OpenGL Demos

20.12.2009 High Dynamic Range Image Based Lighting using Deferred Shading
hdribldf
This demo shows real time high dynamic range image based lighting using deferred shading.

16.03.2008 Snow and Ice Landscape Rendering
Snow and Ice Landscape Rendering
This new OpenGL demo shows techniques for rendering snow and ice landscapes. It features: Snow and Ice Rendering, Procedural Terrain and Textures, Sparkling Snow, Frozen Water, Weather Effects, Real-Time Terrain Shadows and much more.

31.10.2007 Volumetric Smoke
Volumetric Smoke
This demos shows volumetric smoke using a particle system, a GLSL sky shader and simple atmospheric scattering using GLSL shaders.

20.08.2007 Non-Photorealistic Rendering
NPR
This new demo shows non-photorealistic rendering of 3D-scenes using GLSL shaders. There are three kinds of non-photorealistic rendering in this demo: Cartoon Shading, Pencil Shading and Ink Shading.

27.12.2006 The Garden
garden
This demo shows a few shader effects in a garden scene. Effects included: Depth-Of-Field, Water, Soft Blurred Shadows, An animated Skybox, Grass & Leaf Rendering, Per-Pixel Lighting

17.05.2006 PhysX and Shadows
pns
This demo shows my physics playground together with soft shadow mapping. The AGEIA PhysX SDK (now NVIDIA PhysX) is used for the physics effects. The demo features many rigid bodies and allows you to interact with the scene by throwing boxes or a rag doll. The soft shadow mapping uses the EXT_framebuffer_object extension for render-to-texture operations. A GLSL shader blurs the shadow to produce soft, fuzzy shadows.

02.04.2006 Mandelbrot Viewer
mandelbrot
This new demo shows the rendering of the Mandelbrot set using GLSL shaders and FBOs. It allows the user to change the number of iterations and the visualization of the set. Category: Useless, but nice to watch.

22.01.2006 Relief Mapping
rtm
This demo shows Relief Mapping, a dynamic sky and HDR Rendering. The Relief Mapping shader uses two linear searches and depth correction for correct silhouettes along surface intersections. The sky shader allows you to control the cloud density and the cloud clover. Finally a HDR bloom shader smoothes the scene.

29.05.2005 Glow
glow
This demo shows a glow post processing effect. The demo also features: Per-Pixel Lighting, Stencil Shadows and texture perturbation effects. All shaders are written in the OpenGL Shading language (GLSL), so you need a GLSL compatible graphics card to run this demo.

09.03.2005 Water-Fire-Sky
water
This demo shows the rendering of clean and foggy water, fire and sky. The demo also features y-Axis billboarding and simple collision detection/response. A tutorial about the water effect is included.

15.01.2005 Depth-Blur
water
This demo shows a Depth-Blur effect. Objects which are far away from the viewer appear blurred. This effect also automatically reduces aliasing to a minimum.

08.12.2004 RTT-FX 2
rttfx
This demos shows the following Render-To-Texture Effects: Camera (simple rtt),Water (reflection & refraction),Refraction,Blur,Color inversion, Laplacian Edge Detection,Blur

08.12.2004 Galtons Board
galtonboard
GaltonGL is a simulation of Galton's Board. It's physically not 100% correct, but it works.

30.10.2004 Simple Snake
snake
Simple Snake is a Snake-Remake.

30.10.2004 RTT-FX
rttfx
This demos shows the following Render-To-Texture Effects: Camera (simple rtt),Water (reflection & refraction),Refraction

10.03.2004 Naturise Engine
naturiseengine
Naturise Outdoor 3D Rendering Engine

01.01.2003 Soft stencil Shadows
softshadows
Soft Stencil Shadows Rendering

01.01.2003 Soft stencil Shadows
shadows
Stencil Shadows Rendering

01.01.2003 Refraction Shader
refaction
This Demo simulates refraction. The scene is rendered to a texture and the texture coordinates are then perturbed by a dynamic-generated Perlin Noise texture.

01.01.2003 Vertex Lighting
vertexlight
Per-Vertex-Lighting calculated on the CPU
