Hello everyone,

I've been struggling for days with certain piece of code in C++ and OpenGL that were supposed to detect object selection. The code worked perfectly till I introduced textures and now I see no response.

Here's the code:

void MouseFunc(int x, int y)
{

glutSetWindow(id) //I have several subwindows
glDisable(GL_LIGHTING);
glDisable(GL_COLOR_MATERIAL);
glDisable(GL_TEXTURE_2D);

glDrawBuffer(GL_BACK);

//code that draws a single colored figure

unsigned char pixel[3];
GLint viewport[4];
glGetIntergv(GL_VIEWPORT, viewport);

glReadBuffer(GL_BACK);
glReadPixels(x, viewport[3] - y, 1, 1, GL_RGB, GL_UNSIGNED_BYTE, pixel);

//code for comparison between read and stored colors

glEnable(GL_LIGHTING);
gLEnable(GL_COLOR_MATERIAL);
glEnable(GL_TEXtURE_2D);
}
