I'm at a.maze in berlin with my friends from @symmetrybreak.bsky.social. Anyone there too?

But... I'm 30 and I love C?

From the Unity3D community on Reddit: My story of developing a grass shader Explore this post and more from the Unity3D community

Hey y'all,
www.reddit.com/r/Unity3D/co...
did a write-up about Tasty Grass Shader over on Reddit :)

A column of fire envelops an RV in a pine forest late at night.

My bedroom and office reduced to ashes. The metal walls and roof are largely destroyed, revealing the forest beyond.

A class C RV gutted by fire. The heat of the fire has killed most of the plant life in a nearby garden.

A segment of an RV's exterior wall. The heat of the fire has melted through the aluminum panels.

An E-bike battery burned my house down on the first day of GDC. Seeking mutual aid from financially stable colleagues.

And on top:

Just because you got Volumetric Light, it doesn't mean that everything is shrouded by fog.

The Half-Life 2 RTX looks fantastic, but could people PLEASE respect the original art direction?

Just because you have path tracing doesn't mean you crank all your lights by x10.

Just because you got PBR now doesn't mean all your surface should have 0.0 roughness.

look at what we've been up to!

endlich wieder twitter vibes hier

#include <xmmintrin.h> void Distances_SIMD(void) { float points_X_arr[] = {16.0f, 00.0f, 10.0f, 43.0f}; float points_Y_arr[] = {00.0f, 16.0f, 10.0f, 08.0f}; __m128 points_X = _mm_load_ps(points_X_arr); __m128 points_Y = _mm_load_ps(points_Y_arr); __m128 xSqr = _mm_mul_ps(points_X, points_X); __m128 ySqr = _mm_mul_ps(points_Y, points_Y); __m128 length = _mm_sqrt_ps(_mm_add_ps(xSqr, ySqr)); float lengths[4]; _mm_store_ps(lengths, length); for(int i = 0; i < 4; i++){ printf("Point = (%f,%f), Length = %f.\n", points_X_arr[i], points_Y_arr[i], length[i]); } }

This concept is of course possible with Vector2/3/x as well. Take this example, where I calculate the magnitude/length of four 2D points at once.

Keep in mind: I barely scratched the surface here of what's possible, not to mention that SEE1 came out in 1999.

Happy Coding!

(5/5)

Now for thinking as SIMD as "multiple things at once" the code would look like this.

The key is here that we batched multiple calculation together, processing 4 circles at once.

(4/5)

void CircleArea_SIMD(void) { float circlesRadii[] = {1.0f, 2.0f, 0.5f, 4.0f}; __m128 circlesRadius = _mm_load_ps(circlesRadii); const float pi = 3.141f; __m128 pi_wide = _mm_load_ps1(&pi); // caluclate: pi * radius * radius, but for 4 radii at once. __m128 areas = _mm_mul_ps(pi_wide, _mm_mul_ps(circlesRadius, circlesRadius)); float areaScalar[4]; _mm_store_ps(areaScalar, areas); for(int i = 0; i < 4; i++){ printf("Radius = %f, Area = %f.\n", circlesRadii[i], areaScalar[i]); } }

Instead, you have to think about SIMD as processing multiple items at a once. For example: you have a list of circles and want to calculate their area. The basic version would process one circle at the time.

With thinking of SIMD as "fast Vector4" there would be no room for improvement. (3/5)

The key point is that many people get the *impression* that these wide SIMD vectors, like __m128 in SSE, are a direct replacement for a Vector4. When they then try to "SIMDfy" their Vector3/2 math, their code gets ugly and inefficient.

This is not how to SIMD.☝️ (2/5)

I always wanted to get into SIMD programming (SSE, AVX, NEON all that sorts), but never found the right entry, until I stumbled across this talk deplinenoise.wordpress.com/wp-content/u... (1/5)

Just the "front-end". The geometry is generated via compute shader, which doesn't depend on any render pipeline. The shader graph just handles geometry unpacking and material setup.

(Also, no render passes involved, just OnBeginCameraRendering and Graphics.DrawProcedual())
