Re: [osg-users] Visualization of billboards depending on pre-conditions

Hi, Hartwig, I think you have to use multi-pass rendering to make this special depth test work. Here is my idea, pass 1: render foot separately to a texture without depth test, and writes only 1 or 0 to the texture, 1 while the pixel is part of foot, 0 otherwise. pass 2:

[osg-users] Visualization of billboards depending on pre-conditions

Hi, I would like to show a complete billboard when a certain part of the billboard is visible. Although other parts may be (partially) hidden by other items. Example: assume that the billboard is a sign consisting out of a foot, pole and the sign itself. Whenever the foot is visible (depth

[osg-users] Visual flicker when using multi-pass technique, related to frustum?

Hi, I have two graphs that have completely different content. One is used for initialising the depth buffer, the other one for showing the scene. Code: visibleGraphPtr = ... depthGraphPtr = ... depthGraphPtr->getOrCreateStateSet()->setAttributeAndModes(new

Re: [osg-users] How to render (sub-)graph only into depth buffer?

Hi, isn't it also a viable solution to use a slave camera that just pre-renders its depth related scene into the depth buffer and use the main camera to render the real scene afterwards? Both cameras operate on the same context. Though I do not know whether it causes any problems. Cheers,

Re: [osg-users] I made the libRocket GUI library usable with OSG

HI Denis, I cannot comment on specific of librocket. If you want to use 2D elements in a 3D scene the standard way of doing this is to use a Camera that sets the project and view matrices to creates a 2D projection. The osghud example illustrates how to do this. Perhaps this would be useful to

Hi Robert, Implementation librocket, which are published them in order. Problem is only in the GUI display is on the node that rotates around the axis XYZ. Myself but needs to appear as a 2D GUI, something like over the base OSG viewport. I should if you would like to display scores and other

Hi Pei, You can disable the build by just setting one the include vars to empty: cmake . -DFFMPEG_LIBAVCODEC_INCLUDE_DIRS="" make W.r.t ffmpeg API, it's constantly changing and breaking backwards compatibility, it's the single worst offender of all the 3rd party dependencies that we

Re: [osg-users] Solar system in OSG or OpenGL?

Hi Chris, Just my two cents: As a beginner, when I started to use OSG, learning from the beginner guide and the net tutorials, I was quickly able to get a good rendering. However, due to my lack of knowledge in OpenGL, at some point I get stuck in m development. So I've decided to buy a book

[osg-users] Solar system in OSG or OpenGL?

Hi, I have been given an assignment at University to build an interactive solar system. We have been give a choice to build it in OSG or OpenGL. I have never used either and a beginner in C and c++ but I have time to research and learn the languages properly. But before I start I wanted to know

[osg-users] [build] Disable FFMpeg while building OSG?

Hi, Trying to build OSG from source, under Ubuntu 16.04.1, with GCC/G++ 5.4.0. It seems there is NO Option for FFMPEG (Enable or NOT), but it automatically look for FFMPEG related directories by default, and found the following: Code:
