What I did today

Miscellaneous Topics
#1261

I spent today working with more updated opengl.

What I learned:

  • OpenGL 3.0 vertex buffer objects
  • OpenGL 3.0 textures (just mipmaps)
  • All about the projection, view, and model matrices
  • How translation, rotation, and scaling works under the hood
  • Applying translations/rotations/scaling with shaders
  • Basic uses of shaders
  • How orthographic projection (glOrtho) works under the hood

All in all I am just developing a better understanding of OpenGL and having fun doing so :slight_smile:

#1262

Nice work! Are you programming it with c++, Java, or…?

#1263

LWJGL, so Java (and C/C++ if you want to get technical)

#1264

Bringing back an old project of mine and making it better (also isn’t in Java ;)).

Today I got dug in to doing some GLSL programming and finally learning how to use them properly .
I built a small glow shader , not Gaussian yet , mainly box filter but I am going to introduce that soon. I also created a shine , it’s a linear form of the glow shader with a larger kernel length.
Here is a demo from a background I think it works well , what do you think?

#1266

I programmed a quick python script to ping a range of IPv4 addresses and, if they responded, use a database to get their coordinates. Then I simply transformed the lat/lon to unsigned coordinates and plotted it on an image. Got a pretty neat output:

Now I’m going to implement it in Java in my 3D engine and, with some additive blending, make a nice and fancy rotating sphere of part of the Internet.
Edit: Notice North Korea is completely dark.

Edit 2: Additive blending and a much higher resolution. I’m going to do the 3D stuff when I get home because I don’t have my engine code on my laptop. Happy Holidays and happy New Years everyone!

I created a health bar and made my ninja climb a tree :smiley:

Nice looking game. Is there a WIP thread for this?

#1269

Thanks

No, it isn’t java related

#1270

The cel shading reminds me of Zelda Wind Waker, nice job!

#1271

You are the second person who said me that today :smiley:

#1272

Did you base the art off of that game, because the water is similar. Also is there somewhere where we can see more pics or demos or something? Seems interesting.

#1273

I have never seen that game until today so the answer is no.
When i finish the things in my TODO list i will launch a demo. Until that i will show here and in my twitter

#1274

I got a heightmap system in libecu working.

714×504 3.09 MB

The classes themselves don’t have a lib-ecu dependancy anywere either. Plus, libecu is released on the public domain. So use however you want!

And a use case: ( the gif you seen )

#1275

Played with Blender and my renderer a bit more, got this weird looking thing.

Huzzah finally got down to finish the movement code , it was slightly annoying because of the fact it required calculation of the rotation of an object with moving parts , but its sorted ill post a picture of it soon I just need to implement the actual rotation of the sprite and movement within the defined space. The only annoying thing after that is calculating mouse collision on a rotated area but I think I have figured that out. I hope.

#1277

Rewritten my personal game lib to use LWJGL3. Changed input management from JInput to GLFW.
Now the awesomeness can continue ;D

Did a lot of experimenting with lighting.

It was a pain in the ass, but still incredibly fun to do. :slight_smile:

UGh i’m still stuck on trying to implement correct movement when given a COT and COM , I have all of that figured out but the trig is just going straight out me head.
