4D Interactive Models, also known as 4DIMs has previously been C Tech’s preeminent 3D publishing standard. It has been supplanted by the C Tech 3D Scene Viewer and EVS Presentations
Each frame can represent different content and/or views, providing the model creator the greatest scientific and artistic freedom in the publishing process. They are far faster and more feature rich than 3D PDFs or web-based models. 4DIMs accommodate time domain data and large models much better than any other alternative.
4DIM files require installation of C Tech’s free Standalone 4DIM Player, which is unlicensed and may be freely redistributed to clients and the public. The installer is 60 MB.
This 4DIM model of a coastal facility with chlorinated hydrocarbon contamination in the groundwater is located in the Pacific Northwest. This model is using photographic textures on the straphigraphic layers.
This volumetrics study of a railyard site investigates 8 different regions, each having 3 geologic layers and 7 contaminant reporting levels. The result is a 4DIM file with 168 frames, each showing detailed volumes and masses of total hydrocarbons.
The same railyard site is show above using a visualization technique called arrays-of-slices. The slices are colored and their opacity is adjusted based on concentration level. This 4DIM has only one frame.
The same railyard site using arrays-of-slices is presented with 12 frames which increasingly explodes the three layers apart. Because of the high resolution of this grid and the rendering technique, this 4DIM file becomes quite large.
This model shows three nested plumes at different plume levels. There are three frames in this 4DIM for three different analytes: Benzene; Toluene and Xylene.
Sandia National Laboratories has long used C Tech’s software to model and analyze the salt domes and solution mined caverns which are used to store the United State’s Strategic Petroleum Reserves. This 4DIM has 10 frames which investigates 5 different caverns and their proximity to the dome wall.
This 40 frame 4DIM file investigates 4 different MIP analytes: Conductivity, FID, PID and XSD over a wide range of subsetting levels to thoroughly understand the distribution of levels throughout the data collection region.
