Re: [osg-users] How to properly transfer texture coordinates in geometric shaders in Shader #130 version?

I just wanted to add that it is a popular opinion among the industry that Geometry Shaders were ill-conceived architecturally and suffer unsolvable performance-blocking issues. There are alternatives of various forms which have their own complexities, but just in case you run into perf problems

Hi, have a look here MuseOpenIG/Plugin-GPUVegetation at master · CCSI-CSSI/MuseOpenIG · GitHub ... This is code for generating forests with geometry shaders. It might give you better clue On Sun, Dec 13, 2020 at 7:08 AM

sorry, the screenshot is wrong. It should be samplerU. I'm basically not sure how to get texture coordinates into Shader::FRAGMENT in Geometric shaders. 在2020年12月10日星期四 UTC+8 下午11:13:21 写道： > What error are you getting? > I do see an undefined "samplerY" in there. > > On Wednesday, December

What error are you getting? I do see an undefined "samplerY" in there. On Wednesday, December 9, 2020 at 9:03:47 PM UTC-5 mirr...@gmail.com wrote: > env is win10 osg3.6.4 GTX1660 > [image: QQ图片20201210095944.jpg] > > osg::ref_ptr createProgram() > { > osg::Program *program = new
