achieve redrawing to see the rotation effect.The main part of the Experiment Code and explanation (appendix has the Project code download link address).Glwidget.cpp:#include "glwidget.h" #include "ui_glwidget.h" #include Summary:OpenGL in the realization of planar graphics coloring and rotation, the implementation is relatively simple, only need to assign the corresponding function.References:http://nehe.gamedev.net/http://www.owlei.com/DancingWind/http://blog.csdn.net/qp120291570/article/detai

{ float R; float g; float B; float A;} D3dcolorvalue;A single-precision number is used to measure the luminance value of each component, and the value range is 0~1.But this structure is seldom used. Because the d3dcolorvalue structure can be converted to D3dcolor, and D3dcolor is more powerful than the function methods that d3dcolorvalue contains.2. Coloring:Here's the first thing to say about Rasterization: a simple understanding, in real life, if you draw a triangle, each line is

In the crash, the translation is complete, no matter what the translation is. For a long time, I have never been so eager to translate articles. I am outsourced every day and I am only allowed to do what I want to do at night. I should be a night-jumping animal, so that I can satisfy my preferences and habits? Due to the coincidence, since last year, since being forced to access this technology at work, unreal's deferred shading has been getting depre

Original address: http://www.verydemo.com/demo_c284_i6147.htmlFirst, Deferred shading Technology IntroductionDeferred shading is a technique that defers lighting/ rendering calculations to a second step. We do this to avoid rendering the same pixel multiple times (more than 1 times).The basic ideas are as follows:1, in the first step, we render the scene, but unlike the usual case of applying a reflection m

As we mentioned before, in the Word2007 document, the table border settings, you can set from the Border and Shading dialog box, and understand the border settings, then the next to understand the table shading method, simple to operate, or from the Border and Shading dialog box. Step 1th, open the Word2007 document window, and in the Word table, select one or m

the cache content: void CGL::clean(){ glDeleteBuffers(1, vertexbuffer);prog.deleteProgram();glDeleteVertexArrays(1, VertexArrayID);} The running result is as follows: ADS coloring (ambientdiffusespecular shading) ADS is the lighting model mentioned above, also called Phong reflection model or Phong Shading Model. The computing model of illumination is: The vertex shader needs to be modified to calcul

In view of the inefficiency of the traditional forward rendering for multi-light source rendering, various deferred rendering methods have been proposed and widely used. For example, deferred shading and the subsequent deferred lighting. The most important difference between the deferred method and the traditional forward rendering method is that it improves the efficiency of Multi-light source rendering. It is to convert the calculation of the light

Per-vertexRendering technology is used to perform rendering calculations for each vertex, and then associate the calculated color value with this vertex. Then the smooth rendering effect after color interpolation is performed on the polygon surface. This is also calledGouraud shading. In the early OpenGL version, it is the default rendering technology. Sometimes we need to hide one effect: there is only one color on a polygon, rather than the smoothin

By setting paragraph shading for Word 2007 documents, you can highlight the contents of important paragraphs to enhance readability. To set paragraph shading in Word 2007, the following steps are described: Step 1th, open the Word 2007 document window and select the paragraph you want to shade. Step 2nd, in the paragraph group of the Word 2007 start ribbon, click the

In Word2007, users can set a single color background color for a Word table, and you can set pattern shading for a specified cell, as described in the following steps: Step 1th, open the Word2007 document window, and in the Word table, select one or more cells that you want to set shading patterns in. Step 2nd, switch to the Design tab in the Table Tools Ribbon, and click the Border Drop-down button in th

Next, we mainly use the shading in the "pattern shading" settings, small set to take an example to carry out the demo again! Operation Steps 1, start Word2007, open a document for everyone to demonstrate, the left mouse button press and hold, select a paragraph, click the Start tab under the Border line button, from the Drop-down menu select "Borders and Shading
