[osg-users] SmoothingVisitor normals doesn't seem right

2015-01-27 Thread Ash Pat
Hi, I am trying to use the SmoothingVisitor to generate the normals. I am not explicitly setting the normals array. However, when rendered it appears as though the normals generated are flipped. The geometry consists of triangle and quad primitives. I tried it in two ways. Code:

Hi, I got it to work. There were a number of things that I was doing wrong. - The frames were going by too quickly. So a simple wait timer of 500 ms slowed it down. - There was an extra instance of MatrixTransform which was really a typo. That is why the the initial position didn't seem to

Hi, Thanks for the suggestions. I think the idea in both the responses was to get enough frames so that it doesn't complete in a fraction of a second. So I tried it but it still doesn't seem to work. I even inserted a wait time of a few seconds between the frames but it didn't help. However,

Hi, I'm trying to simulate a rigid body motion (translation and rotation) based on some Physics. Basically I have a number of bodies and a solve returns new positions for these bodies. I'd like to update the MatrixTransform associated with the bodies' nodes for each step which I'm hoping will

[osg-users] PositionAttitudeTransform - rotation and translation

2009-10-23 Thread Ash Pat
Hi, I'm using PositionAttitudeTransform to add multiple instances of a geometry node. It appears that the rotation and translation are specified with separate methods, setAttitude() and setPosition() respectively. Is that correct? Can it somehow be done with a single matrix like in homogeneous

Hi, So I tried the MatrixTransform but it seems to skew the geometry. When I tried a matrix shown below, I was expecting a simple rigid body translation. But instead I got a display with massive extents. osg::Matrixd mat; mat.set ( 1, 0, 0, 0 0, 1, 0, 20, 0, 0, 1, 0,

[osg-users] How do I toggle the osgViewer::Viewer full screen mode?

2009-10-07 Thread Ash Pat
Hi, I'm new to the OSG and just starting out with some simple examples. The osgViewer::Viewer by default displays in full screen mode. But in my application I want it to be a smaller window by default. How do I do that? I found the event handler WindowSizeHandler which has the facility to
