texture compression

One or three Paster methods: Textures refer to how materials are "wrapped" or "coated" on the ry. We call the texture-based image a map ). 1. Any standard element method: Check Generate mapping coords (generate texture coordinates). 3DS automatically generates the corresponding texture coordinates. 2. uvw editing modifier: You can change the

Before writingCodePreviously, we made a DDS file. I found a picture on the Internet, processed it as 512*512, and saved it as JPG. After Microsoft's DirectX texture tool is started, drag the image to it: Select the file format-> Generate MIP maps. You can see the word MIP 1 of 10 in the title bar of the image. This is because the size of the original image is 512*512, 256*256,128*128 ,..., 1*1. A series of subsampled images, plus 10 original ima

Shared memory access speed is very fast, but the capacity is very small. It is always a good choice to bind a large array to texture memory. Texture memory can be cached and has a large capacity.In the c

Note: The article is translated from http://wgld.org/, the original author Sambonja 広 (doxas), the article if there is my additional instructions, I will add [Lufy:], in addition, The WEBGL research is not deep enough, some professional words, if the translation is wrong, you are welcome to correct. The results of this demo runUsing multiple texturesLast described how to use textures in WebGL. Simple implementation of the texture is pasted into the qu

Texture coordinates 1. What is texture coordinates? The Direct3D texture coordinate system consists of a U-axis that represents the horizontal orientation of the image and a V-axis that represents the vertical orientation of the image. The coordinates (U,V) specify an element on the texture, which we call the

Texture Caching OverviewIn the game you need to load a lot of texture pictures, these operations are very memory and resources.When the game has an interface with a lot of pictures, the first point in the interface when the speed is very slow (because to load a lot of pictures), we can use Texturecache to load the texture ahead of time, such as loading the end, t

In the Corel Company's many products, the famous CorelDRAW in the vector map World Invincible, Photo-paint straight after Photoshop, and Corel R.a.v.e also in the animation production of a cup of soup, and some other tools are not so famous, But there is a real ability. such as Coreltrace, is a good tool to convert vector graphics, not only convenient, but also the effect is very good. Corel texture is the expert in generating textures. If you're cons

The overview includes the following 5 optimizations: Engine bottom-level optimization, texture optimization, rendering optimization, resource caching, and memory Optimization engine Optimization version 2.0 are optimized for the algorithm and more efficient than the 1.0 version. Version 2.0 uses the OpenGL ES 2.0 graphics library, and the 1.0 version uses OpenGL ES 1.0. Texture optimizationTextures are the

. For example, the color-depth rgba8888 is 32 bits, each of which is a byte. Therefore, a pixel occupies 4 bytes, which is an integer character. Example. A 480*320 image size occupies 480*320*4 bytes of memory. Generally, if the color of the image is not very high. The value of argb8888 (4 bytes) can be changed to that of argb1555 (2 bytes) (transparent channel a occupies 1 bit for image mixing) or argb4444 (if not for hybrid operations, use four digits ). Alternatively, if you do not need to u

PBRT reading: 11th Chapter Texture Section 11.1-11.4http://www.opengpu.org/forum.php?mod=viewthreadtid=5817 11th Chapter Texture To introduce textures into the material model, we now introduce a set of interfaces and classes. Recall that the materials described in the 10th chapter are based on parameters describing their characteristics (diffuse reflectance, gloss, etc.). Because the nature of the material

I. Summary The Finnish IT service company digia OYj said that the company would invest 4 million euros to buy Nokia's QT software business, digia OYj said, the company will invest 4 million euros to purchase Nokia's QT software business. QT is a very good team. I hope QT will develop better after leaving Nokia. After the previous tutorial, we have a preliminary understanding of the 3D world. Today we want to learn about light and texture filtering. Ii

Multi-texture textures Xiongbincsu@yahoo.com.cn 2007.06.25About Multi-texture: If a video card supports multi-texture, it means that it can combine several renders for one time. During this rendering process, you can add 0th, 1st, and 2nd objects to be rendered in different texture units. when the program draws a scree

Before introducing image compression encoding, consider the following question: why compression? You don't need to answer this question. Because the amount of data in the image information is amazing. For example, we can see that the data volume of an A4 (210mm * 297mm) image scanned with a medium-resolution (300 dpi) Scanner Based on the actual color? Let's calculate: there are a total of (300*210/25 .4) *

The following are all converted from the android game programming entry-level classic. For more information, see the source. To map a bitmap to a triangle, you need to add texture coordinates (texture coordinates) for each vertex of the triangle ). Texture coordinates map a point in the texture (uploaded Bitmap) to a v

OverviewWe all know that direct2d can load and display pictures, but don't know if you ever think that this 2D graphics engine can be blended with textures? If we can do texture blending, then our 2D graphics engine can do more things, such as the concept of masks, we can do a lot more work on the image.People who have touched the knowledge of 3D rendering know the shader, in 3D rendering
