XTrackCAD is a open-source, free, CAD program for designing model railroad layouts. You can easily create layout of any scale or size. Libraries for many brands, scales and gauges of track and turnouts/points and model structures are included. Adding new components is easy with the built-in editor. It runs on Windows, Mac and Linux,

Luminance HDR is a complete suite for HDR imaging workflow. It provides a wide range of functionalities, during both the fusion stage and the tonemapping stage. Its graphical user interface, based on Qt5, runs on a variety of platforms, such as Microsoft Windows, Mac OS X 10.9 and later and several Unix flavors (Linux, FreeBSD and others). Input images can be supplied in multiple formats, from JPEG to RAW files. In the same way, output can be saved in many different formats as well, from JPEG to TIFF (both 8 bit and 16 bit per channel), enabling all the power of your post processing tools.

GLE is a graphics scripting language designed for creating publication quality graphs, plots, diagrams, figures, and slides. Text can be formatted with LaTeX/TeX markup. Its output formats include EPS, PS, PDF, JPEG, and PNG. GLE can operate as either a command line or GUI application.

FractalNow provides users with tools to generate pictures of various types of fractals quickly and easily. It is made of both a command line tool, FractalNow, and a graphical tool, QFractalNow. The graphical tool, based on Qt library, allows users to explore fractals intuitively and generate pictures. Both tools are entirely multi-threaded and implement advanced algorithms and heuristics that make computation very fast compared to most existing free fractal generators.

The Open-Source PyMOL repository has been moved to github: https://github.com/schrodinger/pymol-open-source We still use the pymol-users mailing list here on sourceforge. Please subscribe for community support: https://pymol.org/maillist (Note: SourceForge email newsletter and special offers are optional and can be unchecked) The PyMOL community wiki has its own home: https://pymolwiki.org/

Teem is a set of C libraries for manipulation, measurement, and visualization of structured scientific data. Includes N-dimensional image I/O and processing, volume rendering, diffusion tensor processing, and more. Latest code via git clone http://git.code.sf.net/p/teem/teem.git .

UPDATE: Chromium is no longer updated or maintained. The project is frozen. Chromium is a flexible framework for scalable real-time rendering on clusters of workstations, derived from the Stanford WireGL project code base.

Motion Blur is a free, professional program to simulate various visual effects like blur, judder or tearing that accompany a motion picture. This gives you a preview of how a real motion picture would look like when filmed with the custom parameters.

A library and reference application for viewing and analysing raster and vector geospatial data.

OpenGLEAN: A GLUT family member gone lean.

TerraVision is a real-time multi-threaded 3D terrain visualization system. It can browse massive terrain and other data sets that are streamed over the Web. It also supports overlaying rich 3D models on the terrain to represent buildings, icons, etc.

Here is a c_version of Thomas Bleeker's pnglib 1.0, a free graphy library. His site is https://www.madwizard.org/programming/projects/pnglib Thomas's original code is x86-asm. She(the code) can read and display PNG images in programs, and link without Zlib. With the author's permission, Leisure bamboo translate her to c. So she can be compile by turbo c 2.0, borland c 4.5, visual c 6.0, keil c51 7.5, or others. Some(not all) plainform where she can run, as below: 1)dosbox, see about her in sample.tc2. dpmi.bc4; 2)window, see about her in sample.bc4, dpmi.bc4, sample.vc6; 3)c51's uv2 simulator, see about her in sample.uv2; 4)arm singlechip, that is cino f780 barcode scanner. She can decompress apng(Animated PNG) now, There are some demo file 01.png, 04.png ... 32.png in root folder. She is small(12k for vc6, 32bit code; 21k for bc4, 32bit code; 27k for tc2, 16bit code) and beautiful.

Package for high-quality dynamic PDF documents/charts in real-time & high volumes from any data source. EPS and bitmap formats also supported. Ideal for automated reporting needs. See http://www.reportlab.org/downloads.html.

Viewstl is an open source way to view Stereo Lithography Files as shaded on-screen images. Ascii STL files and dynamic rotation, scaling, and panning are currently supported. Written in C using OpenGL, GLU and GLUT.

The Embedded Systems 3D Game Software Development Kit, short ES 3D Game SDK, is an Open Source 3D Game Engine / SDK for embedded devices based upon OpenGL ES.

The OpenCMISS-Zinc Library (opencmiss.org/zinc), or Zinc, is a software library for building interactive graphical modelling and visualisation applications. Models are represented in Zinc as mathematical fields defined over domains, including finite elements with support for high-order basis functions, complex parameter mappings and time variation, and image-based fields. Further fields can be defined by mathematical expressions and algorithms on existing fields, including image processing filters. Zinc model data structures are dynamic, supporting interactive applications which programmatically create, destroy and modify parts of models.

PyPotrace is a Python programming language binding for Peter Selinger's Potrace raster to vector conversion algorithm. No separate Potrace library or application required!

The Scientific Visualization Artist Tools (SVAT) include converters from the Visualization Toolkit (VTK) to RenderMan Interface Bytestream (RIB) (ASCII and binary files supported), Blender to RenderMan, compilable RenderMan shaders and other utilities.

Varkon is a very powerful parametric 2D/3D CAD, modeling and application development tool for engineering, design, architecture, etc. It does 2D drafting, 2D and 3D modeling, sculptured surface modeling, and even animations. See our website for details.

Use map data to plan hikes or explore new areas. Includes 3D maps of terrain rendered in real-time; trace trails across the terrain and get height verses distance profiles; tile together adjacent maps to create seamless map areas. Reads USGS SDTS files.
