Re: [osg-users] Modern GLSL and OSG

NOTE: the current development version of ANGLE is targeting OpenGL ES 3.0, if you want to be more up to date. I am not sure about its level of completion and stability though. Maybe you can find more complete (commercial?) virtualization solutions to run the DX backend. Also maybe Wine is

Re: [osg-users] Modern GLSL and OSG

If you're using Windows you could try building OSG against ANGLE and limit yourself to the OpenGL ES 2.0 API feature set. Here you can't accidentially fall back into using deprecated (fixed function) features because these have been stripped from the API. There would also be plenty of books about

[osg-users] Modern GLSL and OSG

Hi all, I was wondering if anyone can make some suggestions as to resources that are useful for learning GLSL in modern OpenGL (say, 3.0+) with a specific focus on use with OSG. My existing GLSL knowledge is weak compared to my general 3D knowledge, and mostly dates back to the early days

Re: [osg-users] Modern GLSL and OSG

Hi Christian, Many thanks for the interesting suggestion. :) My main development environment is Linux-based, with a secondary virtualised Windows development environment. Due to the visualization (VirtualBox) I don't believe I can do much in the way of development with ANGLE due to its DX

Re: [osg-users] Modern GLSL and OSG

Replying to myself with what I have managed to figure out so far to provide some information in case it comes up in a search. I can't vouch for the accuracy as this is still new to me. Anyway: - Compile messages end up being sent through the osg::NotifyHandler mechanism. - Shaders don't
