我是 GLFW 的新手，做了一个简单的纹理映射程序。问题是在运行程序时内存资源不停地增加，我可以在任务管理器中清楚地看到。
运行程序几分钟后，我的电脑风扇加速并出现加热问题。我该如何解决这个问题？
这是纹理加载功能的代码
GLuint LoadTexture(const char* TextureName)
{
GLuint Texture; //variable for texture
glGenTextures(1,&Texture); //allocate the memory for texture
glBindTexture(GL_TEXTURE_2D,Texture); //Binding the texture
if(glfwLoadTexture2D(TextureName, GLFW_BUILD_MIPMAPS_BIT)){
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_NEAREST);
return Texture;
}else return -1;
}
这是绘图功能的代码
void display()
{
glClearColor( 0.0f, 0.0f, 0.0f, 0.0f ); //clear background screen to black
//Clear information from last draw
glClear( GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);
glMatrixMode(GL_MODELVIEW); //Switch to the drawing perspective
glLoadIdentity(); //Reset the drawing perspective
glTranslatef(0.0f,0.0f,-35.0f); //Translate whole scene to -ve z-axis by -35 unit
GLuint text2D;
text2D = LoadTexture("cicb.tga"); //loading image for texture
glEnable(GL_TEXTURE_2D); //Enable texture
glBindTexture(GL_TEXTURE_2D,text2D);//Binding texture
glPushMatrix();
glBegin(GL_POLYGON); //Begin quadrilateral coordinates
glNormal3f(0.0f, 0.0f, 1.0f);//normal vector
glTexCoord2f(0.0f, 0.0f); //Texture co-ordinate origin or lower left corner
glVertex3f(-10.0f,-11.0f,5.0f);
glTexCoord2f(1.0f, 0.0f); //Texture co-ordinate lower right corner
glVertex3f(10.0f,-11.0f,5.0f);
glTexCoord2f(1.0f, 1.0f);//Texture co-ordinate top right corner
glVertex3f(10.0f,-1.0f,-15.0f);
glTexCoord2f(0.0f, 1.0f);//Texture co-ordinate top left corner
glVertex3f(-10.0f,-1.0f,-15.0f);
glEnd(); //End quadrilateral coordinates
glPopMatrix();
glDisable(GL_TEXTURE_2D);
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D,text2D);
glPushMatrix();
glBegin(GL_POLYGON);
glNormal3f(0.0f, 0.0f, 1.0f);
glTexCoord2f(0.0f, 0.0f);//Texture co-ordinate origin or lower left corner
glVertex3f(-10.0f,-1.0f,-15.0f);
glTexCoord2f(10.0f, 0.0f); //Texture co-ordinate for repeating image ten times form
//origin to lower right corner
glVertex3f(10.0f,-1.0f,-15.0f);
glTexCoord2f(10.0f, 10.0f);//repeat texture ten times form lower to top right corner.
glVertex3f(10.0f,15.0f,-15.0f);
glTexCoord2f(0.0f, 10.0f);//repeat texture ten time form top right to top left corner.
glVertex3f(-10.0f,15.0f,-15.0f);
glEnd();
glPopMatrix();
glDisable(GL_TEXTURE_2D); //Disable the texture
glfwSwapBuffers();
}
如果有人想通过运行exe查看问题，那么我可以提供下载链接。
