AIM OF THE PROJECT

Working on a library for performing GPGPU (General Purpose GPU) computations on BeagleBone Black using OpenGLES

Clone and build the Repository

Clone the repository:

git clone https://github.com/Pratham-Bot/GPGPU-with-GLES.git

Create the build folder and enter it:

mkdir GPGPU-with-GLES/cmake-build && cd GPGPU-with-GLES/cmake-build

Run the cmake command:

cmake ..

If running on your host, you need to specify the location of EGL and OpenGL ES libraries:

cmake .. -DEGL_INCLUDE_DIR=/usr/include/ -DGLES2_INCLUDE_DIR=/usr/include

Building the repository

make

Sharing internet connection from linux to BeagleBone Black

Internet connection can be established as shown here

Programming Languages used

C
GLSL

Libraries Used

GLES 2.0
GLFW- Graphics Library Framework (GLFW) allows users to create and manage OpenGL windows, while handling keyboard, mouse and joystick inputs. GLFW and FreeGLUT are alternatives to the same functions.
GLUT- The OpenGL Utility Toolkit Library provides high level utilities to simplify OpenGL programming, especially in interacting with the Operating System. GLUT is designed for simple to moderately complex programs focused on OpenGL rendering.
EGL- EGL (Embedded System Graphics Library) is the interface between OpenGL ES and the underlying native display platform.
GLEW- GLEW (OpenGL Extension Wrangler Library) is a cross-platform C/C++ extension loading library that provides an effcient mechanism to determine which extensions are supported on the platform.
GLAD- GLAD allows the user to include only those extensions which they wish to, leading to faster compile times. GLEW can detect which dependencies are available at compile time, leading to better adaptability.

RESULT

Triangle using GLUT library
Rectangle using GLUT library
Matrix Multiplication
Transpose of a matrix

Addition of a matrix with its own transpoe
