: Re: [osg-users] Node needs to render at least one pixel
Hi Phil,
For the distance from the eye point/view Try:
NodeVisitor::getDistanceEyePoint(Vec3)
NodeVisitor::getDistanceToViewPoint(Vec3)
ViewPoint and EyePoint are usually co-incident, but in some effects like
shadows the eye point

Hello Philip,

node-setCullingActive(false) on the MatrixTransform whose child is the
image, but with no noticeable change. Does this setting affect a node's
children as well? I've checked my
Hello Philip,

I don't think mipmapping will solve the problem, because

Hello, all:
I have an object in my scene that I need to render to at least one
pixel. It's generally a fairly small object (in a 3-D scene). It
renders fine up close. I need to force it to render to something (at
least one pixel) regardless of its distance from the camera.
I have thought of
Hi Philip,
Have a look at osg::AutoTransform, if this does't fit then just roll
your own cull callback to do the job, or write your own custom
Transform node.

Hello Philip,
I have thought of artificially moving it closer, or scaling it larger,
but I was wondering if there is, instead, some attribute I can give it
that says, render me even if I'm small.
I imagine you mean that you don't want your node culled even if it's
very small. You can turn
