I like the one proposed by the thread starter(thread starter is better than me butchering your handle)…the others a just as noisy as the one currently implemented…and the black and white one can get confusing with just the 2 colors, it lacks relative readability, not to be rude(I hope).
Doesn’t a UV test grid need to be scalable? Other than the difficulty of writing the generator code for multiple resolutions, I think this one would be much better (thread starter ) Other one is not bad if it was in color, but still less clear. Of course, there could be a choice…
I definitely agree with Oxben on that. The value of the letter may also follow a gradient from white to black in order to be the inverse of the value of the colored squares. Also, I see this as being procedural. With letters, after Z you go to AA, then AAA if needed etc (doubtful it’d need to go past ZZ99). And the colors and values could cycle as resolution ramps up. Alternatively, the colors could stay fixed, and the scale of the underlaying grid would decrease, and the amount of total squares would increase.
I’m glad that you like it I wrote that I believe this grid is easy to generate I program a little but I’m not good enough to write generator. Here is the algorithm according to which the grid might be generated :
Color hues change every 45 degrees in every column
chessboards are (black and white) 1,2,8,32 px (it depends on image resolution)
size of white grid depends on biggest chessboard (div/4 or more)
the vertical gradient (from white to black) is put on top of it
two (white with blur and black) letter grids are generated so as to fit in the biggest chessboard
everything blends together but each layer has different opacity percentage
if somebody wants to have grid like 324x432 we may generate 512x512 image and cut it to lower resolution
I haven’t thought about generating higher resolutions than 1024px, but maybe Dim advices are good everything depends on the developers, they will be implementing it
Whilst the image that szczuro posted is well done, for me, i think its just too colourful for long periods of use. :S
The whole point of the UV grid image is to check for stretching and island orientation and i think with colourful gradients it would make this job harder as really everything needs to be uniform.
Plain old black and white is easy on the eye and errors can bee seen quickly…i tend to use a black and white checker that is numbered 1-0 with the text being the opposite colour than the square it is placed upon.
This is one of the most pointless things to happen in autodom. ok that was an overstatement, but why does BMW need a 0 series. They have Mini, so why are they gonna make a vehicle that will compete with their own Mini?
Dude, you use a font and some basic colour images. The software just cut/pastes them into position, and BLAM! There’s your grid, at any resolution. They’re just letters, any programmer worth his salt could easily make this procedural.
PS: I’m using this test grid for my own unwraps, is that okay?
