[osg-users] isVertexBufferObjectSupported() ?

Hi,i am trying to make a terrain editor. here i wanted to implement my own drawImplementation of geometry but i could not get manage. i always get state.isVertexBufferObjectSupported() as false... when i ignore this false, i got another problems.. i think my problem is this isVertexBufferObjectSupp

Re: [osg-users] isVertexBufferObjectSupported() ?

Hi Ufuk, The OSG checks for support of extensions such as vertex buffer objects, and will osg::State is one class that does this, so if you are isVertexBufferObjectSupported() is returning false then wait for it there is very good chance that your OpenGL driver/hardware doesn't support

Re: [osg-users] isVertexBufferObjectSupported() ?

Hi, Actually i dont think it is about hardware or driver because i did a project similar to this with this hardware and it is still working on my computer. it returns true on "isVertexBufferObjectSupported()" but this project was made in like osg ~1.6. The function on Geometry was "virtual void dra

Thanks Robert, i know that you cant know the problem without seeing the code :) i just want to know that when isVertexBufferObjectSupported() function returns true or false? to use this support should i enable something? anyway now i will try to make a simpler example, then maybe i could show you

Re: [osg-users] isVertexBufferObjectSupported() ?

Ufuk, bool isVertexBufferObjectSupported() const { return _isVertexBufferObjectSupportResolved?_isVertexBufferObjectSupported:computeVertexBufferObjectSupported(); } If you have seen the code that checks whether extension is supported: bool State::computeVertexBufferObjectSupported() const {

Re: [osg-users] isVertexBufferObjectSupported() ?
