1. csplitterwnd creates a split form. The child form style must be child. Otherwise, an error such as "failed to create an empty document" will be thrown. 2. In the visual design of the dialog box, you can modify the tab key order after the design. Select the dialog box and choose format> Tab key order from the menu bar. 3. the user cannot adjust the window size. Bool cmainframe: precreatewindow

1, Glutinit, initialize the glut, this function must be called before the other glut use. Its format is more rigid, generally copy this sentence glutinit (ARGC, argv) on the can.2, Glutinitdisplaymode, set the display mode, where GLUT_RGB means using RGB color, and corresponding to the Glut_index (indicating the use of indexed colors). The glut_single represents the use of a single buffer, which corresponds to a glut_double (using double buffering). F

; // increase the rotation variable of the triangle (new)Rquad-= 0.15f; // reduce the rotation variable of the Quadrilateral (new)Return true; // continue running} This lesson is over again. Now you have mastered how to create objects in 3D space. The OpenGL screen must be imagined as a large drawing paper with many transparent layers. It is almost a cube composed of a large number of points. These points are filled with cubes from left to ri

GLUT Tutorial Keyboard example ------ Scenario roaming II In this section, let's take a look at the previous example. This time we will use advanced keyboard control. In the initialization section, we have two variables: deltaangle and deltamode. These variables control rotation and movement of cameras. When the value is not 0, the camera performs some operations. When the value is 0, the camera does not move. The initial values of these two variable

brighter, depending on the intensity of the light source. If the light source is pure red (, 0, 0), then the reflected light is only the red channel of the surface color of the object, because no blue or green part is reflected, if the object is pure blue, at this time, the object looks black because no blue light is reflected. We will specify the RGB value range of the light source color to [0-1], and then multiply the color of the light source and

If you have a pThread.h not found error when you use Cmake-g Xcode-wno-dev opengl_tutorial, it happens that you and I use the same version of the 2.8 cmake.Then try the Brew install CMake to install the latest version of the 3.0.2 CMake.OpenGL Tutorial Resources:first go to the URL [1], download the source code, unzip and use Cmake-g Xcode-wno-dev./opengl_tutorial generate the Xcode project file.Then you ca

Here I will only write a simple example. And when I draw a part of the plate, I will use a static variable (a local variable that can retain its value no matter when you call it) to express a cool effect. For clarity, I will rewrite the drawglscene function.You will notice that when I discuss these p

Abstract In the previous article, we introduced simple shading and proposed a lighting model to simulate a light source. However, the story about light is not over yet... Today I want to learn about directional light, spotlight, per pixel shading, and halfway vector. For the principle and mathematical description of the light source, see: raytracing Algorithm Theory and Practice (3) Illumination Direction Light Source The direction light source has tw

Math3d. h Vector3f Vector3f::Normalize() { const float Length = sqrtf(x * x + y * y + z * z); x /= Length; y /= Length; z /= Length; return *this; } Note: The right vector is calculated based on the cross product.

Original post address: http://ogldev.atspace.co.uk/www/tutorial08/tutorial08.html The scaling matrix is relatively simple. It aims to scale the object length (or, scale the component of the vertex in the three axes). Of course, you can also select a certain axis direction to scale. The reason for scaling objects is mainly to match the sizes of different objects in the world space, because 3D object modeling is in the model space, usually (x, y, z) the range is (0,

the three pre-defined constants in glut. H, or their or combinations. The three constants are: 1: glu_active_shift: return it. When you press shift or Caps Lock, note that this value is not returned when both are pressed. 2: grant _ active_ctrl: return it. Press ctrl. 3: Maid: returns it when the ATL key is pressed. Note that the window system may intercept some modifiers, so no callback occurs. Now let's

1. welcome to the third and last course of this tutorial. If you have learned the first and second lessons, you have mastered the basic installation and programming knowledge of MySQL and PHP. Next we will introduce some other PHP functions, which may be useful to you, so that your development process is simpler than SyntaxHighlighter. all (); 1. basic functions

tags used at the end of the program. Now let's create another file, which contains the real PHP program code. Try the following code. Of course, make sure that the MySQL database server is running. 　 $ #@ 60 ;?
