Computer Graphics Unveiled

In order of understanding how geometry is displayed on your computer screen, may it be 2d or 3d, one needs to understand what math people came up with to simplify our life. Basically, every computer programme that displays some kind of geometry/object on your screen probably uses these tricks. In 3d, without this, we would still have only very simple graphics.

We shall not write tens of pages explaining how this math actually works, we shall do a visual presentation of it. All modern graphics hardware, game engines, DirectX, OpenGL already have an encoded matrix helper function. Once you understand what these are, you will simply use matrix functions in order to have the desired effect.

If you ever wondered how your desktop/laptop computer calculates and presents all the 3D graphics you see, if you are a beginner and want to learn how – this is the article for you!

It presents basics of how light and surfaces are interacting, the simply presented math (the math is actually quite complex, but presented in “plain english” so anyone can understand) will shed a lot of light on the subject. It also contains functions used by popular shader languages so one can learn to use those too.

In the following series we shall go deeper and deeper into more complex structures of 3D lightning, shaders, optimizations, normal mapping, displacement mapping… and I shall  explain how you should think to achieve to programme your favorite graphics card (may it be NVidia or ATI, they both work just fine) and have the most out of it!

Examples and work is accompanied with NVidia’s Cg shader code, OGRE materials and meshes, so you can implement what you learned right on the spot!

So, let’s dig in!

I finally catch’d time to select some photos I took while my travelings! I uploaded those to HERE so you can check it out too.

These were taken back home and at the Canary Islands, where I lived the last 5 months.

Cheers!

After downloading our eBook, for simpler understanding and excersise all the files mentioned can be downloaded here.

I’ve been hard at work with Dr Wordpress (Website In A Weekend) creating an ebook we believe is a completely fresh approach to handling graphics image work… because we’re writing for you, the WordPress user without a huge graphics budget… that needs to get this “graphics thing” handled.

On Wed April 15, we’re going to release — for a limited time — the first chapter of “Fastest WordPress Graphics.”

This first chapter dives into designing and creating a “favicon,” that little image that sits on your web browser tab, in the URL window, and gets listed out with your bookmark:

Now, the entire ebook is $17, but we’re releasing Chapter 1 for free. We want you to have first crack at the material, and we’re interested in getting your feedback on how we can do even better in the rest of the ebook.

Here’s some of what you’ll find:

• Why favicons are necessary components of a well-designed website.
• “Best practice” design strategies for extremely small graphics. What’s small is good, but small is harder.
• Common pitfalls incurred using automated web-based tools. You definitely want to avoid these time wasters!
• Specific techniques in Photoshop (with screenshots) for creating favicons really fast and really accurately.
• Links to every file and image shown in the ebook. (We’re giving you Photoshop project files… hardly anyone does that… it’s worth at least triple the price of the whole ebook just for those alone… if you could even get them from your artist!)
