thesign Immersive visualisation of medical data (IVMD)

immersive visualisation of medical data
One of my 7th semester projects was to build an immersive 3d-cg system. My part was implementing a realtime volume renderer.

Theory:
You have to cut the volume with planar surfaces. Set the mapping coordinates of each plane to map the 3D texture data at the right position. Than take care of the pixel aspect ratio. To render the volume you draw your planes in direction toward the camera and blend them. Therefore it is nessesary to sort the planes your drawing. Rendering the single pictures of the dataset then was just three lines of code because a already had a class for rendering single planes.

At the presentation we had a stereo projection and an Athlon 64 system with a pny quadro FX 1400 graphics accelerator plus a gyro mouse. As far as i can say that is what i think of an immersive system. Thanks to Prof. Dr. Thomas Jung FB4 FHTW-Berlin for his support in the project.

First i did some test renderings to see how HDR works in mental ray.

Bastian is the son of my girlffriend´s sister. He was about to get a e-guitar and an amplifier as a present. My part was to design a symbolic presentcard. I used the REACTOR© engine with the cloth-modifier to create the cable between the amp and the guitar. I used image based lighting to get a good shading.

Amazing oO  GI Photons generate a shadow behind a raytrace plane. This is more training and testcase stuff.the-final_ringtone

My girlfriend is used to have a little elk sitting on top of her monitor.
I thought this one was a good model to practise a little low poly modeling and finishing it all with fur.

thesign DIRECTOR© 3D application “tapes”

4th semester work in development of media systems)

My part was the content creation (all images, videos and 3d models)
the idea scribble

We integrated my old PIONEER CT939mkII Tapedeck into my old pentium2/400 and made it playing tapes which u can choose from the 3D projected screen. The model of the tapes is created by taking 44 pictures of the realscene and work them all together with METACREATION´s CANOMA© to get a vrml model of the scene.
