That’s both sick and wrong.



I’ve been working with modeling and rendering software (oh, and animation) for about as long as I’ve been using Xara Designer. And I’m still a journeyman at both.
As a “Roaming Moderator” on TG, I think I could get a little more enthusiasm and participation here because 1.) 3D is really cool. Has everyone experimented with Xara Designer’s Extrude too and/or the standalone animation program?

2.) Getting into professional level 3D will not break your budget. While Cinema 4D, 3D studio and the like have driven their prices up to two to three figures for a subscription (I detest SubscriptionWare)—Blender is free, always has been, and while you need t buy a $eparate module to do particle effects, Blends comes with a rather excellent fluid dynamics, explosions, clouds and other particle effects. It’s rendering engine is pretty darned good, too—I’ve been using Maxwell Render forever, and I have to hand it to the collaborative effort that goes into Blender.

3.) My third reason for typing all of this here is that increasingly, the companies who manufacture mega-capable programs with industrial-strength price tags are creating “lesser Gods”—free versions of the complete programs, with a limited, but not terribly crippled feature set. You can download “starter sets” from 3D Coat, zBrush (now part of MAXON/Cinema4D), and AutoDesk, all sculpting programs, with export options such as OBJ, a very commonplace file format for 3D.

Also, you might be able to find Adobe Dimensions, currently woven into Illustrator, for $3 or so on eBay, as orphanware goes. The neat thing about Dimensions is that it can render and extruded shape and a lathe one (think of a potter’s wheel) as vector shapes, not bitmaps as Xara Graphics produces. You might even be able to find a copy of CorelDRAW version(s) 2 and up for a pittance online (I’m thinking search Amazon) because Corel Corporation tends not to burn its back inventory with the release of a new version.
This is a sufficiently long, hopefully not excruciatingly long re-introduction to this forum. By all means, ask away! How does one begin conceptually? How steep are learning curves? That sort of stuff.

I hope to see y’all along the x, y, or z axis,

My Best,


Gary

Gary, thank you for filling what has been a 3D void.

I have Blender (for free, as you said) through use of PortableApps.com so it runs from a stick.

I have Xara's 3D Make7, which should be free as MagiXara have not updated it for a decade.
It produces animated GIF but nothing else that I know of to bring it into my XDA.
I appreciate that many 3D graphics will end up being a one-way street as once it is in the XDA, it stops being editable - unless you know better.

I have the most fun with ZBrushCoreMini 2021.
I still don't know how to excavate a blob.

No mention of 3D CAD or of MS 3D Viewer.

I'm sure I've other apps just waiting to be released.

Hi Acorn—

I commiserate with you that there doesn’t appear to be any easy way to “Drill” or “excavate” into a surface in zBrush mini core. If there were a negative value possible for the “pulling” tools, then you could push and displace an area, as you could in Sculptris, which was a free program zBrush bought and then made un-free ☹. If you look around, you might be able to find a copy of Sculptris, and as with any program that has any worthwhile features, you can export your results to something exchangeable with other programs…OBJ is not as robust as FBX, but but Sculptris and Mini core can export to OBJ.

That said, I think with the exception of brush tools found in larger modeling software (Cinema 4D comes to mind), there is another approach: Boolean operations. Boolean merging, subtracting and so on should be familiar with Xaraist…it’s just that the operations are performed on 2D shapes rather than 3D objects in modeling programs.

The attached image is my attempt at poking a hole clear through a sphere, and mostly failing, using Sculptris, and then and example of Boolean subtraction to get a “hole” in a primitive.

I think I’ll try to get into what a parametric surface is in my next post. Just about all the modeling programs out there (not CAD, but modeling) approximate a surface, and you crank up the resolution to make smooth surfaces. You’ll see straight vectors around a sphere, for example, that has a very low approximation of the surface.

My Best,

Gary

Thanks Gary, it's not as scary as I thought.
At its simplest, an OBJ file and a MTL file with reference to texture files.

I have been rendering into a web page using Three.js but it is a shedload of code at the moment.

Early days.

[Acorn]

Here is my approach to get a Blender file to render in a web page:

• Unzip THREE - Windmill.zip
• Add & into the just-created THREE - Windmill_xar_files folder.
• It is messy as TG would accept too large a file.
• It is not my design but i kept if to line up with the following tutorial.

I worked through most of https://r105.threejsfundamentals.org...-load-obj.html to get something that worked.

Changing the unpacked .Blender files was tricky to say the least.
Getting them to play nice in Xara was harder.

I failed to render the back of the sails as I think I lost one of the textures.

I finally discovered that you cannot animate .OBJ files as everything is one lump.
I was amazed that the texture files are so big. The XAR file is all of 24kB.
I now have a use for Filer Forge 11 that I purchased a few months ago.

Moving on to gLTF files and learning about textures and texture atlases.

You've outdone yourself, Acorn.


That is, I'm completely baffled over what you did: your method, as you described in your link above, is intended to allow a Web page to feature an object, not just as an image, but one that can be viewed from many angles? Not sure how Xara Designer enters the picture. :) !

I've seen rendered objects that can be rotated and stuff in (almost) real time on free and commercial model stores on the Web. Here's one such if this is related to your work...

SketchFab usually free models



That said, I took the liberty and I hope you don't mind, of doing something leagues less ambitious; I just rendered the windmill, with JPEG image maps attached correctly, did a little color correction and found the appropriate Getty image. The wavy reflection is Flaming Pear's Flood filter.




Both your approach and what I do are valid and interesting things to do in a 3D realm.

We have almost 100 hits in three days and no one has hopped in yet. Folks, post anything related to 3D that you like (SFW, okay?), that you'd like to talk about, and help us breathe some air into this forum.

I will try tomorrow to post a somewhat advanced tutorial on how to use the 3D Extrude tool to create a toy train.

Here is my approach to get a Blender file to render in a web page:

I'm in awe Acorn. Great stuff. I've dabbled with Blender over a few years but I find I'm forgetting more than I can remember.

[Acorn]

Gary, I decided i wanted to present future 3D model that I design into a web page. I didn't want to just output static views (planes or cars).
My approach allows the viewer to zoom, pan & rotate without the need of a rendering engine, application or other web resource.

Here is what I did, published on-line: http://acorn.xara.hosting/windmill/.

I like your placing of the windmill against a image background.
I was working up to the background being a cubemap and also to animate the sails.

I have a friend who designs totally immersive aircraft simulators where you can make the cockpit transparent to export the wiring loom for maintenance or render every room in an apartment block for sales viewing where the cupboards open and the washing machine cycles.

Yeah. That's beyond me, Acorn. I definitely appreciate what is for me an extraordinarily elegant for a custom solution! When I want to reveal more than a static view, I animate. I tend to like to do "push-throughs" at low angles and such.

I want to thank you so very much for opening our 3D discussions and advice in a direction that I'd say is mind-blowing without fear of contradiction!

As I'd mentioned earlier, I'm going to break out of this thread to offer a PDF tutorial because multiple screen caps and multiple posts suck. Focus is the 3D Extrude tool, just a jumping off point (or "climbing aboard") for other explorations.
