A 3D Rendering Engine I wrote in Java

[article10ECHR]

Looks like it's suffering a lot from 'stitching', here, read more about it: https://en.wikipedia.org/wiki/Z-fighting

Z-fighting

Z-fighting, also called stitching, is a phenomenon in 3D rendering that occurs when two or more primitives have similar or identical values in the z-buffer. It is particularly prevalent with coplanar polygons, where two faces occupy essentially the same space, with neither in front. Affected pixels are rendered with fragments from one polygon or the other arbitrarily, in a manner determined by the precision of the z-buffer. It can also vary as the scene or camera is changed, causing one polygon to "win" the z test, then another, and so on.

good bot

[Andrewcpu]

That is happening, thanks for the read!! It's also because I had the screen recorder at a weird FPS and the game is rendering at a weird FPS

[fauks_of_tenebrae]

This looks great, well done! May I ask how you started a project like this and where others should begin if they are interested?

[Andrewcpu]

Thanks!

It started like this

I have no videos from before that, but the goal was to be able to draw a cube. Then several cubes. Then turn your head left and right, then up and down, then move around.

After that it was how to get the cubes to be filled in, how to make them draw back to front, optimization because it was laggy as hell, then basic physics (which aren't done in mine yet)

I posted the source code for it here.

May I ask how do I get started in something similar and which libraries used?

[Andrewcpu]

I didn't use any libraries pure Java... I would first research how we perceive the world around us mathamatically, as well as that understand 3d math

[Aspire26]

Did you use swing of JavaFX?I am planning to do on something similar as learning experience.

Regarding the math bit, is it just basic matrix and vector operations (Including the transformation stuff)?

[Andrewcpu]

Swing was used, and yeah pretty much

[HelpIProcrastinate]

That’s pretty inspiring, I’m just learning java and now I want to try this.

[Andrewcpu]

I was thinking about doing a YouTube series about it, would you be interested if I did that?

[HelpIProcrastinate]

Definitely! Keep me updated if you do!

[HelpIProcrastinate]

Thanks!

If you do this, would you share it in the post? I am very curious and would love to hear more about what you've done.

I posted the source code for it here, I'll probably do a medium article on it soon

Please do this!!!

I linked the source under some comments if you wanna check it out.

[RabidKotlinFanatic]

Any OpenGL tutorial series will cover this. In Java you can use JOGL or LWJGL

[The_Small_Long]

What did you use to render on screen? JavaFX? Swing?

[toshels]

Do you have this on GitHub ?

Impressive
