This 3D grapher plots high quality 2D and 3D graphs. Graphs can be shaded with custom gradual colors along x, y or z axis. In 3D graphs, the lighting is enabled to demonstrate the depth of the surface through shades and shadows. Graphing Calculator 3D is an easy-to-use tool that plots 2D and 3D functions.   Graphing Calculator 3D  Plot high quality 2D and 3D graphs of math equations and coordinates table. This 3D grapher plots high quality 2D and 3D graphs. Graphs can be shaded with custom gradual colors along x, y or z axis. In 3D graphs, the lighting is enabled to demonstrate the depth of the surface through shades and shadows. Our 3D grapher produces quality graphs instantly while you are typing an equation. It also allows real-time rotation, translation and zooming by dragging the mouse. This 3D grapher includes a wide variety of mathematical features and coordinate systems. Cartesian, Polar, Cylindrical and Spherical coordinates are supported for 2D and 3D equations. In addition parametric equations are also supported for all the aforementioned coordinate systems. Loading coordinates from an excel or csv file is a breaze. There are over 40 built-in math functions and constants. If that is not enough you have the ability of defining your own constant, variables and functions. Graphing equations has never been any easier. Simply type a function and observe the graph that is generated instantly after each key stroke.

VIRIAL, INC. provides software and consulting servises to organizations that develop, utilize, and calibrate measurement equipment for radiation thermometry, radiometry, photometry, optical instrumentation, radiation heat transfer, and adjacent areas. Virial, Inc. is the creator of STEEP3 code intended for numerical modeling of radiation parameters of blackbody radiation sources. STEEP3 became de facto standard in calculations of the effective emissivity of blackbodies for calibration laboratories and remote sensing applications. This program is based on the proprietary Monte Calo algorithm and used in such world metrological centers as NIST (USA), NPL (UK), PTB (Germany), NRC (Canada), AIST (Japan), BNM-INM (France), NMI (Netherlands), VNIIOFI (Russia), KRISS (South Korea), BSMI (Taiwan), etc. We have STEEP3 customers in NASA, Space Dynamics Laboratory (Logan, UT), Space Science and Engineering Center (University of Wisconsin-Madison), Dept. Atmospheric, Oceanic and Planetary Physics (University of Oxford, UK), and in the world-leading high-tech companies.  VIRIAL,INC.   - Software and consulting services in areas of optical radiometry, radiation thermometry, and photometry.

Dinosaurs ruled our earth for many, many millions of years. Dinosaurs are thought to be one of the most successful creatures that ever lived in terms of longevity and adaption. Dinosaurs evolved into many different shapes and sizes and had diverse modes of living. The creatures that we normally think of as dinosaurs lived during the Mesozoic Era, from late in the Triassic period (about 225 million years ago) until the end of the Cretaceous (about 65 million years ago) until they were wiped out by a massive comet that hit the earth, along with deteriorating environmental conditions. However, Dinosaurs are still around us today in many forms, and they are the birds who miraculously survived the blast all those millions of years ago.   Dinosaur Den  is an information site about life before and after dinosaurs. Discover the different timelines and how the dinosaurs eventually became wiped out, as well as finding detailed information about dinosaurs themselves from the Triassic, Jurassic and Cretaceous periods.
