kandi X-RAY | Ascent Summary
Ascent is a WebGL experiment. The setting is a space simulator. The main goal of Ascent is to create a tool that makes it exceptionally easy to script levels, without having to know anything about WebGL, 3D stuff or anything animation related. The secondary goal is to have a project that is fairly self-explanatory to encourage forking, modifying and extending it. It's a mere skeleton right now, but basic functionality is in place, like adding new levels, pausing the game, a menu, a settings panel, loading models and so on.

QUESTION
Prepare to see some really ugly code.
So essentially what I want to do is create a simple up and down bobbing motion for a 3d object in unity, that gets faster on its descent, and then slows back down on the ascent. The code I have below achieves this effect, but I know there has to be a better, more elegant way of doing it, I just can't find one.

I need your help. I'm currently trying to write a text 2 png library to generate PNGs including inline styling for every single letter. Currently I'm really stuck trying to add a spacing between each letter. At the moment every letter is written like in layers above each one:
Do you have any good ideas how to do this? At the end the letters should be beside each other including the option to pass a letter spacing to modify the spacing later - like line spacing:

Answered 2021-Apr-20 at 17:42I couldn't quite get to the end of your code, since the snippet you contributed is rather comprehensive... But I believe what you're looking for is the measureText()
Method of the canvas context. It returns the width the given String would have, if it were displayed on the canvas; you can read more about that here.
I guess you could use this method to calculate the offsets needed for the different letters. Since measureText()
already considers the font type you won't have to worry about different char widths...

I'm trying to make an svg font for the unicode braille range. I want the black dots to be filled dots in (#fontcolor), and the non-dots to be circular lines.
"⠛" becomes the following svg:
...ANSWER
Answered 2021-Apr-18 at 18:02Here is an example of 'filled' and 'hollow' circle paths:
Outer circle (Clockwise): 'M cx-or,cy A or,or 1 1 1 cx+or,cy A or,or 1 1 1 cx-or,cy'
Inner circle (Counter-clockwise): 'M cx+ir,cy A ir ir 1 1 0 cx-ir,cy A ir,ir 1 1 0 cx+ir,cy'
where cx,cy - center point coordinates, ir - inner radius, or - outer radius
Filled circle is outer only, hollow is a combination of both inner and outer.

Answered 2021-Apr-04 at 23:07I see in the first table the mountain name is 'Tom a' Chòinic' (the accent on o) but in the second table it is 'Tom a' Choinich' (no accent). Since the names are different, it see's it as different records. Try making them the same strings.

QUESTION
I am currently working on debugging some of the DirectWrite code I have written, as I have run into issues when testing with non-English characters. Mostly with getting multiple Unicode characters returning proper indices.
EDIT: After further research, I believe the issue is diacritics, the extra character should be combined somehow. The DWRITE_SHAPING_GLYPH_PROPERTIES
field isDiacritic
does return 1 for the last unicode codepoint. However, it doesn't seem like the shaping process takes these into account at all. GetGlyphPlacements
returns 0's for advance and offset for the diacritic glyph. The LSB is around -5 but that's not enough to offset to the correct position. Does anyone know where in the shaping process DirectWrite is supposed to take diacritics into account and how?
Consider this character: œ̃
It is displayed as one character (through most text editors), but two codepoints: U+0153 U+0303
How do I account for this in GetGlyphs()
, since they are separate codepoints? In my code, it is returning two different indices (177, 1123)
, and one cluster (0, 0)
.
This is what ends up getting rendered:
Which is consistent with both codepoints rendered individually, but not the actual character. The actual indice count returned by GetGlyphs()
is 2.
My questions are as follows:
Should this be returning one indice from
GetGlyphs()
?Should I even be getting one indice, or is there some magic involved with two different indices, where at some stage in the process they are combined in the glyph run?
If I should be getting one indice, what process/functions are these indices combined at? Perhaps a bug in my
ScriptAnalysis
? Trying to narrow down where the issue may be.Should I be using the length of the characters and not include codepoints?
I apologize as I am not super knowledgeable about fonts/Unicode and the inner workings of the whole shaping process.
Here is some of my code for the process I use to get the indices and advances:
...ANSWER
Answered 2021-Mar-13 at 17:56Shaping process is controlled by your input which is (text,font,locale,script,user features). All that affects results you get. To answer your questions specifically:
Should this be returning one indice from GetGlyphs()?
That's mostly defined by your font.
Should I even be getting one indice, or is there some magic involved with two different indices, where at some stage in the process they are combined in the glyph run?
GetGlyphs() operates on single run. Glyphs are free to form a cluster according to shaping rules defined per-script, and according to transformations defined in the font.
If I should be getting one indice, what process/functions are these indices combined at? Perhaps a bug in my ScriptAnalysis? Trying to narrow down where the issue may be.
Basically, if your input arguments are correct, you get what you get as output, you can't really control the core of it. What you can do is to test output for the same text and font on Uniscribe, on CoreText (macos), and on Chromium/Firefox (harfbuzz) to see if they differ.
Should I be using the length of the characters and not include codepoints?
I didn't get this one.
