Re: [osg-users] How to prevent OSG linking against Desktop OpenGL

Hi Daniel, We are also using OSG together with modeen shaders like geometry shaders. We have to do a lot of online presentations and online support. This works perfect with TeamViewer. May this be an option for you? On 9. September 2016 18:04:13 MESZ, Daniel Neos wrote: >Hi, > >my Applcation ma

Re: [osg-users] Detecting when a texture is to big for graphics memory

Hi Allister, I have a comparable situation in my software. Displaying huge textures. I got help from the list recently and now it works like a charm. I split the texture in small tiles and assign them to textured quads. The quads are arranged to form a huge plane. The trick is arranging them in a

Re: [osg-users] Improving performances

Hi Alex, I'm doing simulations of textile structures and work with yarn objects being deformed according to Bentsen stretches etc. The number of triangles is also extreme. I have a COUPLE bound version doing the geometries by CPU threads and a second version working with geometry shades. Both ve

[osg-users] When gets the view matrix of a camera ipdated

Hi all, I have written some classes for special effects like ambient occlusion or shadow. All those classes are using their own prerender cameras. The cameras use the initial draw callback for updating their view matrices by using the main cameras view matrix. Unfortunately it looks like the ren

Re: [osg-users] Draw geometry on demand

Hi Tyler, if you set a new vertex array or change an existing on in a drawable of the scene graph it should show the changes in the next render frame. There is no need for doing something special. Maybe you have to set the modified array sorry. That's all. On 10. Juni 2018 09:53:34 MESZ, Tyler

Re: [osg-users] osgQt + OSG 3.6.2 Status

Hi Joshua, I fully agree with you. We are developing commercial software and started with plenty of years ago. About 10 years ago we started to use osg and embedded osg view into a qt widget based on the osg-qt project at that time. It worked smoothly since then. Now we are on the latest release

Re: [osg-users] Off topic question and request for ideas

Hi Chris, it is just the surface and borderlines rendering with the filaments. No dynamics. On 14. Dezember 2018 21:51:48 MEZ, Chris Hanson wrote: >Are you talking about the rendering aspect or the cloth dynamics >simulation >aspect? > >On Fri, Dec 14, 2018 at 3:35 PM Werner Modenbach > >wrote:
