Re: [osg-users] Implementing clone() on class derived from osg::Geometry and osg::MatrixTransform

Hi, clone method is virtual and should return osg::Object*. you can dynamic cast (or even static cast if you are sure) to PiGeometry*. How can I force the program to call PiFaceGeometry::clone() if this is only a child of object, on which I called clone()? I am sorry If this question is

Re: [osg-users] Texture image memory leak issue

Hi, if you check your program on memory leaks (for example with visual leak detector) and don't find any leaks, it's probably fine. The problem is in memory management. There are many things that can cause increasing memory: 1) Creating any type of object or buffer on GPU is slow operation, so

Re: [osg-users] OSG and OpenGL rendering does not coincide

Hi IIRC osg by default tweaks projection matrix depending on window aspect ratio, you can set desired behavior with camera-setProjectionResizePolicy(...) Also you can check if viewport is actually same (there can be some difference because of window decoration or something) 01.12.2011, 23:33,

Re: [osg-users] (no subject)

Hi, Short answer: there are no simple way, You should get all drawables, grab all primitivesets and set instance count for them, write shaders that make use of instanceID to calculate vertex position. also with instanced drawing you should disable display lists, so for performance reasons make

Re: [osg-users] User clip planes and shaders

Hi If you need to get same result as opengl FFP, you should add following line in your vertex shader: gl_ClipVertex = gl_ModelViewMatrix * gl_Vertex; IIRC you need #version 120 to use this. Then all clip planes enabled via glEnable would work with shaders 07.12.2011, 22:36, Dave Jones

Object rotation is the last piece of this puzzle. When on object is placed on a geocentric terrain using the methods outlined in this thread, the object always appears to be oriented correctly upwards with respect to the center of the earth. However I'm not sure how it is being oriented with

[osg-users] attachMoveCallback memory leak?

Hi All, testing my code I realized the following code generates memory leaks. Code: osgWidget::Canvas w(test); w.attachMoveCallback(); BOOST_CHECK_EQUAL(true, false); If I remove the attachMoveCallback() line I don't have leaks. Lookig at OSG code it seems the callback object is insert
