1. ## 3D Software

I have recently started a new hobby creating 3D shapes and proving things mathematically. I am not a mathematician by trade but a self seeker.

One of the things I am trying to do at the moment is to create a revolving cube on a screen, there is the problem, I try to 'depict' 3D solid on a 2D screen and therefore when creating a VB program I am not always using the original formula that I have created as I have to offset certain coordinates to give the shape depth and perspective. I therefore so wrapped up in the programming that I miss the beauty of the solid I wish to create. <!post=An example of an Octagon,410569>An example of an Octagon<!/post> .

To help me sometimes I create a model of what I want to do and this gives me ideas how to solve it, below you will see a model I made so that I could visualise a cube in space, the sticks being the x,y,z axis (red lines drawn in on photo to show cube).

What I am looking for is some type of software that can render my calculations so that I can see it on screen, any ideas?

A Google search for 3D rendering software will return lots of hits, for example Blender3D (free). Also see the threads starting at <post#=372918>post 372918</post#> and <post#=339802>post 339802</post#>.

Thanks Hans

I see I have a fellow 3Der in AlanMiller. I'll have a got at some of these.

In the early days of 3D computing there was a lot of talk about "the hidden line problem", where in a solid you have to "remove" the lines at the back which should be hidden by the solid bits in front. This took a lot of computing power, but since we have come a fair way along from the Z80 and the 8088, this is presumably now a trivial exercise!

Hi Jezza

Sorry for the delay at jumping in here. The Blender is quite an amazing piece of software, with huge capabilities. For your stated needs, it provides a quick & easy rendered view of your object(s), static or rotating about any axis you like.

But be prepared for a climb up a learning curve. Still, if I managed it ... Also, be sure to have a look at some of the sample files, to see what's possible.

Thanks Alan

I downloaded it yesterday and loaded it onto my home PC last night...... well three hours later <img src=/S/dizzy.gif border=0 alt=dizzy width=15 height=15> ...I realised that I had a lot to do to learn it capabilities, but I was very impressed.

During my search I also found Mathematica which is a mathematical solution. I am going to get a trial download to see what it does.

PS I note you have just been promoted to SilverLounger...Well done

Alan has been a SilverLounger since the 2nd of September; he is well on his way to becoming a GoldLounger!

Thanks Jezza. As Hans says, I seem to be on a roll through the noble metals of the periodic table. <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

Looking harder at your post, I get the impression that you'd like to control things through your own parameters and programming. The Blender doesn't really offer this kind of input, but The Persistence of Vision Raytracer does, through a fairly easy-to-pick-up scripting language. For instance, this image:

is the product of the attached POV script. This might be closer to what you're looking for?

This looks like a runner

11. ## Re: 3D Software

Yes, Blender-like stunning graphs!!! Real cool. Good find, Alan!!!

As for Mathematica, it's another extremely powerful package. I'm not sure it's intended for this kind of stuff, though I've seen it capable of doing so many, so diverse things that I wouldn't be surprised if it suits your needs. It's a truly amazing piece of soft, with an excellent documentation & help search. In the Wolfram site you (Jezza) visited you'll find a zillion things to keep you reading overnight.

Hi Alan

First I have to say thanks for any absolutely brilliant find in POV Ray. I downloaded it when you sent your last mail to the Lounge. I had a real play with it last night and was able to put in Bucky Ball co-ordinates and got the image below. This is the type of thing I was looking for, now I just have to learn animation!!!

Hi Diegol

Wolfram is an excellent site and I have got it on my favourites menu now. The trouble is, since I posted this request I have spent 2-3 evenings playing with POV Ray and Blender Mrs Jezza is getting rather upset <img src=/S/hiding.gif border=0 alt=hiding width=70 height=24>, better have a break and help her with the chores.

Hmmm <img src=/S/hmmn.gif border=0 alt=hmmn width=15 height=15>... I guess I'd better not tell you about the Anim8or 3D modeling and character animation <img src=/S/free.gif border=0 alt=free width=30 height=15>ware I just found then. <img src=/S/grin.gif border=0 alt=grin width=15 height=15>
