The higher the Resolution, the more real-color textures, the more expressive the texture, but at the same time, the problem is that the memory occupied will multiply, and memory saving is very important in the current game. Therefore, texture
Original: HTTP://WWW.JIANSHU.COM/P/F7C3741F22AFThe Unity3d engine handles textures intelligently: Whether you put in png,psd or TGA, they are automatically converted into Unity's own texture2d format .In the texture2d settings option, you can set different compression formats for different platforms, such as iOS set to Pvrtc4,android platform set to RGBA16, etc.Well, it's very smart.However, in some advanced use, some situations are difficult to meet.

Unity texture summary, unity texture Reprinted please indicate the source We know that the performance of mobile games is inseparable from Art. Abuse of art resources often leads to a large amount of art rework. Therefore, it is very important to develop reasonable art specifications based on game needs. This article aims to solve two problems. First, what kind of specifications are there for art plotting?

1. Understanding Texturesthe textures in OpenGL can be used to represent images, photographs, and even fractal data generated by a mathematical algorithm. Each two-dimensional texture consists of a number of small texture elements, which are small pieces of data, similar to the fragments and pixels we discussed earlier. The most common way to use textures is to load data directly from an image file. each

In this article, we'll learn how to use texture mapping in OpenGL.Textures in Pengl can be divided into 1d,2d and 3D textures, and we need to specify the kinds of textures when binding texture objects. Since this article will take a picture as an example, we bind a gl_texture_2d texture to our texture object.This artic

One is the coordinate of the vertex position (X, Y, Z), and the other is the UV coordinate. What is UV? To put it simply, it is the basis for the texture to film on the model surface. To put it completely, it should be UVW (because XYZ has already been used, so it should be represented by three other letters ). U and V are the
