Re: Screenshot of the Month, April 2017 [Submissions Open!]

submissions closed, I've been dead for a while - sorry about that.
For now I'll probably not make next months, we keep getting only one entry which defeats the point - come fall I'll probably start them up again unless someone wants to pick up the torch

Re: The Size of ITexture is too big

The problem with the format is the compression is GL only so we get a feature disparity where the memory usage becomes unpredictable, unless it runtime rebuilds the texture to something supported like S3TC which is probably above and beyond the scope of any reasonable driver, and since it's technica...

Re: How to find out who's owner of an Intellectual Property

Ah yes, S3TC expires soon - which means it might finally become core profile instead of an extension (assuming more OGL revisions, khronos probably won't but w/e vulcan would have the same problem)

Re: The Size of ITexture is too big

RGB8 to DXT5 would be more interesting since GPU can take compressed DXT - for OGL 4.3+ ETC2 format is also available. Another compression scheme that would be interesting to support would be ASTC, any of these with RGBA8 or SRGB (where applicable) is orders of magnitude smaller and supported direct...

Re: Merging JPEGS without recompression

lossless jpegs are typically larger than an equivalent png, and you can't have alpha.

Re: The Size of ITexture is too big

If you want better than that you'd have to use DXT compressed textures or some other compression that the GPU can decode directly (there are a few different ones), I don't think irrlicht supports these directly - I know PNG will get you uncompressed image data in memory.

Re: Merging JPEGS without recompression

jpeg implies lossy compression, it's not a good format to use.
use png or tiff or any other more suitable format (ideally something using DXT compression)

Re: How to find out who's owner of an Intellectual Property

But it has, because patent law is broken - this is why patent trolls are a thing. What does matter is, the patent exists and it restricts you from n-dimensional image synthesis and a few other things, none of the clauses apply to 2 dimensional noise however and using it for 3-dimensional mesh genera...

Re: How to find out who's owner of an Intellectual Property

You cannot copyright or patent an algorithm, they're math. Wrong, you can - and it's done often; that's like saying "you can't copyright or patent language or sentences" in regards to "is book x copyrighted" As for who: Mr. Kenneth Perlin owns it - the (confusingly named[1], sin...

Re: Porting a simple scene from three.js - Where to start

[quote] points, lines, and shapes. [quote] For lines you could draw debugging lines from raycastasts I guess, for points... a very short debug line maybe? Or possibly a billboard texture - as for shapes, if they're 2D just use a texture or construct a 2D polygon from vertices manually and draw that ...

Re: How to make GIFs of your IRrlicht games?

probably easiest is to just capture it with gyazo, there may be dropped frames but gifs are usually somewhat lower framerate anyway so you'd want to drop them anyway or they'd run awfully on lower power machines. Maybe gyazo even has an API for proper integration, who knows... well actually I do, it...

Re: What is happening when an .irr scene file is loading?

I can't really show you code for that as the implementation is flaky (I wish to stay polite), so I'll leave it as an exercise to the reader. I'm still not convinced this is a good way of using Irrlicht. You'd be correct, it's not a good way the way irrlicht is written - if I ever finish my thread-s...

Re: What is happening when an .irr scene file is loading?

You can't create a device when you already have a device, and you can't refresh the screen when still loading files, only between loading - if you want that you might want a 3rd party library like assimp (note: getting it to play nicely with irrlicht is an entirely unrelated question). The easiest w...

Re: What is happening when an .irr scene file is loading?

there is insufficient code to determine why the beginScene() command failed.
MartinVee's suggestion is probably the cause if I'd have to guess though.

Re: Website hacked? :(

I saw google ads there so for a moment I was about to say "well there it is, ad code - of course that won't be in my version of the page since it gets stripped" but then you pointed out it's from your adblocker so that makes a bit more sense to me now.
