Title: [Axiom] AxeJH3D, a(n almost) complete axiom for 3D development !
Post by: Matrefeytontias on March 02, 2013, 03:44:39 pm
Hi guys !

Some of you may be aware of my "super-secret-project", and now that it reached a releasable state, I don't make you wait any more :P

So, the project I'm working on is an axiom (ASM for Axe so) which allows you to work with 3D vertices in a high-level way. Before saying anything, please know that I didn't made any 3D calculus during the development of this axiom. I just ported the 3D routine set Juha3D (http://tift.tuxfamily.org/projects/juha3d) by yhean from pure ASM to Axe-friendly ASM, which still was a PITA that took me 27 days, especially because I've fully done it with Mimas (yeah, I'm a great Mimas fan) ;D So, all credits goes to him (wherever he is now) for the 3D calculations (and I would especially thank him for his wonderful macros and SMC that aren't allowed in an axiom coded with Mimas and which gave me strong headaches).

Instead of explaining the way it works any further, have a look at the 3 current commands of the axiom, which are all available in the [PRB] menu ([math][?]) :

 Command Token Effect CalcMatrx(x_angle,y_angle,z_angle) randInt( Calculates the rotation matrix given the X, Y and Z angles. The matrix is written to the whole 9 bytes of OP1, this means that it got destroyed by float{}, GetCalc or a call to Ans (tell me if I forgot something). RotVertx(x_coord,y_coord,z_coord,outputArea) randNorm( Rotate a vertex given its X, Y and Z coordinates according to the rotation matrix calculated with a previous call to CalcMatrx and writes the resulting coordinates to the 6 bytes starting at outputArea. ProjVertex(x_coord,y_coord,z_coord) randBin( Converts 3D coordinates into 2D ones. Basically, it takes a point in space and converts it into a point on screen. It returns the X coordinate in L and the Y coordinate in H, so make a modulus 256 on the returned value to have the X coordinate, and divide it by 256 to have the Y coordinate. Don't forget that you'll need to use a camera offset (distance from the camera to the plan) to avoid having the vertices display right on your face !

And now ... examples time :D !

The classic cube :
(http://mattias.refeyton.fr/espace-ti/axeJuha3D/exampleCube.gif)
8 vertices, 12 links, 4 calls to getKey, 29 FPS

Omnimaga's logo :D :
(http://mattias.refeyton.fr/espace-ti/axeJuha3D/exampleOmniLogo.gif)
20 vertices, 30 links, 4 calls to getKey, and still strong - 14 FPS !

Trip through the galaxy !
(http://mattias.refeyton.fr/espace-ti/axeJuha3D/exampleStarfield.gif)
32 vertices, no links, 4 calls to getKey, moving camera, 12 FPS

I attached the axiom itself, AXMJH3D.8xv, and the source of the cube program as a small example, CUBE.8xp.

Note that it's not a complete project. Yeah, it's only a port of Juha3D, but I'm actually looking for people who would want to get into it with me in order to build a full axiom that could provide by himself all the functionalities that working with volumetric objects would require (scaled down to calc dev of course, so I'd be really happy only with polygon filling, but I'm sure people can think - and realize - better than only that ;) ).

So, to make it clear : if you want to team up with me to carry this axiom even further, do a big up ;)

Have fun, and share comments !

Ok that is really cool. i wonder what kinda 3d games we might get out of this now :D

Also one thing that i think would help a project like this is writing a custom screen drawing routine so you can shove some of the math/maintenance code in the lcd delay for a hopefully decent speed up where applicable

Thanks :D I first thought about a Star Fox like or something ...

EDIT to answer your EDIT ;D : the axiom itself only does calculations and doesn't draw anything, I'm just using Axe's routines to display something.

What im saying is. If you were to offer a function to handle screen updates you could put some of the work in the delay and there for save some clock cycles. Its just an idea.

There is already a StarFox project by thepenguin77, but it only runs for 15MHz models, so not for your 83+.

Will the Axiom support solid walls (even if they are only white, with no textures) or only wires ?

Wow looks very nice. THe first two screenshots look quite fast and the 3rd one reminds me of Final Fantasy ending splash screens. :)

Also I didn't know Juha3D was actually released. Back in 2003 the official site was just a giant ASCII art with no more download link.

That Starfox project used plenty of cheating techniques to simulate 3D and get around limitations, though, so it might not be 100% 3D (although I think if you modify the source it's perfectly useable for games and levels)

This project is by long discontinued. Also yeah, I forgot to mention that the programs on the screenshot all runs at 6 MHz ;)

And yeah, solid surfaces are my next item on my list. That's why I mentionned polygon filling.

