News: About the NVIDIA DLSS 2.0

This past week, NVIDIA announced an update to its Deep Learning Super Sampling technology, aptly dubbed DLSS 2.0.
Deep Learning Super Sampling named DLSS is an NVIDIA RTX technology that uses the power of AI to boost your frame rates.
DLSS essentially takes lower-resolution imagery, and intelligently upscales it to looks like native, higher-resolution output.
Performance was universally improved to varying degrees since the game was being internally rendered at a lower resolution, but image quality wasn’t always optimal and sometimes resulted in unwanted artifacts.
The old DLSS 1.0’s effect on game visuals and performance was a mixed bag, that varied from title to title.
The new DLSS 2.0 comes with DLSS 2.0 improved the quality, balanced, and performance by leveraging the Tensor cores available in its GeForce RTX-series GPUs.
Let's see one example:

Unity 3D : About VFX Graph.

The official webpage of the VFX Graph for Unity 3D comes with a short intro.
The install steps can be seen on this webpage.
I started today to follow one video tutorial about fire and smoke from youtube channel named Brackeys.
This video tutorial can be seen here:

Some conclusions about my test with an old video card:
  • you need a good video graphic card;
  • you need a unity version with Package Manager;
  • I found some new changes using with the Unity 3D version 2019.3.5f1;
  • many changes in the 
  • the one is the Output Particle Quad with many changes into variables;
  • I cannot set the TotalTime, this crash it all;
The result is this:

The settings for this smoke effect using the Visual Effect Graph Asset can be seen in the next image:

Unity 3D : Use Quick Fix on Visual Code for Unity and Linux.

Because I don't use Unity 3D with Linux and Visual Studio today I solve another issue for the development area.
This is the quick fix option for Visual Code that helps the user to add source code.
For example, you can add source code for the implement an abstract class PlayerBaseState:
using UnityEngine;

public abstract class PlayerBaseState 
{
    public abstract void EnterState(PlayerController_FSM player);
    public abstract void Update(PlayerController_FSM player);
    public abstract void OnCollisionEnter(PlayerController_FSM player);
}
Create a new C# script named PlayerIdleState. The script needs to be changed into this source code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerIdleState : PlayerBaseState
{
    
}
Select the PlayerIdleState and use these keys: Cmd or Ctrl and . (the point key) .
This will show a menu named Generate overrides... and help the developer to generate the new code:
The result is this source code with all new override for each of methods of PlayerBaseState class:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerIdleState : PlayerBaseState
{
    public override void EnterState(PlayerController_FSM player)
    {
        throw new System.NotImplementedException();
    }

    public override bool Equals(object obj)
    {
        return base.Equals(obj);
    }

    public override int GetHashCode()
    {
        return base.GetHashCode();
    }

    public override void OnCollisionEnter(PlayerController_FSM player)
    {
        throw new System.NotImplementedException();
    }

    public override string ToString()
    {
        return base.ToString();
    }

    public override void Update(PlayerController_FSM player)
    {
        throw new System.NotImplementedException();
    }
}

Unity 3D : Settings for Android build game.

If you try to set the Android SDK on Unity 3D using the Linux O.S. then you can have a problem.
After you set the name of the package and the default android settings you can use External Tool from menu Edit - Preferences to set paths for Android SDK, NDK, and more.
This is the path I used to build with Android:
  • /home/catalin/Unity/Hub/Editor/2019.3.5f1/Editor/Data/PlaybackEngines/AndroidPlayer/OpenJDK
  •  /home/catalin/Unity/Hub/Editor/2019.3.5f1/Editor/Data/PlaybackEngines/AndroidPlayer/SDK
  • /home/catalin/Unity/Hub/Editor/2019.3.5f1/Editor/Data/PlaybackEngines/AndroidPlayer/NDK
  • /home/catalin/Unity/Hub/Editor/2019.3.5f1/Editor/Data/PlaybackEngines/AndroidPlayer/Tools/gradle
You can see the android SDK, NDK and Gradle is set on the Hub Editor This is my External Tools configuration for that build game:

Unity 3D : The new learning area ...

Shadertoy: The flag of Romania - 002.

