Welcome to the EVOLVE Helppage
The applet is based on the core EVOLVE volume rendering algorithm and was tested on SGI workstations and Pentium PCs. Since it is our first prototype implementation, not all features of the C++ version of EVOLVE are included. The following rendering features are currently implemented in Java:
Note that the rendering is performed on your computer ! Therefore you should enable jit (just-in-time) compilation. The rendering perfomance depends on the network bandwidth and the available hardware platform. The rendered image refines progressively and will be updated if ten percent of the volume's energy is transmitted.

273,740 Bytes (1 : 30) |
1,837 Bytes |
vh_ct |
Y |
256 x 256 x 256 |
256,104 Bytes (1 : 65) |
1,925 Bytes |
vh_PCA_Large |
PCA |
256 x 256 x 256 x 3 |
250,410 Bytes (1 : 201) |
1925 Bytes |
| patient_tumor | PCA | 256 x 128 x 256 | 200,766 Bytes (1 : 125) | 2213 Bytes |
All these data sets are projected into wavelet space and coded
according to our coding scheme [Lip97]. This results
in a lossy compression scheme that allows progressive transmission and
rendering.

Rotation:
Click onto the appropriate arrow. A mouseclick into the middle of the navigation area, where the EVOLVE-logo is placed will center the volume. The image updates automatically.
Texture Inspector:
Displays the eight splats, that are used for the image-domain rendering. Positive values are colored red, negative values are displayed in blue.
Control Panel:
Contains controls for rendering parameters:
