glint and glsizei ),F indicates a 32-bit floating point number (OpenGL defines this type as glfloat and glclampf ),D indicates a 64-bit floating point number (OpenGL defines this type as gldouble and glclampd ).V indicates that several parameters passed will use pointers. See the example below.These functions have the same function except for the type and number of parameters. For example, the functions of

Learning OpenGL (3) drawing spiral graphics [Email protected] Http://blog.csdn.net/kezunhai In OpenGL, graphics are composed of some basic elements, which interpret a set of fixed points or vertex lists as some images drawn on the screen. The smallest element in OpenGL is a vertex. There are 10 elements in

This time, OpenGL is used to draw a circle, and a solid pentagram is drawn in the middle. 1. Draw solid five corners: Since the previous use of polygen painting will fail, maybe the GPU hardware will be different, so the use of polygen to draw a solid five-pointed star is not reliable; Therefore, polygen is not required to draw a star using a triangle. 2 circles Because there is no circular shape in glew, we can only manually set the vertex

Nested display list To support more complex plotting, the display list also supports nesting. That is, when creating a display list using glnewlist () or glcalllists () call the defined display list. Theoretically, the number of nested layers in the generated list can be 2 ^ 31-2, but in fact there are two reasons why this is not supported. First, when the number of nested layers increases, it takes a lot of resources and time to create a display list. Second, even if you can create multi-level

Wow, how powerful is this computing power, and Intel even has a CPU with multi-core hyper-threading. NUMA architecture computer Multi-core CPUs look powerful on the surface, but they lead to a new problem. Now, multiple cores are simultaneously acce

virtual base class has become a special term designed by C ++ Oo, it provides a virtual interface without defining any data. The Visual C ++ 6.0 Compiler regards an empty virtual base class as a part of the beginning of the derived class object. Therefore, the subsequent 1 bytes is saved, and there is no problem with the subsequent alignment, therefore, the actual execution result is 4.

Shadow Map (3), shadowmapStudy on Shadow Map (III) Recently, I have suffered a lot from my own projects. The key point is to implement Shadow Map ). In order to achieve the goal, I have read a lot of relevant information on the Internet and some cases. It took me a month to achieve this effect. The effect of shadow ing has been described in the upcoming Qt 3D release, in KDAB, Shadow Mappingin Qt3D 2.0 implements Shadow ing on the Qt 3D framework. How

EGL is a set of platform-independent APIs provided by khronos group. Its functions: 1> communication with Native Windows system;2> query available configurations;3> Create a drawing surface available for OpenGL ES );4> synchronize rendering between APIs of different categories, for example, between OpenGL ES and openvg, or between

One,vita), it is very difficult to generate shaders on these platforms in real time.2. They cannot work with materialpropertyblocks, cannot be used on the rendering of Unity's sprite, nor can it be used on animated materials.3. They are only suitable for doing very simple things, you make a simple fixed function shader, then found that need to add more features, there is no way to do more.How does a fixed function shader perform on unity? Why? Most p

, the default Coordinate System of the cocos2d-x is not like this, but not all, When you touch an event, the coordinates that you touch are the UI coordinates, As shown in the following figure, Vec2 touchLocation = touch-> getLocationInView (); Of course, we can also perform Coordinate Transformation to convert it into the default coordinates of the cocos2d-x: Vec2 touchLocation2 = Director: getInstance ()-> convertToGL (touchLocation ); 3.

They don't work on the host (PS4, Xbox one, vita), and it is very difficult to generate a shader in real time on these platforms. 2. They cannot work with MaterialPropertyBlocks. They cannot be used in unity Sprite rendering or animated materials. 3. They are only

. Director (director) Director controls the entire game, often with some scheduling control; in Cocos2d-x 3.x, director uses a singleton mode, which has only one instance during the entire game run. Director is the whole Cocos2d-x 3.x core, is the entire game navigator, in the game, generally by director to complete the following operation control: Initialization of 1.

Cocos2d-x game Original article, reproduced please indicate the source: http://blog.csdn.net/sfh366958228/article/details/38701767 Through the first two study notes, we can easily find that ccscene, cclayer, ccsprite, ccaction, and other elements are child classes of ccnode. However, the title of "father of everything" is a bit exaggerated, after all, there are components such as ccdirector and cccamera that do not inherit from ccnode. But ccnode is definitely a core of Cocos2d-x, we can unders
