Thread: HUD text with shader background

No, the z-index is related to but not the same as the height/depth dimension. I'm sure they've used the 'z' in its name to invoke this link in people's minds but it's not entirely correct.

There are only two dimensions because we're talking about 2D graphics here. The z-index defines the order in which these graphics are drawn. The greater the index, the later the element will be drawn and may thus be drawn over previously drawn elements. So elements can be 'stacked' upon one another giving the impression of depth. Hence why it's commonly referred to as the 'stack order'. The main difference is that the z-index uses arbitrary priorities (including negative numbers) while huddraw indices also function as the identifiers for each element.

In 3D graphics, we can place each element in a three-dimensional world so height/depth of each element is defined but when it comes to drawing, it is a matter of perspective (i.e. where are we standing and where are we looking at). This perspective is the field of view, represented by the viewing frustrum. It is typically shaped as a rectangular pyramid with its top and bottom cut off by two parallel planes (i.e. a frustrum of this pyramid).

These terms refer to completely different things. The planes that cut the view direction perpendicularly are called the near plane and far plane. Objects closer to the camera than the near plane or objects beyond the far plane are not drawn.

This guy is the one you go to if you actually want to LEARN how to do something and not just be given the code to do it. He not only shows you how to do something, he tells you why, which is the only way people will actually learn.

If you actually read and understand what he is saying, you can see how they are related to the questions being asked,
Ryback asks why the indices have to be in a certain order - Sor made the comparison to CSS to try and help people understand.
AncientOrder made a statement about the z axis, which is when Sor went on to explain about it in relation to mohaa.

So basically if you dont want to learn anything and just want pre-built code for your mods to work, then go to google.com , if you would rather learn how to do it yourself, then you can come here and ask for help on the forum. We are all here to HELP you, not DO IT FOR YOU.

I know I've always learned something when Sor answers a question for me, I may not remember it the next week but I can always go back to post to re-read it. I have 5 posts book marked so I don't have to search every time I forget...lol
