GDImageProcessing

An application designed to apply different image effects (Bloom, Edge Detection, Invert) to an image using Compute Shaders, UI was created with Nuklear as a research into Compute Shader usage, additional ImGUI version added.

The purpose of this research was to apply compute shaders to image processing. Taking advantage of the ability to define a x, y, z grid and the fact that a texture is x wide and y tall we can simply set glDispatchCompute (textureWidth, textureHeight, 0) that way for each effect we have a compute shader that is handling a specific pixel. Additionally images with the new effects can be saved as TGA files.

As a little bit of practice I decided to redo the application with ImGui, the process was not difficult since I have some experience with ImGUI, I do say I shifted towards liking ImGUI more with this as it was very simple to just redo the same design.
In the next steps I would like to create a tool to help set up GUI elements, normally elements require x and y position and typing them down and building the solution takes too long, having a slider control to check the values in real time would be very useful and not too complicated to implement.
