Alps - shader of the week contains 2 typos in line #262.
I wonder why such bugs slip through in Shadertoy but not in GLSL Hacker?

replace Map(p) < .5 ? dist.x = halfwayT : dist.y = halfwayT;
with     Map(p) < .5 ; dist.x = halfwayT ; dist.y = halfwayT;

3D-Tech News Around The Web / TWGL: A Tiny WebGL helper Library
« on: July 05, 2015, 05:21:00 PM »
TWGL's is an attempt to make WebGL simpler by providing a few tiny helper functions that make it much less verbose and remove the tedium.
TWGL is NOT trying to help with the complexity of managing shaders and writing GLSL. Nor is it a 3D library like three.js. It's just trying to make WebGL less verbose.

AMFS: Adaptive Multi-Frequency Shading for Future Graphics Processors

The researchers [...] propose a powerful hardware architecture for pixel shading, which enables flexible control of shading rates and automatic shading reuse between triangles in tessellated primitives.
The main goal is efficient pixel shading for moderately to finely tessellated geometry, which is not handled well by current GPUs.

Galactic Civilizations* 3 (GC3) is a turn-based 4X strategy game developed and published by Stardock Entertainment that released on May 14th, 2015. During the early access and beta periods, we profiled and analyzed the rendering performance of the game. One of the big performance improvements made was the removal of several CPU-GPU sync stalls that were responsible for losing some parallelism between the CPU and GPU. This article describes the issue and the fix and emphasizes the importance of using performance analysis tools during development, while keeping their strengths and limitations in mind.

...

Optimizing the rendering performance of a game is a complex beast. Frame and Trace capture-replay tools provide different and important views into a game’s performance.
This article focused on CPU-GPU synchronization stalls that required a trace tool like GPA Platform Analyzer or GPUView to locate.

3D-Tech News Around The Web / NVIDIA HairWorks 1.1 Release

NVIDIA HairWorks makes it easy to bring hair and fur to life—in real-time. It builds on the prior release, which focused on fur authoring, rendering, and simulation. With HairWorks version 1.1, NVIDIA has added support for authoring, rendering, and simulation of long-hair assets. The release contains a variety of sample assets that let artists create completely different types of hairstyles.

Check out also 500k hair video

The samples can be controlled with these buttons
(B)ones
(G)eometry
(H)air
(P)ause

AMD recommends to lower tessellation level
to gain performance.
Even without that fix rendering looks "a little bit" worse.

General Discussion / Re: Frequent TDRs with GTX 760
« on: July 05, 2015, 09:22:13 AM »
Looks like a wide-spreaded issue. The official GeForce forum is full of complaints.

Try NVIDIA GeForce Hotfix driver 353.38 or roll back to older drivers; R350.12 / R348.17 aint affected.

ShaderParticleEngine

A GLSL-focused particle engine for THREE.js. Removes a lot of the heavy lifting away from the CPU and onto the GPU to save precious rendering time in busy scenes.
Pull requests and issue reports welcome. Please see the notes on pull requests at the end of this document.

I was a bit puzzled how the micro shaders at Shadertoy work, but i think i found a good formula now:

Replace Shadertoy's pixel shader code  void mainImage( out vec4 f, vec2 w ) with:

Code: [Select]
#define f gl_FragColor
// modify values until it fits
#define objectsize 500
#define leftright 0
vec2 w = gl_FragCoord.xy / iResolution.xy * objectsize + leftright;
void main()

3D-Tech News Around The Web / (WebGL) ioquake3.js

ioq3.js is a port of ioquake3 to the web using Emscripten. It was heavily inspired by inolen's quakejs, but aims to be simpler and up-to-date with the latest Emscripten features. It also aims to implement high-speed multiplayer matches via WebRTC.

Note: The Quake 3 engine is open source. The Quake III: Arena game itself is not free. You must purchase the game to use the data and play Quake 3 with ioquake3, or play another game made with this engine. This WebGL demo uses the official shareware demo assets.

Default arena works; full version not tested, i would have to search my Dreamcast version in the attic  :-*

About Flight Arcade

Flight Simulator has been on the cutting edge of computing for over three decades. Learn about bringing it to the modern web.
 Graphics The first version of Flight Simulator shipped in 1980 for the Apple II and, amazingly, it was in 3D! That was a remarkable achievement. It’s even more amazing when you consider that all of the 3D was done by hand, the result of meticulous calculations and low-level pixel commands. When Bruce Atwick tackled the early versions of Flight Simulator, not only were there no 3D frameworks, but there were no frameworks at all! Those versions of the game were mostly written in assembly, just a single step away from ones and zeroes that flow through a CPU.
When we set out to reimagine Flight Simulator for the web, we couldn’t help but think about the contrast of creating 3D then and now. Modern coding seems almost luxurious as we sculpt 3D worlds in WebGL with great frameworks like Babylon.js. It lets us focus on very high level problems. In this article, we’ll share our approach to one of these fun challenges: a simple way to create realistic looking large scale terrain

Steering is hard coded for keyboards, someone should tell Microsoft about the existence of touch screens.

Is possible that ms opengl32.dll check and load external opengl? I mean in windows who checks for opengl?
...
NOTE. overwriting opengl32.dll with my driver igdogl32.dll GPU_Caps_Viewer_1.23.0.2 report: impossible find enter point glTexImage1D in library GLU32.dll

Here is the reference in registry for NVIDIA, should look similar for Intel
Code: [Select]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{magic number}\0000]
"OpenGLDriverName"=hex(7):6e,00,76,00,6f,00,67,00,6c,00,76,00,36,00,34,00,00,\
  00,00,00

The entry points can be double-checked with GLinspector 0.1.0 (link broken atm)
