Step 2: - Adjust camera rotation and position to match that of the image :
Using your layout Grid as a guide, try to line the elements in your background image with the lines of the grid in the “camera view” window
Try to keep to real world measures; my grid is set to 1m and my camera is positioned in such a way so that the things I judge to be 1 metre away in the image are 1 grid square away in LW - Fig.03

Step 3: - Adding geometry to the scene and surfacing the ground plane :
For this project, I will be adding a simple primitive object onto the right side of the image. In order to achieve the level of realism I am looking for, I need to add a ground plane which will catch the shadow of my object. I made a simple 1 poly ground plane and brought this into my scene. It was then rotated and moved and aligned with my camera grid lines to match the existing elements in the photo - Fig.04

In order to match the surfacing of the ground plane to that of our photo we need to use a technique called “front projection mapping”. This will allow whatever part of our image that the ground plane covers to be displayed on it’s surface, enabling seamless integration of the 2 elements.
In order to do this, open your surface editor and choose the colour channel of the ground object and set the layer to “image map”, the projection to “front” and the image to your background image - Fig.05.jpg
