Ask for help / Re: Bad viewport lag in Windows 7

« on: November 30, 2011, 01:03:34 PM »

Looks like the problem is very much reduced having increased the VM and rebooting, it's pretty workable now. Of course if anyone still has any ideas about how to get the best out of this system I'd be eager to hear them.

Ask for help / Bad viewport lag in Windows 7

« on: November 30, 2011, 12:56:14 PM »

Hey guys,

It's been a looong time since I posted here. I should come here more often.

I have a problem. I recently upgraded from XP to Win 7. In XP rhino worked like a charm, however I'm getting real bad lag issues now. All my hardware drivers are up to date so far as I know, and I've increase virtual memory a bit but to no avail. Here are my PC specs:

CPU: Intel Core 2CPU 6700 @ 2.66 Ghz each
GPU: Nvidia GeForce 8800 GTS 320 Mb
RAM: 4Gb

Can anyone help? I can work with this to get to deadlines but it's going to drive me insane if I can't fix it.

As always, thanks guys

Will.

Your method sounds perfectly effective, sounds like your machine is holding you back. If it can't handle arrays and booleans and renders, maybe it's time to consider upgrading .

Modeling / I need a second opinion....

« on: February 04, 2009, 06:23:09 AM »

Hi guys,

Sorry I haven't been around for a while, I guess things have been busy and I haven't had any problems in rhino lately haha.

As you all know, even when you are comfortable with the programme and feel capable of modelling almost anything, sometimes you have to re think the way you do things and entertain the possibility of there being better methods.

I do a lot of modelling for rapid prototyping, and today my model started getting more complex and the PC started slowing down alot (not my PC, a college PC, my machine is brilliant and eats everything for breakfast.) So I asked my tutor if there was a way to assign more memory or power to the programme. He didn't know, but concluded that my modelling methods were perhaps to blame. When I am modelling I often use booleans and trim functions, as I find them very useful and quick in creating solid shapes. My tutor said I should avoid booleans as they are "difficult to control, and more random" and that trims "don't actually remove the trimmed surface, which means there is alot of extra information and it's bad for rapid prototyping." For example, I am modelling a ship which has a flat supertructure side and lots of portholes. I built the surface, and then booleaned the portholes out (which killed the PC.) My tutor said I should have used a planar surface to crate the wall and holes, then extruded and capped all the portholes. Though he didn't demonstarte this. But surely, if "creating meshes" is taking time, and the end surfaces you are joining are the same it will take just as long no matter how you moedlled it?

Am I correct in using booleans and trims when modelling, or was my tutors advice....not so correct.

It seems odd that trims are "bad," sometimes there's no other way to model something surely?

Right I'll keep this short because frankly I found your last post to be grossly negative and disrespectful. Rhino is not meant for mesh editing. You are wasting your time mate. It does not have smooths, you cannot boolean meshes and so on and so forth. It is a NURBS program, polys are just a conveniance for exporting.

If you want to learn how to model landscapes in nurbs you have to start with the basic models like calipers. The skills are trasnferrable. If you dont have the patience then you wont get very far. No one is going to tell you how to get perfect results off the bat, you have to find out for your self through experimentation and trial and error sometime. But starting with a mesh is a waste of time. Try starting with a map with contours and some lofted curves and you might get some results.

Oh by the way, it doesn't matter how low the poly count is, you can't convert polys to nurbs. Its a mathematical impossibility, you can't do it. Ever.

Ivan runs and maintains this site for no profit and he gives his amazing knowlege to us without asking for anything back. He does the best he can, and you should be more courtious. You won't recieve much help if your aren't.

Maybe there is a better site, I suggest you go find it.

Ok, I'll start at the beginning . First off, there are fundamental differences between polygon and nurbs geometry. Polygon geometry uses cartesean coordinate space to "join the dots" between points in space (verticies) to create a shape (surface.) Nurbs work differently. Their shape is determined using curves rather than points, this makes them very much more complex than polys (hence why it is impossible to convert nurbs to polys, but because the surface info is there they can be converted to simpler polygons.) Rhino is simply not designed to work in polys, if you want really good poly modelling tools try 3dmax or better still maya. Rhino allows you to make your models in nurbs from curves or lines that you draw, the if you want to you can convert to polys at the end. However the mesh will be irregular and very difficult to edit. The modelling facilities in rhino are a collection of tools and functions that are designed to allow you to create nurbs models quickly and to a very high degree to accuracy.
You shoulkd work through one of Ivan's tutorials (like the calipers or hair dryer) on the front page and you'll understand what I mean.
There's no real how to with landcapes, you'll most likely find that tools are helpful in some unexpected way. Try modelling basic things first, then apply what you learn to your own projects. You'll get there if you work hard .

Hi there,

We get this question alot, and it's probably because people go into rhino without knowing what different kinds of workflows different programes use. This is perfectly forgivable, there's enough to take in when you start out as it is.

Rhino handles meshes for conveniance more than anything else. It allows you to create meshes so that you can rapid prototype them, CNC them etc etc. But rhino is NOT a polygon modelling program. It's whole point is that it is a truly amazing nurbs modelling program, probably the best. The reason it is so good and so cheap is because it is so specialised.
If there were a polygon modelling and editing suite inbuilt then it would lose its specialism and we'd have to pay much more for it.

The thing is, you can do anything in nurbs that you can do in polys. You want to build a landscape out of contours with spot heights No problemo. It depends only on what you are actually using your model more. If it is only for rendering then it makes no difference whether the model is made using polys or nurbs, and if you have to output polys then it can make great meshes from your finished nurbs model.
Have you explored the modelling facilities at all ? You will find a method thats suits what you want to acheive, I guarentee it.

But if you really want mesh editing then rhino is not much good for you.

You can always delete history every so often if you are happy with what you have, this will help to prevent Rhino slowing too much.

Yeh setting the mesh to "smooth and slower" will help as Scott said.

I do tons of laser cutting in rhino, the drawing tools are really easy to use, and If you use autoCad they will feel familiar. Though I usually have to export to illustrator to weight and color the vectors. But yes, rhino will serve you well.

Well in that case you have two options. Assuming that you aren't animating it, you could define the render environment as white or green or whatever bright solid color. Then you can take your renders into photoshop, cut out the green and stick an image behind it.
Alternatively you could map a plane with a bitmap. Search for "mapping" in help and you will find guides on how to do this. This would work with an animation too.
