[osg-users] Re: Memory leak when using a pixel buffer to generate thumbnails

2020-06-23 Thread Robert Osfield
I can;t say what the leak will be from the code supply but I can say that creating a dedicated viewer, rendering a frame, then destroying really isn't an efficient way to go about generating a thumbnail image. Rather than than debug a dubious approach I'd suggest you leave it and try another

[osg-users] Memory leak when using a pixel buffer to generate thumbnails

2020-06-23 Thread Brian Hutchison
Hi Robert, I am using code extracted from the osgscreencapture example to generate small thumbnails of loaded shapes. It all work is very nicely except that it is leaking memory on each usage. I have commented out our code and based on that and a few other tests I am fairly convinced that the

I fixed it.This needs to be changed to the following code. osg::ref_ptr quad_coords = new osg::Vec3Array; // vertex coords // counter-clockwise quad_coords->push_back(osg::Vec3d(0, 0, -1)); quad_coords->push_back(osg::Vec3d(tex_width, 0, -1));

hi, I don’t change the color to make it dark I want to express that it darkens naturally as time passes by the influence of light. 2020년 6월 23일 화요일 오후 3시 55분 40초 UTC+9, OpenSceneGraph Users 님의 말: > > Hi, ? > > > > Simply set the fog-color to a darker color? > > > > *From:* osg-users > *On
