C++ wrapper library on top of OSPRay to simplify scientific volume rendering
Provides the following:
- Data/volume abstraction object
- we're focusing on volume rendering
- have one point of contact for data, a Volume object
- Volume objects hold:
- DataFile - underlying representation of the loaded data, metadata, statistics, etc. Can read binary and NetCDF files
- TransferFunction - container for color and opacity maps, attenuation
- Camera abstraction
- easier movement of camera
- direct placement of camera with one function,
setPosition()
- Renderer abstraction
- can directly create images (PPM or PNG)
- can save to given buffer
- can rendering volumes or isosurfaces
- JSON-based config file
- communicate with web applications, e.g. Enchiladas/Tapestry
Each PBNJ object (apart from the Renderer at the moment) is designed to be initialized once and reused. This is the base for Enchiladas, as a Volume, Camera, and Renderer can be initialized once. Then a stream of images can be sent to a client.
PBNJ forms the rendering core for the Tapestry project.
The example application simpleVolumeRender demonstrates using PBNJ with a
JSON config file.
Documentation is provided and can be built to HTML using Sphinx
