3D Cube with canvas with rotation

[Bee-Ant]

Yes I'm experimenting 3D stuff with canvas. And here's the second demo.
Thanks to fuzzy for the elipse code (sin,cos,degtorad)
You can use this stuff to make 3D room
Enjoy.

This demo sucks!

Haha just kidding!



Its interesting though, what makes it slow down is lots of draw, an issue with the canvas. When i look more top down at it, it rotates fast, but from a more side view, its slow.

It lends some possibilities to the raycasting demo from before, that if you can minimize the drawing the canvas must do, by using the bitmap renderer instead, you could get some good speed from it.

Perhaps if you had texture sets, with all the sizes,....i mean, in wolfenstein, the walls only rotate on the x/z axis, but never the y axis.(i'm calling x the angle rotation and z is the depth(zoom) of the object). If someone can put all these puzzle pieces together, i'm sure there's a way to make a fast 3d program with no need for gpu.

Basically, take Feral's 3d examples which ran fast,combined with yours which are more convincing....perhaps it can be done!

[Bee-Ant]

I didnt know that it slow. Because it ran well on my lappy from any side of view.
Feral's 3D...that 3D box platform right?

Hmmm...first of all, I'm still new at this stuff. So I still dont know how to read and render bitmap. But yes, I will think about the perfomance by reducing the drawing.

Great job using the ellipse example for this. That is the sort of logic that a good programmer uses. The code underneath is very much the same, but the appearance is quite different.

[Bee-Ant]

Yes
I use 4 points x y that decided by 4 angles(0,90,180,270). Connect point 1 to 2,2 to 3,3 to 4,4 to 1 using moveto and lineto. This is for basic square without filling.

Ummm,one thing that im unable to do fuzz, how do i fill the top square of the cube?I could make some points that follow line 1-2(the line that formed of point 1 and 2) but i cant pull lines to fill the top square.arkghhh...my cube isnt perfect after all...

This all sounds exciting!

You be able to edit this with color and make a rubics cube game of some sort? hope this was helpful somehow.

[Hblade]

Exelent stuff, bee :3

[Hblade]

It's amazing, nice job

[Bee-Ant]

You just found it??
Thanx anyway

[Hblade]

Well, uh.. no but I wanted to compliment it again >.>

How the ? do you make my little tetrahedron rotate vertically then?

[Bee-Ant]

do you make my little tetrahedron rotate vertically then?

You are asking my help to make it be able to vertically rotate or what?
