The getleveldesc function is in msdn:Retrieves a level description of a texture resource.Hresult getleveldesc (Uint level,D3dsurface_desc * pdesc);ParametersLevel[In] identifies a level of the texture resource. This method returns Surface description for the level specified by this parameter.Pdesc[Out] pointer to a d3dsurface_desc structure, describing the returned level. This function is used to obtain the width and height of the loaded image and some information. Usage: d3dsurface_desc DE

possibility that the texture will be cached. Minimize texture switching and draw objects with the same texture in a centralized manner. Use square textures whenever possible. The fastest texture is 256x256. Four 128x128 textures are spliced to 256x256.Connect World-View Matrix and set ViewMatrix as Identity to reduce Matrix multiplication.Dynamic texture. First, check D3DCAPS2_DYNAMICTEXTURES to determine whether the hardware is supported.Second, dynamic textures cannot be placed in MANAGED.Poo

Lecture by ptexArticle, This article is between writing notes and not writing, but there are some highlights (oneCodeA copy of data) is good. An article about NV before ptex has been introduced. In short, texture is broken into a large texture and used in Atlas, which can greatly save space: Mipmap computing code: This is a record, but let's try again: Efficiency In actual use of ptex, it is much m

the Pixel BufferThe image data information in ogre is encapsulated in pixelbox objects. Note that pixelbox itself is stored in the GPU, but the real textures are saved in the memory, not in GPU. The pixelbox In the GPU stores the description of the pixel format and location information in the memory. However, pixelbox does not have the memory management function. It can only operate data through the stored memory pointer. The pixel box provides a method to index pixels by depth, height, and wid

, fill in the parameter 1. As follows: (width, 1, 1), two-dimensional texture (width, height, 1) Pixel Buffer update Ogre provides two methods to update the pixel buffer. 1: manually create a texture and put an image into the texture. We can:CodeImage IMG; img.load(“xxx.jpg "," General "); texture ptex = texture: getsingleton (). createmanual (.... ); Ptex-> getbuffer (0, 0)-> blitfrommemory (); 2: Lock

In the previous article, we talked about how to install and use the MacTeX that supports Chinese in Mac OS X (the author uses 10.10,hackintosh). In fact, MacTeX has been installed by default to support multiple languages, such as Japanese (due to the presence of Ptex, it may be easier to compose Japanese).In fact, Latex is a Tex-based typesetting system. Tex was just born, and although it can be written out in very beautiful articles, but its code is

the PDF file is encrypted, you can use this method to decrypt it. Getdocumentinfo (): Retrieves some information about a PDF file. The return value is a documentinformation type, and the direct output will get a message similar to the following: {'/moddate ': "d:20150310202949-07 '", '/title ': ", '/creator ': ' LaTeX with Hyperref package ', '/creationdate ':" D : 20150310202949-07 ', '/ptex.

home Page). However, with the popularity of PDF since 2000, the use of PS gradually decline, the community inside the PS processing tools are not much richer than the PDF, more or less rely on Ghostscript, and even dvips now do not support bitmap file illustrations. There is an interesting thing, such as the German students said there are still many people in Germany in the use of plain Tex, I am not too surprised, for English and so on, in fact, plain very useful, but also a part of the Russ
