Some of the Cool .Net Projects

Paint .NET

Paint.NET is free image and photo editing software for computers that run Windows. It features an intuitive and innovative user interface with support for layers, unlimited undo, special effects, and a wide variety of useful and powerful tools. An active and growing online community provides friendly help, tutorials, and plugins.

It started development as an undergraduate college senior design project mentored by Microsoft, and is currently being maintained by some of the alumni that originally worked on it. Originally intended as a free replacement for the Microsoft Paint software that comes with Windows, it has grown into a powerful yet simple image and photo editor tool. It has been compared to other digital photo editing software packages such as Adobe Photoshop, Corel Paint Shop Pro, Microsoft Photo Editor, and The GIMP.

Features

• Simple, intuitive, and innovative user interface
  
  • Every feature and user interface element was designed to be immediately intuitive and quickly learnable without assistance. In order to handle multipleimages easily, Paint.NET uses a tabbed document interface. The tabs display a live thumbnail of the image instead of a text description. This makes navigation very simple and fast.
  
  
  
  
  
• Layers
  
  • Usually only found on expensive or complicated professional software, layers form the basis for a rich image composition experience. You may think of them as a stack of transparency slides that, when viewed together at the same time, form one image.
  
  
  
• Frequently Updated
  
  • Updates usually come about every 4 to 8 weeks, and contain new features, performance improvements, and bug fixes. Upgrading to the latest version is very simple, requiring only two clicks of the mouse.
  
  
  
• Special Effects
  
  • Many special effects are included for enhancing and perfecting your images. Everything from blurring, sharpening, red-eye removal, distortion, noise, and embossing are included. Also included is our unique 3D Rotate/Zoom effect that makes it very easy to add perspective and tilting.Adjustments are also included which help you tweak an image's brightness, contrast, hue, saturation, curves, and levels. You can also convert an image to black and white, or sepia-toned.
  
  
  
• Powerful Tools
  
  • Paint.NET includes simple tools for drawing shapes, including an easy-to-use curve tool for drawing splines or Bezier curves. The Gradient tool, new for 3.0, has been cited as an innovative improvement over similar tools provided by other software. The facilities for creating and working with selections is powerful, yet still simple enough to be picked up quickly. Other powerful tools include the Magic Wand for selecting regions of similar color, and the Clone Stamp for copying or erasing portions of an image. There is also a simple text editor, a tool for zooming, and a Recolor tool.
  
  
  
• Unlimited History
  
  • Everybody makes mistakes, and everybody changes their mind. To accommodate this, every action you perform on an image is recorded in the History window and may be undone. Once you've undone an action, you can also redo it. The length of the history is only limited by available disk space.

Unlike most free image editors, Paint.NET supports layers and has an action manager. The pleasant interface creates semi transparent boxes to skill up. Version 3 confirms many old squabble, including an appropriate manager thumb nail for the treatment of multiple image editing, and improved program graphics. Paint.NET is far more sophisticated than the paint and Microsoft are free price, it 'SA must-have for all those pictures to confirm.

ChemPad: A Pedagogical Tool For Exploring Handwritten Organic Molecules

Organic Chemistry is a hard course. Early in their college studies, students who wish to pursue a career in medicine must have a solid understanding of organic chemistry and, perhaps more importantly to the students, a good grade in Organic Chemistry. The difficulty of the material prevents many students from continuing with this career path. One of the major difficulties for students in Organic Chemistry is understanding the three -dimensional nature of molecules.

Students usually have no background in three-dimensional visualization and have great difficulty converting between the two-dimensional drawings used in text books and on classroom black-boards to represent molecules and their three-dimensional structures. Without this understanding, to survive the course, students must memorize a large vocabulary of molecules and rules to fake an understanding of the three dimensional structures. Although this is possible for some, good students and good chemists tend to learn to visualize the molecules in three dimensions and apply a much simpler set of rules to these visualizations.

Using ChemPad consists of drawing a molecule in the Sketch panel and observing the three-dimensional structure in the View panel. Instead of selecting atoms and bonds from toolbars and menus the way a chemist does in professional modelling software, students use the Tablet PC stylus to draw a molecule in digital ink on the tablet that looks very similar to the same drawing they would make on an exam or on paper when talking to another chemist about the molecule. These drawings consist of single-stroke symbols representing atoms, bonds, and special pedagogical functions. For example, a student drawing ethanol would draw two C’s and an O to represent the two carbons and one oxygen in the molecule.

The atoms are then connected with covalent bonds by drawing straight lines between letters. As the atoms and bonds are being drawn, the View panel displays the balls and sticks of the atoms and bonds being recognized and the Sketch panel is incrementally prettifying the user’s input. By tapping the “Interpret” button, the student indicates that the drawing is complete and ChemPad presents the user with a 3D scene showing the ethanol molecule with implicit hydrogens attached and the molecule oriented in the configuration approximated by the user’s drawing.

ChemPad with it 's improved engine construction and capacity to the relative energies of conformation show available to Chem 35 in 2006. The laboratories followed much the same format as in 2005, but was heavier ChemPad - used in reading. Can a molecule quickly sketches and an interactive 3D model was extremely useful to answer "what if" questions of students.

3D Journal

It's the program 3DJournal.To create a 3D image you need 2 images,one from your right eye view and second from your left eye view. How to get them? Load both images to 3DJournal software using buttons located at it’s right side. The images then will be shown in their windows. Press Create 3D image button and the 3D image is created. You can see there color ghosts which allow your eyes with glasses to see the image stereoscopically/3D. You can use not only the buttons but the menu as well.To get a spatial (3D, stereo) effect it's necessary for the observer to see different images with different eyes. For this it's necessary to use a special projection system or a 3D glasses.

3D animations and 3D movies

• To create 3D animations and 3D movies, Save left images of your animation/movie to one folder. Save right images of your animation/movie to another folder. The pictures should be numbered, for example this way: Left001.gif, Left002.gif, Left003.gif and Right001.gif, Right002.gif, Right003.gif etc.
  
  
• Load the first left image and the first right image to 3DJournal software and make all things as usually. Then save it.
  
  
• Press the Extra button. You can see filled in image names and you can fill in only the number of 3D images to create. Press Start processing button. All the images will be processed in the same way as the first one,including rotation, shifting and cropping before saving.
  
  
• Using created 3D images you can create a 3D animation or a 3D movie.

Features

• Set color coding of the image. The standard coding is anaglyph for red/cyan glasses, but you can set the coding for example for blue/yellow glasses as well.
  
  
• Set the quality of saved jpg image. We recommend to use higher quality which allow to get a good 3D effect.
  
  
• Create more 3D images at once – for example for creating an animation or movie.
  
  
• Save settings/properties. This function saves for example the rotation, shift of the images, color coding, jpg quality, cropping of saved image for animations etc. So you can return to your image editing anytime and use the older parameters for example for preparing frames for your 3D movie.
