How to Make a Simple 3D Modeling Program | OpenGL Tutorial

[@Cyranek]

I've never seen a more niche youtube channel that feels like it was made just for me.

[@Atomhaz]

seriously I was just thinking this!

[@makkerfelix]

what are you doing here

[@erik9817]

And me, except I was experimenting with Direct3D.

[@joho0707]

how did you get here

[@farhanahaque4057]

You are an unexpected guest

[@gavinlew8273]

Awesome tutorial, KZbin needs more tutorials like this. Guides on creating 3D models are plentiful .. not so much on creating 3D Modelling Programs. Great job!

[@3DSage]

I will be making a better more advanced tutorial soon so keep watching :)

[@pajeetsingh]

Subscribed. I am making myself but finding it hard to think about? Is it something in this line of thinking?: Take user's cursor locations;cursor path etc, write to GL_COPY_WRITE_BUFFER buffer object in GPU RAM, draw on screen the primitives that fills the paths, write back to CPU RAM using GL_COPY_READ_BUFFER?

[@zooidiotgaming5784]

Can you make the second part because i want to make this but with camera movement and stuff thats in like blender like moving vertices or edges and stuff like that or maybe let the user see the vertex normal and stuff PLEASE make the second part

[@zooidiotgaming5784]

@Nem Gam Boi i cant idk how to code and his tuts are the only thing thats teaching me how to code and also i tried to download devc++, which is the IDE that 3d sage uses but failed. Theres a BIG probabylity that its not his fault so it just my laptop's fault

[@zooidiotgaming5784]

@Nem Gam Boi listen my friend i know im bad at it , ive been trying to learn how to code for about 4 years since i was 11 y/o im currently 15 y/o (in this year 2021 that is) and im just overall dumb and yes i know im lazy that is also why i cant do it, i have however found a solution on how to code , you see im currently am learning web development ive done some HTML and CSS, so im learning javascript which IS a programming language even if it have some limitation So dude Just dont judge a book by it cover

[@phyllisginger1147]

Excellent tutorial. I believe very strongly that tutorials should be kept as basic as possible. You did this very well. You get a lot done in reasonable amount of time, without going too fast. Also you don't get bogged down in programming issues. Question - shouldn't GLUT_DEPTH be included in the glutInitDisplayMode call? Suggestion - move the calls to glLineWidth and glColor3f out of the loop in the draw_Grid routine. Those calls do not have to be repeated for each line drawn.

[@3DSage]

+Phyllis Ginger true, I agree with your suggestions. Thank you for your comment. I'm glad to hear that people like it and can learn from it.

for some reason i cant see the grid when the glTranslatef(-13,0,-45) but if i do say (-13,0,4) i can see like 4 peices that are huge

[@user-mx2wq4zv4m]

Guys, don't forget to add "init();" before "glutMainLoop();" in "main" function. I experimented with parameters for 30 minutes, then continued watching the video and discovered it.

[@iceman2131]

Огромное спасибо!

[@Rogo183]

your video is very helpful, especially the "What to do list". Help us understand what function we need.

[@3DSage]

Thank you. I personally make a list before every program I make. It always helps me so glad it helped you too.

[@tails_the_god]

So a matrix is what makes a group of vertices,faces, and edge's into a model object?

[@AntonioAstorino]

Hi! Beautiful tutorial. "Unfortunately," modern OpenGL requires the use of vertex array/buffer objects (as far as I understand). It would be amazing if you could make a similar tutorial in modern OpenGL.

[@3DSage]

Yes that would be a good idea.

[@abdelhaksaouli8802]

just use GL_DRAW_DYNAMIC and write function that insert and remove point to your buffer, and rearrange your index buffer

[@colepeterson5392]

Is this method outdated? Should I learn modern openGL with GLSL? This is by far the best damn tut iv'e seen. very straight forward.

If we want to delete a quad , how to do it ? What code we need to use?

[@3DSage]

Rachita Rd Since each quad is stored in an array, you cycle through all the array elements and stop on the one you want deleted, and transfer the data of all the following array elements back one. And subtract one from the total amount. There should be some good help online about removing an element from an array. I'm glad you are adding to the program. Good luck!

[@syntaxed2]

Dont use GLUT - Its rather old, un-maintained. GLFW is a better choice, theres also SDL. Also, the openGL commands used in this video are deprecated/obsolete, they are like 2003 standard - Its called the fixed pipeline and only exists for backwards compatibility.
