GOTTA remember that!

And additional smoothing was SOLVED by @syntheticmagus - with a LOW-PASS-FILTER

How awesome. :pray: Boundless gratitude for any insight to anyone.

Maybe … perfect curves exist afterall???

We will see. :grin:

STATUS: attempting to use the PATH~EDITOR for character path BOUNCE animation… so WE can crash into the planet… of course! And so, really need 10-key-camera…
image
…to view all these tiny points - from every angle - EASILY. TenKeyCam (next)

Looks more like an irregular-heartbeat, for now, but…

GREAT for drawing PATHS in 3DSpace - now new and improved - designed to extend!!!

Including:

  • stretch, point-density, rotation, scale, curves, “anmz” and “camz”: [lookAt, LookUp, ZoomIn, etc].

YES - highly desire EDIT SPLINE in 3D!!!

But I am ONLY a bird.

Introducing: TEN-KEY-CONTROLLER

  • have a look. A powerful concept to use 10key in 3D, in multiple MODES. :slight_smile:
    /***********************************- TEN-KEY-CTRL -***********************************\
    - use 10 Key ui to give yourself super powers in BABYLON!!! 
    - use the 5 key to toggle between MODES
    - the MODES (below) are: 'cam','edit','anm', also 'game'  
    - extensible in many ways.
    - example: Alt key changes magnitude of movement, OR direction of rotations, etc-.
    \**************************************************************************************/
    nx.tenKey={mode:'cam'};

            var direction = (nx.ui.ctrl.fwd || nx.ui.ctrl.rgt || nx.ui.ctrl.up || nx.ui.ctrl.lookdwn) ? 1 : (nx.ui.ctrl.lft || nx.ui.ctrl.bwd || nx.ui.ctrl.dwn || nx.ui.ctrl.lookup) ? -1 : 0;

                runSequence("CrashSequence")
            }
        }
    }

Trigger tenKeyCtrl like this:


                //------------------------------------10-KEY-CONTROLS-.
                case 101: //numpad 5KEY - MODEKEY
                    nx.tenKey.nextmode=1; nx.tenKeyCtrl();
                    break;
                //------------------------------------10-KEY-EDITING-.
                case 104://numpad 8FWD
                    nx.ui.ctrl.fwd=1; nx.tenKeyCtrl(); 
                    break;
                case 102://numpad 6RIGHT
                    nx.ui.ctrl.rgt=1; nx.tenKeyCtrl();
                    break;
                case 98://numpad 2BACK
                    nx.ui.ctrl.bwd=1; nx.tenKeyCtrl();
                    break;
                case 100://numpad 4LEFT
                    nx.ui.ctrl.lft=1; nx.tenKeyCtrl();
                    break;
                case 103://numpad 7UP
                    nx.ui.ctrl.up=1; nx.tenKeyCtrl();
                    break;
                case 105://numpad2 9DOWN
                    nx.ui.ctrl.dwn=1; nx.tenKeyCtrl();
                    break;
                case 97://numpad1 
                    // runSequence("CrashSequence")
                    nx.ui.ctrl.lookup=1; nx.tenKeyCtrl();
                    break;
                case 99://numpad3 
                    nx.ui.ctrl.lookdwn=1; nx.tenKeyCtrl();
                    break;
            }    

            if(e.altKey) { nx.ui.ctrl.alt = 1 }
            else { nx.ui.ctrl.alt =  0}

If someone asks, I try PG. :eagle:

Moving on… :heavy_check_mark:

  • With TenKeyCAM, can finish the bounce animation, switching between: anm, cam, and edit - without ever leaving the keyboard!!!

  • The TenKeyCam was needed to precisely make EDITS from many angles: freecam with rotation.

NOTE: publishing the PATH is done with the P key and the code is a STRINGIFY!!!:

    var printRecordedPath = function(){
        console.log('PUBLISH:'); //PUBLISH-RECORD-.
        console.log(JSON.stringify(nx.bouncePath)); //PUBLISH-RECORD-.  
}

Then the EDITED PATH array can be copied from devtools and saved into the member variables…

Someday, someone will find this thread. Who is like me. That is who it is for…


#44

@nasimiasl - I see your YouTube videos on Geometry Builder. Excellent!

GOAL: How to make SandDunes???

Import CURVE from Inkscape… EPIC!

Then Extrude? Smooth. Material…

Last, Export Geometry?

