[osg-users] VertexAttribDivisor -- should it be part of the VAO state?

. The divisor is really a property of the Array. I am thinking that it should be set in osg::Array and then applied in Geometry::drawVertexArraysImplementation. Hope to hear your thoughts. Glenn Waldron / osgEarth ___ osg-users mailing list osg-users

Re: [osg-users] How do I continuously read the mouse position as the mouse is moving, without a click event in osg

Kris, You want to install an osgGA::GUIEventHandler, override the handle method, and listen for the MOVE or DRAG events. DRAG fires when moving the mouse with a button down. Glenn Waldron / osgEarth On Fri, Feb 8, 2019 at 6:03 AM Kris Bartowski wrote: > Hi, > > I want to read

Re: [osg-users] Convert .earth file to .osg format

Steven, You should consider making a GDAL VRT. It's a format for compositing source files together into one virtual data source. You can build it by hand or use the gdalbuildvrt tool. https://www.gdal.org/gdalbuildvrt.html Glenn Waldron / osgEarth On Mon, Apr 29, 2019 at 7:02 PM Chris Hanson

Re: [osg-users] [OSG 3.6.3 Core Profile GL 3+] Weird clipping behaviour in Fragment Shader

GL_CLIP_PLANE0 is deprecated in GL3+ and unavailable in CORE profile. Instead, use GL_CLIP_DISTANCE0, pass your clip plane into your shader in a uniform, and use it to set gl_ClipDistance[0]. Example: https://github.com/gwaldron/osgearth/blob/master/src/osgEarth/ClipPlane.glsl Glenn Waldron

c4 gdepth; ... gcolor = color; gnormal = vec4((normal+1.0)/2.0, 1.0); gdepth = vec4(gl_FragCoord.z, 1.0); Notice that you will need to normalize the "normal" value so it's between [0..1]. Hope this helps! Glenn Waldron / osgEarth On Mon, Nov 11, 2019 at 4:20 AM Han Hu wrote: > Hi,

Re: [osg-users] Finding the edge of a frustum, or intersection with the edge of a frustum

convert your line's points into clip space by multiplying each point by the (modelview matrix * projection matrix). I successfully used this approach for graticule labeling in osgEarth. Good luck! Glenn Waldron / osgEarth On Fri, Nov 8, 2019 at 3:44 PM Brad Colbert wrote: > Hi, > >

Re: [osg-users] Render normal vectors to image

You're welcome. You might be able to use the osgDB::Registry::setReadFileCallback() method to intercept read calls. At that point you can generate your normals (for example run the osgUtil::SmoothingVisitor) and then return the result to the system. Glenn Waldron / osgEarth On Mon, Nov 11

Re: [osg-users] Setting a monochrome 2d texture from byte array

Sandy, Try this instead. You probably want normalized [0..1] data on the GPU, not [0..255] integers. img->setImage(w, h, 1, GL_R8, GL_RED, GL_UNSIGNED_BYTE, data, osg::Image::USE_MALLOC_FREE); Glenn Waldron / osgEarth On Tue, Nov 5, 2019 at 2:14 AM Steve Hardy wrote: > Hi, > >

Re: [osg-users] Image from shader

I think you want: gl_FragColor = color; Or, if you'd rather use the built-ins, get rid of your "out vec4 color" and write to gl_FrontColor in the vertex shader: gl_FrontColor = gl_Color; And read from gl_Color in the fragment shader: gl_FragColor = gl_Color; Glenn Waldron / osgEart

Re: [osg-users] vcpkg gl3+

Gijsbert, Using the default OSG build does NOT prevent you from using GL3 and GL4 features. However, it will not support a CORE profile -- for that you'll need to rebuild them yourself with the correct options. Hope this helps. Glenn Waldron / osgEarth On Fri, Oct 4, 2019 at 5:04 AM Gijsbert