This is another step about learning shaders.
The old example can be updated with this source code.
I commented on the source code to see step by step how this working.
One way to understand how this working to the final result is to going back on the shader structures that generate output to the basic elements of the shader.
If we apply this case to solve the problem then from the display a color like a vec4 color for fragColor adding a sin function to wave the result, and so on.
Right, this code can be optimized in many ways depending on the result.
// learning process area step by step 
// the gl_FragColor is a vec4 type of float values in the range 0 to 1.
// because the values are from 0 to 1  this can used in many ways with for domain and range
void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
    // Normalized pixel coordinates (from 0 to 1)
    vec2 uv = fragCoord/iResolution.xy;
    // define a vec2 and uv can be divide to create waves 
    // use this to see the difference 
    // vec2 valul = vec2(0.01,1.0);
    vec2 valul = vec2(0.5,1.0);
    // define a vec2 this vector will be the vector of shadow
    vec2 unghi_valul = vec2(0.5,1.0);
    // this float will speed the animation with iTime
    float viteza = 3.0;
    // with the dot we can calculate the dot product of two vectors and result can be a shadow
    // the result of unghi can be changed when change the vectors and vectors math rules
    float unghi = dot(uv/valul, unghi_valul) - iTime * viteza;
    // the output can be used with sin to create a shadow wave
    // fill the screen with red
    fragColor = vec4(1,0,0,0) * sin(unghi);
    // fill the 2/3 of size with yellow color
    if(uv.x<(1.0/1.5))
    fragColor = vec4(1,1,0,0)  * sin(unghi);
    // fill the last 1/3 with the blue color 
    if(uv.x<1.0/3.0)
    fragColor = vec4(0,0,1,0)  * sin(unghi);
}

Shadertoy: The flag of Romania - 001.

Today I make the flag of Romania.
About this flag you can read at Wikipedia.
The goal of this simple tutorial is to learn the link between iResolution and the fill areas.
First, you need to normalized pixel coordinates from 0 to 1.
The gl_FragColor is a vec4 type of float values in the range 0 to 1.
We can use this property by fill the areas of the screen.
The example can be changed to use the RGBA.
The source code is this:
void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
    // Normalized pixel coordinates (from 0 to 1)
    vec2 uv = fragCoord/iResolution.xy;
    // Output to screen
    // fill the screen with red
    fragColor = vec4(1,0,0,0);
    // fill the 2/3 of size with yellow color
    if(uv.x<(1.0/1.5))
    fragColor = vec4(1,1,0,0);
    // fill the last 1/3 with the blue color 
    if(uv.x<1 .0="" code="" fragcolor="vec4(0,0,1,0);">
This is the result of this shader:

The neon effect with javascript P5 JavaScript library.

The P5.js is a JavaScript library for creative coding.
You can use by adding this link on your HTML area using the script tag:
https://cdnjs.cloudflare.com/ajax/libs/p5.js/0.9.0/p5.min.js
You can use it like any JavaScript library.
You have two functions: setup and a draw for setup and drawing.
function setup() {
  createCanvas(window.innerWidth, window.innerHeight);
}

function draw() {
  ellipse(50, 50, 80, 80);
}
Then you can fill these functions with any javascript code.
You can see a neon effect with two bezier functions.
The example uses the mouse movement to change the bezier lines.
You can see many examples created by me at codepen website.

NVIDIA video cards and CUDA feature.

Today I search on web information about video cards for processing, neural networks, and rendering.
If you use it with Blender 3D software or Neural networks then you need a GPU with CUDA feature.
My destop works with an old NVIDIA Corporation GT218 [GeForce 210] (rev a2) video card and this not help me very much.
The CUDA platform is a software layer that gives direct access to the GPU's virtual instruction set and parallel computational elements, for the execution of compute kernels. see Wikipedia.
This software uses the CUDA feature. Let's see all of these informations about desktop Nvidia GPUS ordered by CUDA core count.

Cinema 4D and Sketchfab.

Great news for Cinema 4D users.
Cinema 4D users can now access over 200,000 freely downloadable 3D models from Sketchfab using our new Cinema 4D Importer plugin. The plugin uses our Download API to let you search Creative Commons licensed models from our community and download them directly into your Cinema 4D scene. Models can be searched by keyword(s) or browsed. The addon then presents thumbnails of results and each one can be opened on Sketchfab.com for a full 3D preview if desired before downloading directly into Cinema 4D.
You can read more here.
