idea of demo based on rosler attractor

Six main rays:


Four rays:

Hi Alfonso,

A small example to calculate a 6 point star image.

Code Select Expand

const    float4 constant_pool:register(c0); // constants received from CPU
#define  iResolution constant_pool.xyz  // viewport resolution in pixels (width, heigth, aspect ratio)

static   float star_size = 1.0/3.0;

float4 ps_main(float2 fragCoord:vpos):color // ps_3_0 input semantics, vpos contains the current pixel (x,y) location. This is only valid with ps_3_0.
{
    float3 color = 0.0;
    fragCoord = abs(fragCoord + fragCoord - (color.rg = iResolution.xy)) / color.g;
    color += 1.0 - 2.0*pow(( pow(2.0*fragCoord.x, star_size) + pow(fragCoord.x + fragCoord.y*1.7, star_size) + pow(abs(fragCoord.x - fragCoord.y*1.7), star_size))*0.333333, 1.0/star_size) - color;
    return float4(color,1.0);
}

Stars with coloring techniques.

That's great Marinus, thank you :t

A new sprite for an old demo as a starting point
Don't forget the tune

Edited: bigger sprite and window. Can be viewed in full screen.

this is stars I want to make starfield with

Hi!!

Just beginning to play with some color changes in "orbiters". Now some minimum effect with velocity (and until 500000 points in global memory)

looks good  :t

Thanks daydreamer!

Here is some quite amazing pattern resulting from the product of x, y and z changes. Green is 0.25-1.75 times product media, red less and blue more.

looks good,thanks now I got ideas,make whole thing bigger and use christmasballs sprites instead?

We will see what you can do  :t

ddraw christmasball test(no attractor yet),downsized from 1920x1080 to 1024x768
not finished yet need highlight etc,realtime christmasball1 fpu,realtime christmasball2,scalar SSE
not applied clipping yet so it behaves like pixelshader code for all pixels

Packed SIMD christmasballs

I cant say this on the forum
BUT i luv this sh.......
Thanks guys this is why I adore asm

wouldnt it be a good idea to make this SIMD multithreaded Raistlin?I dont know how many cores each of us have except I have 4 cores on the new one,so maybe max two threads to begin with?
computing power->beautiful attractors
