[osg-users] Byte sizes of various objects

A discussion came up this week about the overhead and memory consumption of various OSG objects, relating to the possible indiscriminate use of them. It turned out not to be an issue, but in the process of investigating, I quickly measured the in-memory byte sizes of a few common OSG objects.

One of the machines I've been exposed to this week is a Dell Precision M90 laptop with a Quadro FX 2500M. I guess they use them for on-site demos sometimes. Now, normally a Quadro is a pretty desirable card. but this one is doing some weird stuff in OSG that I can't identify. The model being d

Shortly after my last post, I got moved away from working on a HUD, before I had actually solved the above problem. I've spent the better part of today working on this again, and have been unable to get a valid BoundingBox from my osgText object. Here's the code chunk in question: Code: /

I have found it much safer/easier (in the long run) to not collapse the namespaces. It's a lot of trouble to go back and correct the problem when you start integrating other toolkits. Just my 2 cents worth. > On 13 April 2010 17:12, mas oug wrote: > >> Hi, >> Just curious, I noticed that in a l

Re: [osg-users] Use namespace...

Yes you can, however OSG uses simple names that will likely also be used in other projects (e.g. Array, Node, Group etc.) so it's quite likely you'll get name conflicts if you use another library which uses the same class names. I've had developers making similar complaints to me, so as a compromis

Re: [osg-users] Render to VBO?

Paul, Thanks for your input, but I think you've misunderstood me. I already use VBOs quite happily. The question is whether you can use a pre-render pixel stage to render directly into the vertex buffer (the technique is sometimes abbreviated RTVB); i.e. to use a fragment/pixel shader to populate