And thanks DJ_O :)

That's great to hear anyway :D

Matrefeytontias: This is amazing o.o It works so smoothly! I had just finally figured out 3D stuff yesterday, so I made a BASIC program, but this is gorgeous o.o I am now looking forward to the upcoming TI-Concours stuff in Axe/Assembly O.O If we do Snake or something, are you going to make it 3D? XD

Unfortunately, I don't think I'll participate to the contest, mostly because the family didn't like my grades during the first trimester. Dunno why ;D

But after the polygon filling is done, I think I'll start with a terrain generator, so you'll can walk on it :)

Yeah that's it, and thanks :)

Also, if you cant think of more things that you would like have added to the axiom, say it ;)

I think that with solid walls (or polygon filling as you say) would be enough but textures would be a great addition (but it will be harder to implement I guess).

Yeah, maybe we'll (with ben_g) do that, but first we have to get the solid surfaces working :)

methinks you should add some automagic stuffs, such as an automagic running the commands in sequence for display with specified input.

Edit: there is a small with the starting coordinate plane: the Z plane is parallel to your line of sight... It should be where Y currently is, X should be where Z currently is, and Y should be where X currently is

Will filled polygons be grayscale or will it be checkerboards like in tr1p1ea's engine??
Title: Re: [Axiom] AxeJH3D, a(n almost) complete axiom for 3D development !
Post by: Matrefeytontias on March 04, 2013, 03:30:50 pm
We'll try with greyscales (most likely 3), and if it's too ugly, we'll go with checkerboards.

@pimathbrainiac for me the 3D coordinates always were :
Code: [Select]
`^ Y|||         __--> Z|  __--|-------------------> X`

Yeah, that's what he meant. People usually do this:
Code: [Select]
`          ^ Z          |          |          |          |           |-------------------> Y     __X <--`But as long as the code works, that is not really a problem with good documentation :)

/me was confuzzled when he first programmed...

Just wanted to make things less confusing for those who learned it the way Hayleia said.

Bump!

2 things:

1: May I please have a look at the source for this? I want to see it.

2: When I use this code:

Code: [Select]
`.A#Axiom(AXJH3D)ProjVertex(1,1,5)->AWhile 1ClrDrawPxl-On(A^256,A/256)DispGraphEndIf (getKey(15))`
The program just exits when I run it. Will you please create a tutorial on the usage of the Axiom?

Edit: Wait a sec. This was due to my compile settings being bad. Disregard the second bit.

Post by: Matrefeytontias on April 21, 2013, 04:22:07 pm

Also, I think I'll let this project like it is. I overestimated myself, I realized that I had just enough knowledges to make an axiom out of already existing code. So I'll gladly let my place to whoever thinks (s)he can bring the axiom further. Maybe I'll work on it again, but later.

Sucks that this died :(. That said I think TheMachine02 needed help with his 3D lib in Axe, so I wonder if you could team up with him or something to help?

Also I think a 3D Axiom should have a non-rendered mode, for people who wants max speed but don't care about quality/seeing through polygons. Space Dementia was like that and it did the job pretty well as a game.

Well, likely not at any decent speed. Remember, with MC, you would need to implement worldgen(ok, maybe that's not TOO hard), mobs, fluid mechanics(albeit simplified), textures, combat mechanics, experience, and a bunch more.

Also, bear in mind that the minecraft-demo Chokosta was working on only had block placement, solid colored textures and save-load files, and that was already nearly at its limit :/

it's sure that a MC can't be done on a z80 even in 15MHz... it's require too much game mechanics, but I think that a VERY simplified engine can be done, though.
(like in black and white, no texture, only wired...)

No it's not ... It's too much camera work to handle. And you don't seem to see what long it takes to render an entire world each time you press a key.

Anyway, I had a genius flash some days ago, and I'm glad (and proud) to say that I'm back on this project (that was a short but useful pause :P).

Aaaaand I'm bringing a huge bunch of updates.

First, I wrote the Triangle( command, a real and efficient triangle filler. With ben_g, we started working on it three months ago (yes, three months), but we couldn't make it work properly, so a few days ago I got tired, and said that I gave up. BUT, the genius flash I talked about above permitted me to find the only (and silly ;D) error, so now it works !

(http://img.removedfromgame.com/imgs/doubleFilledRectangle.gif)

Also, since some people asked for some automagic (hello pimathbrainiac ;D), well, I wrote some :P

So, I added the Tri( function (not to mistake with the previously described command), which draws a 3D triangle out of three offsets and a vertices table, and the Quad( function, which draws a 3D rectangle out of four offsets and a vertices table.

I still need to work on the triangle filler, particularly to make it able to take a fourth parameter which will be the colour (0 → all black, 1 → white with borders, 2 → all white).

Anyway, using a little bit modified version of the axiom (I only changed the colour of the triangle filler) and some work on the Axe side, I got ...

