slimviewGPU is a research software for displaying SLIM surfaces on programmable GPUs, which includes an implementation of the following paper:
Takashi Kanai, Yutaka Ohtake, Hiroaki Kawata, Kiwamu Kase: ``GPU-based Rendering of Sparse Low-degree IMplicit Surfaces'', 4th International Conference on Computer Graphics and Interactive Techniques in Australasia and the Southeast Asia (GRAPHITE 2006), pp.165-171, 2006.
SLIM (Sparse Low-degree IMplicits) is an implicit surface representation delivering an accurate approximation to a set of points scattered over a smooth surface.
This software was originally developed in 2005-2006 and was renovated in 2021 so as to build successfully by Visual Studio 2019.
This software can run only on Windows. At first, you may try to use binary release (x64), which is available from here. Uncompress zip file and then execute run_pai.x64.bat.
SLIM surface rendering can be done by executing:
% slimviewGPU.exe in.slim2t
SLIM (.slim2t) data can be created by mesh2slim. Please check it out.
On a window, rendering modes can be changed by pressing keys:
- Press "1": Render by billboards, LOD disable (rendered by leaf nodes)
- Press "2": Render by point sprites, LOD disable
- Press "3": Render by billboards, LOD by depth of a slim tree
- Press "4": Render by point sprites, LOD by depth of a slim tree
- Press "5": Render by billboards, LOD by error
- Press "6": Render slim balls, LOD disable
- Press "7": Renderp slim balls, LOD by error
- Press "m": Down LOD levels (finer levels)
- Press "n": Up LOD levels (coaser levels)
The following libraries are required for successfully compiling this software.
Our code uses Cg Toolkit library from nVIDIA. The latest version (Cg 3.1 release) is supported.
When you execute "git clone" with "--recursive" option, you will also get vecmath-cpp and render libraries as a submodule "external/vecmath-cpp" and "external/render":
git clone https://github.com/kanait/slimviewGPU.git --recursive
