OpenGL Demos

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

16.03.2008	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
	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
	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
	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

PhysX and Shadows

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
	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
	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
	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
	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 of Field
	This demo shows a Depthof Field 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
	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
	GaltonGL is a simulation of Galton’s Board. It’s physically not 100% correct, but it works.

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

10.03.2004	Naturise Engine
	Naturise Outdoor 3D Rendering Engine .

01.01.2003	Soft stencil Shadows
	Soft Stencil Shadows Rendering and Hard Stencil Shadows Rendering ..

01.01.2003	Refraction Shader
	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.
