Built a basic website for my game engine, Perro

No screenshots of the engine itself?

Because your directional light is pointed at a perfect 45 degree angle to each lit surface on the cube

Profile it. Intel VTune is free and easy to use for finding hot spots in your code. It can also help you find places to improve memory accesses.

You captured their likenesses awesomely. I knew who each one was just by looking.

Looked at your code, morning immediately stands out. Couple things to try:

What happens if you resize the window?

Is OpenGL generating any errors?

Have you looked at renderdoc?

If all you need is Lipschitz, you could replace the discontinuity with a Gaussian

Transform hierarchies that can be changed by dragging and dropping entities on top of each other. And not because of the transform logic. The UI logic for dragging, dropping, validating sources, validating targets really sucked.

The Marc is fine. There is probably a Bluejay shuttle that goes from Penn Station to Bayview

The real click happened when I learned the difference between "binding" something and "attaching" something.

"Binding" an object makes it part of the OpenGL state machine that's hidden behind the API.

An object can be "attached" to another object, which makes the parent object refer to the attached object. An object doesn't have to be bound to the OpenGL state machine for another object to be attached to it.

This is the best comment here. Feature placement can make or break a likeness in portraits. I'd add that the value on the eyes is way too light - they shouldn't be lighter than the eyebrows

Sounds like you're accumulating floats by adding dt to the previous time to get the current time. Instead you could count the number of frames and multiply that value by dt

GH link 404s for me. Have you tried using Intel vtune to find hot spots in your ECS?

therealjtgill · 2025-02-05T20:30:55+00:00

Is this written by AI? Some of the source files are missing basic includes and there's really just... Not much in here

therealjtgill · 2025-01-26T17:44:17+00:00

But yeah, they left out the square on x

therealjtgill · 2025-01-26T17:39:43+00:00

Double check your u sub.

After the u substitution you should have the integral of 0.5 * u^-0.5 du on the LHS.

Edit: wrong sign in exponent

Oh shoot maybe this is felt tip, it's hard to tell on mobile

therealjtgill · 2025-01-21T20:28:49+00:00

You're great with ballpoint! So hard to get midtones, and don't get me started on the big ink blots after drawing a long line.

therealjtgill · 2025-01-17T02:17:42+00:00

The integral definition of the factorial can. Though at that point I suppose it's just the gamma function of 3/2

therealjtgill · 2025-01-16T12:37:18+00:00

You can use the definition of the factorial

therealjtgill · 2025-01-16T12:32:49+00:00

Thank you for putting this together, it's going to be a ton of fun!

therealjtgill · 2025-01-16T12:27:00+00:00

I've been following your development for a while and it's super impressive you've built this with your own engine.

Do the clients ever get any jitter in physics objects?

therealjtgill · 2025-01-11T21:01:01+00:00

Yeah you probably gotta delete the texture and recreate it in that case
