Computer Graphics and Multi Media Practical programs in Go

CGMM Practical lab program written in Go

This repo contains variety of intersting agorithms I found in my Computer Graphics course I took in 5^th semester (2021). For the purpose of plotting I am using raylib-go; Go bindings for original Raylib library written in C.

To run the application follow these Intstructions:

Make sure you have installed go, and specified GOPATH.

1. You need C compiler as raylib depends on that, like Mingw-w64 or TDM-GCC. You can also build binary in MSYS2 shell.

2. Install raylib-go by typing in terminal.

   go get -v -u github.com/gen2brain/raylib-go/raylib

3. Run Test functions written in CGMM_test.go using your text editor or using command line:

   go test -run <test_function_name> CGMM_programs

   The command Line invocation may only respond with Pass/Fail if the test function don't initialize any GUI, ignoring any print statement.

   In that case resort to running tests using your text editor or create a main function and invoke the test function.

Algorithms covered:

• 📜line.go

  1. DDA (Digital Differential Analyzer)
  2. Breseham algorithm

• 📜clipping.go

  1. Cohen Sutherland clipping algorithm

• 📜circle.go

  1. Bresenham circle drawing algorithm
  2. Mid point circle drawing algorithm

• 📜fill.go

  1. Flood fill algorithm
  2. Boundary fill algorithm

The CGMM_test also contains a test animation function (a mini-game).

Other files:

• utils.go: Contains Utility functions used across the project.
• config.go: Conatins global variables like max height and width of application window.
• go.mod: Module file listing all other libraries the project depends upon.
