OpenGL path (6) texture, opengl path texture

OpenGL path (6) texture, opengl path texture

To patch an object, the image width and height must be a power of 2.

The Code is as follows (Some compilers do not contain glaux and can be configured by Baidu search. If you have any questions, go to the QQ Group 116920287 for consultation)

The image is as follows: 1.bmp

Continent 6 Textures?

. This figure shows the glove. My original. It is already posted on the Forum. In fact, many of my original projects are mouse painting. I think PS is hard to make the desired effect. It is troublesome to change it once. So I think direct mouse painting is better. This is a picture of my mouse.




Why can't someone know why I can't open the sixth continental Paster ??

I couldn't open it a few days ago. Then I went to the Q group to ask the webmaster. The address is www.tongcx.com/this6. Can you try it? The webmaster said that you don't need to remember the website. Baidu just search for the first paid station on the sixth continent, if you cannot find this address, search Baidu.
