Computer Graphics Booting Up

Let's start with ModernGL

This lab stands to prepare the moderngl development environment. Below the steps and requirements for initial coding tasks. Please make sure to edit the python provided files; for dependencies, you can add the files you need.

1. Install moderngl and its dependencies
2. Make sure that the following programs run
   • 01_hello_world.py
   • 06_multiple_objects.py
   • 09_models_and_images.py
     • Modify this program to change the box's texture to a correctly aligned TEC logo
3. Document how to execute the 3 programs in the section below.

• For documentation and missing dependencies, follow these links:

How to run your program

The file 'environmet.txt' includes a full config of conda for this project

1. Install Miniconda

If Miniconda is not already installed on your system:

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh bash Miniconda3-latest-Linux-x86_64.sh

Follow the on-screen instructions to complete the installation and initialize Conda.

2. Create a New Conda Environment

Create and activate a new Conda environment with Python 3.10:

conda create -n myenv python=3.10 conda activate myenv

3. Install Required Packages

1. Install pygame:

   conda install -c conda-forge pygame or use pip install pygame

2. Install moderngl (for OpenGL context handling):

   pip install moderngl

3. Install PyGLM (for GLM functionality):

   pip install PyGLM

4. Install numpy:

   pip install numpy

5. Install Pillow (for image handling):

   pip install pillow

6. Install objloader (for handling 3D object files):

   pip install objloader

4. Adjust OpenGL Context Version in pygame

In your program, ensure the OpenGL context version and profile are set to 3.3 Core Profile. Insert these lines before the pygame.display.set_mode() call:

import pygame
# Set OpenGL context to version 3.3 core profile
pygame.display.gl_set_attribute(pygame.GL_CONTEXT_MAJOR_VERSION, 3)
pygame.display.gl_set_attribute(pygame.GL_CONTEXT_MINOR_VERSION, 3)
pygame.display.gl_set_attribute(pygame.GL_CONTEXT_PROFILE_MASK, pygame.GL_CONTEXT_PROFILE_CORE)

This ensures that the OpenGL context supports GLSL version 330 as specified in the shaders.

5. Running the Program

After setting up your environment and ensuring OpenGL context compatibility, run the included files.
