3D Graphics, Animation, Rendering
3D computer graphics are different from 2D computer graphics in that a three-dimensional representation of geometric data is stored in the computer for the purposes of performing calculations and rendering 2D images.
Rendering is the final process of creating the actual 2D image or animation from the prepared scene. This can be compared to taking a photo or filming the scene after the setup is finished in real life.

MeshLab
MeshLab is an open source portable and extendible system for the processing and editing of unstructured 3D triangular meshes.
The system is aimed to help the processing of the typical not-so-small unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes.
Features :
The system is aimed to help the processing of the typical not-so-small unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes.
Features :
- Interactive selection and deletion of portion of the
mesh. Even for large models.
- Input/output in many
formats:
import:PLY, STL, OFF, OBJ, 3DS, COLLADA, PTX
export:PLY, STL, OFF, OBJ, 3DS, COLLADA, VRML, DXF
- Mesh Cleaning Filters:
- removal of duplicated, unreferenced vertices, null
faces
- removal of small isolated components
- coherent normal unification and flipping
- erasing of non manifold faces
- automatic filling of small holes
- removal of duplicated, unreferenced vertices, null
- Remeshing filters:
- High quality edge collapse simplfication
- Surface reconstruction from points (a ball pivoting variant)
- Subdivision surfaces (loop and butterfly)
- Smoothing and fairing filters
- High quality edge collapse simplfication
- Various
>Colorization/inspection filters
- Gaussian and mean curvature
- Border edges
- Non two-manifold edges
- Self intersecting faces
- Gaussian and mean curvature
- OpenGL Shader based rendering (write your own
shader!) compatible with Typhoon Lab's Shader Designer
- Large rendering (up to 16k x 16k) for high quality
printing
- The history of the all performed cleaning/editing
actions can be re-played on different meshes or saved and for archival
purposes.
- Extendible plugins based architecture, writing new
mesh processing functions, colorization filters and support for different file
formats is quite easy! Look at href="http://meshlab.sourceforge.net/filter.html"
