This library doesn't tackle all functionality related to terminal emulation, but only the area of visual representation. \n\nDemo on Youtube:\n\n[![Watch the video](/doc/img/cterm_youtube.png)](https://www.youtube.com/watch?v=SO9MrM9zTuk)\n\n## Dependencies\n\n- The only dependency is the [LWJGL library](https://www.lwjgl.org/). These files need to be linked with the project:\n    - **Windows:** lwjgl.jar, lwjgl-natives-windows.jar, lwjgl-glfw.jar, lwjgl-glfw-natives-windows.jar, lwjgl-opengl.jar, lwjgl-opengl-natives-windows.jar\n    - **Linux:** lwjgl.jar, lwjgl-natives-linux.jar, lwjgl-glfw.jar, lwjgl-glfw-natives-linux.jar, lwjgl-opengl.jar, lwjgl-opengl-natives-linux.jar\n    - **MacOS:** lwjgl.jar, lwjgl-natives-macos.jar, lwjgl-glfw.jar, lwjgl-glfw-natives-macos.jar, lwjgl-opengl.jar, lwjgl-opengl-natives-macos.jar\n\n## Features\n\n- Currently uses the original character set of the Kaypro II luggable computers.\n- The texture atlas of the font is generated according to input parameters. Both the distance between the scanlines and the width of the dots can be changed.\n- The characters have a modest shining appearance, applied through a bloom post-processing effect.\n- A scanline passes through the screen in fixed intervals, simulating a common problem of old CRT displays.\n- All characters can be fully changed for each frame render. Provides direct access to the internal character array for efficient manipulation.\n- Simulates the gradual fade-out of the characters.\n\nThe font is generated on the fly according to the input parameters. This is an example render, based on the Kaypro II character set:\n\n![Character set - texture atlas](/doc/img/character_set.png)\n\n## Usage\n\n- Instantiate the CRTerm.Terminal to display the main window. See the doc folder about the parameters.\n- Use the \"setCharacters\" or directly manipulate the character array accessed through \"getCharacterArray\". After the modifications upload the characters to the GPU, using \"uploadCharacterArray\".\n- See an example application at: [/src/TestApp/Main.java](https://github.com/bolner/CRTerm/blob/master/src/TestApp/Main.java) \n- Handle the keyboard inputs using the LWJGL functions.
