[osg-users] Matrix multiplication order

Hi everyone ! I don't get why in GLSL you transform a vertex like this: Code: vec4 result = matrix * vertex; While in OSG I have to do it in the reverse order : Code: osg::Vec4 result = vertex * matrix; Is it due to the Matrices major mode that are different from OpenGL and

Re: [osg-users] [3rdparty] ImGui integration

Hi Everyone, I was thinking to integrate ImGUI with the non FPP version but I'm not sure how to do it. Itself, ImGUI render the ui inside a vector of (vector of ) struct containing the triplet Vertex Position, UV coordinates and Color value. As it's and "immediate GU", It refresh and refill

[osg-users] Displaying the normals of your models

Hi everyone, I have to debug a normal issue with my model, so I made a code to display them (transform normals in a bunch of gl_lines and create a resulted geometry). I share the gist in case it may help: https://gist.github.com/fulezi/95a9ac319fd1cbeca1b18a4cde3986dc Have a nice day,

Re: [osg-users] Unexpected different lightening

Hi Tang, You should be right has the normals are incorrect anyway. I've maybe messed up my copy-past debug and have to dig it more. Thanks for you answer :) Cheers, Florian -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=72503#72503

Re: [osg-users] Mouse position to object space

Hi Hakan, If you want to simply drag (or do other transformation to) an object you can use the Dragger from the osgManipulator pluggin: Code: osgManipulator::TranslateAxisDragger Otherwise you need to project the mouse to the world space. If I recall correctly: Code:

[osg-users] Unexpected different lightening

Hi everyone, I've exported a blender scene with the osgexport module (https://github.com/cedricpinson/osgexport) however the lightening is not as bright as expected (see screenshot). I've exported the same scene as wavefront (.obj) and it renders correctly. Then I converted the .obj into a

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

Re: [osg-users] Multiples scenes

Hi Robert I gave a look to the osg::Switch and it's interesting too! I don't need to mix the two scenes, in addition I need to restore the position and the animation of the monsters. So I've opted for the "viewer.setSceneData(newModel);". It works well so far! Thanks for your answer! Florian

Re: [osg-users] clamp mouse cursor / position

Hi Sebastian, I'm not an expert, but in my case I've my own class overloading osgGA::StandardManipulator. In this case, while overriding the method handleMouseMove I can call requestWarpPointer without recusiving call handleMouseMove. Is it what you are looking for? Best, Florian

Re: [osg-users] Multiples scenes

Hi Robert, The player just move to a new scene so the previous one can be discarded. By scene I wanted to mean the "root" node and all its children, and the callback, keeping only the view and the camera manipulator. In the application, the player walk along a maze (an interior scene) and when

Hi everyone I'm looking for the method to go from a scene to another one. I've found that setting a new model scene works but is it the preferred way? Code: /* Changing the scene on the fly in a osg::NodeCallback */ viewer.setSceneData(scene2); Thanks, Florian -- Read this

Re: [osg-users] Using multiples texture for a geometry

Hi Robert, hi Sebastian, Thanks for your help so far Robert, I hope you have a good trip in Germany! Sebastian, thanks for your help, I understand what you mean. Because I used 0's for my texture mapping I was binding "void". That's why it appeared black. On your example, I got the two

Re: [osg-users] Using multiples texture for a geometry

Hi Robert, I followed your suggestion and indeed the exported scenes seem different but I don't get this difference. Please see in attachment for the source code and the exported scenes. This source code create one drawable with two faces and two TextCoords buffers. The result is the same: if

Hi Robert, I tried without the SmoothingVisitor but it does not change anything. However during my tests today I put a "Axes" object (the axes.osgt model from the OpenSceneGraph examples) and some part of the texture on the block below the object just appeared but really dark. So it it make

Hi Robert, Thanks for your response! I might have the two vectors for the textures coordinate. Basically my idea is to have cubes to draw Labyrinth. I read a file such as: Code: x x.x x Where 'x' represents a wall. I've a class named Level that hold two Vec2Array for the two

Hi Christian, Thanks for your answer. Indeed using 4 faces solved the situation, now I've a cube fully textured. I've also change from triangles to quads. I don't know if I've eared anything. I add the code below (it may help someone else). Code: osg::ref_ptr vertices = new osg::Vec3Array;
