Drawing & aligning textures & view

I need help :(.

I’m trying to draw multiple textures, align them together & draw a decent view. The textures themselves are like rectangle prism (ie 3D like);

With different fixed widths, but with variable heights. The edges of the prism need to align to others along pink left & pink bottom/right face.

*Following is extract of what I’m currently using following;


	glClearColor(1, 1, 1, 1);
	glDisable(GL_DEPTH_TEST);
	glDepthMask(GL_TRUE);
	glColor4f(1.0f, 1.0f, 1.0f, 1.0f);
	glEnable(GL_TEXTURE_2D);
	glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

LoadTextures()
{
		glBindTexture(GL_TEXTURE_2D, pGLUINT[iItem]);
		glTexImage2D(GL_TEXTURE_2D, 0, 4, Imgwidth, Imgheight, 0, GL_RGBA, GL_UNSIGNED_BYTE, Imgrgba);
		glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
		glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
		glEnable(GL_TEXTURE_2D);
}

void DrawScene()
{
	CRect rWnd;
	GetClientRect(&rWnd);
	glViewport(0,0,rWnd.Width(),rWnd.Height());

	glMatrixMode(GL_PROJECTION);		
	glLoadIdentity();					      

	glOrtho(-20, 80, -20, 60, -1, 1);

	glMatrixMode(GL_MODELVIEW); 
	glLoadIdentity();

	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
	glLoadIdentity();						

	glTranslatef(-14.50, 14.5f, 0.0f);

	DrawPrisms();
}

void DrawPrisms()
{
	std::list<Textures>::iterator itText = m_Textures.begin();
	for (; itText != m_Textures.end(); ++itText)
	{
		//subsequent textures need to align with previous one.

		glPushMatrix();

		const float Prism = itText->mSize;
		
		float fL = itText->LocX;
		float fR = fL + Prism;

		float fB = itText->LocY;
		float fT = fB + Prism;

		fT = fT * -1;
		fB = fB * -1;

		glBindTexture(GL_TEXTURE_2D, itText->mNum);
		glEnable(GL_BLEND);
		glBegin(GL_QUADS);

		glTexCoord2f(0, 0);//TL
		glVertex3f(fL, fT, 0);
		glTexCoord2f(0, 1);//BL
		glVertex3f(fL, fB, 0);
		glTexCoord2f(1, 1);//BR
		glVertex3f(fR, fB, 0);
		glTexCoord2f(1, 0);//TR
		glVertex3f(fR, fT, 0);
		glEnd();

		glPopMatrix();
	}
}

Main problems I’m having;
-aligning textures together properly.
-texture overlapping.

Would appreciate any help :).
Thank you.

ps I understand this is depreciated code.

Well managed to mostly sort my problem;

-aligning textures together properly.
It’s not perfect, but I’ve had to do something along lines of;

				pImage->fLeft = (((pImage->TileX) * fImgWidth) - fAdjustX)) - (((pImage->TileY * fImgWidth) - pImage->TileY*fAdjustX));
				pImage->fTop = (((pImage->TileY) * fImgHeight) - fAdjustY)) + (((pImage->TileX*fImgHeight) - pImage->TileX*fAdjustY));

-texture overlapping.
Sorted mostly by utilising z order as follows;

		glTexCoord2f(0, 0);//TL
		glVertex3f(fL, fT, -0.75);
		glTexCoord2f(0, 1);//BL
		glVertex3f(fL, fB, 1.00);
		glTexCoord2f(1, 1);//BR
		glVertex3f(fR, fB, 0.75);
		glTexCoord2f(1, 0);//TR
		glVertex3f(fR, fT, -1.00);