I’d like to learn. Will try soon…

Thank you,


#45

i work on video with sub title that explain all
that video is GB core
i have GB ver 1 and 2
i start some project after i finish step 1 (in 6 months) i have a perfect tools for Geometry Builder
i dont know we can make it Open but i wanna have free plan for BABYLONJS forum’s members

*** we have GB core in BABYLON.Extensions for now

I wish I understood you more falcon… haha I really feel like you are working on some good stuff sometimes but have trouble deciphering what is going on.

I think as more people get a better idea of what you are doing as you pull it together more an they get a better idea of whats going on there will be more discussion for you to get into.


#48

Rock and Roll, Rock and Roll!!! :musical_score:

@nasimiasl and @Pryme8 … you guys are great, your talent is very impressive.

HOLY COW :cow2: everyone -> NAS just CRUSHED SandDunes!!!


I knew you could do it! But, even my gamer son is impressed… highest honor. :trophy:

How in the world??? I will try core Extension for GB… today!

Super cool you use INKSCAPE for CURVES. Like. :+1:

…WOW… “Perfect Curves!”

I will try to LEARN and let other people know.


Pryme8, thanks for wise words and encouragements.

I believe BABYLONs best days are AHEAD. :slight_smile:


#49

NOTES for NAS:

geo, PushVertex, MakeFace…

3 doubly-nested for loops?

Scaling Vertices and uvs.

Why twice?

3?


3! MakeFace - i get it.

segments…

pow()???


Dropping into GeometryBase()…

builder() callback function, RECURSIVE through extension! :black_heart: Oh!


Look at that Shader!

What is it doing?

ShaderBuilder. Map . InLine… Sand texture, nice.

  • look at those Dot Products!

.BuildMaterial.

Mesh.material

Then - again with collisions??? Oh, that is interesting!


This 1 shader … is all the beauty:

            .InLine(`float h = 1.-min(1.,max(0.,pow((pos.y-10.)/30.,1.)));
            float fs = dot(nrm,normalize(pos-camera));
             float fs2 = dot(nrm,normalize(pos-vec3(1000.)));
            result.xyz  = min(1.,max(0.,(1.2+fs*0.1+fs2*1.2) )) *result.xyz;
            `)

Is this the SHADOWS? Oh… it is making sense.

  • float, pow, dot, min.

Another Shader…

Reflections on SAND?

  • refract(), atan, SBP

How to wire it up i wonder…

Looks like it needs a scale, so on each vertex, face… uv. :slight_smile:


:baby_chick: …baby chick gets it.



Sand_Dune_HEIGHT:

3! Logarithmic SIMPLEX NOISE algorithms. Nice.

ToRef! I get that now… finally. :sunny:


FOUND THE NUM (in the NOISE) that builds SANDCASTLES:

Surf Around - it is so nice!!!

Sand Mountain

Happy - to be HALF AS GOOD AS NAS… someday. :slight_smile:

(Above) Amazing work by - @nasimiasl

~Impressive levels of Technical Talent and Mathematical Artistry in this community. :eagle:


#52

Ha, :wink: not all of my story is public.


#53

Mr. Mysterious!


#54

I think it is the “farm animals” thing. :smiley: You don’t want to “pry”.

A picture is only worth a thousand words. A BJS scene… maybe 10,000 words.

Some of my-my-my stories… are 10 million words long!

I would need “cargo art”. :slight_smile:


#56

My attempt at a halfpipe https://www.babylonjs-playground.com/#SQFG0Q#4

This uses function I have been working on over the past couple of weeks or so. More PGs here The Wingnut Chronicles

Will write up some docs over the next few days (or weeks)


#57

AWESOME JohnK!

Looking…

Nice, you didn’t need extrude!


- phi, theta, matrix, rotation.

Cool it TILTS!

  • lean, swivel, subtractToRef, atan2, and *=sign()??

#58

Thank you JohnK for leaving the comments in createSection

Found the ribbon… it is really interesting.


#59
void 0;

The fancy brother of “undefined”? Ok. :slight_smile:

I like it…


#60

Epsilon - limit
Theta - angle
Phi - golden ratio
NURB - non uniform rational basis spline


#61

you have a lot energy aFalcon :wink:


#62

Everyone says falcon is intense.

A person can accelerate or suppress…


Really enjoyed Geometry Builder…

… and that awesome “builder” (recursive callback) PATTERN.