SOLID DRAWING :crazy:

(http://img.removedfromgame.com/imgs/solidCube.gif)

Unfortunately, you won't be able to get solid drawing for now using the axiom, since I changed back the default colour of the triangle filler to black (it's just to show how easy it is, I only had to change 2 bytes in the axiom and add a mere 200 bytes in the Axe program). I think I'll made a tutorial on the technique I used (which is still very bad).

Last thing, I moved all the functions to the DISTR menu [2nd] [vars]. So I'll have 15 fields left for commands (including the ones already used) :thumbsup:

Anyway. I attached AXMJH3D.8xv, which is the axiom, TEST.8xp, which is the source of the program running on the first screenshot, and a readme.txt, which you will need to read if you want to program with AXMJH3D.

As ever, all of these screenshots are made at 6Mhz. And as ever, share comments :)

I was wondering if orientation is stored in x,y,z angles currently. If so do you plan on migrating this to a full 6dof system? (Where orientation is stored in matrices, as opposed to a matrix being generated from updated x,y,z angles every frame ... if that makes sense?)

All drawing commands now takes an additional argument : 0 for black drawing, 1 for solid white. This makes solid display possible for you guys :thumbsup:

Good news :)

I wrote a perfectly working (100% success rate :thumbsup:) clipped triangle routine in Axe, and I'm working on editing the current ASM triangle routine :D  It's not too much things added, so you'll probably see it in ASM before next week.

(http://img.removedfromgame.com/imgs/clippedTriangle.gif)

It's going so fast that I don't have the time to release the button while it draws another triangle :P

Also, ben_g and me are working on a SortFaces(Zarray, facesArray, outputArea) automagic, to sort your faces to handle occlusion and make your life easier ;D

I can't write a proper clipped triangle. I don't know why, but this just doesn't want to work. I re-read the code many many times and still can't see the error. If you guys wanna help me with this, here is the complete AxeJh3D code at pastebin (http://pastebin.com/DyK1MiGZ).

Actually, clipping works perfectly with y < 0, y > 63, x > 95 but not with x < 0. I also attached a small Axe program to test the routine, if you want to see what's wrong or to fix it.

I need to explain some things related to the way I draw the triangle. First, I constantly use 3 variables : startX1 and startX2, two 16.8 numbers, which refers to the left and right pixels of the line to draw (because I draw the triangle with horizontal lines), startY, which is the Y coordinate of the line. I also constantly add two 8.8 variables to startX1 and startX2, namely dx1 and dx2, which are the slope of each side (dx1 is updated during the process to the slope of the 3rd edge of the triangle). I did it that way because with only 8.8 startX*, the triangle went too fast from 127 to -128, making the triangle being drawn wrongly. So by doing that, my goal was to fix that error, since it's harder to go from 32767 to -32768.

EDIT : with help from Runer112 on IRC, we made it that the triangle is properly clipped when x < 0 ; but the 127→-128 thing still appears, so the problem is not solved yet.

How do I compile the program? If I try to, the calc just shuts off then I get a RAM Clear ???

Since you are clipping triangles in 2D, you will need to see if the length of any slice is > 128 and dont draw if this is so. This usually means that the triangle is ultra close to the viewer anyway so should be ok.

If you are wanting to make an indoor room however, you might need to look at 3D clipping techniques.

How that works? I understood that MatrxRot prepare the matrix, that RotVertx rotates coordonates with the matrix and ProjVertew give us some coords, but why when using on a simple point it gets crazy rotztuons?

Code: [Select]
`0->IRepeat GetKey(15)CalcMatrx(I,0,)RotVertx(10,0,0,L1)ProjVertx({L1}^r, {L1+2}^r, {L1+4}^r)->APxl-On(A^256, A/256)DispGraphClearDrawI++End`Why do I get a point that goes berzerk and go erratically?

You need to add an offset to {L1+4}r (150 works fine) so that the point doesn't project right at your eyes, but a little further. I'm very glad to finally see someone trying to use the axiom ^^

I just noted that Quad should need vertices in order, right? Oh, and xhat's the offset for quad?

Quad( will need the inputted vertices to be ... inputted as follows :
Code: [Select]
`1---------2|         |4---------3`Rotated in any way of course.
You use the function in that way :

OFFSETS is a pointer on 41-bytes values, which are multiples of 6 : they will be added to TABLE, which is a pointer on a table of 6-bytes vertices (don't forget to rotate them before drawing). COLOR is 0 for black and 1 for solid white. Example :

Will draw a white quad out of the 4th, 8th, 1st and 2nd vertices of the vertices table situated at GDB1ROT.

EDIT : not sure about the multiples of 6, I guess you can just test it. Maybe in the example it's just Data(4,8,1,2), I don't remember :/

Ah, it's a pointer to a vertice table, isn't it?

Yeah, exactly. This table is intended to contain rotated vertices, not the original ones, because the Quad function only does drawing.

Would it be possible to obtain the source code?  ;)
