Hi J-S Some thoughts... - any ideas on exactly where you're bottlenecked? - if perception of cable width is critical, how are you ensuring the quads are orthogonal to the viewer? Billboards, adjusting the quad verts, viewer/quad relationship is fixed, etc? - quadstrips are converted to

Hi Mike I may have narrowed down the problem. It's not so much the arrays that are causing problems, but their usage. For example indexing an array like this: arr[ind] works fine for the vertex shader, but doesn't compile on the fragment shader, saying that the index has to be constant, so that

Hi Mike, Thanks for the pointer about the GPU pipeline, I'll check it out. So you're drawing 6x as many quads as necessary; that's seems a good rationale to learn geometry shaders! :-) That and moving texcoord generation off the CPU and into the vertex shader. I'm pretty anxious to try

Hi, First, please put some subject to your post. Maybe take a look into osgPPU (http://projects.tevs.eu/osgppu) this is a nodekit which is what you looking for. It helps you to make multipass (render to texture and then as input to next texture) in a very simple way, without creating
