AmbientOcclusionRendering

Order-independent semi-transparent ambient occlusion renderers based on KVS.

Installation

Prerequisite

• KVS

Build

Clone AmbientOcclusionRendering repository from GitHub as follows:

$ git clone https://github.com/vizlab-kobe/AmbientOcclusionRendering.git

Lib

Build AmbientOcclusionRendering library required to compile each application in App and Test.

$ cd AmbientOcclusionRendering
$ cd Lib
$ ./kvsmake.py

If necessary, rebuild the library as follows:

$ ./kvsmake.py rebuild

Test

Some of the test programs are in the Test directory. All of these programs can be built using the kvsmake command in each test program directory (XXX).

$ cd Test
$ cd XXX
$ kvsmake -G
$ kvsmake
$ ./run.sh

Note: Some of test programs require (e.g. Test/SSAOPolygonRendering) a test data, bunny.ply, for executing run.sh. These dataset can be downloaded from KVS.data

App

The App directory contains several application programs. To build and run these application programs, refer to the ReadMe files in each directories.

Class List

The library includes the following classes used in the test programs and application programs. All of classes included in the library are defined in the namespace of AmbientOcclusionRendering.

• AmbientOcclusionRendering::AmbientOcclusionBuffer
  A class that facilitates buffers for screen space ambient occlusion.

• AmbientOcclusionRendering::SSAOPolygonRenderer
  Polygon renderer class with screen space ambient occlusion effect.

• AmbientOcclusionRendering::SSAOStylizedLineRenderer
  Stylized line renderer class with screen space ambient occlusion effect.

• AmbientOcclusionRendering::SSAOStochasticPolygonRenderer
  Order-independent semi-transparent polygon renderer class with screen space ambient occlusion effect.

• AmbientOcclusionRendering::SSAOStochasticStylizedLineRenderer
  Order-independent semi-transparent stylized line renderer class with screen space ambient occlusion effect. A opacity value can be specified for the streamlines.

• AmbientOcclusionRendering::SSAOStochasticTetrahedraRenderer
  Order-independent semi-transparent tetrahedra renderer class with screen space ambient occlusion effect.

• AmbientOcclusionRendering::SSAOStochasticTubeRenderer
  Order-independent semi-transparent tube renderer class with screen space ambient occlusion effect^[1,2]. The opacities can be specified for each vertex of streamlines by using the transfer function.

• AmbientOcclusionRendering::SSAOStochasticUniformGridRenderer
  Order-independent semi-transparent uniform grid renderer class with screen space ambient occlusion effect. The opacities can be specified for each vertex by using the transfer function.
