Re: [osg-users] [3rdparty] osgOcean collision detection

Hi, it seems to work fine but I am still testing. For big models of height 2.0 and more works fine, for smaller height models there are frames that goes above water, just a little though and also on some other frames just below the surface, especially on high wind speeds. This behavior might

Hi there, this is a quick response as i'm on my pda If you look in the implementation of shapedrawable, drawcylinder function, i believe the vertex locations for cylinders are calculated on each draw, using sin and cos! Also note the matrices for positionattitudetransforms are computed per

Hi Dimitrios, Glad to hear you got it working. I have a couple of further hints for you. You may find that the accuracy is improved if you use _oldFrame without the increment. The variable name is a little misleading as it is actually stores the id for the current frame, if you look at the

Hi Felipe, If you are needing to populate your world with lots of cultral data like roads, forests, rivers, towns, cars etc. then you'll need a 3rd party modeling program, or come up with your own scheme for inserting the extra models onto to your prepared terrain. Given you are doing a final

Hi Ugras, What you ask is slightly strange, and I apologies if this reply appears too patronising - it isn't meant to be! OSG is basically a rendering package; it just draws things. To try to interpret your question sensibly: 1) Can OSG import FEM meshes? I imagine that if your mesher can

Re: [osg-users] [3rdparty] change ocean height

Hi again, It works well, but with the skybox images that come with osgOcean, if you lower the ocean surface past a certain point you'll start seeing black. That's because the skydome images are cut off below the normal horizon, which should generally be z=0. This was not visible before, but

You'll need to debug this yourself. Here's how. After you add the Material and StateSet, dump out a node file and do the following: 1) Check to make sure your Material and StateSet were added correctly. 2) Look at child nodes and make sure they don't override the Material you set. 3) Make
