Convert C++ function into Shader Language

We have simpliest OpenGL application, which loads a grayscale image, shows it and allows to change brightness, contrast and gamma. We need to add two custom filters to the application. We have the C++ sources for the function (about 40 lines of code), which implements these filters for GDI. You can find this function in attachment (function is called "draw"). We need to convert this function into shader language and add the ability in our application to use these filters. The project goals: 1. Convert the function from C++ into shader language. So we will be able use two filters. 2. Add using these filters into our OpenGL application. 3. Add two scrollbars into our OpenGL application. Dragging these scrollbars should apply new values parameters for the filters 4. After converting function from C++ into shader language image you must ensure, that there is no any artefacts inside the image (there should be no crossing lines inside the image or something like this) Sources for OpenGL application and for original GDI application will be provided for bidders. ## Deliverables The most important to complete this project in a 3 days after start. * * *This broadcast message was sent to all bidders on Wednesday Aug 5, 2009 12:14:13 AM: There is a mistake in function name in the bid request. Function is called "fkernel::play"
