Graphics Introduction
Graphics (from Greek γραφικός; see -graphy) are visual presentations on some surface, such as a wall, canvas, computer screen, paper, or stone to brand, inform, illustrate, or entertain.

Graphics Printmaking
Printmaking originated in China after paper was invented (about A.D. 105). Relief printing first flourished in Europe in the 15th century, when the process of papermaking was imported from the East.

Graphics Photography
One difference between photography and other forms of graphics is that a photographer, in principle, just records a single moment in reality, with seemingly no interpretation.
|
Graphics for Web
In the 1990s, Internet speeds increased, and Internet browsers capable of viewing images were released, the first being Mosaic. Websites began to use the GIF format to display small graphics, such as banners, advertisements and navigation buttons,
|
Computer graphics
Computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content.
|
Computer graphics II
An SDL codebase is given with this tutorial, called QuickCG. All the C++ code in the articles uses QuickCG and its functions to draw graphics on the screen.
|
Graphics C++, SDL
This list contains all functions, global variables, etc... from QuickCG. If functions have default parameters, these are given as well.
|
Graphics QuickCG
This chapter contains a few easy examples to learn working with QuickCG and explore all it's functions.
|
Graphics Light and Color
This tutorial is about color, which is no doubt a very important aspect of computer graphics.
|
Graphics Color Model
HSL is another way to describe color with 3 parameters. RGB is the way computer screens work, but not very intuitive. HSL is more intuitive, but you need to convert it to RGB before you can draw a pixel with it.
|
Graphics Image
Image Arithmetic is where you take two images, do calculations on their color channels, and get a new resulting image that is a combination of the two.
|
Graphics 2D Drawing
This tutorial will describe a program that allows you to paint with various brushes like in professional painting programs.
|
Graphics Flood Fill
The purpose of Flood Fill is to color an entire area of connected pixels with the same color. It's the Bucket Tool in many painting programs. Here's an example: the original image is on the left.
|
Graphics Clipping
When drawing a 2D line on screen, it might happen that one or both of the endpoints are outside the screen while a part of the line should still be visible.
|
Graphics Fractals
Fractals have the property of self-similarity. One type of figure that fulfills this requirement, are Recursion Trees.
|
Graphics Sierpinski
There are quite a lot of fractals named after Waclaw Sierpinski, a Polish mathematician who lived from 1882 to 1969.
|
Graphics Julia
The Julia Set and Mandelbrot Set are those quite well known sets on the complex plane that create those pretty infinitely detailed images. They're so pretty, that there is even art created with them.
|
Graphics Fire Effect
This is a very short tutorial, about the very classic Fire Effect, and creating a fire color palette for it.
|
Graphics Tunnel Effect
One of those cool effects used in oldskool demos is the Tunnel Effect. This effect shows a tunnel in which you fly while the tunnel rotates, seemingly in 3D. This tutorial will explain how to make one.
|
graphics Raycasting
One of those cool effects used in oldskool demos is the Tunnel Effect. This effect shows a tunnel in which you fly while the tunnel rotates, seemingly in 3D. This tutorial will explain how to make one.
|
Graphics Raycaster
The core of the textured version of the raycaster is almost the same, only at the end some extra calculations need to be done for the textures,
|
Graphics Floor & Ceiling
In the previous raycasting article was shown how to render flat untextured walls, and how to render textured ones. The floor and ceiling have always remained flat and untextured however.
|
Graphics Sprites
The articles Raycasting and Raycasting II described how to make textured walls and floors, but something is missing. In a game, a world with only walls and floors is empty,
|
Graphics Filtering
Image filtering allows you to apply various effects on photos. The type of image filtering described here uses a 2D filter similar to the one included in Paint Shop Pro as User Defined Filter and in Photoshop as Custom Filter.
|
Graphics Fourier Trans
The Fourier Transform is an important tool in Image Processing, and is directly related to filter theory,
|
Graphics FT on Images
The extension of the Fourier Transform to 2D is actually pretty simple. First you take the 1D FT of every row of the image, and then on this result you take the 1D FT of every column.
|
Graphics DC Component
The center of the spectrum is the DC component of the picture, and represents the average color of the picture: if you calculate the IDFT of a spectrum with only the DC component left,
|
Graphics Texture Gen..
The XOR texture is a very easy to generate texture that looks fine. However, it's so overused that it's not a good choice to use in in a demo or intro release.
|
Graphics Random Noise
In nature, everything has a random look, while mathematical formulas typically don't generate random looking results, unless you use them well.
|
Graphics Clouds
To generate a sky with clouds, you can use the turbulence texture above, but with a blue-white color palette instead of black and white.
