Understanding Mathamatics in SL Design?

I have been dabbling with assistance from a friend and it made me wonder with all the educational events, why has there n ever been a Mathamatic event announced?
Would anyone be interested in this?

I would be interested in it. I still don't know what units SL uses for images.

I have no clue either about units. Other then 512 by 512 is best is for most computers video cards. Some basics about sizes of textures. There is something in texture forum about it.
I have discovered certain sizes are better for certain things based on your use of that texture but it was costly lesson.
Just starting to learn coordinates, etc. I have friend who occassional gives me crash courses on mathamatics and uses in SL, including history and how our world is created by triangles. I never finished school so this been very educational and I have always had fascination with mathamatics and design in spite of my education. I wonder if there are others too who are interested in this as a series of events?

FD, go into render options and turn on wire frame. Triangles...lots of triangles...

Also, 512 by 512 is *not* bet for textures. It is almost always the *largest* you need. In many many cases, smaller will work fine.

What do you mean by "units"? Pixels? Inches?

Yeap that what I was referring to about the triangles. My friend said the triangles in rendiering make our virtual world load faster. She was teaching me degrees and math of triangles but we got stuck in radius. LOL
I was told 512 x 512 is best for highest size. First 3 months I was a resident I spent lot of L because I was thinking 1024 x 1024 would make better quality textures but I learned that size causes video card loading problems for most computers and that greyness.

It is dependant on what you are using the textures for, obviously a 1024x1024 texture on a door knob is an incredible waste of resources, but I have seen this done. For wall textures that act in a 'tiled' fashion, use small textures (even 256x256) and set them to repeat, your graphics card will love you for it.

Look out for PNG's coming to SL... 8, 16 and 32 bit versions (I hope) with alpha channels on the 8 bit, like GIF's. Although I fear PNG may only be one way support, i.e. when you save a texture, not upload it, which will be a crying shame.

Remember. When yo upload a texture, it is converted to jpeg2000, no matter what it starts out as. tga, png, jpg, and so on are only relevant on your computer when you are working on them.

Yes I did remeber, hence my quote about it being one way... wont stop me wishing though LOL The PNG is only being used as a substiute for the old BMP option when saving.

I don't even know what png is but I found this transparent auto thing in Adobe but when I save item or try to select it as png everything goes wrong I am trying to learn things many of you probably have already learned at 42 and its very difficult.

Portable Network Graphics (PNG) comes in three guises 8bit (equivilant to a GIF and has index and alpha transparencies), 16bit and 32bit are equivilant to JPG as an overview.
Programmes like Macromedia Fireworks adopted PNG as its native format. I used it extensively on website creation before JPG became the 'norm' and left PNG in it's shadow.

FD Spark > do a search in the texturing tips forum for tutorials on alpha channels...Just using the transparancy (ie. transparent background + eraser on the foreground) won't work... you need to use an alpha channel.

It's quite easy and took me 5 minutes to learn, and I'm not any kind of photoshop whiz or anything.

i started a tutorial for people like you, FD, who love doing this, but don't have the background. Of course, what happened is that I don't really have enough time to work on it.

My new idea is that *you* write it (in the Wiki). i know, you are not an expert. But you do know what you know it, and you know it the way a novice knows it. So, other novices a few weeks behind you would find it very useful.

and then, people who know it a little better will review the work, and, since it is a Wiki, they can improve and clarify it.

Just a thought.

Line factoring and ratios is something I've been thinking about writing about in an SL specific way.

In my profile in picks under sculpted garden I have area that briefly explains cartesian cordinates the graph is slightly off and I misspelled Origins. It explains the rules of cartesian coordinates and the basic graphic system based on private tutorial. I had idea about doing sort of in world tutorial like orientation island on different subjects. So far I have explaination of Rokuro, Cartesian cordinates but I would like to advance this bit better but I am still learning. I have been quite ill so I have reall had time, Thank you for feed back soon as I am feeling better I will follow through on more suggestions. I must confess also the learning curve has been so steep I am burning out majorly.
I also was going to do something on ratios, spheres, triangles and percents but I having to relearn from scratch because of my health and personal condition.
Not everyone who comes into SL has lot of knowledge about these related subjects and I really want to do something that helps those who are creative but bit cheerful like I am or in my designs and not always good with allignment, math and the more advance things once I can again.
