Visualising simulation data
Take spreadsheed data and import it into geometry nodes like csgQuadMesh.
Use material overrides and shaders to highlight certain aspects of datasets.

2D image processing
A lot of effects like overlays, glow or blur work on the final 2D image
created by the renderer. The tsg image processor is part of tinySG's
utility library and comes as an independent framework. Use the image
processor to increase the atmosphere of clean, math-dry renderings or
enrich the image with additional information.

Realistic interaction of models with environments
Rendering a model with reflections, mirroring an environment and casting shadows
increases the realism of a scene dramatically.
tinySG rendered some nice images, combining it's multi-texturing texturing and
shader capabilities. See more images like the one to the left
here.

Volumetric dataset rendering
The mummy dataset was created by the British Museum. It is a CT scan
of an egyptian priest living about 800BC, the Nesperennub mummy.
The image to the left was generated using csgEdits volume property
editor to setup transfer functions for the absortion voxel field.

CAD data visualisation
The Aston Martin DB9 CAD data set has been worked off with a bunch of
new features of csgEdit, like geometry re-meshing, state sorting,
orientation flipping, normal recalculation, tree optimisation and
a dozen of other functions.

Interactive, large datasets
The model of the international space station has about 1.6M
triangles. It is rendered at 10Hz, including the earth with about 70MB of
texture, using a GLSL shader for atmospheric effects.

Soft Shadows on the Utah teapot
The image shows a ground soft shadow, calculated for the Utah teapot
in csgEdit. tinySG handles soft shadows as scene properties. They may be baked
into a texture or based on a colored grid of vertices.

Water Simulation using GLSL
The water animation and lighting shader has been the first
shader programs written for csg's GLSL subsystem. It animates a mesh
using four superimposing sine waves and calculates an environment
reflection in the pixel shader.
Initial development has been done using nVidia's cg, running on a
Silicon Graphics Prism.

3dtv
3dtv is a pretty old experimental code based on csg. It utilises multiple graphics
cards for image feature detection and may calculate a virtual model for tv soccer
broadcasts, almost in realtime.
The image shows a life video from the world championship 2006, augmented with
detected features.

csgPresenter
csgPresenter is an application running 3D-enriched presentations
and slide shows. Build on top of csg, it is capable of driving
blended, multi-projector systems with multiple graphic pipes.
It can embedd inventor datasets in the presentation,
or display stereoscopic images, like taken from NASAs Mars rovers.
| Features: |
multithreaded Qt application, parallel rendering, support
for various image formats, alpha blending |
