## Zhu3D: An interactive OpenGL Mathematical Function Viewer

Categories: OpenGL, Softwares Tags: 3d rendering, mathematics, opengl, software, visualization, zhu3d

Zhu3D is an interactive

OpenGL-based mathematical function viewer. You can visualize functions, parametric systems and isosurfaces. The viewer supports special effects like animation, morphing, transparency, textures, fog and motion blur.Zhu3D runs under Linux/Unix, Windows XP-Vista and Mac OS X (the graphical user interface – GUI – uses Qt) and supports different CPU’s as well as different API’s like KDE, Gnome or Motiv. Isosurface calculation currently supports up to 16 CPU-threads.

Ok that sounds good. So let’s try it:

Ooops… c’mon Zhu3D, you don’t recognize an OpenGL system like mine, this is a joke! Doesn’t matter. Let’s see the next:

Ah it’s better. Many samples are provided and you can changer the rendering mode (wireframe, solid, point). And for developers,

**full source code**is packed into the archive. Cool!
