Texture mapping

[Travis Cobbs]

Ok this is too technical for me 

What would be the ideal dimensions for the PNG?
Would 1768x879 be it for a 1x4 brick to have a good enough resolution, a good fit and good result?

I am aiming to create some standard parts that are typically patterned like the 1x1, 1x2, 1x3, 1x4 ,1x6 bricks etc.
And tiles 1x1 (square or round), 1x2, 2x2, 1x3, 1x4, 2x4 etc.
And thus create some template PNG files of the correct dimension so we can easily create new patterns.
The minifig torso is a good candidate too to create some standard as are panels.

Unfortunately, there's no one right answer, since parts can be used in arbitrary ways and rendered at arbitrary sizes. Having said that, old graphics hardware might fail to load any textures that are bigger than 2048 in either dimension. So it might be good to keep the textures smaller than that*. 2000x600 would probably be plenty to represent the entire area of a 1x4 brick. The trick is that for an official part, the texture should be auto-cropped, and the auto-cropped texture should then be mapped to fill the appropriate region of whatever it's being applied to.

* Technically, renderers (like LDView) should detect the hardware's maximum texture size and automatically down-scale textures that are bigger than that. I can't remember if LDView does this or not, but I think not. It's something I'll consider adding if it's not already done.
