Small rectification: The article was written by Jermie and the picture where provided by cenotaphe, original idea is from both of them.

And I don't think it is meant to have any specifique use, just an interesting fact ...

I think this might've been better off as a thread, as, in your own words, you're not sure it has a specific use!! I don't understand the maths LANGUAGE you use, but I understand the meaning - if you're planning on having this as an informative article I think you need to decipher the Maths patois for those less versed in Cosines and tangents

 

[snapple]

An interesting fact....thats not what articles are for. They're to help and give USEFUL information. I hate To give it such a low score, but i can't see the use of it, despite that barley anyone can get the jist of what your saying.

 

[Lord Warrior]

Well, this is interesting fact, especially for Electric engineer like me, but I realy do not want to bother wit math while painting.

answer from jermie : Article done for fun but it's a good way to understand zenithal lighting, some humour may be required ...

 

[Ogrebane]

So I guess this can be used if there are two surfaces to work out how much light will be rflected onto each surface. Might be fun to have a go at it. Nice tute thanx

 

[yack]

wow, you must really have a lot of time on ur hands to work somethin like this out, and i really do not wanna do equations while painting- its supposed 2 b fun remember

 

[AinuLainour]

*yack - the point of this article is for people who want to paint well, for competition. It obviously isn't taking the fun out of it for many of us.

 

[frenchkid]

heuuu no, the article is not for people who want to paint for copetition. It's a joke !!

 

[Frank Battaglia]

Unfortunately, it's also incorrect. The light reflected off of a diffuse surface by a single source is proportional to the cosine of the angle between the surface and the light, not 1/tan.

 

[samwisethegreat]

It's logical to figure that the higher areas are lighter. You dont need a mathematical formula to work it out.

Painting minis aint math

 

[crossfit]

This is awesome. I love it. I don't understand the math but seeing the gradients in this context is very helpful.

 

[Ghaffasa]

an incorrect and a completely pointless article

 

[A Luna]

a 10 to annoy other people
but this is what happens if you havent got humour... relax and laugh some more

interesting article though

 

[Harok]

Hah! XD

 

[Yogimu]

interesting concept but if you just shine a light on your miniature and observe the highlights and shadows then you don't need to have your calculator and a teeny tiny tape measure to hand. Still, useful for the less observant among us I guess.

 

[supersimplerenji]

interesting idea, but takes too long. Better to just grab a solid object and use a lamp to aim it at which position u like. I prefer to be time over calculation.

 

[JojoTheFlamingMonkey]

Yep, that'll do. I think perhaps you would have been better off using surface normals and vectors, and comparing the vector made by the surface normal to the vector made by the direction of the light hitting said surface. No math involved and intensity can be guessed by comparing the directions of the two vectors (arrows). It's a visual method that's pretty immediately understood so long as some simple definitions are taken care of first.
