circles are a lot harder. you either have to draw lots of small triangles, draw a circle texture, or do what I do which is to use an SDF which is a whole nother thing entirely

AAqua circles are a lot harder. you either have to draw lots of small triangles, draw ...

could i make a program that basically creates an empty array and then goes along bit by bit by the circumference of the circle until it makes a full circle and comes back to the start

fornite•4/3/23, 12:51 PM

and with each iteration it stores that coordinate into the array and then uses that as a buffer

AquaOP•4/3/23, 12:52 PM

you have to make sure it creates triangles

AquaOP•4/3/23, 12:52 PM

generally for that i'd use a triangulation algorithm. but i don't know, i never even bothered doing that, I just use SDFs

AquaOP•4/3/23, 12:52 PM

the easiest thing to do though is almost certainly going to be to create a texture CPU side and then draw it

AquaOP•4/3/23, 12:52 PM

won't be particularly fast but the other two ways are vastly more complicated

fornite•4/3/23, 12:56 PM

ah shit

fornite•4/3/23, 12:56 PM

on that note

fornite•4/3/23, 12:56 PM

moving on to drawing textures

AquaOP•4/3/23, 12:57 PM

https://github.com/skyebird189/Silk.NET/blob/samples-textures/examples/CSharp/OpenGL%20Tutorials/Tutorial%201.3%20-%20Textures/Program.cs take a look at my fork, I've written a texture tutorial that doesn't use the GL abstractions

AAqua <https://github.com/skyebird189/Silk.NET/blob/samples-textures/examples/CSharp/O...

fornite•4/3/23, 12:59 PM

theres a way to use gl abstractions????

fornite•4/3/23, 12:59 PM

AquaOP•4/3/23, 1:00 PM

well yes
i myself have written an abstraction layer over both GL and directx, but that is separate to these tutorials
but all the abstractions in these tutorials do is reduce some of the boilerplate, you still have to write the GL stuff yourself

fornite•4/3/23, 1:02 PM

so what should i do

fornite•4/3/23, 1:02 PM

with or without abstractions

AquaOP•4/3/23, 1:03 PM

i've adjusted the tutorials so it teaches you textures first and then does the abstractions and that's the way i'd personally advise learning it

fornite•4/3/23, 1:03 PM

wait

fornite•4/3/23, 1:04 PM

textures

fornite•4/3/23, 1:04 PM

also need a vbo and ebo and all that?

AquaOP•4/3/23, 1:04 PM

fornite•4/3/23, 1:04 PM

can i use the same ones

AquaOP•4/3/23, 1:04 PM

i'd suggest taking a look at the tutorial it explains basically everything that needs to be added and changed

AAqua no

fornite•4/3/23, 1:04 PM

how come in the one you sent youre making vbos and stuff

fornite•4/3/23, 1:04 PM

and the vao

AquaOP•4/3/23, 1:05 PM

because it's an extension to the "drawing a quad" tutorial you see on the website

AquaOP•4/3/23, 1:05 PM

so it still contains all the code from it

AquaOP•4/3/23, 1:05 PM

the bits that are heavily commented are the new bits

fornite•4/3/23, 1:05 PM

okay ill take a look

fornite•4/3/23, 1:05 PM

is there a version wihtout the quad part

fornite•4/3/23, 1:05 PM

to like keep it cleaner

AquaOP•4/3/23, 1:06 PM

errrmmmm i mean yes, my abstraction layer has one, but i wouldn't say it's clean

fornite•4/3/23, 1:06 PM

ahhhhhhh

fornite•4/3/23, 1:08 PM

do i need to install another package

fornite•4/3/23, 1:08 PM

called

fornite•4/3/23, 1:09 PM

StbImageSharp

AquaOP•4/3/23, 1:09 PM

yep

fornite•4/3/23, 1:10 PM

man

fornite•4/3/23, 1:10 PM

i keep getting confused between what is part of the quad tutorial and whats part of the texture tutorial

fornite•4/3/23, 2:05 PM

where are the tutorials for keyboard and mouse input

fornite•4/3/23, 2:36 PM

also how come when i fullscreen the window the position changes

fornite•4/3/23, 2:37 PM

or maximize it

fornite•4/3/23, 2:37 PM

its like wonky

fornite•4/3/23, 2:38 PM

if i draw a shape here thats how it looks

fornite•4/3/23, 2:38 PM

when i maximize it

fornite•4/3/23, 2:38 PM

fornite•4/3/23, 2:38 PM

same thing happens if its fullscreen

chairclr•4/3/23, 2:39 PM

you probably arent resizing your viewport*

AquaOP•4/3/23, 2:39 PM

in opengl there is no backbuffer to resize. instead you must change the viewport

fornite•4/3/23, 2:41 PM

how do i resize the viewport

circles are a lot harder. you either have to draw lots of small triangles, draw a circle texture, or
