texture compression

There are three main factors that determine the size of a texture resource: Resolution, format, and Mipmap are turned on.The loading recommendations for texture resources are as follows: 1, strictly control the use of RGBA32 and ARGB32 texture, in the premise of ensuring the visual effect, as far as possible to use "good enough" principle, reduce the resolution o

The Texturepacker tool is designed to package multiple images into a single large pictureThe purpose is: 1. Save memory space, 2. Reduce the number of texture rendersbecause Android and iOS games are rendered through OpenGL ES, OpenGL ES requires that the texture must be 2 of the size of the n-th square,if not, it expands to the nearest 2 of the n-dimensional dimensions (by filling transparent pixels)most i

The local binary patterns method is a method used for image feature classification in computer vision. In September 1994, we first proposed [43] [44] by T. Ojala, M. pietik äinen, and D. Harwood for texture feature extraction. Later, the combination of the LDA method and the hog feature classifier improved the detection performance on some datasets [45. The following describes how to extract a feature vector from a local string: First, the detection w

How to Use the atlasc texture set (generated using TexturePacker) when developing a game using SpriteKit in xcode7.3) Because the resource file to be used is a small set of images, we need to first generate a large image and include all the small images in it, the best way is to use a third-party tool to implement this function. 1. First download TexturePacker. The latest version when writing this article is 4.1.0. For: https://www.codeandweb.com/bl

they will perform better in terms of performance, and are more widely supported. * To check availability of those formats the checkdeviceformat () API shocould be used.-Thus for a 16-bit depth surface you wowould call for ATI:Hres = d3d-> checkdeviceformat (adapter, devicetype, adapterformat, d3dusage_depthstencel, d3drtype_texture, fourcc_df16 );-And for NVIDIA:Hres = d3d-> checkdeviceformat (adapter, devicetype, adapterformat, d3dusage_depthstencel, d3drtype_texture, d3dfmt_d16 ); note that i

The correct definition of the original WPF 3d:meshgeometry3d texture coordinatesTo make 2D-based textures appear in 3D objects, we must define the texture mapping coordinates of the 3D mesh objects. In WPF, this feature is passed through the Meshgeometry3d.texturecoordinates property.The corresponding coordinates of the LinearGradientBrush texture are the same as

Unity3d Shaderlab Simulated Texture movementIn this article, we're going to talk about the effect of a UV map on a shader's scrolling effect, such as a scene that can be used in rivers, waterfalls, lava, and so on. is one of the basic techniques for creating texture animations. So prepare a new shader file and a new material.This time we first add some code to the Properties:Properties {_maintint ("Diffuse

Recently, it is found that the texture of Max may cause problems to the producers. The common problem is the uncertainty of the texture path. The root cause is that the Directory creation is inconsistent. There is a common problem,Max opening a file with a lot of lost textures will lead to very difficultIt takes 18 minutes to open a file on my machine.Move the file to the project directory to openIn less th
