Re: [osg-users] No texture with setUseVertexAttributeAliasing enabled

Hi! I am working with modern Opengl so that I have to use setUseVertexAttributeAliasing(true) to get proper normals in shaders. The problem is that the elements not processed by shaders are not showing their textures. I have found something similar in this topic and it seem pretty much the

Re: [osg-users] No texture with setUseVertexAttributeAliasing enabled

Thanks for your reply! Yes, I am using osg_ suffix instead gl_. The only gl_ variable that I am using is gl_Position, but I think this is OK - correct me if I am wrong. Actually my shader is very simple. I am just trying to draw the raw normals of the cow. The problem with the textures cames

Hi, I tried to fix it with no success, any suggestion? Thanks! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=60770#60770 ___ osg-users mailing list osg-users@lists.openscenegraph.org

Re: [osg-users] No texture with setUseVertexAttributeAliasing enabled

The color of the walls could be texture coordinates as you says, it sounds convincing. But, anyway, I tried adding some normals for testing with following code but it is still not working: Code: osg::Vec3Array *normalArray = new osg::Vec3Array(); normalArray-push_back(osg::Vec3(0.0f,0.0f,

Re: [osg-users] No texture with setUseVertexAttributeAliasing enabled

Thanks Nick for the clarification. In my code I am doing Code: osg::StateSet* shaderState = cowG-getOrCreateStateSet(); ... shaderState-setAttributeAndModes(program, osg::StateAttribute::ON); that seems similar to your suggestion. The weird thing here is that geometries with no shaders

Re: [osg-users] No texture with setUseVertexAttributeAliasing enabled

Why is the attribute aliasing enabled in the first place? If I am not wrong I have to enable attribute aliasing to use osg_Normals from shaders. Have you tried loading a osg model and display it with your shader? The cow in ScreenShot168.png is rendered with my shader (It is a simple

Re: [osg-users] No texture with setUseVertexAttributeAliasing enabled

Looks okay. Still the osg_Normal might default to attribute slot 0, so it I still don't get what you are trying to achieve. I want to draw some walls with textures and a model with shaders. Should I render walls with a shader too? What do you mean with

[osg-users] Texture coordinates in shaders GLSL

Hi all, I am trying to draw an osg scene (lz.osg) with shaders. For that, I had to use the Visitor Pattern and so on. The problem that I am having is that I don't know how the texture coordinates are beeing uploaded to shaders. I was expecting that I could use osg_MultiTexCoord0 in a similar

Hi, You are right, I forgot use setUseVertexAttributeAliasing(true) Thank you very much for the tip! Best wishes -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=61288#61288 ___ osg-users mailing
