On the other hand, the development of OpenGL specifications and standards is also affected by the conflict of interests between software and hardware manufacturers, and the consensus cannot be reached. On the MS side, however, it is just working with ATI and NVIDIA to develop DirectX API specifications, and has the final key discretion, so it can be quite smooth and rapid continuous development. In this case,After DirectX 9 was launched, it wa

GPU acceleration only supports the following animations: Scale, Rotate, Changing Opacity, Clipping (only if clip is rectangular), and others are not supported, such as Perspective 3d effect animation. 2. if the GPU memory is insufficient, Silverlight uses t

Since this book contains a lot of content, a lot of content is repeated with other books that explain cuda, so I only translate some key points. Time is money. Let's learn Cuda together. If any errors occur, please correct them. Since Chapter 1 and Chapter 2 do not have time to take a closer look, we will start from Chapter 3. I don't like being subject to people, so I don't need its header file. I will rewrite all programs. Some programs are too bor

Vertex coloring. It can get the current state in OpenGL, and GLSL built-in variables are passed. GLSL uses C language as the basic high-order coloring language, avoiding the complexity of using assembly language or hardware specification language. This section comes from Baidu encyclopedia and requires attention: Programs Written in GLSL are executed in the GPU, meaning that the coloring program does not t

3 DMAX Model Application in OpenGL Fang Bin (Aircraft Design Institute of guihang group, Anshun 561000, Guizhou) Abstract: This article describes how to implement 3 DMAX data model program control in OpenGL 3D programming. The results can be used in aircraft flight motion simulation and real-time flight monitoring.

Android OpenGL ES plotting tutorial 3: Drawing GraphicsAfter defining the shapes to be drawn by OpenGL, you certainly want to draw them. Using OpenGL ES 2.0 to draw a graph may require more code than you think, because the API provides a large number of graphic rendering pipeline control interfaces.This chapter describ

Crop a plane (also called a projection plane) and its coordinate system. Note that the coordinate system of the plane is not fixed. We can operate on it to make our projection plane work in any coordinate system (e.g ., we can specify that the origin of OpenGL ES is in the lower left corner

Note: The following content is from OpenGL getting started tutorial. Select a part of content for learning ~~~ When we draw a geometric image above, do you think our plot scope is too narrow? Coordinates can only be from-1 to 1, and can only be the right X axis, Y axis up, Z axis vertical screen. These limitations cause a lot of inconvenience to our drawing. We live in a 3D world-if we want to observe an object, we can:1. Observe it from different lo

operation speed is fast, but it is slightly less convenient to program, and the image effect is also worse than the RGB color. StarCraft may represent the screen effect of a 256-color table. Although it can run smoothly on a very bad PC, from the current perspective, the screen effect is insufficient.Currently, the performance of PC is sufficient to use RGB color in various scenarios. Therefore, the index color is not mainstream in PC program development. Of course, some small devices, such as

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

Call OpenGL in cocos2dx (3.X) I have been using pomelo to write back-end data for the past few months. Now the project is coming to an end and I have finally had time to study OpenGL-related things. OpenGL itself is cross-platform, but the development environment of each platform is not the same. It is much easier to p
