Dx9c provides a very simple method of using multiple rendering targets. The principle is to plot different information into many textures at a time, so that the textures can be merged to achieve some incredible effects. For example, you can save the
For the relief effect, stroke (edge detection)CodeIt's not complicated. It's just a little more complicated in theory, and the effect looks more attractive.
If the gray value at the edge of the image passes through a skip, we can calculate the
The so-called HDR means a high dynamic range. In normal display and bitmap, each channel is 8-bit, that is, the RGB component range is 0-255, which indicates that the actual color is obviously far from enough. In reality, the dynamic range of images
What is an element? Primitive
To put it bluntly, it is a set of vertices. These vertices describe a three-dimensional graph. A model produced by 3D Max is actually a set of graphic elements, which are composed of related lighting, materials, and

A little time has not been updated, the reason is that after one weeks of the bug results found to be less than an addition operation ....But no one is going to see the effect anyway. _ (: 3"∠) _

Have you heard that DirectX9.0 is released? If not, you should have listened to me now, then go to http://download.microsoft.com/download/b/6/a/b6ab32f3-39e8-4096-9445-d38e6675de85/. Dx90bsdk.exe Download the latest DirectX9.0 SDK, as I will use D3D9
Today we will learn the light source and material inside the Direct3D.Four types of illumination:
Ambient light
Ambient Light
An object is not directly irradiated by light, and it can be seen by the light that is reflected

The release of DirectX 11 has brought a lot of exciting new features. The use of computer shader for graphics post-processing, multi-thread rendering, out-of-order transparency, and other functions have
I started to learn DX from the beginning. I was too anxious to get started. I started to write programs without much basic knowledge. It was very difficult to solve the problem.

ArchitectureD3d and GDI are at the same level. The difference is
Time-based actions
Time unit: Ms
A slow computer can ensure the animation speed by dropping frames.
Read time in Windows
Use the timegettime () function. For details, see msdn.
You can use static variables to store the time at the beginning of the
There are three types of lights in d3d, which can make the 3D world look real.
I. Lighting type
1. Point Light)The uniform light emitted from a point to the surrounding area has the maximum illumination range and the brightness degrades with the
What operations are required for rendering? This varies and is complicated with the depth of application technology.
In general, the real-time information update section includes:

Http://hi.baidu.com/macsofft/blog/item/0b05dbd4069e7500a18bb79f.htmlThere is a more primitive article, where can I find a chance,However, I found that I am not suitable for thinking in the 3D world. I still need to study 2D image processing well.
Multi-stream technology has some benefits to performance and structure during rendering, but it is a learning to allocate model data to various vertex data streams for rendering.
Vertex data can be divided into the following
On the basis of initializing the form, I drew some simple ry work. After experiment, I thought it was basically implemented in the following order. First, we need to initialize two local variables to save the vertex and index data of the image, and

Next we will complete a more common effect-Mosaic. The mosaic of an image uses the color of the same vertex to represent an area of considerable size. It can be regarded as a large-scale reduction of the image resolution, while hiding some details
Real watercolor effects are difficult in shaderImplementationIt needs to perform some operations such as median filtering and then accumulate, and also needs to deal with the concept of strokes in. This article bypasses these concepts and only
