In Question 2, the disk element doesn't fit the equation of a circle. | |
|
The disk element in the question is identical to the result of the function strel('disk', 4). If you wish you can create your own disk element according to the circle equation. Just make sure it looks like a disk (and not like a cross), and it's consistent. The difference is because strel considers pixelization, and the circle equation is for the continuous case. |
Could you clarify the operations in Question 3, Section A? | |
|
All the operations in this section are relative to the camera axes. Displacement of the image plane means repositioning the center of the plane relative to the camera point of origin. It is NOT a translation of the camera. Remember, when referring to the image plane, it is the one where the image is obtained reflected (relative to the world object). |
Could you clarify a few points in Question 4? | |
|
You can make reasonable assumptions on the scene, but you must write them clearly. The light source in this question is a point source, and the surface illumination is depended on the distance from the source. In section A, you can assume that the image plane in the camera is finite, and that the camera sees only a portion of the tube and the plane surrounding it. In section B, the image plane isn't needed since only the radiance is required. In section C, you may use the Phong model, but it isn't necessary. The tube is NOT a mirror. You may assume that the lens is small relatively to Z0. |
