Free renderer software for linux

Pixie is a RenderMan like photorealistic renderer. It is being developed in the hope that it will be useful for graphics research and for people who can not afford a commercial renderer.
Pixie Renderer project is an open source project licensed under Gnu Public License (GPL).
Pixie is an open source project. None of the people contributing to Pixie is making any money out of it and were not asking for money. We need your feedback to keep this project alive. Use Pixie, submit bug reports, pictures you rendered with Pixie or just your good wishes.
One of the biggest considerations in Pixies development is the modularity. If youre interested in developing additional features / improving current features, improving the web site, optimizing Pixie, please let us know.
Main features:
- All RenderMan 3.2 primitives
- Quadrics: Sphere, Disk, Cone, Paraboloid, Hyperboloid, Cylinder, Toroid
- Parametrics: Bilinear/Bicubic patches, NURBS
- Subdivision Surfaces including crease/hole/interpolateboundary tags
- Points
- Curves
- Convex / Concave polygons with or without holes and their meshes
- Object instancing / delayed primitives
- Displacements
- Programmable shading (RenderMan Shading Language)
- High quality texture/shadow/environment mapping
- High dynamic range input/output
- Raytracing
- Motion blur
- Depth of field
- Reyes style rendering (very fast)
- Occlusion culling
- Network parallel rendering
- DSO shaders
- Global illumination
- Photon mapping
- Irradiance caching
- Automatically raytraced smooth reflections / shadows
Enhancements:
- 64Bit clean codebase. The Pixie source should compile cleanly on 64Bit platforms. Please let us know if you have any issues with this. Note: youll need libtiff (and X11 on linux / OSX) to be compiled in 64Bit mode too.
- Fixed issues with dissapearing subdiv geometry when raytracing
- Fixed issues with speckled irradiance / occlusion data when using the "R" mode
- Reduced raytrace memory overhead
- Support for vector/color/point/normal subscripting shorthand in SL v[n] = x => setcomp(v,n,x) x = v[n] => x = comp(v,n)

GTK-perl renderer for Data::TreeDumper.

This widget is the gui equivalent of Data::TreeDumper; it will display a perl data structure in a TreeView, allowing you to fold and unfold child data structures and get a quick feel for whats where. Right-clicking anywhere in the view brings up a context menu, from which the user can choose to expand or collapse all items.

RenderMan is a RenderMan binding as a Perl 5.6 module.

SYNOPSIS

use RenderMan;

This RenderMan module implements a Perl 5.6 binding for the BMRT client library (libribout). It fully supports the client library. Therefore, this module has the following limitations: Error Handling callbacks are not implemented, Filter function callbacks are not implemented, and the TransformPoints function does nothing. Also, Blobby is not yet supported by BMRT 2.5.0.8.

The full RenderMan specification is way beyond the scope of this man page. Please refer to the documents below for more information about RenderMan. The Perl binding is identical to the C binding except a few minor points: All "parameterlist"s are passed as a reference to a hash (i.e. %params).

Anywhere that a functions arguments can be terminated by RI_NULL, you can simply choose to not include that RI_NULL argument, which is incredibly nice.
All array, matrix, and basis types are single-dimension arrays of doubles in this Perl binding. The order for 2-dimension types is first-row followed by second-row, etc.

You will typically want to run your RenderMan Perl script and pipe the results into any RenderMan-compliant renderer, such as "rgl", "rendribv", or "rendrib", which all come with the excellent BMRT backage by Larry Gritz.

If using the WinNT version of BMRT, you can specify a filename, "rgl" or "rendrib" as the argument to Begin(); and the output will be sent to a file or automatically piped to "rgl" or "rendrib" since the piping mechanism (and general functionality) of WinNTs command line parser is, uh, limited.

VTKRendering is a Perl interface to VTKRendering library.

