Just getting acquainted with computer graphics

Earlier this year I decided to finally invest time into learning about all things graphics.

I started by learning opengl fundamentals and all the basic graphics techniques used for real time rendering. I basically whet through all the tutorials that exist over here: http://learnopengl.com/

The most important thing I feel I learned was the limitations of a rasterization based render. Everything feels like a hack to me since it doesn’t really model real life.

I created a couple basic things with the opengl skills I learned.

Walls are created using a shader into an FBO, then the glass is shaded by projecting a ray to the wall and using gl's builtin refract.

Creating both took a total of 3 weeks while learning opengl (Lots of time spent debugging).

I have moved on to reading about physically based rendering. I’ve purchased this book:

It’s a 1000+ page book which reminds me of college.

At the same time I’m also investing in learning how to use Houdini. I’ve started with the basics, which would be learning how to model.

I’ve watched an 8 hour course in Houdini basics and have spent probably 15+ hours already on project where I want to create a pinball table model.

I started my journey to learn more about computer graphics about 48 days ago on August 14th. In just 48 days I’m fairly happy with the progress I’ve made. I’ve created this blog to reflect back on when I started and to track my progress.
