Particle Swarm (WebGL + Geometry Buffers + GPU Noise)

Just a whole bunch of particles being rendered through geometry buffers (and modified on the GPU); also working on some better GPU-accelerated noise.

Created September 22, 2017 15:04 — forked from quixeltools/Megascans Bridge API.md

#Quixel Megascans Bridge API ####Updated: Aug 19th, 2016

We have developed an API to fetch information from the Bridge. The following is an initial list of endpoints any software will be able to retrieve information from.

Megascans repository path
Zip folder paths
Get all assets (folder and json path)
Get selected assets (folder and json path)
Search results (folder and json path) against a string

Enumerations in Unreal Engine 4

	// Generally, developers in UE4 tend towards the following convention for enumerations:
	UENUM( BlueprintType )
	enum class ENoiseGeneratorCellularType : uint8

	NGCT_Natural UMETA( DisplayName = "Natural" ),
	NGCT_Euclidean UMETA( DisplayName = "Euclidean" ),

Last active August 4, 2024 09:42

The "Fun" to be had (i.e. a big rant) in writing a general-purpose physical movement component (compound colliders representing static and skeletal meshes and more, but still interacting with the world as a physical entity). NOTE: All comments in this gist are by me.

	// Comments are left by me, not from the code.

	// Because why not have a default set or make the method abstract or, really, anything but this. Luckily no one would ever
	// think to use ::GetMaxSpeed as a divisor or anything.
	inline float UMovementComponent::GetMaxSpeed() const
	{
	return 0.f;
	}

	// FUN FACT: UMovementComponent defines a plethora of methods for managing the maximum speed of a component. It does not,
