LPub3D
LDraw™ editor for LEGO® style digital building instructions.
LPub3D is an Open Source WYSIWYG editing application for creating LEGO® style digital building instructions. LPub3D is developed and maintained by Trevor SANDY. It uses the LDraw™ parts library, the most comprehensive library of digital Open Source LEGO® bricks available (www.ldraw.org/ ) and reads the LDraw LDR and MPD model file formats. LPub3D is available for free under the GNU Public License v3 and runs on Windows, Linux and macOS Operating Systems. LPub3D is also available as a Linux 'no-install', multi-platform AppImage. Portions of LPub3D are based on LPUB© 2007-2009 Kevin Clague, LeoCAD© 2025 Leonardo Zide, LDView© 2025 Travis Cobbs & Peter Bartfai and additional third party components.

mini3d
3D Software Renderer in 700 Lines
The 3D software rendering tutorial, without any performance optimization, mainly shows people how to write a software renderer with a fixed pipeline. Although the main body code is only 700 lines, the sparrow is small and complete. The source code has only one mini3d.c, and a single file implements everything and is easy to read. No third-party library dependencies, no complicated project directories. Standard D3D coordinate model, left-handed system plus WORLD / VIEW / PROJECTION three matrices. Implementing Cropping: Simple CVV Cropping. Up to 1024 x 1024 textures. Use the depth buffer to judge the image before and after. Perspective Texture Mapping and Perspective Color Fill. Accurate polygon edge coverage calculation. The rendering engine has only 700 lines, the modules are clear, and the backbone is prominent. Detailed comments, detailed comments on the main code. -

Software Renderer
A shader-based software renderer written from scratch in C89
This is a shader-based software renderer written from scratch in C89 with minimal dependencies, available for Windows, macOS, and Linux. Pre-built binaries for Windows, macOS, and Linux are available for download from the Releases page. To build the software renderer from source, a C89 compiler and development files for your window system are required. Install Visual Studio with C++ support and run build_win32.bat. If the software renderer is launched without arguments, one of the available scenes will be chosen randomly. To display a specific scene, additional arguments should be supplied. Metallic-roughness workflow. Specular-glossiness workflow. Image-based lighting (IBL). Orbital camera controls. PBR material inspector. Perspective correct interpolation. Depth testing. Alpha testing. Alpha blending. Cubemapped skybox. Skeletal animation. Tangent space normal mapping. -

Rayshade
Rayshade raytracer
now gnu-ized, gcc-4.7.4 or gcc-10.2.0 A raytracer does not require custom code for (shadows, mirrors) like GL: it uses physics to simulate light to make realistic images, leaving one to specify only what is in the scene. (at a cost of speed) Rayshade is a 1990's raytracer, a great one back then (and still useful). Rayshade has an excellent easy to read yet informative User's Guide that other's could not help but copy from. (html of guide is in rayshade-4.0-ftp-and-guide.tar.gz) Rayshade has no GUI but as a text language it's simple and elegant. --- The Utah Raster Toolkit 'liburt' is "optional" (see Files) and needed to see your output and adds alpha texures: see NEWS. (do NOT use URT with Rayshade-Mathematica, it likes raw rgb). export CFLAGS="$CFLAGS -DPOPEN -DUSE_CPP" [ -n "$WITH_URT" ] && { CFLAGS="$CFLAGS -I/usr/local/include -DURT" LDFLAGS="$LDFLAGS -L/usr/local/lib64" LIBS=" /usr/local/lib64/librle.a export LDFLAGS LIBS } sh ./configure -
