Starting the exploration of the Uncanny Valley

Starting the exploration of the Uncanny Valley

After the last half year full of trouble and many events, I’m beginning with my doctoral studies at the University of Stuttgart. It is a great honor for me to be in the research group of doctoral students in the collegue “Digital Media” and be part of a scholarship for three years. Subject of my research is the Uncanny Valley and writing a thesis in the next 3-5 years. Unfortunately, I must reduce my freelance work and academic employment at the Stuttgart Media University of course.

The Common Computer Animation Project

The Common Computer Animation Project

This semester the computer science departement of the Stuttgart Media University starts a common computer animation under the working title “Ascension” – a short movie about a little girl waking up on a flying crystal. 5 bachelor and 2 master students, 1 alumni, 3 external students and 2 acedemic assistants work on this common computer animation project. More about this short: https://blog.hdm-stuttgart.de/cg/category/ca/ascension/

A Photorealistic Earth

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

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”

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 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.

PFlow Script Operator: Particles follow Splines

PFlow Script Operator: Particles follow Splines

Unfortunately there is no Spline-Operator for Particle Flow in 3ds Max and Path-Follow SpaceWarp don’t work with the Force-Operator in PFlow. So we need a particle flow script to control the position of each particle with splines. Here is my solution of this problem.
