This short post by Defold people about "empty project build size" comparison between Defold, Unity and Godot (twitter, mastodon) sparked my interest.

It is curious that Godot builds seem to be larger than Unity? Would not have expected that! Anyway.

A way more extensive Unity "web" build comparison and analysics is over at https://github.com/JohannesDeml/UnityWebGL-LoadingTest but here are just my short notes in trying out Unity 6 (6.0.23 - Oct 2024).

Default (3D, URP) template

Example of how to capture CPU counters with ETW on Windows, perf on Linux or kperf on Apple.

Using ETW needs somewhat recently updated Windows 10 or 11. Not sure about exact version.

Currently tested on:

This is a short post related to Opaque object representations from Our Machinery. I have to begin that my understanding of how Our Machineries tech is somewhat limit and it is currently rather late in the day, so please bear with me. As far as I understood how modules work is similar to how Quake 2 did their modules. A module has both a struct for export and one for import containing a number of function pointer. At load time the module gets a filled out import struct and fills out its own export struct with its own functions and returns it.

As for the allocators. I would have guessed tha

These affect the calling scene only.

Example:

this.scene.start()

	double delta_time_filtered(double dt_nanos){
	// Warm start the filter by assuming 60 Hz.
	static double x[] = {1.6e7, 1.6e7, 1.6e7}, y[] = {1.6e7, 1.6e7, 1.6e7};
	// IIR filter coefficients. 2rd order lowpass butterworth at 1/128 the sample rate.
	static const double b[] = {6.321391700454014e-5, 0.00012642783400908025, 6.321391700454014e-5};
	static const double a[] = {1.0, -1.9681971279272976, 0.9684499835953156};

	// Apply IIR filter coefficients.
	double value = b[0]*dt_nanos;
	for(uint i = 2; i > 0; i--){

	Setup:
	1. Index buffer containing N quads (each 2 triangles), where N is the max amount of spheres. Repeating pattern of {0,1,2,1,3,2} + K*4.
	2. No vertex buffer.

	Render N*2 triangles, where N is the number of spheres you have.

	Vertex shader:
	1. Sphere index = N/4 (N = SV_VertexId)
	2. Quad coord: Q = float2(N%2, (N%4)/2) * 2.0 - 1.0
	3. Transform sphere center -> pos

	This is based on instructions by @Capn_Andy (apparently now @SnugglePilot), who was
	pointed there by @Chaklapak. I implemented this the first time April 17, 2016, with
	some updates to make it work for Early Access (the original version gave me just the
	"Early Access Review" as review text). This version here is an update from April 30, 2017
	which was long overdue because my previous RegEx-statement mixed things up quite a bit,
	probably due to Steam changing the format a while back, resulting in the same reviews
	popping up in the Slack channel over and over, with authors, recommended / not recommended
	and the actual reviews all mixed up.
