More WIP on R3PU

[Michael Lobko-Lobanovsky]

DL'ed OK.

Looks great for starters... There can be several concentric rings of bubbles of different sizes and speeds in the same tube to emulate random bubble flow...

[UPD] The other, left-side half of torus can be made fully opaque to hide the bubbles flowing wrongly downwards...

[Michael Lobko-Lobanovsky]

Patrice,

I need two more separate torus meshes concentric with the existing torus: one of slightly smaller torus tube diameter, and the other one, of slightly larger one, so that the smaller one would fit tightly inside the tube of the existing torus and together they would fit tightly inside the tube of the larger one. The both toruses should be nicely normilized and equipped with tex coords like the existing one.

I also need a transparent texture that should emulate veritably an air bubble to be used instead of the pearl-like glistening gem balls currently rotating in the torus. (can there be a circle of 2D billboards instead of balls if it is impossible to emulate a 3D ball air bubble with a texture?)

Can you do that for me, please?

(I'm going out for the whole day tomorrow on Thursday but I'll be back home on Friday and I could use the above assets then, if of course you agree to help me out with them)

Patrice,

FYI: the innerpart_ks.png texture you're using in your mat files doesn't exist because you forgot to rename its current sibling innerpart_roughness.png accordingly.

Traditionally in the industry, positronic robotic brains have always been drawn in neon-glowing cyan. What would you say aesthetically to this version:

[Patrice Terrier]

For the 2d billboard texture maybe we can use the one of my buble plugin, that is also the same used in my charting demo.
For the concentric torus tube a quick draw would help me to better figure what to do.
About the Ghost rider color it was just the one from my first brain projject without animation but of course  we can use anther color like yours with the animated version.
Note, i am typing this message  from  my android phone., not as easy than with a regular keyboard 😯

Patrice,

My English seems to be letting me down.

[Patrice Terrier]

Ok, i better figure it now, and i shall do it quickly.
(a good draw is better than a thousand words )

I have attached the Bubble texture i am using with my BB plugin.

And of course

can there be a circle of 2D billboards instead of balls if it is impossible to emulate a 3D ball air bubble with a texture?

How would you rotate the 2D billboards into OR?

[Michael Lobko-Lobanovsky]

Example of animation with fluid and bubble.

  A-a-a-a-a-a-a-a!!! Excellentissimo!!!

Are those billboards or 3D balls?

Can you send me this setup as a separate "brain unit" model to spare the 45 seconds of loading the entire robocop? I would love to play with it myself...

Can I also have the two toruses, please? I'll split the outer one vertically in two and use its left half as an opaque cover for the transparent torus tube. I'd like to see how it would look with the downwards flow hidden from view...

(Was it your real voice in the video? )

[Patrice Terrier]

Here is the bb.obj to ease your test.

The voice you hear in the video, is the internet radio i was listening

Note: Even trying hard for a couple of hours, i was unable to use billboard with it

[Patrice Terrier]

Here is another solution if you only want to see the up fluid flow.

BTW: Looks like, we can't use "Save to image" while an animation is playing...

[Michael Lobko-Lobanovsky]

Here is another solution if you only want to see the up fluid flow.

It isn't "another solution", it is "another part of solution" because I'd actually like to see several tubes "feeding" the brain. Probably of different diameters and colors and bubbles.

[Patrice Terrier]

I made a few changes to the materials of my personnal version, see if you can say what has been changed 

[Michael Lobko-Lobanovsky]

-- Different custom wallpaper
-- Brain color reverted to infrared
-- Torus tube has seemingly opaque casing (outer torus or yet one extra outer torus?) -- full on the left, partial on the right. At least descending bubbles are not seen through it any more while brain is... ()
-- Formerly steel innerpart turned semi-transparent ()

[Patrice Terrier]

- The color of the "mask_gen" mesh has been reworked to better match the original.
- The helmet border mesh has been made thiner, because it was going inside of the "bone_skull"
- I have added a new opaque "tor_tube" mesh.

I have been playing with a few more bubbles, see the attachments.

[Patrice Terrier]

Small changes to apply to the source code to use "Save" and "Print" while in animation mode.

In ProcessMenu
    case MENU_WALLPAPER:
        if ((long) SendMessage(GetDlgItem(hWnd, IDC_ANIMATION), BM_GETCHECK, 0, 0) == BST_CHECKED) { gP.nRotation = 0; } // PAT 08-04-2018
        gP.capture = USE_FILE; // 05-22-2015
        gP.redraw = -1; // Redraw the OpenGL scene
        break;

    case MENU_PRINT: // 05-22-2015
        if ((long) SendMessage(GetDlgItem(hWnd, IDC_ANIMATION), BM_GETCHECK, 0, 0) == BST_CHECKED) { gP.nRotation = 0; } // PAT 08-04-2018
        gP.capture = USE_PRINTER;
        gP.redraw = -1; // Redraw the OpenGL scene
        break;

In gl_DrawScene
    if (gP.capture) {
        if (gP.capture == USE_PRINTER) {
            gP.capture = 0;
            SendToPrinter();
        } else {
            gP.capture = 0;
            SaveToImage();
        }
        if ((long) SendMessage(GetDlgItem(gP.hMain, IDC_ANIMATION), BM_GETCHECK, 0, 0) == BST_CHECKED) { gP.nRotation = -1; } // PAT 08-04-2018
    }
