Graphic programming is the magic behind video games, movies and scientific simulation simulations. Every explosion, particle, and glare you see on a computer screen is handled using a video card. In addition, every pixel you see is achieved through GPU rendering and graphic programmer software, because modern operating systems use GPU rendering. This
Qt 3D Research (10): Stroke rendering (contour rendering) and silhouette ShaderBefore writing two articles, introduced me in the edge detection above research, actually uses the GPU to carry on the edge detection to the rendering image, the premise is needs to carry on the two times render, the previous time renders th
Comments: WebGL has started a new era of 3D rendering of web pages. It allows you to render 3D content directly in the canvas without using any plug-ins. Do you feel particularly surprised to see this, webGL has a good Chinese tutorial, that is, the first link in the reference below, so I will not make an axe to the class here. The following content is just a bri

I have studied the technology of wooyoogame over the past few days. The 3d display implementation of this website looks very simple. I have made a simple tutorial for you.

process textures are based on some kind of noise function.
3D texture is no longer a two-dimensional planar image, it is a volumetric texture, can be seen as a variety of different cube materials, as dozens of, hundreds of layers of 2D texture overlap, each layer is a simple 2D texture. Each point in a 3D texture has a three-dimensional relative coordinate within the texture's interior space.

Using WPF in applications to generate 3D scenarios can provide users with good visual display results. On the contrary, the requirements for computer system resources and hardware devices are also very demanding. Next, I will focus on the performance optimization considerations for processing 3D graphics in WPF.

Since learned the Turtle module, drew a lot of simple strokes. Like Piglet Paige, Doraemon and so on, but these still do not allow people around to feel the power of Python, is still every time the force will be beaten face. It's like you painted this with turtle.Someone else took out this.What to do? In the face of the library so rich Python, not a library, we have another library. That's the Pyray library.Pyray Library IntroductionThe Pyray library was created in January 2018, although the bes
Finally, I have finished talking about the basic concept of space ry in the first three articles. Now I can say something practical.
For a long time, I have always hoped to record some of my 3D knowledge in the most easy-to-understand language as a series of popular science articles for everyone to take a look.
About a decade ago, I had my first computer and soon saw the charm of

For any 3D application, pursuing realistic scenes is a complete goal. The result is to make our scenarios more complex and more precise, this will inevitably bring a huge load to the graphics hardware so that the frame rate cannot be set in real time. Therefore, rendering optimization is essential. Before re

This is my second learning of OpenGL. My first learning was in the sophomore computer graphics class. It was just a careless look at OpenGL. Now, after two years, I plan to make a complete and systematic learning of OpenGL for three purposes: 1. familiar with OpenGL programming. 2.

What has been done to the various stages of the graphic rendering pipeline? It is always unclear. Every time I read the book, I still read the book after a while. I did a good job in this CG tutorial, specially picked for reference. -By Shenzi/2010.3.25

The z-order 0 is always owned by a view that can overwrite the entire rendered object. By default, ogre clears the color and depth buffer of the view. However, you can disable these buffer cleanup operations. A viewport is the unique interaction point between a renderin

A simple understanding of rendering may be like this: it is to convert the description of a 3D object or a 3D scene into a two-dimensional image, and the generated two-dimensional image can well reflect a 3D object or a
