texture compression

Unity3d Shaderlab compressed mixed texture mapTextures can be used to store large amounts of data, we can package multiple images on a single RGBA texture, and then extract these elements through shader code ,we'll be able to use each image's RGBA the message of the channel as a separate texture. This usage scenario, especially on the ground, has obvious advantag

Fixed: I looked at the terrain of the torque engine demo and found that he had used at most three textures in a square. Three texture stages are required for the three pasters, and two stages with Alpha values are added. A total of five texture stages are required. This is too demanding for the video card. At least my video card supports only four texture stage

Rendering to textures is an advanced technology in d3d. On the one hand, it is very simple, on the other hand it is very powerful and can produce many special effects. For example, the luminous effect, Environment ing, and shadow ing can all be achieved through it. Rendering to texture is only an extension of rendering to the surface. We only need to add more. First, we need to create a texture and take pre

Original link1. OverviewThe data in the texture memory is stored in memory in the form of one-, two-, or three-dimensional arrays, which can be accessed through the cache and can be declared larger than the constant memory.The operation to access the texture memory in kernel is called texture pickup (texture fetching).

We can understand it by comparing the effects of different formats.Effect of uncompressed RGBA32 format (all GPU support) Please ignore the seam problem, that is the art of UV to show wrong ...ATC compression format (format supported by the Adreno series GPU) The naked eye almost does not make the difference, the saturation has slightly reduced ps:dxt, the PVR effect also is similar, here does not post, the interested person can test underAnd finally

LibGDX Game Engine-2-Image Rendering This series of blog posts are from Sina's blog-xiaotudou. I have added my own understanding and modifications to this article! Method Type 1. Use Texture as the image container and draw the image on SpriteBatch. 2. Use TextureRegion to intercept texture and draw it on SpriteBatch 3. Use the Sprite genie to set textureRegion, pass in SpriteBatch, and draw the image

Texture of the performance: object Material and surface formed visual characteristics, such as: material hard or surface texture of the rough or fine finish of high or low, transparent feeling strong or weak, loose or tight texture or even, material light or heavy and so on. Texture and a variety of materials on the

Texture filtering When discussing texture coordinates and sampling, you may have noticed that there is no texture mapping object that allows one by one of the elements on the texture map to correspond to the pixels rendered on the screen. The camera is located at any point in the textured object and is viewed from any

IntroductionThis chapter describes some of the basic aspects of 2D graphics, including how to use Texture,textureregion and SpriteBatch.Texture slightly. SpriteBatch LIBGDX uses SpriteBatch to complete texture mapping and displays all work on the screen that are textured-mapped quads. It makes drawing graphics on the screen extremely simple and optimized. It works in the screen coordinate system, using the

When it comes to textures, it's hard to describe them in words: I'll start with the picture: Have you found anything?Look carefully:Our second model is to talk about the concept of texture mapping by giving the model some realism through texture mapping techniques. Then we must not think that the second picture will certainly use texture mapping is not necessari

Texture: A texture saved in the GPU buffer.Textureregion: Defines a texture for a rectangular area. The main function is to playable the rectangular area that needs to be used from a piece of texture.Sprite:holds the geometry, color, and texture information for drawing 2D. This class is inherited from Textureregion, is

Sprite Frame Cache Introduction Spriteframecache mainly serves the texture images of multiple pieces of broken images. This texture in a large map contains a number of small images, directly through the Texturecache reference will be a lot of inconvenience, and thus derived from the processing of the wizard frame, that is, the captured texture information stored

Write in frontPrior to learning 2D texture mapping, there are actually other types of textures that we need to learn further, the cube texture (cubemaps) to be learned in this section is a technique for compounding multiple texture images onto a cube surface. In the game the use of more sky bounding box can be implemented using CUBEMAP. The sample programs in thi

Now we will gradually coding the texture ing Based on mytutoriald3d11_5, because this project only draws a triangle so that we can easily paste a texture, then, change the texture sampling status and observe the texture changes. First, we do not assign a color value to each vertex, instead of a

: Golden point time and space :: Back 8: texture People are always easy to ignore things around them. The more familiar and intimate they are, the more they will happen. Why? I do not know, but since it has already happened, there is no need to blame anything.Taking actual actions immediately is the only thing we should do!What is texture?
