.SYS if there is no files command line or if it specifies less than 30 files. If your system uses any other Windows shell than Program Manager (PROGMAN.EXE) it must be disabled while installing Win32S and Real 3D. Such Windows shells are, among others, Norton Desktop for Windows and DashBoard. To disable a Windows shell change the line starting with shell= in the [boot] section of the SYSTEM.INI file to shell=progman.exe Installing Microsoft Win32S 1. Run SHARE.EXE before starting Windows, NOT in a Windows DOS shell 2. Start Windows 3. Insert disk 1, containing installation files of Win32S in drive A: or B: 4. Choose Run from the File menu of the Program Manager 5. Type A:SETUP or B:SETUP 6. Follow the instructions Verifying Win32s Installation In addition to installing the Win32s system components, the Win32s Setup program optionally installs the Win32 card game FreeCell. After installing Win32s, you can run FreeCell to verify that Win32s is installed correctly. FreeCell is located in the Program Manager group Win32 Applications, which the Win32s Setup program creates. If the FreeCell game does not run, you may have sotfware or hardware that is not compatible with Win32s. You can contact your local Microsoft subsidiary or sales office if you need help with Win32s. Install Real 3D only when you have made sure that the Win32s subsystem is functioning properly. Installing Real 3D 1. Insert disk labeled 2 in drive A: or B: 2. Choose Run from the File menu of the Program Manager 3. Type A:SETUP or B:SETUP 4. Follow the instructions Disabling Win32s If you must disable Win32s or wish to do a clean reinstallation of Win32s, take the following actions: Remove the Win32s VxD line from Windows SYSTEM.INI file in the [Enh386] section: device=c:\windows\system\win32s\w32s.386 Delete the W32sYS.DLL and the WIN32s16.DLL files from the \system directory and all files in the \system\win32s subdirectory ( is the Windows installation directory such as c:\windows). Restart Windows Note that Real 3D can not be used if Win32 is disabled or has not been installed properly. REALDEMO.EXE Command line options --------------------------------- The command line contains the names of the project files to be loaded. The command line is entered in the program item properties. To change the command line, activate the Real 3D icon, choose Properties from the File menu of the Program Manager, then Enter the command line. If no project files are specified in the command line, Real 3D reads the default project file 'startup.r3d' from the working directory (also defined in program item properties).
