A Photorealistic Earth

One of the most complicated shader types in cg are the earth shaders. Although there are only a few 3d spheres with textured surfaces and one sunlight you have to choose unlimited opportunities to design a performant, realistic and detailed scene of the earth, the moon and the sun. There are many different techniques and material properties to design an earth surface model – realistic or abstract. I’ve created a photorealistic earth & moon shader for V-Ray Renderer based on the NASA Blue Marble Earth Maps. You can download this models¬†here.

How to bring your 3d models from 3ds max to the browser

This tutorial shows us a simple method to export 3d meshes from 3ds max to an own Javascript file format. We save a 3d-Mesh including textures and UV mapping from 3ds max using MaxScript and load them into a lightweight WebGL-Engine.

The Making of the “Santa Maria”

In May 2011 I was commissioned by the Film Academy Ludwigsburg and Korion GmbH for a computer game to visualize a high-rez model of an explorer’s ship. The first thing I thought of this was the “Santa Maria” of Christopher Columbus, who reached America in 1492. For a game trailer I’ve rendered a ship and a few additional models for four CG sequences.

The Golden Ratio in 3D human face modeling

The freehand modeling of three-dimensional human faces with an usual 3D-animation software is still a big challenge for many CG Artists. A problem during the modeling process of real, human-like characters is the observance of certain natural proportions.  An important role plays the famous Golden Ratio, which is difficult to be applied in many ways.