FreeType 1 is a portable and highly efficient TrueType rendering engine, that is now successfully used to bring TrueType support to a very large variety of platforms and environments, be they font servers, graphics libraries or embedded systems.
FreeType 1 is a clean-room implementation that is not derived from the original TrueType engine developed by Apple and Microsoft. It has been created with the sole help of the published TrueType specifications, which to our great surprise (and pain) turned out to be extremely poor and misleading in critical areas. Much hard work has been undertaken to solve ambiguities. The end result is a portable and fast renderer.
Note that FreeType 1 is a library. It is not a font server for your favorite platform, even though it was designed to be used in many of them. Note also that it is not a complete text-rendering library. Its purpose is simply to open and manage font files, as well as load, hint and render individual glyphs efficiently. You can also see it as a "TrueType driver" for a higher-level library, though rendering text with it is easy, as demonstrated by the test programs.
Its quality matches these of Windows and the Macintosh, while its memory foot-print and code size (between 48 and 55 kByte of Intel code) remain modest. A thing that cannot be said for most other commercial engines available.
Main features:
- Supports TrueType files (TTF) and collections (TTC). Doesnt support GX or OpenType fonts, but these can be opened and used as normal TTF files by the library. (With the exception of OTF OpenType fonts which really embed a Type 1 font file within a TrueType storage).
- Modular design: Memory and I/O operations can be very easily tailored to your own platform/system (the standard release comes with ANSI libc support).
- Font smoothing, a.k.a. gray-scaling. Just like Win95, the renderer only smoothes the parts of a glyph which need it (i.e., diagonals and curves).
- Support for all character mappings defined in the TrueType specification. The client application can select whichever pleases it.
- A full-featured and efficient TrueType bytecode interpreter. The engine is able to produce excellent output at small point sizes. This component has been extremely difficult to get right, due to the ambiguous and misleadings TrueType specifications. However, we now match Windows and Mac qualities.
- Written in portable ANSI C (and Pascal, for older FreeType 1 versions). Should compile well on all kinds of systems (tested on 16, 32 and 64 bits processors). With full source code available.
- Open Source License. FreeType can be included in all kinds of commercial systems and software.
- Provides test programs to "show-off" the library, runnable on the following platforms: Dos, Unix, OS/2, Win95, and Amiga. Any porters for other systems are welcome and should contact the developers team.
- Support for extensions. These are separately linkable units which can be used to enhance the engines functionalities without recompiling it. They can be written to access additional TrueType tables, or even GX and/or OpenType ones (the latter is already available).
- Kerning support: The TrueType kerning data is available through one of the standard extensions that comes in this release. However, it is up to the application to "interpret" the data, as many different `formats are supported.
- Support for vertical metrics. The engine is able to provide client applications with vertical glyph metrics if they are found in font files (usually in CJKV fonts). If not present, it synthetizes metrics from the horizontal values, ascender, and descender metrics. This means that it is possible to render vertical text correctly.
- Standard extensions are provided to access and load the glyph names in the Postscript table.

Flying Saucer project is a pure Java XML/CSS 2 renderer whose aim is to provide spec-compliant CSS 2.1 rendering for any well-formed XML document.
The current codebase can render to Java2D-based canvases and to PDF via the iText library, and covers a great deal of the CSS 2.1 specification.
There are demos for rendering XHTML, rendering within Swing applications, and rendering to PDF. Direct rendering from DocBook or other XML formats is possible, provided the appropriate CSS is available.
Main features:
- Vertical margin collapsing; CSS 2.1 specification
- Z-index property and stacking contexts; CSS 2.1 specification
- Vertical-align: top/bottom; CSS 2.1 specification
- PDF rendering via the iText library; support for PDF bookmarks, pagination and breaks, and more
- Pagination support, automatic and explicit: CSS 2.1 specification
- Rewritten "float" implementation
- Improved list marker positioning
Enhancements:
- This release includes comprehensive table support, faster rendering, bugfixes, better image generation, near-complete compliance with the CSS 2.1 specification, including lots of improvements like better forms support, CSS counters, cursor property support, compliant font property handling, and so on.
- Theres even a completely new, fast, and compliant CSS 2.1 parser built-in.
