Title: The Art Of Shadows (inspired from M.C.Escher)
Name: Najeeb El-Fatih
Country: Comoros
Software: 3ds max, finalRender, Photoshop, ZBrush

This imaginary work is inspired from M.C.Escher's (1898-1972) optical illusions and impossible constructions artworks.. The main idea is focused on an object that has three different shadows depending on the light angle. It casts shadows of the three creatures: knight, horse and eagle. I use it twice . The first one enclosed inside the lantern and you can see its triple shadows casting on the lantern sides. I put it also below the lantern to cast two different shadows on the wall as you can see . Also there are some interesting classic impossible shapes.


The wire frame of the tri-shadow object(Click to enlarge):

And this is animated version of the same tri-shadow object rotated to let you see the shadows more clearly:

The left side horse object has 2 different shapes can be seen from different angles. You can watch this animated rotated version of the horse:

I hope you enjoy it.

Well done! The objects you made are really impressive. I'd love to see a rotating version of the two impossible shapes though :D.

Although well executed as far as the modeling is concerned, the rendering really lets down. The image looks boringly orange and only after reading your post is it clear that something strange is going on with the objects. With good presentation this could be a ***** piece, but the way it is now, it only gets *** from me...

Thank you Chuppa.
I am planning to write short tutorial about making all details presented here. I think the tutorial will be more interesting. This work is more science related than CG. :)
The orange look (hot and dark) to give the audience more attention about the magical feeling and the strange shadows behavior.
Best regards.

This is the wire frame of the impossible objects (don't laugh :) ):

There are a lot of approaches to fake the impossible objects but I choose the most believable one IMHO.

Hey man, I like it a lot!

Extremely good work on the main shadow casting model... I wonder how complicated it was to think about the shape.

I think it would be extremely cool, so to speak, to see a movie of a candles casting each shadow... flickering a bit :thumbsup:
I agree that the render seems just a bit dull... but also relaxing.
Nicely done...

As I promissed this is short tutorial about steps to make tri-shadow object:

Planning
Before we begin the modeling process you should consider some necessary points to make optimal tri-shadows object. Note that not every three objects can fit together and make fine object. Careful planning will give you nice result. These are the main guidelines you should consider:
1- Concave shapes are not suitable in all situations but convex ones and semi convex will produce nice results with little tweaking and will make your life easier.

2- Shapes with many holes can distort the final result and force you to make heavy manual mesh editing.

3- Every 2 adjacent shapes has one shared edge. you should make every 2 objects equal in either the width or height (depends on the shared edge).

4- Make the vertices as minimum as possible because the result will produce high polygons count.

5- ProBoolean extension or the former Npower Power Boolean are highly recommended.

Modeling steps
1- draw your shapes with line and spline drawing tools.
2- Optimize the shapes by removing unnecessary vertices and welding the adjacent vertices together.
3- Scale them as necessary so give every 2 shapes same width or height(depends on the shared edge between them) .This will be easier if plan your shape carefully.
4- Add standard 3D studio MAX extrude modifier. Set the extrusion depth to suitable value.
5- Rotate your objects to the desired direction. The angle snap will be handy.
Note: Every object should perpendicular to one of the axis (x,y,z).
6- Move the objects and align them so they should overlap each other.
7- Scale them as necessary and make sure they are fully intersect with each other from the different views of 3d studio max.
8- Go to compound objects and select ProBoolean.
9- Set the operation to intersection and start picking the other objects.
10- Notice the model from the different views to observe any wrong hole resulted from failed Boolean parts.
11- Right click the model and convert it to editable poly.
12- Goto to modify rollout and select vertex subobject.Adjust the vertices position to cover any undesired hole in your model.
13- Make three lights. Everyone should be exactly perpendicular to one of the model sides.
14- Make three surfaces in the opposite direction of the lights to receive shadows.
15- Hit render and you are done,


i hope it is clear.
