Stripping unnecessary data from C++ data structures before sending to GPU
I've recently been working on a particle system in my renderer and I've encountered a situation where my particle class on the C++ side has data I need to maintain my particle on that end, but that I ...

Performance of particle implementation
I am about to implement the renderer for a simple particle system. Every particle has to be updated every frame (position, rotation, scale) and so I was wondering which way is usually faster:

Represent shape as particles
Input: Triangles which make up an arbitrary shape. Each triangle is represented by 3 3D points.
Output: A set of particles which fills up the inside of the object (see image).
I have read the ...

Vertex positions from particle position
I have a question about Nvidia Flex or any particle based simulation in general:
The particles are created by sampling the mesh, which can result in fewer particles than there are vertices in the ...

How to model braids?
Many hair simulations render their hair as lines (usually splines). Since hair is a really thin object.
if the hair is braided, rather than having thin infinitesimally small cylinders, you have ...

Spring damping in Energy Function
Supposing a behavior function $C(x_1, \ldots, x_n)$, then we have a scalar potential energy function
$E = \frac{k_s}{2}C\cdot C$ where $k_S$ is stiffness constant.
Hence, the force is as follows $...

Fading particles and transition
I'm trying to render a particle simulation. I want each particle to leave a trace. To achieve this I'm using a framebuffer and two textures. On each frame the algorithm goes like this:
Render to a ...

Cloud rendering and transparency order
I am working on a graphics engine designed to be used in flight simulators.
It therefore has to feature an advanced weather rendering system with clouds you can fly through.
For this, I implemented a ...

Are there tricks for getting proper sort ordering on particle systems?
If you have a bunch of particles to render, using different shaders and/or render states, that have some level of transparency, the naive solution of sorting all particles by depth can be extremely ...

Possible methods to deal with artifacts when drawing billboards to a cubemap
When drawing billboards to a cubemap, the billboard texture was incorrectly aligned on the boundaries of the cubemap between different sides.
My guess is that the false projection of the billboard ...

Pixel dispersion (dissolving) algorithms
This YouTube video of a flip-dot display (physical b/w pixels) shows the reverse of an effect that might be called dissolve or dispersion, i.e. a text emerges from noise by pixels moving in to form ...

Please help me understand what happens as an image is faded to black in order to time-step particle fading
I have a game that has simple particles (basically dots) moving around the screen leaving a trail.
My ultimate goal is to be able to change the opacity of the solid black fading texture each drawing ...
