     纹理图片

     
     需下载stb_image.h这个解码图片的库，该库只有一个头文件。

 
     具体代码：

          vertexShader.glsl

#version 330 corelayout(location = 0) in vec3 aPos;
layout(location = 1) in vec3 aColor;
layout(location = 2) in vec2 aUV;out vec4 outColor;
out vec2 outUV;void main()
{gl_Position = vec4(aPos.x, aPos.y, aPos.z, 1.0);outColor = vec4(aColor, 1.0);outUV = aUV;
}

 
          fragmentShader.glsl

#version 330 coreout vec4 FragColor;in vec4 outColor;
in vec2 outUV;uniform sampler2D ourTexture;void main()
{// 使用色彩填充// FragColor = outColor;// 使用图片纹理//FragColor = texture(ourTexture, outUV);// 使用图片纹理及色彩混合FragColor = texture(ourTexture, outUV)*outColor;
}

 
          main.c

#include "OpenGLClass.h"int main()
{OpenGLClass opengl;return 0;
}

 
          ffImage.h

#pragma once#include "Global.h"class ffImage

};

 
          ffImage.cpp
