Open Source C++ 3D Modeling Software

The Point Cloud Library (PCL) is a standalone, large scale, open project for 2D/3D image and point cloud processing. PCL is released under the terms of the BSD license, and thus free for commercial and research use. Whether you’ve just discovered PCL or you’re a long time veteran, this page contains links to a set of resources that will help consolidate your knowledge on PCL and 3D processing. An additional Wiki resource for developers is available too. To simplify both usage and development, we split PCL into a series of modular libraries. PCL is cross-platform, and has been successfully compiled and deployed on Linux, MacOS, Windows, and Android. To simplify development, PCL is split into a series of smaller code libraries, that can be compiled separately. This modularity is important for distributing PCL on platforms with reduced computational or size constraints.

GlslViewer is a flexible console-based OpenGL Sandbox to display 2D/3D GLSL shaders without the need of a UI. You can definitely make your own UI or wrapper using the Python Module (include) or any other tool that communicates back/forth with the GPS viewer through the standard POSIX console In/Out or OSC. Default vert/frag shaders for 2D shader and 3D material shaders with PBR lighting model. Hot reload of files on changes. One default light and one default camera. Interactive commands thought POSIX console IN/OUT or OSC. Different debug modes (histogram, textures, buffers, bounding box, etc). Shadow maps. Headless rendering. Fullscreen and screensaver mode. HoloPlay rendering on LookingGlass Display. Image export. PNG sequence export. WASM crosscompiling. Automatically generated set of defines based on the platform, buffer, render pass, geometry attributes and materials properties. Passing custom uniforms (float, int, vec2, vec3 and vec4) through console IN or OSC.

The data is stored in an own in-memory data-format, which can be easily processed. www.open3mod.com/ is a 3D model viewer and exporter based on Assimp that is also Open Source.

ImatiSTL is a C++ library for applications that need to finely post-process raw polygon meshes represented by STL files. It is particularly useful in 3D printing scenarios: the repairing functions provided by ImatiSTL bridge the gap between printable meshes and real-world meshes with diverse potential defects and flaws (e.g. degenerate triangles, self-intersections, surface holes, ...). ImatiSTL provides both functions for local mesh repairing and methods for global remeshing. Local repairing is useful when the available data must remain exactly as it is in the input STL file, whereas global remeshing may fix even highly corrupted meshes at the cost of a small distortion in the resulting fixed mesh.

IVCon-TL can read and write a variety of 3D graphics file formats, converting from one to the other. Supported formats include 3DS, ASE, BYU, DXF, GMOD, HRC, IV, OBJ, OFF, POV, SMF, STL/STLA/STLB, TEC, TRI/TRIA/TRIB, UCD, VLA, WRL/VRML, XGL and more.

The Mangrove Topological Data Structure (Mangrove TDS) Library is a C++ template tool for the fast prototyping of topological data structures under the same API: - generic representation of any topological data structure, i.e., mangrove; - extensible through dynamic plugins at run-time; - agnostic wrt the representation in use; - any representation is supported without restrictions; - dimension-independent and multi-platform; - efficient representations of non-manifolds; - only one common API and no wrappers; - implicit representation of cells, not directly encoded, i.e., ghost references.

The project was born when I wanted to write a 3D modeling + rendering engine in C++. I wanted to create an easily expandable tool for the GUI, that will automatically know how to display the various objects for editing. The goal was to make each object "know" how it should be displayed and changed, so that a simple GUI tool can display complex objects, and new objects can be created without having to spend time creating the "widgets" for them. The basic requirements was: - The "GuiObjects" don't know which graphical toolkit (e.g. gtk) will be used to display them. - The objects can be displayed without knowledge of what exactly they are. - save/load/undo/etc. will be taken care of automatically. In addition, because this is a project I started to train in C++: - there will be no dynamic casting! (I hate them) - using c++0x (I want to learn - sorry!) I'm still working on implementing a ray tracing program with it, and maybe other tools as well

This program will be a 3d Editor for Erwin Coumans's 1996 3D Engine Demo (http://coockie.com), in hopes that it can be used to create worlds more effectively, and give anyone a basic knowledge of creating a 3d editor.

ThinksCollabs is a research collaborative project. It aims at allowing researchers from different areas to work together. It consists of different projects concerning collaborative and interactive 3D modeling, bird flight simulation and city modeling.

Curv is a programming language for creating art using mathematics. It's a 2D and 3D geometric modelling tool that supports full colour, animation and 3D printing. Curv is a simple, powerful, dynamically typed, pure functional programming language. Curv is easy to use for beginners. It has a standard library of predefined geometric shapes, plus operators for transforming and combining shapes. These can be plugged together like Lego to make 2D and 3D models. Coloured shapes are represented using Function Representation (F-Rep). They can be infinitely detailed, infinitely large, and any shape or colour pattern that can be described using mathematics can be represented exactly. Curv exposes the full power of F-Rep programming to experts. The standard geometry library is written entirely in Curv. Many of the demos seen on shadertoy.com can be reproduced in Curv, using shorter, simpler programs. Experts can package techniques used on shadertoy as high-level operations for use by beginners.
